Dăescu AM, Nistor M, Nicolescu A, Pop R, Bunea A, Rugina D, Pintea A. Antioxidant, Enzyme Inhibitory, and Protective Effect of Amelanchier lamarckii Extract. PLANTS (BASEL, SWITZERLAND) 2024; 13:1347. [PMID: 38794418 PMCID: PMC11125170 DOI: 10.3390/plants13101347] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Revised: 05/04/2024] [Accepted: 05/08/2024] [Indexed: 05/26/2024]
Abstract
The present study aimed to investigate the chemical content of Romanian juneberries (Amelanchier lamarckii), their effect on antioxidant and enzyme inhibition activities, and their bioaccessibility after simulated in-vitro digestion. In Amelanchier lamarckii extract (AME), 16 polyphenolic compounds were identified by LC-ESI+-MS analysis. The most representative compounds found in the extract were cyanidin-galactoside, 3,4-dihydroxy-5-methoxybenzoic acid, feruloylquinic acid, and kaempferol, all belonging to the anthocyanins, phenolic acids, and flavonols subclasses. The polyphenols of AME exert quenching abilities of harmful reactive oxygen species, as the CUPRAC antioxidant assay value was 323.99 µmol Trolox/g fruit (FW), whereas the FRAP antioxidant value was 4.10 μmol Fe2+/g fruit (FW). Enzyme inhibition assays targeting tyrosinase (IC50 = 8.843 mg/mL), α-glucosidase (IC50 = 14.03 mg/mL), and acetylcholinesterase (IC50 = 49.55 mg/mL) were used for a screening of AME's inhibitory potential against these key enzymes as a common approach for the discovery of potential antidiabetic, skin pigmentation, and neurodegenerative effects. The screening for the potential antidiabetic effects due to the α-glucosidase inhibition was performed in glucose-induced disease conditions in a human retinal pigmented epithelial cell experimental model, proving that AME could have protective potential. In conclusion, AME is a valuable source of phenolic compounds with promising antioxidant potential and metabolic disease-protective effects, warranting further investigation for its use in the nutraceutical and health industries.

Abd El-Ghany WA. Potential Effects of Garlic ( Allium sativum L.) on the Performance, Immunity, Gut Health, Anti-Oxidant Status, Blood Parameters, and Intestinal Microbiota of Poultry: An Updated Comprehensive Review. Animals (Basel) 2024; 14:498. [PMID: 38338142 PMCID: PMC10854602 DOI: 10.3390/ani14030498] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 01/20/2024] [Accepted: 01/22/2024] [Indexed: 02/12/2024] Open
Abstract
The use of antibiotics as growth promoters or for the prevention of some poultry diseases has faced global concern and serious criticism. Their addition to poultry feed has shown hazardous effects, including the development of antimicrobial resistance and a potentially harmful effect on human health. To eliminate these threats, there is increasing interest in natural alternatives. Plant derivatives such as garlic (Allium sativum L.) and its derivatives are presently extensively used in the poultry production system. The dietary supplementation of broilers and layers with garlic induced improvement in the production parameters, carcass quality, and intestinal integrity. The modulation of the immune response against some important viral diseases has resulted from the supplementation of poultry with garlic. Moreover, garlic has been shown to modulate gut health through antibacterial and antiparasitic activities. Treatment with garlic can also mitigate oxidative stress and reduce free-radical production. The reduction of cholesterol levels and improvement of some liver and blood parameters were also reported following the dietary inoculation of garlic. This review was designed to investigate the influence of garlic as a dietary additive on the performance, immunity, gut health, anti-oxidant status, blood parameters, and intestinal microbiota of poultry.

