Abstract
Immune system (IS) functionality is warranted by inter-dependent processes that balance body defences without exceeding in inflammation. An ideal nutraceutical approach should sustain the protective IS activity while controlling inflammation. The potential immunomodulatory activity of the food supplement (FS) AminoDefence was studied in resting macrophages RAW264.7 and following stimulation of bacterial- and viral-associated inflammation trough LPS and PolyI:C treatments, respectively. In unstimulated macrophages, the formulation exerted a dose-dependent immunostimulant activity by up-regulating NO, IL-6, TNF-α and MCP-1 release, while it dampened the aberrant release of these factors induced by pro-inflammatory stimuli. Exploring the contribution of single components Echinacea purpurea (E. purpurea) extract and quercetin, used at proportional concentrations than in whole formulation, a more pronounced immunostimulant effect was observed for E. purpurea, and an anti-inflammatory activity for quercetin. Hence, AminoDefence exerts an immunomodulatory activity in macrophages by effectively stimulating a protective inflammatory response and limiting it in cases of excessive inflammation.

Abstract
Antioxidants are added to foods to decrease the adverse effect of reactive species that create undesirable compounds that destroy essential nutrients and, therefore, lower the nutritional, chemical and physical properties of foods. This study was carried out to determine the antioxidant properties of flowers and plant stems with leaves of Echinacea purpurea grown with mulches of different colours and thicknesses. Coneflowers were grown in the Experimental Station of the Agricultural University in Kraków, Poland. The mulching materials used were black, green and brown colours of 100 g/m2 and 80 g/m2 density. In plant material, e.g., flowers or plant stems plus leaves the proximate analysis, the total polyphenol content and the ability to scavenge free radicals (ABTS, DPPH and FRAP) were determined. The results show that flower samples had a higher content of compound proteins, ash and phenolic compounds. The mulching colour and density did not affect the proximate analysis of the E. purpurea plant. Based on the result of this study, E. purpurea is a potential source of natural antioxidants and can be used to improve the antioxidant activity of various food products as well as in cosmetics within the pharmaceutical industry.

Abstract
Echinacea purpurea (L.) Moench is a medicinal plant commonly used for the treatment of upper respiratory tract infections, the common cold, sore throat, migraine, colic, stomach cramps, and toothaches and the promotion of wound healing. Based on the known pharmacological properties of essential oils (EOs), we hypothesized that E. purpurea EOs may contribute to these medicinal properties. In this work, EOs from the flowers of E. purpurea were steam-distilled and analyzed by gas chromatography-mass spectrometry (GC-MS), GC with flame-ionization detection (GC-FID), and chiral GC-MS. The EOs were also evaluated for in vitro antimicrobial and innate immunomodulatory activity. About 87 compounds were identified in five samples of the steam-distilled E. purpurea EO. The major components of the E. purpurea EO were germacrene D (42.0 ± 4.61%), α-phellandrene (10.09 ± 1.59%), β-caryophyllene (5.75 ± 1.72%), γ-curcumene (5.03 ± 1.96%), α-pinene (4.44 ± 1.78%), δ-cadinene (3.31 ± 0.61%), and β-pinene (2.43 ± 0.98%). Eleven chiral compounds were identified in the E. purpurea EO, including α-pinene, sabinene, β-pinene, α-phellandrene, limonene, β-phellandrene, α-copaene, β-elemene, β-caryophyllene, germacrene D, and δ-cadinene. Analysis of E. purpurea EO antimicrobial activity showed that they inhibited the growth of several bacterial species, although the EO did not seem to be effective for Staphylococcus aureus. The E. purpurea EO and its major components induced intracellular calcium mobilization in human neutrophils. Additionally, pretreatment of human neutrophils with the E. purpurea EO or (+)-δ-cadinene suppressed agonist-induced neutrophil calcium mobilization and chemotaxis. Moreover, pharmacophore mapping studies predicted two potential MAPK targets for (+)-δ-cadinene. Our results are consistent with previous reports on the innate immunomodulatory activities of β-caryophyllene, α-phellandrene, and germacrene D. Thus, this study identified δ-cadinene as a novel neutrophil agonist and suggests that δ-cadinene may contribute to the reported immunomodulatory activity of E. purpurea.

Abstract
OBJECTIVE Polyphenols are complex compounds containing multiple phenolic hydroxyl groups. They are widely distributed in plants and have antioxidant activities. Whether the antioxidant activities of the cultivated varieties of Echinacea are similar to or better than those of the wild ones and the relationship between the accumulation of polyphenols and their antioxidant activities are still not clear. METHODS Folin-Ciocalteu method, high performance liquid chromatography (HPLC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, ferric ion reducing antioxidant power (FRAP) assay, 2,2'-azino-bis(3-ethylbenzothiazoline-6)-sulfonic acid (ABTS) radical scavenging assay, and Fe2+ chelating ability assay were used, respectively, to detect the total polyphenols and 5 kinds of caffeic acid derivatives (chicoric acid, caffeic acid, caftaric acid, chlorogenic acid, and 1,5-dicaffeoylquinic acid) in the roots, stems, leaves, and flowers, and the antioxidant activities of 3 varieties of Echinacea: E. purpurea L., cultivar E. purpurea 'Aloha', and E. purpurea 'White Swan'. RESULTS E. purpurea L. had the highest contents of total polyphenols, 5 caffeic acid derivatives and antioxidant activities, followed by E. purpurea 'White Swan' and E. purpurea 'Aloha', respectively. E. purpurea 'White Swan' had the strongest ability to remove the DPPH, ABTS•+ and free radicals, and to chelate Fe2+; E. purpurea L. had the strongest ability to reduce FRAP. The correlation analyses revealed that the contents of total polyphenols and caffeic acid derivatives of E. purpurea L. and E. purpurea 'White Swan' were correlated with their antioxidant activities. CONCLUSION E. purpurea L. was the most appropriate material for the development of medicinal plants. E. purpurea 'White Swan' could be used as a substitute for E. purpurea L. in terms of its antioxidant activity.

Abstract
Achieving and maintaining a well-balanced immune system has righteously become an insightful task for the general population and an even more fundamental goal for those affected by immune-related diseases. Since our immune functions are indispensable in defending the body against pathogens, diseases and other external attacks, while playing a vital role in maintaining health and modulating the immune response, we require an on-point grasp of their shortcoming as a foundation for the development of functional foods and novel nutraceuticals. Seeing that immunoceuticals are considered effective in improving immune functions and reducing the incidence of immunological disorders, the main focus of this study was to assess the immunomodulatory properties and possible acute toxicity of a novel nutraceutical with active substances of natural origin on C57BL/6 mice for 21 days. We evaluated the potential hazards (microbial contamination and heavy metals) of the novel nutraceutical and addressed the acute toxicity according to OECD guidelines of a 2000 mg/kg dose on mice for 21 days. The immunomodulatory effect was assessed at three concentrations (50 mg/kg, 100 mg/kg and 200 mg/kg) by determining body and organ indexes through a leukocyte analysis; flow cytometry immunophenotyping of lymphocytes populations and their subpopulations (T lymphocytes (LyCD3+), cytotoxic suppressor T lymphocytes (CD3+CD8+), helper T lymphocytes (CD3+CD4+), B lymphocytes (CD3-CD19+) and NK cells (CD3-NK1.1.+); and the expression of the CD69 activation marker. The results obtained for the novel nutraceutical referred to as ImunoBoost indicated no acute toxicity, an increased number of lymphocytes and the stimulation of lymphocyte activation and proliferation, demonstrating its immunomodulatory effect. The safe human consumption dose was established at 30 mg/day.

Abstract
Alzheimer's disease (AD) is one of the neurodegenerative illnesses that impair individual life & increase the demand for caregivers with no available curative medication right now. Therefore, there is a growing concern about employing herbal medicine to limit AD progression & improve patients' life quality, thus potentiating its add-on therapy. In addition, herbs are cost-effective & accessible with nearly no side effects. In the same vein, our study aimed to investigate the potency of Echinacea purpurea (EP) flower extracts to ameliorate the neurodegenerative effect of Aluminum chloride (AlCl3) in a rat model. Moreover, mechanistic studies, including impact on the cholinesterase activity, redox status, inflammatory mediators, behavior performance, glucose level & histopathology, were carried on. Our results showed that 250 mg/kg of Aqueous (AQ) & Alcoholic (AL) extracts of EP inhibited cholinesterase, restored oxidative balance, down-regulated IL-6 & TNF-α cytokines & improved behavior performance in vivo that was reflected in the brain picture by decreasing neuronal degeneration & amyloid plaques in cerebral cortex & hippocampus. The potency of both extracts was compared to reference drugs & AlCl3 positive control group. The AQ extract showed greater potency against COX-1, COX-2 & α-amylase in vitro, while the AL extract was more potent against cholinesterase in vitro, inflammatory cytokines, behavior & pathological improvement in vivo. Conclusively EP overcame AlCl3-induced neurobehavioral toxicity in the rat model via different pathways, which support its regular administration to postpone progressive neural damage in AD patients.

Abstract
Important evidence is reported on the antimicrobial and antagonistic properties of bacterial endophytes in Echinacea purpurea and their role in the modulation of plant synthesis of bioactive compounds. Here, endophytic fungi were isolated from E. purpurea, and the dual culture approach was applied to deepen insights into the complex plant-microbiome interaction network. In vitro experiments were carried out to evaluate the species specificity of the interaction between host (E. purpurea) and non-host (E. angustifolia and Nicotiana tabacum) plant tissues and bacterial or fungal endophytes isolated from living E. purpurea plants to test interactions between fungal and bacterial endophytes. A higher tropism towards plant tissue and growth was observed for both fungal and bacterial isolates compared to controls without plant tissue. The growth of all fungi was significantly inhibited by several bacterial strains that, in turn, were scarcely affected by the presence of fungi. Finally, E. purpurea endophytic bacteria were able to inhibit mycelial growth of the phytopathogen Botrytis cinerea. Bacteria and fungi living in symbiosis with wild Echinacea plants interact with each other and could represent a potential source of bioactive compounds and a biocontrol tool.

Abstract
Echinacea purpurea is a plant with immunomodulating properties, often used in topical preparations for treatment of small superficial wounds. In the presented study, the best conditions for ultrasound-assisted extraction of caffeic acid derivatives (caftaric and cichoric acid) (TPA-opt extract), as well as the conditions best suited for preparation of the extract with high radical scavenging activity (RSA-opt extract), from E. purpurea aerial parts were determined. A Box-Behnken design based on glycerol content (%, w/w), temperature (°C), ultrasonication power (W) and time (min) as independent variables was performed. Antioxidant, antiaging and wound healing effects of the two prepared extracts were evaluated. The results demonstrate that glycerol extraction is a fast and efficient method for preparation of the extracts with excellent radical scavenging, Fe2+ chelating and antioxidant abilities. Furthermore, the extracts demonstrated notable collagenase, elastase and tyrosinase inhibitory activity, indicating their antiaging properties. Well-pronounced hyaluronidase-inhibitory activities, with IC50 values lower than 30 μL extract/mL, as well as the ability to promote scratch closure in HaCaT keratinocyte monolayers, even in concentrations as low as 2.5 μL extract/mL (for RSA-opt), demonstrate promising wound healing effects of E. purpurea. The fact that the investigated extracts were prepared using glycerol, a non-toxic and environmentally friendly solvent, widely used in cosmetics, makes them suitable for direct use in specialized cosmeceutical formulations.

Abstract
Background Echinacea purpurea has clinical antiviral activity against respiratory viruses and modulates immune functions. In this study, we compared higher doses of new Echinacea formulations with conventional formulations at lower, preventive doses for therapy of respiratory tract infections (RTIs). Methods In this randomized, blinded, controlled trial, healthy adults (n = 409) were randomized between November 2018 and January 2019 to one of four Echinacea formulations, which were taken in case of an RTI for up to 10 days. New formulations A (lozenges) and B (spray) delivered an increased dose of 16,800 mg/d Echinacea extract during days 1-3 and 2,240-3,360 mg/d afterward; as controls, conventional formulations C (tablets) and D (drops) delivered a lower daily dose of 2,400 mg, usually taken for prevention. The primary endpoint was time to clinical remission of first RTI episodes based on the Kaplan-Meier analysis of patient-reported, investigator-confirmed, respiratory symptoms assessed for up to 10 days. In a sensitivity analysis, the mean time to remission beyond day 10 was calculated by extrapolating the treatment effects observed on days 7 to 10. Results A total of 246 participants (median age 32 years, 78% female participants) were treated for at least one RTI. Recovery by day 10 (complete absence of symptoms) was achieved in 56 and 44% of patients with the new and conventional formulations, respectively, showing a median time to recovery of 10 and 11 days, respectively (p = 0.10 in intention-to-treat analysis, p = 0.07 in per-protocol analysis). In the extrapolated sensitivity analysis, new formulations resulted in a significantly shorter mean time to remission (9.6 vs. 11.0 days, p < 0.001). Among those with an identified respiratory virus, viral clearance until day 10 based on real-time PCR from nasopharyngeal swabs was more frequent with new formulations (70 vs. 53%, p = 0.046). Tolerability and safety (adverse events: 12 vs. 6%, p = 0.19) were good and similar between formulations. There was one severe adverse event with a potential hypersensitivity reaction in a recipient of the novel spray formulation. Conclusion In adults with acute RTI, new Echinacea formulations with higher doses resulted in faster viral clearance than conventional formulations in prophylactic dosages. The trend for faster clinical recovery was not significant by day 10 but became so upon extrapolation. A dose increase during acute respiratory symptoms might improve the clinical benefits of orally administered Echinacea formulations. Trial registration The study was registered in the Swiss National Clinical Trials Portal (SNCTP000003069) and on ClinicalTrials.gov (NTC03812900; URL https://clinicaltrials.gov/ct2/show/NCT03812900?cond=echinacea&draw=3&rank=14).

Abstract
Chemotherapy-induced neuropathy represents the main dose-limiting toxicity of several anticancer drugs, such as oxaliplatin, leading to chronic pain and an impairment of the quality of life. Echinacea purpurea n-hexane extract (EP4 -RE ; rich in alkamides) and butanolic extract (EP4 -RBU ; rich in polyphenols) have been characterized and tested in an in vivo model of oxaliplatin-induced neuropathic pain, addressing the endocannabinoid system with alkamides and counteracting the redox imbalance with polyphenols. Thermal hypersensitivity was evaluated by the Cold Plate test. EP4 -RE showed a dose-dependent anti-hyperalgesic profile. The extract was more effective than its main constituent, dodeca-2 E,4 E,8Z,10 E/Z-tetraenoic acid isobutylamide (18 mg kg-1 , twofold to equimolar EP4 -RE 30 mg kg-1 ), suggesting a synergy with other extract constituents. Administration of cannabinoid type 2 (CB2) receptor-selective antagonist completely blocked the anti-allodynic effect of EP4 -RE , differently from the antagonism of CB1 receptors. EP4 -RBU (30 mg kg-1 ) exhibited anti-neuropathic properties too. The effect was mainly exerted by chicoric acid, which administered alone (123 μg kg-1 , equimolar to EP4 -RBU 30 mg kg-1 ) completely reverted oxaliplatin-induced allodynia. A synergy between different polyphenols in the extract had not been highlighted. Echinacea extracts have therapeutic potential in the treatment of neuropathic pain, through both alkamides CB2-selective activity and polyphenols protective properties.

Abstract
Background Oral lichen planus (OLP) is a chronic immune-mediated mucocutaneous disorder, with an unknown etiology. Since, both pain and discomfort are observed in patients with the erosive type, many drugs have been studied to alleviate pain and clinical symptoms. The present study aimed to assess the effectiveness of systemic Echinacea on clinical indices of OLP. Materials and Methods In this randomized, double-blind, placebo-controlled trial, 70 patients with erosive OLP were randomly divided into two groups, and each was treated with Echinacea tablets or placebo, 3 times a day, for 35 days. In addition, betamethasone lotion (0.1%) or nystatin (100,000 units) mouthwash were used by patients. The pain severity (visual analog scale [VAS]), lesion size, and the number of lesions were assessed at baseline and on days 10, 25, and 35 after study initiation. Finally, the obtained data were analyzed by statistical software, and Mann-Whitney test, Wilcoxon test, KaplanMeier, Chi-squared, and paired t-test. Results The VAS scores in the Echinacea group were significantly reduced at each visit compared to the placebo group (P < 0.001). We observed a significant difference between the two groups (P < 0.01). Conclusion We showed that Echinacea is an effective and complementary therapy for OLP. Furthermore, in short-term usage, Echinacea is almost completely tolerable.