Abstract
Tamarindus indica L., is widely used tree in ayurvedic medicine. Here, we aimed to understand the presence of important constituents in seeds and peel of Tamarind fruits and their biological activities. Hence, seeds and peel of Tamarind fruits are used for further extraction process by soxhlet method (chloroform and ethyl acetate solvents). Results suggest that the ethyl acetate extract (seeds) consists of terpenoids (72.29 ± 0.513 mg/g), phenolic content (68.67 ± 2.11 mg/g) and flavonoids (26.36 ± 2.03 mg/g) whereas chloroform extract (seeds) has terpenoids (42.29 ± 0.98 mg/g). Similarly, chloroform extract (peel) has terpenoids (25.96 ± 3.20 mg/g) and flavonoids (46.36 ± 2.03 mg/g) whereas ethyl acetate extract (peel) has terpenoids (62.93 ± 0.987 mg/g). Furthermore, anti-inflammation activity results revealed that the chloroform extract of peel was found to be more effective with IC50 of 226.14 µg/ml by protein denaturation analysis and with IC50 of 245.5 µg/ml on lipoxygenase inhibition activity. Chloroform extract (peel and seeds) shown better antioxidant activity using DPPH than ethyl acetate extract (peel and seeds). Ethyl acetate extract of seeds showed impressive potency by inhibiting the growth of fungus, Candida albicans. Additionally, ethyl acetate extract of seeds showed impressive potency inhibiting the growth of Escherichia coli than Bacillus cereus. GC-MS analysis shown the existence of diverse set of phytochemicals in each extract. Overall, comparative studies highlight the effectiveness of seeds extracts than peel extracts. Moreover, GC-MS results suggest that the seeds and peel extracts (chloroform and ethyl acetate) contains a wide range of compounds (including flavonoids, isovanillic acid, fatty acids and phenolic compounds) which can be utilized for therapeutic purpose.

Abstract
Gouty arthritis is one of the most common metabolic disorders affecting people. Plant based drugs can lower the risk of this health disorder. The anti-gouty potential of Eucalyptus torquata flowers methanol extract (ETME) was evaluated in vitro via measuring the inhibitory effects of five pro-inflammatory enzymes; xanthine oxidase (XO), hyaluronidase, lipoxygenase (5-LOX), cyclooxygenases COX-1, and COX-2, in addition to evaluating the inhibition of histamine release, albumin denaturation, membrane stabilization, tyrosinase, and protease inhibitory activities. Also, its antioxidant potential was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging assays and ferric reducing power assay (FRAP). HPLC-PDA-MS/MS was used to identify the metabolites in the tested extract. The latter exhibited substantial anti-arthritic properties in all assays with comparable potential to the corresponding reference drugs. HPLC-MS/MS analysis of this bioactive extract tentatively annotated 46 metabolites including phloroglucinols, gallic and ellagic acids derivatives, terpenes, flavonoids, fatty acids, and miscellaneous metabolites. Our study highlights the medicinal importance of E. torquata as an anti-gouty candidate and opens new avenues of gouty management.

Effects of garlic and lemon essential oils on performance, digestibility, plasma metabolite, and intestinal health in broilers under environmental heat stress. BMC Vet Res 2022; 18:430. [PMID: 36503512 PMCID: PMC9743731 DOI: 10.1186/s12917-022-03530-y] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2022] [Accepted: 11/24/2022] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Natural feed additives play an important role in poultry production due to their safety and potential properties as an antioxidant and antimicrobial, as well as a growth stimulant. The present research was designed to assess the influence of dietary supplementation of either garlic, lemon essential oil, or their mixture on performance, nutrient digestibility, plasma constituents, immunity, and oxidative status, as well as intestinal development assessed by microbiota-histomorphology development in broilers under environmental heat stress. METHODS A total of 480 broiler chicks (Ross 308) at one-day-old were randomly divided into four groups (120 chicks/ group). The control group received the basal diet (CON), while the other three groups received the basal diet supplemented with 200 mg/kg garlic essential oil (GEO), 200 mg/kg lemon essential oil (LEO), and their mixture (GLO) 200 mg/kg diet, respectively for 35 days. RESULTS The obtained results revealed that broilers fed essential oils as a mixture or individually had an improvement in average body weight, feed conversion ratio, carcass dressing, and an increase in digestive enzymes activities compared to the control group, furthermore, there was a reduction in the mortality rate and abdominal fat content. Adding essential oils as a mixture or individually led to a decrease in (P < 0.05) blood plasma triglycerides, cholesterol, low-density lipoprotein, and an increase in high-density lipoprotein. Broilers fed diets supplemented with essential oils as a mixture or individually had higher values of superoxide dismutase and glutathione peroxidase; while plasma malondialdehyde was lower (P < 0.05) compared to the control diet. Moreover, there was a significant enhancement in intestinal microbial content, and intestinal histological status of chickens fed with essential oils. CONCLUSIONS Conclusively, including the mixture of essential oils improved performance, nutrient digestibility, and digestive enzymes activities. It also enhanced immunity, antioxidant state, and lipid profile, and gut microbiota- histomorphology in broilers. It was proposed that the broilers diet be supplemented with a mixture of essential oils to a mitigation of the effects of heat stress.