Abstract
Dental caries and oral infections have become a widespread issue in the modern world. This study aimed to investigate the antibacterial, antifungal, and cytotoxicity characteristics of the extracts of Echinacea purpura, Arctium lappa, and the essential oil of Zataria multiflora as a potential herbal mouthwash. The essential oil of Z. multiflora leaves and the extracts of E. purpurea and A. lappa roots were prepared. The characterization was carried out by GC-MS and also, total phenol and flavonoid were assed for all three samples. The antimicrobial and anti-biofilm effects were evaluated against Streptococcus mutans, Streptococcus mitis, Streptococcus salivarius, Lactobacillus acidophilus, Escherichia coli, Staphylococcus aureus, and Candida albicans. The cytotoxic effect of the samples was evaluated on HEK 293 and HDFa cells by MTT test. Thymol and carvacrol contents in EO of Z. multiflora were measured at 31% and 42.2%, respectively. A. lappa had the lowest total phenolic and flavonoid value among the samples. On the other hand, the total phenolic content of Z. multiflora and the total flavonoid content of E. purpurea were the highest. The MIC values of Zataria, Arctium, and Echinacea against S. mutans were 0.011% v/v, 187.5 mg/ml, and 93.75 mg/ml, while MBC were 0.011% v/v, 375 mg/ml, and 187.5 mg/ml, respectively. The formulation showed bactericidal activity against S. mutans in the concentration of 5.86 mg/ml for Echinacea and Burdock extracts and 0.08 µl/ml for EO of Zataria. The formulation significantly affected microbial biofilm formation and induced biofilm degradation. The cell viability percentages were higher than 50% during 24 and 48 h. The formulation had a significant antimicrobial effect on cariogenic bacteria and C. albicans, with the lowest cytotoxic effects. Therefore, this formulation can be an appropriate candidate for mouthwash.

Abstract
SARS-CoV-2 vaccination is effective in preventing severe Covid-19, but efficacy in reducing viral load and transmission wanes over time. In addition, the emergence of novel SARS-CoV-2 variants increases the threat of uncontrolled dissemination and additional antiviral therapies are urgently needed for effective containment. In previous in vitro studies Echinacea purpurea demonstrated strong antiviral activity against enveloped viruses, including SARS-CoV-2. In this study, we examined the potential of Echinacea purpurea in preventing and treating respiratory tract infections (RTIs) and in particular, SARS-CoV-2 infections. 120 healthy volunteers (m,f, 18-75 years) were randomly assigned to Echinacea prevention or control group without any intervention. After a run-in week, participants went through 3 prevention cycles of 2, 2 and 1 month with daily 2,400 mg Echinacea purpurea extract (Echinaforce®, EF). The prevention cycles were interrupted by breaks of 1 week. Acute respiratory symptoms were treated with 4,000 mg EF for up to 10 days, and their severity assessed via a diary. Naso/oropharyngeal swabs and venous blood samples were routinely collected every month and during acute illnesses for detection and identification of respiratory viruses, including SARS-CoV-2 via RT-qPCR and serology. Summarized over all phases of prevention, 21 and 29 samples tested positive for any virus in the EF and control group, of which 5 and 14 samples tested SARS-CoV-2 positive (RR = 0.37, Chi-square test, p = 0.03). Overall, 10 and 14 symptomatic episodes occurred, of which 5 and 8 were Covid-19 (RR = 0.70, Chi-square test, p > 0.05). EF treatment when applied during acute episodes significantly reduced the overall virus load by at least 2.12 log10 or approx. 99% (t-test, p < 0.05), the time to virus clearance by 8.0 days for all viruses (Wilcoxon test, p = 0.02) and by 4.8 days for SARS-CoV-2 (p > 0.05) in comparison to control. Finally, EF treatment significantly reduced fever days (1 day vs 11 days, Chi-square test, p = 0.003) but not the overall symptom severity. There were fewer Covid-19 related hospitalizations in the EF treatment group (N = 0 vs N = 2). EF exhibited antiviral effects and reduced the risk of viral RTIs, including SARS-CoV-2. By substantially reducing virus loads in infected subjects, EF offers a supportive addition to existing mandated treatments like vaccinations. Future confirmatory studies are warranted.

Abstract
Since the teratogenicity of Thalidomide has been proven, herbal products are more commonly used in pregnancy to not only relieve morning sickness but also to fight infections. These products are frequently considered as natural and therefore harmless. However, herbs contain a number of active substances that, when used during pregnancy, can affect the development of the fetus. Often, pregnant women do not consult the usage of herbal medicines with a physician. The access to these products is easy and treatment of certain ailments with the use of herbs is common in many countries. The aim of the present literature review was to discuss available data regarding the efficacy and safety of cranberry, chamomile, Echinacea purpurea, garlic, ginger, Ginkgo biloba, and peppermint, which are used to counteract the most common ailments during pregnancy, i.e., infections and pregnancy-related ailments (e.g., nausea and vomiting, dizziness, and headache). Analysis of available data showed that ginger is one of the most extensively analyzed herbal remedies. The dose of ginger below 1000 mg per day may help to relief hypereremesis gravidarum, and such an amount of ginger did not increase frequency of adverse effects for either woman or developing fetus. Data regarding other herbs are most often heterogeneous and give conflicting results with no clear conclusions. However, all herbal products should be used with a special caution in pregnancy. Further high-quality human studies should be determined to confirm the safe doses of herbal products which could be used by pregnant or breast-feeding women.

Abstract
Echinacea purpurea (L.) Moench (Ep) is widely used as a kind of dietary supplements, and possesses various pharmacological activities, including immunomodulatory, anti-inflammatory, antitumor effects. However, the inhibitory effects of Ep on the growth and metastasis of hepatocellular carcinoma (HCC) is unclear. Here, the preventive effect and potential mechanism of Ep on HCC was elucidated by systems pharmacology and molecular docking. The results showed that Ep could significantly ameliorate HCC-induced tumor growth and migration in vivo and in vitro. System pharmacology results indicated that 180 genes associated with HCC were regarded as the potential therapeutic targets of Ep, mainly involved in metabolic pathways, cancer pathways, proteoglycans in cancer and PI3K/Akt signaling pathway, which might be a crucial pathway in HCC EMT. A herb-component-target-pathway network was constructed to reveal the interactions between Ep and HCC. Finally, predicted PI3K/Akt pathway was further validated by molecular docking and western blot experiment. This study showed that Ep ameliorates HCC-induced tumor cell survival and migration in mice via the regulation of the PI3K/Akt pathway. Thus, Ep might be a potential new strategy to prevent the growth and metastasis of HCC.

Abstract
The objective of this randomized, placebo-controlled, double-blinded field trial was to investigate the effects of oral administration of purple coneflower (Echinacea purpurea L. (EP)) on performance, health and immune parameters in calves. Calves (n = 27) were enrolled to three groups (9 calves per group): 0.5 g EP/calf per day (ECL), 5 g EP/calf per day (ECH) or placebo. Calves were vaccinated with Bluetongue-Virus (BTV) serotype 4 vaccine to investigate EPs effects on seroconversion. Clinical and performance parameters, inter alia body weight, health and milk intake were recorded for 57 days. Blood samples were analyzed for BTV antibodies and IgG by ELISA, white and red blood cell counts by flow cytometry and mRNA abundance of various inflammatory markers in leukocytes (IL-1β, IL-8, tumor necrosis factor α (TNFα), cyclooxygenase 2 (Cox-2) and prostaglandin E synthase) was studied. The findings demonstrated no differences between groups regarding performance parameters. In all groups, calves suffered from diarrhea for a minimum of 2 days, but EP reduced the number of diarrhea days by 44% in ECL and increased the body temperature. Interestingly, ECL resulted in an increased number of respiratory disease days during the follow-up period. EP did not change blood cell and IgG counts, whereas eosinophil granulocytes were reduced in ECL. Decreased levels of hemoglobin and hematocrit were found in ECH. Prostaglandin E synthase levels in leukocytes were higher in ECL and ECH, whereas no differences were obtained for IL-1β, IL-8, TNFα and Cox-2. Due to the unexpected occurrence of BTV seropositive calves before the first vaccination, 13 calves were excluded from the evaluation on seroconversion and no statistical analyses could be performed regarding antibody production. BTV-4 antibodies were not produced in 4 placebo-calves, whereas 4 of 5 and 1 of 6 ECL- and ECH-calves produced antibodies. Further investigations are needed to draw final conclusions on mode of action and efficacy of EP in calves.

Abstract
As lifestyle changes, the prevalence of diabetes increases every year. Diabetes-induced male reproductive dysfunction is predominantly due to increased oxidative stress and then results in sperm damage and infertility. Echinacea purpurea is a traditional medicinal herb and is well-known for its immune-modulatory, antioxidative, anti-inflammatory, anticancer, and antiviral activities. The Toll-like receptor 4 (TLR4) plays a critical role in innate immune responses leading to nuclear factor (NF)-κB phosphorylation and release of proinflammatory cytokines including nitric oxide (NO), interleukin (IL)-1β, and tumor necrosis factor (TNF)-α. However, the relation between Echinacea purpurea extract and TLR4 remains unclear. This study aimed to investigate the protective effects on male reproduction of Echinacea purpurea ethanol extract (EPE) against diabetic rats and whether the anti-inflammatory effects were through the TLR4 pathway. Diabetic male Sprague-Dawley (SD) rats were induced by streptozotocin (65 mg/kg) and nicotinamide (230 mg/kg). EPE was tested in three doses (93, 279, and 465 mg/kg p.o. daily) for 4 weeks. Besides, metformin administration (100 mg/kg/day) was treated as a positive control. Results indicated that EPE administration for about 4 weeks improved hyperglycemia and insulin resistance. Additionally, EPE increased sperm motility, protected sperm morphology and mitochondrial membrane potential, as well as protein for testosterone synthesis enzyme. In sperm superoxide dismutase, catalase, and glutathione antioxidants were increased, whereas proinflammatory cytokines, such as NO, IL-1β, and TNF-α were decreased. The testis protein content of TLR4 and downstream phospho-NF-κB p65 also were reduced. The EPE might reduce the production of proinflammatory cytokines via TLR4 pathways and improve diabetes-induced male infertility.