Abstract
The edible and medicinal plants (EMPs) are becoming an abundant source for cancer prevention and treatment since the natural and healthy trend for modern human beings. Currently, there are more than one hundred species of EMPs widely used and listed by the national health commission of China, and most of them indicate immune or metabolic regulation potential in cancer treatment with numerous studies over the past two decades. In the present review, we focused on the metabolic influence in immunocytes and tumor microenvironment, including immune response, immunosuppressive factors and cancer cells, discussing the immunometabolic potential of EMPs in cancer treatment. There are more than five hundred references collected and analyzed through retrieving pharmacological studies deposited in PubMed by medical subject headings and the corresponding names derived from pharmacopoeia of China as a sole criterion. Finally, the immunometabolism modulation of EMPs was sketch out implying an immunometabolic control in cancer treatment.

Abstract
In this study, a polydopamine (PDA)-modified hollow fiber-immobilized xanthine oxidase (XOD) was prepared for screening potential XOD inhibitors from flavonoids. Several parameters for the preparation of PDA-modified hollow fiber-immobilized XOD, including the dopamine concentration, modification time, XOD concentration and immobilization time, were optimized. The results show that the optimal conditions for immobilized XOD activity were a dopamine concentration of 2.0 mg/mL in 10.0 mM Tris-HCl buffer (pH 8.5), a modification time of 3.0 h, an XOD concentration of 1000 μg/mL in 10.0 mM phosphate buffer (pH 7.5) and an immobilization time of 3.0 h. Subsequently, the enzymatic reaction conditions such as the pH value and temperature were investigated, and the enzyme kinetics and inhibition parameters were determined. The results indicate that the optimal pH value (7.5) and temperature (37 °C) of the PDA-modified hollow fiber-immobilized XOD were consistent with the free enzyme. Moreover, the PDA-modified hollow fiber-immobilized XOD could still maintain above 50% of its initial immobilized enzyme activity after seven consecutive cycles. The Michaelis–Menten constant (Km) and the half-maximal inhibitory concentration (IC50) of allopurinol on the immobilized XOD were determined as 0.25 mM and 23.2 μM, respectively. Furthermore, the PDA-modified hollow fiber-immobilized XOD was successfully applied to evaluate the inhibitory activity of eight flavonoids. Quercetin, apigenin, puerarin and epigallocatechin showed a good inhibition effect, and their percentages of inhibition were (79.86 ± 3.50)%, (80.98 ± 0.64)%, (61.15 ± 6.26)% and (54.92 ± 0.41)%, respectively. Finally, molecular docking analysis further verified that these four active compounds could bind to the amino acid residues in the XOD active site. In summary, the PDA-modified hollow fiber-immobilized XOD is an efficient method for the primary screening of XOD inhibitors from natural products.

Abstract
Elastase and tyrosinase are important targets both for cosmetics and for dermatological disorders. In this work, ninety herbal products were tested as inhibitors of these two enzymes. Eleven extracts resulted strongly active. Four out of them (Camellia sinensis, Ginkgo biloba, Rhodiola rosea, Vitis vinifera) inhibited both enzymes, five (Glycyrrhiza glabra, Ribes nigrum, Rheum officinale, Salvia officinalis, Tilia platyphyllos) were active against tyrosinase only, and two (Ceterach officinarum and Cinnamomum zeylanicum) proved selectively active against elastase. The IC50 ranged from 3.1 to 104.9 μg/mL and 19.3 to 164.3 μg/mL, against elastase and tyrosinase, respectively. The most active extracts resulted enriched in flavonoids (from 1.47 to 56.47 mg RE/g of extract) and phenolics (from 37.43 to 123.56 mg GAE/g of extract), indicating also an antioxidant potential. Finally, a positive correlation between enzymatic bioactivities and phenolic content was also established.

Abstract
Natural products may be applied in a wide range of domains, from agriculture to food and pharmaceutical industries. In this study, the antioxidant properties and the capacity to inhibit some enzymatic activities of Euphorbia resinifera and Euphorbia officinarum aqueous extracts and honeys were assessed. The physicochemical characteristics were also evaluated. Higher amounts of iron, copper and aluminium were detected in E. officinarum honey, which may indicate environmental pollution around the beehives or inadequate storage of honey samples. This honey sample showed higher amounts of total phenols and better capacity for scavenging superoxide anion free radicals and DPPH free radicals as compared with E. resinifera honey, but poorer capacity for inhibiting lipoxygenase, acetylcholinesterase, tyrosinase and xanthine oxidase. The ratio plant mass:solvent volume (1:100) and extraction time (1 - 2 h) were associated with higher total phenols and better antioxidant activities and lipoxygenase, acetylcholinesterase and tyrosinase inhibitory activities, regardless of the plant species. The aqueous extracts had systematically higher in vitro activities than the respective honey samples.

Abstract
This study aimed to compare the effect of fermentation and drying on the organoleptic characteristic, total phenolic content, antioxidant and anti-inflammatory activities of Peperomia pellucida (L.) Kunth tea with commercial Camellia sinensis tea. The phenolic content, antioxidant and anti-inflammatory activities in P. pellucida were significantly (p < 0.05) lower than C. sinensis, irrespective of the fermentation and drying methods. Although fermentation decreased the total phenolics, flavonoids and antioxidant activity in both P. pellucida and C. sinensis teas, the anti-inflammatory potential of P. pellucida was significantly (p < 0.05) improved. Principle component analysis revealed that fermentation and drying methods contributed to respective 42.3% and 27.2% of activity variation in P. pellucida. The browning index was positively correlated with fermentation index (r = 0.670, p < 0.05) of leaves samples. Overall, unfermented and fermented P. pellucida leaves were best dried with microwaving and freeze drying, respectively for optimal antioxidant and anti-inflammatory activities with favorable consumer's acceptance.

Abstract
The white beetroot cv. Śnieżna Kula is the first betanin-free beetroot registered in the European Union. The aim of this study was to compare the phenolic acids profile and antioxidant capacity of leaves of white (SK) and red (CC) beetroots and red (LC) and white (BL) Swiss chard growing in Poland. LC leaves were the richest source of total phenolics (16.55 mg GAE/g FW) and phenolic acids (1.81 mg/g FW), while the highest content of flavonoids was determined in CC leaves (1.6 mg QE/g FW). The highest antiradical activity was observed for LC, whereas CC extract exhibited the highest chelating power. BL and CC leaf extracts demonstrated high LOX inhibitory potential (EC50 = 53.23 and 56.97 mg FW/mL, respectively). An uncompetitive type of LOX inhibition was obtained for all extracts. SK extracts demonstrated the highest XO inhibitory activity (EC50 = 81.04 mg FW/mL). A noncompetitive type of XO inhibition was obtained in both extracts from red leaves (CC and LC), whereas an uncompetitive mode of inhibition was observed in the case of white leaf (SK and LC) extracts. Thus, it can be assumed that the presence of betanin influences the XO inhibition mechanism.

Abstract
Xanthine oxidase (XOD) is a key enzyme in the human body to produce uric acid, and its inhibitor can be used for the treatment of hyperuricemia and gout. In this study, an online CE-based XOD immobilized enzyme microreactor (IMER) was developed for the enzyme kinetics assays and inhibitor screening. After 30 consecutive runs, the XOD activity remained about 95.6% of the initial immobilized activity. The Michaelis-Menten constant (Km ) of the immobilized XOD was determined as 0.39 mM using xanthine as substrate. The half-maximal inhibitory concentration and inhibition constant of the known inhibitor 4-aminopyrazolo[3,4-d]pyrimidine on XOD were determined as 11.9 and 5.2 μM, respectively. Then, the developed method was applied to evaluate the XOD inhibitory activity of 10 flavonoids, which indicated that dihydroquercetin, quercetin, biochanin A, and epicatechin had significant inhibitory effect on XOD. In addition, molecular docking results verified that the binding energy of the flavonoids with enzyme were in line with their inhibitory activity determined by XOD-IMER. Therefore, the developed XOD-IMER is a potential tool for the primary screening of XOD inhibitors from natural products.