Here, we report on studies on the influence of different crosslinking methods (ionic and chemical) on the physicochemical (swelling ability and degradation in simulated body fluids), structural (FT-IR spectra analysis) and morphological (SEM analysis) properties of SA/PVA hydrogels containing active substances of natural origin. First, an aqueous extract of Echinacea purpurea was prepared using a Soxhlet apparatus. Next, a series of modified SA/PVA-based hydrogels were obtained through the chemical crosslinking method using poly(ethylene glycol) diacrylate (PEGDA, Mn = 700 g/mol) as a crosslinking agent and, additionally, the ionic reaction in the presence of a 5% w/v calcium chloride solution. The compositions of SA/PVA/E. purpurea-based hydrogels contained a polymer of natural origin-sodium alginate (SA, 1.5% solution)-and a synthetic polymer-poly(vinyl alcohol) (PVA, Mn = 72,000 g/mol, 10% solution)-in the ratio 2:1, and different amounts of the aqueous extract of E. purpurea-5, 10, 15 or 20% (v/v). Additionally, the release behavior of echinacoside from the polymeric matrix was evaluated in phosphate-buffered saline (PBS) at 37 °C. The results indicate that the type of the crosslinking method has a direct impact on the release profile. Consequently, it is possible to design a system that delivers an active substance in a way that depends on the application.

Abstract
Galectins represent β-galactoside-binding proteins with numerous functions. Due to their role in tumor progression, human galectins-1, -3 and -7 (Gal-1, -3 and -7) are potential targets for cancer therapy. As plant derived glycans might act as galectin inhibitors, we prepared galactans by partial degradation of plant arabinogalactan-proteins. Besides commercially purchased galectins, we produced Gal-1 and -7 in a cell free system and tested binding capacities of the galectins to the galactans by biolayer-interferometry. Results for commercial and cell-free expressed galectins were comparable confirming functionality of the cell-free produced galectins. Our results revealed that galactans from Echinacea purpurea bind to Gal-1 and -7 with KD values of 1–2 µM and to Gal-3 slightly stronger with KD values between 0.36 and 0.70 µM depending on the sensor type. Galactans from the seagrass Zostera marina with higher branching of the galactan and higher content of uronic acids showed stronger binding to Gal-3 (0.08–0.28 µM) compared to galactan from Echinacea. The results contribute to knowledge on interactions between plant polysaccharides and galectins. Arabinogalactan-proteins have been identified as a new source for production of galactans with possible capability to act as galectin inhibitors.

Abstract
Echinacea purpurea is a plant cultivated worldwide for its pharmaceutical properties, mainly related to the stimulation of the immune system in the treatment of respiratory infections. The cypselas (fruits) of E. purpurea were examined in order to investigate the presence, localization and potential function(s) of endophytic microorganisms. Electron and confocal microscopy observations showed that three different components of microorganisms were associated to cypselas of E. purpurea: (i) one endocellular bacterial component in the cotyledons, enclosed within the host membrane; (ii) another more generic bacterial component adhering to the external side of the perianth; and (iii) a fungal component inside the porous layer of the perianth, the woody and porous modified residual of the flower, in the form of numerous hyphae able to cross the wall between adjacent cells. Isolated bacteria were affiliated to the genera Paenibacillus, Pantoea, and Sanguibacter. Plate tests showed a general resistance to six different antibiotics and also to an antimicrobial-producing Rheinheimera sp. test strain. Finally, microbiome-deprived E. purpurea seeds showed a reduced ability to germinate, suggesting an active role of the microbiome in the plant vitality. Our results suggest that the endophytic bacterial community of E. purpurea, previously found in roots and stem/leaves, might be already carried at the seed stage, hosted by the cotyledons. A further microbial fungal component is transported together with the seed in the perianth of the cypsela, whose remarkable structure may be considered as an adaptation for fungal transportation, and could influence the capability of the seed to germinate in the soil.Key Points• The fruit of Echinacea purpurea contains fungi not causing any damage to the plant.• The seed cotyledons contain endocellular bacteria.• Seed/fruit deprived of the microbiome showed a reduced ability to germinate.

Abstract
Histamine and leukotrienes (LTs), the chemical mediators released from mast cells, play an important role in type-I allergies such as hay fever. Echinacea purpurea (EP) has traditionally been used for herbal tea and has been reported to show biological functions. We evaluated the inhibitory activity of water extracts of EP petals, leaves, and stems against the chemical mediators released from mast cell lines. Petal and leaf extracts exhibited a significant inhibitory effect on histamine release from the stimulated cells, while the stem extract did not exert any effect. Activity of the petal extract was much stronger than that of the leaf extract. All the extracts significantly suppressed LTB4 production in the stimulated cells and displayed similar activities. The petal extract decreased Syk phosphorylation and Ca2+ influx associated with signal transduction in the stimulated cells. These results suggest that EP petal extract may have a relieving effect on allergic symptoms.

Abstract
Preparations of Echinacea purpurea (E. purpurea) are widely used for the management of upper respiratory infections, influenza, and common cold, often in combination with other conventional drugs. However, the potential of phytochemical constituents of E. purpurea to cause herb-drug interactions via ABCB1 and ABCG2 efflux transporters remains elusive. The purpose of this study was to investigate the impact of E. purpurea-derived caffeic acid derivatives (cichoric acid and echinacoside) and tetraenes on the mRNA and protein expression levels as well as on transport activity of ABCB1 and ABCG2 in intestinal (Caco-2) and liver (HepG2) cell line models. The safety of these compounds was investigated by estimating EC20 values of cell viability assays in both cell lines. Regulation of ABCB1 and ABCG2 protein in these cell lines were analyzed after 24 h exposure to the compounds at 1, 10, and 50 μg/mL. Bidirectional transport of 0.5 μg/mL Hoechst 33342 and 5 μM rhodamine across Caco-2 monolayer and profiling for intracellular concentrations of the fluorophores in both cell lines were conducted to ascertain inhibition effects of the compounds. Cichoric acid showed no cytotoxic effect, while the EC20 values of tetraenes and echinacoside were 45.0 ± 3.0 and 52.0 ± 4.0 μg/mL in Caco-2 cells and 28.0 ± 4.3 and 62.0 ± 9.9 μg/mL in HepG2 cells, respectively. In general, the compounds showed heterogeneous induction of ABCB1 with the strongest 3.6 ± 1.2-fold increase observed for 10 μg/mL tetraenes in Caco-2 cells (p < 0.001). However, the compounds did not induce ABCG2. None of the phytocompounds inhibited significantly net flux of the fluorophores across Caco-2 monolayers. Overall, tetraenes moderately induced ABCB1 but not ABCG2 in Caco-2 and HepG2 cells while no compound significantly inhibited activity of these transporters at clinically relevant concentration to cause herb-drug interactions.

Abstract
Echinacea purpurea is used in herbal medicinal products for the prevention and treatment of the common cold, as well as for skin disorders and minor wounds. In this study, the efficiency of traditional maceration using water and ethanol was compared with the maceration using mixtures of water and glycerol, a non-toxic, biodegradable solvent from renewable sources. It was found that the glycerol-water mixtures were as effective as ethanol/water mixtures for the extraction of caffeic acid derivatives. All the prepared extracts demonstrated notable antiradical properties. Furthermore, an efficient ultrasound-assisted extraction using glycerol-water mixtures was developed using six independent variables. Their levels needed for the maximum extraction of caffeic acid derivatives were as follows: glycerol 90% (m/m), temperature 70 °C, ultrasound power 72 W, time 40 min, and ascorbic acid 0 mg/mL. Under the optimized conditions, ultrasound-assisted extraction was superior to maceration. It achieved significantly higher yields of phenolic acids in shorter extraction time. The presence of zinc in plant material may contribute to the beneficial effects of E. purpurea preparations. Since glycerol is a non-toxic solvent with humectant properties, the prepared extracts can be directly used for the preparation of cosmetics or oral pharmaceutical formulations without the need for solvent removal.

Abstract
Botanical dietary supplements (BDS) are used around the world for many purported therapeutic properties. The selection of an authentic product and it's phytochemical characterization is critical to generate robust safety data. Because botanicals are complex mixtures with variable quality, identification of a representative product for testing has been challenging. Echinacea is used for its purported immune stimulant properties and was listed as the 2nd top-selling BDS in 2018. However, there are limited safety data for Echinacea. Hence, the National Toxicology Program (NTP) has selected Echinacea for safety testing using rodent models. Here, we describe selection and comprehensive characterization of an Echinacea purpurea root extract to be used in the NTP testing program. Using non-targeted chemical analyses combined with chemometric analysis, a potential unfinished product (i.e., an extract that serves as source material for finished products) of Echinacea purpurea was selected. The product was then authenticated using chemical and DNA techniques and characterized, including the phytochemical composition. Among numerous constituents identified, caftaric acid, chicoric acid, chlorogenic acid and dodeca-2(E),4(E),8(Z),10(E/Z)-tetraenoic acid isobutylamide made up a small fraction of the extract. Based on these analyses, an approach is proposed for test article selection for Echinacea research which can be adapted to other botanicals.

Abstract
This study is aimed to appraise the impact of dietary supplementation with Echinacea purpurea (EP) in broiler chickens infected by pathogenic E. coli. Eighty-one-day-old chicks of both sexes, commercial Hubbard chicks, were divided into 4 groups. The first was kept as normal control, the second was supplemented by EP (5 mg/kg feed) from the first day to the end, where the third was infected orally by 1 ml E. coli O78 at 107 CFU intra-crop at 7 days old, while the last group was supplemented by EP and infected by the E. coli O78 as previously described . E. coli-infected chicks disclosed severe symptoms with mortality 30%. Where, the infected and EP supplemented group showed less clinical symptoms and 15% mortality. EP-supplemented groups showed a significant improvement in their body weight in comparing with infected group. E. coli-infected chickens revealed a significant drop in lymphocytes' number with a significant elevation in monocyte and heterophils with non-significant changes in total leucocyte count when matched with gp. (1), while the fourth group revealed non-significant changes in total leucocyte with a significant drop in heterophils and monocyte and a significant elevation in the lymphocytes matching with the 3rd group. Serum biochemical markers of liver, kidneys, and immunological parameters showed sever adverse alterations associated with E. coli infection. Dietary supplementations with Echinacea purpurea improve the final body weight and immune response of non-infected chicks and have a respectable effect for facing E. coli infection. EP improves hematological and serum biochemical adverse effects occured by E. coli infection. Histopathology of liver, kidneys, intestines, and spleen confirms these alterations.

Abstract
BACKGROUND Phylloxanthobilins are tetrapyrrolic natural products that arise from the degradation of chlorophyll. Phylloxanthobilins have been discovered roughly 10 years ago in the leaves of deciduous trees, and are now considered a compound class with high and still unexplored potential of bioactivities. To date, however, there are no reports on the occurrence of phylloxanthobilins in parts of a medicinal plant used for pharmaceutical preparations. PURPOSE The relevance of Echinacea purpurea as medicinal plant is undoubtedly high, and a large variety of pharmaceutical preparations is available on the market, mostly for the treatment of the common cold. Nevertheless, its phytochemical profiling has been limited to analysis for previously characterized substances, and this has not explained all its pharmacological efficacies. We therefore set out to investigate the occurrence of phylloxanthobilins in Echinacea purpurea. METHODS Phylloxanthobilins in leaf extracts of Echinacea purpurea were detected using analytical HPLC. Identified phyllobilins were purified from plant material and characterized by UV/Vis, mass spectrometry, MS/MS, and confirmed by co-injections with previously published phyllobilins from different sources. The anti-oxidant activity of selected isolated phylloxanthobilins was assessed by an in vitro ferric reducing antioxidant power (FRAP) assay; in addition, the ability to scavenge ROS in cells caused by hydrogen peroxide stimulation was determined by measuring H2DCF-DA fluorescence and by assessing cellular GSH levels. RESULTS In extracts of Echinacea purpurea leaves, an unprecedented diversity of phylloxanthobilins was detected; surprisingly, not only in senescent yellow leaves, but also in green leaves with no visible chlorophyll degradation. Six phylloxanthobilins were identified and structurally characterized. The uptake of phylloxanthobilins by human endothelial kidney cells was demonstrated. When investigating the anti-oxidative activity of these natural products, a potent in vitro activity was demonstrated; in addition, phylloxanthobilins possess intracellular ROS scavenging ability and can prevent oxidative stress as assessed by total cellular GSH levels. CONCLUSION Phylloxanthobilins are important constituents of Echinacea purpurea extracts, and our first exploratory studies hint towards promising bioactivities of these natural products, which may be relevant for understanding Echinacea efficacies.

Abstract
BACKGROUND Echinacea-endophyte interaction might affect plant secondary metabolites content and influence bacterial colonization specificity and plant growth, but the underlying mechanisms need deepening. An in vitro model, in which E. purpurea axenic plants as host species and E. angustifolia and Nicotiana tabacum as non-host species inoculated with single endophytes isolated from stem/leaf, root and rhizospheric soil, were used to investigate bacterial colonization. RESULTS Colonization analysis showed that bacteria tended to reach tissues from which they were originally isolated (tissue-specificity) in host plants but not in non-host ones (species-specificity). Primary root elongation inhibition as well as the promotion of the growth of E. purpurea and E. angustifolia plants were observed and related to endophyte-produced indole-3-Acetic Acid. Bacteria-secreted substances affected plant physiology probably interacting with plant regulators. Plant metabolites played an important role in controlling the endophyte growth. CONCLUSIONS The proposed in vitro infection model could be, generally used to identify novel bioactive compounds and/or to select specific endophytes contributing to the host metabolism properties.

Abstract
PURPOSE Cisplatin, one of the most effective anticancer drugs, is known to cause undesirable adverse effects, including immunotoxicity. Echinacea purpurea is an important medicinal plant with immunostimulatory and anti-inflammatory activities. We have investigated the protective effect of an herbal formulation (Immulant) containing E. purpurea extract against cisplatin-induced immunotoxicity in rats. METHODS Forty mature albino rats were randomized into four groups (10 rats/group). Control (group 1) animals were subjected to intraperitoneal (i.p.) injection of saline solution (0.2 ml) once every 3 days. Group 2 animals received cisplatin (3.5 mg/kg, i.p.) once every 3 days for successive 2 weeks. Group 3 rats received oral Immulant (150 mg/kg) once daily for 2 weeks. Group 4 animals received oral Immulant treatment as in group 3 in addition to cisplatin as in group 2. Serum level of total protein and albumin, total and differential leukocytic count, phagocytic activity of monocytes, humoral activity and splenic histopathology and immunohistochemistry were used as diagnostic markers of immunotoxicity. RESULTS Cisplatin induced marked inhibition of cellular immunity as exhibited by significant decrease of leukocytic count, lymphocyte percentage and phagocytic activity with marked increase in neutrophil percentage. Humoral immunity represented by marked inhibition in total protein and γ-globulin concentration and significant inhibition in antibody titer against Mycoplasma gallisepticum were recorded. Histopathological and immunohistochemical observation of the spleen of cisplatin-treated rats revealed obvious pathological findings of marked depletion and degeneration of lymphoid tissue. Co-oral administration of Immulant resulted in substantial improvement of various immunotoxicological indices compared to cisplatin control. CONCLUSION The herbal medicine Immulant is an immunostimulant which could be used to treat the immunotoxic effects of cisplatin. Graphical abstract Cisplatin (CP) is a highly effective antineoplastic DNA alkylating agent. CP induces free radical production causing an oxidative damage.Cisplatin induced marked inhibition in cellular and humoral immunityEchinacea purpurea (Immulant) is a powerful anticytotoxic agent against cisplatin toxicity.

Abstract
OBJECTIVE Assessing adverse drug reactions (ADRs) is a proven method to estimate the safety of medicines. The ADRs to herbal medicines in Australia (and by inference, the safety of herbal medicines in Australia) remain unknown. This study examines spontaneous ADR cases to four of the most popular herbs in Australia from 2000 to 2015: echinacea (Echinacea purpurea), valerian (Valeriana officinalis), black cohosh (Actaea racemosa) and ginkgo (Ginkgo biloba). METHODS ADRs of echinacea, valerian, black cohosh and ginkgo reported to the Australian Therapeutic Goods Administration (TGA) between 2000 and 2015 were obtained from the TGA database. Data were collated and analysed according to age, sex, severity, type of ADR and body system affected. Statistics were calculated using GraphPad Prism software. RESULTS Most ADRs were mild or moderate. However, every herbal medicine was associated with life-threatening ADRs. In each life-threatening case, the herbal medicine was taken concomitantly with prescription medications. Black cohosh was associated with a significant number of severe ADRs (30.3% of the total), with 39.4% of these ADRs being associated with abnormal hepatic function, hepatitis or hepatotoxicity. CONCLUSION This study highlights the lack of public awareness with regard to herb-drug interactions, since most of the severe ADRs involved a herb-drug interaction.

Abstract
The differences in volatile profile of Echinacea purpurea plants not-inoculated (EpC) and inoculated with their endophytes from roots (EpR) and stem/leaves (EpS/L) were analysed and compared by GC-FID/GC-MS in an in vitro model. Non-terpenes and sesquiterpene hydrocarbons were the most abundant classes with an opposite behaviour of EpS/L showing a decreased emission of sesquiterpenes and an increase of non-terpene derivatives. The main compounds obtained from EpS/L were (Z)-8-dodecen-1-ol and 1-pentadecene, while germacrene D and β-caryophyllene were the key compounds in EpC and EpR. For the first time, this work indicates that bacterial endophytes modify the aroma profiles of infected and non-infected in vitro plants of the important medicinal plant E. purpurea. Therefore, our model of infection could permit to select endophytic strains to use as biotechnological tool in the production of medicinal plants enriched in volatile bioactive compounds.

Abstract
In this study, the influence of the dietary incorporation of Echinacea purpurea (EP) extract and/or vitamin C on the intestinal histomorphology and some immunological indices were tested in the Nile tilapia (Oreochromis niloticus Linn.). O. niloticus were randomly divided into four groups. The control group G1 was fed on a basal diet, while the G2 and G3 were fed on basal diets, supplemented with EP extract and vitamin C at the doses of 500 mg kg-1 and 400 mg kg-1, respectively. Meanwhile, G4 was fed on a basal diet, supplemented with a mixture of EP extract and vitamin C. After 28 days of feeding, the intestinal tissues were collected for histological observation and immune status, was based on an assay for measuring the phagocytic activity. Furthermore, the expression of the transforming growth factor-beta 1 (TGF-β1), interleukin-1beta (IL-1β), and tumor necrosis factor alpha (TNF-α) genes was evaluated in intestine and head kidney. The results revealed that the G4 successfully surpassed the other groups in terms of the heights of intestinal villi, the number of goblet cells and intraepithelial lymphocytes (IELs), and the phagocytic activity, followed by the G3 and G2. The expression of the IL-1β and TNF-α genes were up regulated only in G4 but in the G3 only the expression of the IL-1β gene was up regulated. Hence, EP extract along with vitamin C could be used as a feed additive in order to improve the structure of the intestinal mucosal epithelium and immune response in tilapia.

Abstract
The genus Echinacea consists of 11 taxa of herbaceous and perennial flowering plants. In particular, Echinacea purpurea (L.) Moench is widely cultivated all over the United States, Canada, and in Europe, exclusively in Germany, for its beauty and reported medicinal properties. Echinacea extracts have been used traditionally as wound healing to improve the immune system and to treat respiratory symptoms caused by bacterial infections. Echinacea extracts have demonstrated antioxidant and antimicrobial activities, and to be safe. This survey aims at reviewing the medicinal properties of Echinacea species, their cultivation, chemical composition, and the potential uses of these plants as antioxidant and antibacterial agents in foods and in a clinical context. Moreover, the factors affecting the chemical composition of Echinacea spp. are also covered.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Native Americans used plants from the genus Echinacea to treat a variety of different inflammatory conditions including swollen gums, sore throats, skin inflammation, and gastrointestinal disorders. Today, various Echinacea spp. preparations are used primarily to treat upper respiratory infections. AIM OF THE STUDY The goal of this study was to evaluate the effects of an ethanolic E. purpurea (L) Moench root extract and the alkylamide dodeca-2E,4E-dienoic acid isobutylamide (A15) on mast cells, which are important mediators of allergic and inflammatory responses. Inhibition of mast cell activation may help explain the traditional use of Echinacea. MATERIALS AND METHODS A15 was evaluated for its effects on degranulation, calcium influx, cytokine and lipid mediator production using bone marrow derived mast cells (BMMCs) and the transformed rat basophilic leukemia mast cell line RBL-2H3. Methods included enzymatic assays, fluorimetry, ELISAs, and microscopy. A root extract of E. purpurea, and low and high alkylamide-containing fractions prepared from this extract, were also tested for effects on mast cell function. Finally, we tested A15 for effects on calcium responses in RAW 264.7 macrophage and Jurkat T cell lines. RESULTS A15 inhibited ß-hexosaminidase release from BMMCs and RBL-2H3 cells after treatment with the calcium ionophore A23187 by 83.5% and 48.4% at 100µM, respectively. Inhibition also occurred following stimulation with IgE anti-DNP/DNP-HSA. In addition, A15 inhibited 47% of histamine release from A23187-treated RBL-2H3 cells. A15 prevented the rapid rise in intracellular calcium following FcεRI crosslinking and A23187 treatment suggesting it acts on the signals controlling granule release. An E. purpurea root extract and a fraction with high alkylamide content derived from this extract also displayed these activities while fractions with little to no detectable amounts of alkylamide did not. A15 mediated inhibition of calcium influx was not limited to mast cells as A23187-stimulated calcium influx was blocked in both RAW 264.7 and Jurkat cell lines with 60.2% and 43.6% inhibition at 1min post-stimulation, respectively. A15 also inhibited the release of TNF-α, and PGE2 to a lesser degree, following A23187 stimulation indicating its broad activity on mast cell mediator production. CONCLUSIONS These findings suggest that Echinacea extracts and alkylamides may be useful for treating allergic and inflammatory responses mediated by mast cells. More broadly, since calcium is a critical second messenger, the inhibitory effects of alkylamides on calcium uptake would be predicted to dampen a variety of pathological responses, suggesting new uses for this plant and its constituents.

Abstract
The World Health Organization has approved magnetic nanoparticles (MNP) for use as a contrast agent for magnetic resonance imaging or tumor hyperthermia treatment. MNP are toxic over time after intra-testicular injection. A clear strategy to ameliorate the toxic side effects of MNP in normal tissues after medical application has not yet been developed. We used an extract of Echinacea purpurea (EP) as a natural source of antioxidant and free radical scavenging product for detoxification of MNP in testicular tissues. MNP localization in the interstitial area of testicular tissue reduced the expression of insulin-like factor 3 (INSL3) proteins as well as serum testosterone levels. Further, MNP caused accumulation of both collagen and elastin in the interstitial area and increased the thickness of the tunica albuginea. Injection of MNP during administration of EP extract for short periods slightly reduced the toxic side effects of MNP. After extended exposure to EP extract, INSL3 expression and testosterone returned to near control levels. Also, collagen and elastin accumulation caused by MNP was reduced after extended exposure to EP extract. We believe that the ameliorative effect of EP extract is due to its antioxidant properties.

Abstract
Echinacea purpurea has been widely used for the prevention and treatment of upper respiratory tract infections and the common cold. The restraint stress has been reported to suppress a broad spectrum of immune functions. The aim of this study was to investigate the protective effects of the pressed juice of E. purpurea (L.) Moench (EFLA®894; Echinacea) against restraint stress-induced immunosuppression in BALB/c mice. Echinacea significantly normalized the restraint stress-induced reduction in splenocyte proliferation and splenic natural killer (NK) cell activity (P < .05). Echinacea treatment significantly increased the percentages of CD4+ and CD8+ T lymphocytes in the blood (P < .05). In addition, Echinacea restored serum cytokine levels, including interleukin-6 (IL-6), interleukin-10 (IL-10), and interleukin-17 (IL-17), as well as the mRNA expressions of these cytokines in spleen (P < .05). Our findings suggest that Echinacea might have beneficial effects on restraint stress-induced immunosuppression by increasing splenocyte proliferation and NK cell activity, while modulating T lymphocyte subsets and cytokine levels in the blood.

Abstract
A rapid and sensitive Ultra High Performance Liquid Chromatography Electrospray Ionization Tandem Mass Spectrometry (UHPLC-ESI-MS/MS) method was developed and validated to simultaneously determine the concentration of seven phenolic acids (syringic acid, ferulic acid, caffeic acid, vanillic acid, p-coumaric acid, 3,4-dihydroxybenzoic acid and 4-hydroxybenzoic acid) in rat plasma after oral administration of Echinacea purpurea extract. After mixing with the internal standard (IS), butylparaben, plasma samples were prepared by liquid–liquid extraction with ethyl acetate. The separation was performed using the Agilent Eclipse Plus C18 column (1.8 μm, 2.1 mm × 50 mm) with a gradient system consisting of solution A (0.1% acetic acid in water) and solution B (methanol) at a flow rate of 0.3 mL/min. The detection was accomplished by a multiple reaction monitoring (MRM) mode with electrospray ionization (ESI). The method was validated in terms of linearity, precision, accuracy, extraction recovery, matrix effect and stability. This method was successfully applied to study the pharmacokinetic properties of the seven compounds after oral administration of Echinacea purpurea extract in rats.

Abstract
In this study, we investigated the immunomodulatory effects of a supplemented killed influenza virus (V) by Echinacea purpurea (E) and Nigella sativa (N) extracts and effect of changing the route of immunization from intramuscular (IM) to intraperitoneal (IP). At the 2nd-, 3rd- and 4th-week post-IM immunizations (WPIMI), the supplemented V with N (VN) induced the most significant IgM response unlike N alone. At the 2nd WPIMI, V or VN induced the highest significant IgG levels. At the 2nd-week post-IP immunization (WPIPI), E and VN induced the most significant IgG levels. Both at the 3rd and 4th WPIMI or WPIPI, various treatments induced significant increases in IgG. At the 4th WPIMI, E, V, and V with E (VE) induced significant increases in the CD4+ thymocytes while all IP treatments caused significant increase in their counts. V and VN induced the most significant IM induction of CD8+ thymocytes while their best IP stimulation was induced by N, VE, and VN. At the 4th WPIMI, various treatments caused significant increases in the mesenteric lymph node (MLN) CD4+, CD8+ counts. WPIPI with V or VE caused significant increases in both the CD4+- and CD8+ MLN cells, whereas VN significantly induced CD8+ MLN cells only. WPIPI with various treatments caused significant increases in the B-cell counts and the peak was obtained by VN.

Abstract
BACKGROUND Atopic eczema (AE) is a chronic inflammatory and pruritic skin disease. There is still an unmet need for topical anti-inflammatory and anti-pruritic substances exhibiting an excellent safety profile. The endocannabinoid system is known to regulate various aspects of cutaneous barrier and immune functions, thus targeting it may be a valid approach for alleviating the symptoms of AE. OBJECTIVE To assess the putative efficacy of Echinacea purpurea-derived alkylamides (Ec. extract) activating cannabinoid (CB)-2 receptors in exerting anti-inflammatory effects and alleviating symptoms of AE. METHODS In vitro anti-inflammatory efficiency was investigated by monitoring the effects of Ec. extract on poly-(I:C)-induced pro-inflammatory cytokine expression (Q-PCR) and release (ELISA) of HaCaT keratinocytes. Irritancy and sensitization potential (assessed by Human Repeat Insult Patch Test; Clinical trial 1); clinical efficiency in alleviating symptoms of AE (Clinical trial 2) as well as effects on human skin structure and lipid content (Clinical trial 3 followed by transmission electron microscopy and HPTLC) were investigated in randomized double blind clinical trials. RESULTS Ec. extract significantly reduced mRNA expression as well as release of poly-(I:C)-induced pro-inflammatory cytokines (IL-6 and IL-8) in keratinocytes. Thus, not surprisingly, the well-tolerated (Clinical trial 1) Ec. extract-based cream reduced local SCORAD statistically significantly, not only compared to baseline, but also compared to the comparator (Clinical trial 2). Of great importance, besides the in vitro anti-inflammatory effects, administration of the Ec. extract-based cream also resulted in significantly higher levels of overall epidermal lipids, ceramide EOS (ω-esterified fatty acid+sphingosine sphingoid base), and cholesterol at Day 15 compared to baseline as well as significantly greater numbers of intercellular lipid lamellae in the intercellular space (Clinical trial 3). CONCLUSION The investigated Ec. extract shows great potential in alleviating cutaneous symptoms of AE, and by exerting remarkable anti-inflammatory actions and restoring the epidermal lipid barrier, it will be very likely a well-tolerated, powerful novel ingredient for the adjuvant therapy of AE.

Abstract
Echinacea (Echinacea purpurea), green tea (Camellia sinensis) and yaylacayi (Thymus praecox OPIZ subsp. grossheimii (Ronniger) Jalas) are herbs used in traditional medicine because of their beneficial health effects. A high performance liquid chromatography (HPLC) post-column method was developed by coupling HPLC with on-line antioxidant assays using diode array (DAD) and ultraviolet (UV) detectors. Thus antioxidant compounds and fifteen phenolic standards were detected in echinacea, green tea and yaylacayi methanol extracts simultaneously. Later on, the developed on-line HPLC coupled system was used to compare three different antioxidant methods, ABTS [2,2'-Azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid)], DPPH (2,2-diphenyl-1-picrylhydrazyl and FRAP (Ferric reducing antioxidant power). Eight compounds with antioxidant activity were identified as gallic acid, protocatechuic aldehyde, p-OH benzoic acid, chlorogenic acid, caffeic acid, vanillin, ferulic acid, and rosmarinic acid. For validation purposes, LOD (limit of detection) (0.36-14.68μg/mL) and LOQ (limit of quantification) (1.35-48.92μg/mL) values were calculated for six standards. The results showed that while the post-column ABTS and FRAP assays were repeatable, sensitive and supportive of each other, the post-column DPPH assay did not provide reliable results. Also due to the base-line noise and drifts in post-column DPPH assay, identification and quantitation of analytes could not be done accurately.

Abstract
Echinacea is used ethnomedicinally for the treatment of various diseases such as cough, respiratory infections, and bronchitis among other uses in Eastern Cape region of South Africa. This study evaluated the volatile components of the essential oil of the plant, its toxicity, anti-inflammatory and analgesic activities in rodents. Dried leaf and root of the plant were separately processed by hydrodistillation for 4 h and their essential oils (EOs) were collected. Extracted oils were subjected to GC/GC-MS analysis. The essential oil was further evaluated for acute toxicity, anti-inflammatory and analgesic activities. The toxicity profile of the essential oil was evaluated in mice through the oral route (p.o.), and anti-inflammatory activity was evaluated on the carrageenan-induced edema model in rats at the doses of 100-200 mg/kg, while its analgesic effect was evaluated on the acetic acid-induced writhings model in mice at doses of 100-200 mg/kg. GC/GC-MS analysis of EOs showed that a number of compounds identified in the leaf and root oils were 25 and 31 respectively. The chemical compositions of the oils varied and the major compounds identified in the oils include germacrene D, naphthalene, caryophyllene oxide, α-phellandrene and α-cadinol. The essential root oil did not cause mortality at the highest dose of 5000 mg/kg; hence, its LD50 was estimated to be ⩾5000 mg/kg, p.o. The anti-inflammatory test results showed that the essential root oil caused significant (p < 0.05-0.01) reduction in edema size compared to the negative control group on the carrageenan-induced edema and the results for the analgesic test showed that the essential root oil caused significant (p < 0.05) reduction in number of writhings at 1000 mg/kg compared to the negative control group. It is concluded that root and leaf of this Echinacea species contain volatile oils which varied in their yield and chemical compositions. The essential root oil is non-toxic orally and it demonstrated significant anti-inflammatory and analgesic activities in laboratory animals.

Abstract
The extraction yield, total phenols, caffeic acid derivatives (CAD), and antioxidant properties of 50% ethanolic Echinacea purpurea flower extract were determined. The in vitro inhibitory effects of 50% ethanolic extract and CAD on α-amylase, α-glucosidase, and angiotensin-converting enzyme (ACE) linked with type 2 diabetes were also investigated. The extraction yield, total phenols, and total CAD of the extract were 27.04%, 195.69 mg CAE/g and 78.42 mg/g, respectively. Cichoric acid (56.03 mg/g) was the predominant CAD compound in the extract. The extract exhibited good antioxidant properties. The extract and CAD inhibited α-amylase, α-glucosidase, and ACE activities in a concentration-dependent manner. Among the tested samples, chlorogenic acid, and caffeic acid (IC50 of 1.71-1.81 mg/mL) had the highest α-amylase inhibitory activity, cichoric acid (IC50 of 0.28 mg/mL) showed higher α-glucosidase inhibitory activity. Both chlorogenic acid and caffeic acid (IC50 of 0.11-0.14 mg/mL) demonstrated higher ACE-inhibitory activity. The in vitro results suggest that E. purpurea extract and CAD have good potential for managing hyperglycemia and hypertension. Overall, the data suggest it is a choice for developing antihyperglycemia and antihypertension compounds from field-grown E. purpurea.

Abstract
Nowadays green synthesis of metal nanoparticles is a developing area of research. In this study, titanium dioxide nanoparticles were biosynthesized using an aqueous solution of Echinacea purpurea herba extract as a bioreductant. This is novel and interesting method for synthesis of TiO2 nanoparticles. The prepared titanium dioxide nanoparticles were characterized using ultraviolet-visible spectroscopy (UV-VIS), transmission electron microscopy (SEM), total reflection X-Ray fluorescence analysis (TXRF) and Fourier-transform infrared spectroscopy (FTIR). The size of TiO2 nanoparticles was found to be in the range of 120 nm. Moreover, the alkaline reaction of the solution (pH = 8) resulted in the increase in absorbance (280 nm), which facilitates the growth of the number of TiO2 nanoparticles in the studied solution. Also, synthesis of TiO2 nanoparticles using green resources like Echinacea purpurea herba is a better alternative to chemical synthesis, since this green synthesis is pollutant-free and eco-friendly.

Abstract
CONTEXT Progressive resistance of Leishmania parasite to available drugs including, meglumine antimoniate, has been reported from various regions of the world, especially Iran. AIMS This study was conducted to evaluate the effect of hydroalcoholic extract of Echinacea purpurea in a combination therapy with glucantime in the treatment of cutaneous leishmaniasis caused by Leishmania major. MATERIALS AND METHODS Hydroalcoholic extract of E. purpurea was prepared from the plant. Amastigote form of L. major was inoculated to the tail base of thirty mice. After their tails became wounded, mice were divided into six groups. The first group was used as control and the second group received 100 mg/kg of Echinacea extract (orally). The third group was treated by meglumine antimoniate with dose of 20 mg/kg. Combination therapy was used for group four, five, and six where the mice received a different concentration of extract (100-200 mg/kg) and glucantime (10-20 mg/kg). The size of the cutaneous lesion on tail base was measured regularly. Findings were analyzed by SPSS software and using Kruskal-Wallis test. RESULTS The sizes of the lesion were increased in all mice of control group by the time. The mean size of lesions in mice receiving the extract and/or receiving the extract along with meglumine antimoniate was lower than those of control mice, but the differences were not statistically significant (P > 0.05). On the other hand, the differences between the group of mice which received meglumine antimoniate alone, and the rest of groups were statistically significant (P < 0.05). CONCLUSION E. purpurea extract in doses which have been used in this study and combination with meglumine antimoniate was not much effective against L. major in BALB/C mice.

Abstract
Burkholderia cepacia complex bacteria (Bcc) represent a serious threat for immune-compromised patient affected by Cystic Fibrosis (CF) since they are resistant to many substances and to most antibiotics. For this reason, the research of new natural compounds able to inhibit the growth of Bcc strains has raised new interest during the last years. A source of such natural compounds is represented by medicinal plants and, in particular, by bacterial communities associated with these plants able to produce molecules with antimicrobial activity. In this work, a panel of 151 (endophytic) bacteria isolated from three different compartments (rhizospheric soil, roots, and stem/leaves) of the medicinal plant Echinacea purpurea were tested (using the cross-streak method) for their ability to inhibit the growth of 10 Bcc strains. Data obtained revealed that bacteria isolated from the roots of E. purpurea are the most active in the inhibition of Bcc strains, followed by bacteria isolated from the rhizospheric soil, and endophytes from stem/leaf compartment. At the same time, Bcc strains of environmental origin showed a higher resistance toward inhibition than the Bcc strains with clinical (i.e. CF patients) origin. Differences in the inhibition activity of E. purpurea-associated bacteria are mainly linked to the environment -the plant compartment- rather than to their taxonomical position.

Abstract
The growth of fish is directly dependent on feed composition and quality. Medicinal plants can be added to fish feed as adjuvant therapy for the prevention of fish diseases. The purple coneflower (Echinacea purpurea (L.) Moench.) has been reported to have multiple biological effects, including immunomodulatory and antioxidant activity. The most active compounds of E. purpurea are polyphenols - caffeic acid derivatives: caftaric acid, chlorogenic acid, cynarin, echinacoside and cichoric acid. Due to a relatively limited number of studies on the use of the purple coneflower as a nutritional supplement for fish feeding, extruded fish feed with addition of Echinacea roots was produced. In the feed total phenolic content, selected polyphenol contents, the energetic value, nutrient contents and antioxidant capacity were examined. The results indicate that fish feed with addition of the Echinacea has a great potential to be a good source of natural radical scavengers, for example polyphenols, and nutritive ingredients. Antioxidant properties of feed were well correlated with the coneflower content. The study findings confirmed that high-temperature extrusion-cooking process does not deactivate phenolic antioxidant compounds, which are present both in the Echinacea roots and in the final product. Fish feed with addition of E. purpurea can be used as a nutritional supplement in the prevention of fish diseases caused by oxidative stress.

Abstract
In this work we analyzed the composition and structure of cultivable bacterial communities isolated from the stem/leaf and root compartments of two medicinal plants, Echinacea purpurea (L.) Moench and Echinacea angustifolia (DC.) Hell, grown in the same soil, as well as the bacterial community from their rhizospheric soils. Molecular PCR-based techniques were applied to cultivable bacteria isolated from the three compartments of the two plants. The results showed that the two plants and their respective compartments were characterized by different communities, indicating a low degree of strain sharing and a strong selective pressure within plant tissues. Pseudomonas was the most highly represented genus, together with Actinobacteria and Bacillus spp. The presence of distinct bacterial communities in different plant species and among compartments of the same plant species could account for the differences in the medicinal properties of the two plants.

Abstract
Echinacea purpurea-containing remedies are herbal medicines used in respiratory tract infections and several inflammatory conditions as enhancers of non-specific and modulators of specific cellular immunity. They also exert anti-inflammatory, anti-viral, and anti-microbial activity. The aim of the present study was to compare the in vivo influence of orally administered three Echinacea purpurea-based remedies (IMMUNAL drops, ECHINACEA FORTE drops, IMMUNAL FORTE tablets) on some parameters of cellular and humoral immunity in mice.

Abstract
Botanical extracts of Echinacea purpurea have been widely used for the treatment of upper respiratory infections. We sought to chemically examine fungal endophytes inhabiting E. purpurea, and to identify compounds produced by these endophytes with in vitro cytokine-suppressive activity. Twelve isolates from surface sterilized seeds of E. purpurea were subjected to fractionation and major components were isolated. Sixteen secondary metabolites belonging to different structural classes were identified from these isolates based on NMR and mass spectrometry data. The compounds were tested for their influence on cytokine secretion by murine macrophage-type cells. Alternariol (1), O-prenylporriolide (4), porritoxin (10) β-zearalenol (13), and (S)-zearalenone (14) inhibited production of TNF-α from RAW 264.7 macrophages stimulated with LPS in the absence of any significant cytotoxicity. This is the first report of a cytokine-suppressive effect for 4. The results of this study are particularly interesting given that they show the presence of compounds with cytokine-suppressive activity in endophytes from a botanical used to treat inflammation. Future investigations into the role of fungal endophytes in the biological activity of E. purpurea dietary supplements may be warranted.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Echinacea purpurea (L.) Moench is one of the mostly used herbs in the traditional medicine for the treatment of respiratory diseases. Modern interest in Echinacea is directed to its immunomodulatory activity. Recent studies have shown that secretion of asthma-related cytokines in the bronchial epithelial cells can be reversed by Echinacea preparations. AIM OF THE STUDY To examine the pharmacodynamics profile of Echinacea active principles, a complex has been isolated from its flowers by alkaline extraction and has been tested using an animal model of allergic asthma. MATERIAL AND METHODS The structural features of Echinacea purpurea complex was determined using chemical and spectroscopic methods. Allergic inflammation of the airways was induced by repetitive exposure of guinea pigs to ovalbumin. Echinacea complex was then administered 14 days in 50mg/kg b.w. daily dose perorally. Bronchodilatory effect was verified as decrease in the specific airway resistance (sRaw) in vivo and by reduced contraction amplitude (mN) of tracheal and pulmonary smooth muscle to cumulative concentrations of acetylcholine and histamine in vitro. The impact on mucociliary clearance evaluated measurement of ciliary beat frequency (CBF) in vitro using LabVIEW™ Software. Anti-inflammatory effect of Echinacea complex was verified by changes in exhaled NO levels and by Bio-Plex® assay of Th2 cytokine concentrations (IL-4, IL-5, IL-13 and TNF-alpha) in serum and bronchoalveolar lavage fluid (BALF). RESULTS Chemical and spectroscopic studies confirmed the presence of carbohydrates, phenolic compounds and proteins, as well as the dominance of rhamnogalacturonan and arabinogalactan moieties in Echinacea complex. The significant decrease in sRaw values and suppressed histamine and acetylcholine-induced contractile amplitude of isolated airways smooth muscle that were similar to effects of control drug salbutamol confirmed Echinacea complex bronchodilatory activity. The anti-inflammatory effect was comparable with that of control agent budesonide and was verified as significantly reduced exhaled NO levels and concentration of Th2 cytokines in serum and BALF. The values of CBF were changed only insignificantly on long-term administration of Echinacea complex suggested its minimal negative impact on mucociliary clearance. CONCLUSION Pharmacodynamic studies have confirmed significant bronchodilatory and anti-inflammatory effects of Echinacea complex that was similar to effects of classic synthetic drugs. Thus, results provide a scientific basis for the application of this herb in traditional medicine as a supplementary treatment of allergic disorders of the airways, such as asthma.