Abstract
Human carbonic anhydrase isozyme II has been used as protein target for disorder treatment including glaucoma. Current clinically used sulfonamide-based CA inhibitors can induce side effects, and so alternatives are required. This study aimed to investigate a natural CA inhibitor from Murraya paniculata. The previously developed yeast-based assay was used to screen 14 compounds isolated from M. paniculata and identified by NMR analysis for anti-human CA isozyme II (hCAII) activity. Cytotoxicity of the compounds was also tested using the same yeast-based assay but in a different cultivation condition. Two flavonoid candidate compounds, 5, 6, 7, 8, 3', 4', 5'-heptamethoxyflavone (4) and 3 ,5, 7, 8, 3', 4', 5'-heptamethoxyflavone (9), showed potent inhibitory activity against hCAII with a minimal effective concentration of 10.8 and 21.5 μM, respectively, while they both exhibited no cytotoxic effect even at the highest concentration tested (170 μM). The results from an in vitro esterase assay of the two candidates confirmed their hCAII inhibitory activity with IC50 values of 24.0 and 34.3 μM, respectively. To investigate the potential inhibition mechanism of compound 4, in silico molecular docking was performed using the FlexX and Swissdock software. This revealed that compound 4 coordinated with the Zn2+ ion in the hCAII active site through its methoxy oxygen at a distance of 1.60 Å (FlexX) or 2.29 Å (Swissdock). The interaction energy of compound 4 with hCAII was -13.36 kcal/mol. Thus, compound 4 is a potent novel flavonoid-based hCAII inhibitor and may be useful for further anti-CAII design and development.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In northwestern Argentina inhabit several ancient indigenous communities with diverse cultural and historical background. Geographical isolation has contributed to the prevalence of a native plant-based folk medicine; "jarilla" species are medicinal plants widely used in local communities for the treatment of mycosis, respiratory, gastrointestinal and rheumatic disorders. THE AIM OF THE STUDY To assemble the traditional knowledge acquired through years with scientific data concerning to phytochemistry, antioxidant and anti-inflammatory potential of three "jarillas" species. MATERIAL AND METHODS Ethnobotanical data of three "jarillas", Zuccagnia punctata (Zp), Larrea cuneifolia (Lc), and Larrea divaricata (Ld), were explored by interviewing native people from Indigenous Community of Amaicha del Valle, Tucumán. Phenolic profiles from each infusion were analyzed by HPLC-ESI-MS/MS. Antioxidant activity was determined by superoxide anion and hydrogen peroxide scavenging capacity, lipoperoxidation inhibition, and ferrous iron chelating activity. It was also assessed their ability to inhibit pro-inflammatory enzymes, such as xanthine oxidase, lipoxygenase, and hyaluronidase. RESULTS Ethnobotanical interviews showed that local people use "jarillas" mainly as infusions and baths. It was reported different categories of uses, such as medicinal (10 curative applications), to religious purposes, tinctorial, as construction material and as fuel. From infusions prepared, the MS and MS/MS data allowed the identification of 27 compounds from Z. punctata, and 11 from both Larrea sp. The infusions showed an important antioxidant activity through different mechanisms, highlighting Zp and Lc in free radical scavenging capacity and Ld on lipid peroxidation inhibition and iron binding. They were also capable of inhibit xanthine oxidase and lipoxygenase enzymes, being Lc the most active one. CONCLUSIONS This research work provides novel information concerning to several categories of traditional uses of "jarilla" species in a Diaguita-Calchaquí community and focus attention to infusions from a phytochemical and biological approach.

Abstract
An in vitro study was conducted to evaluate the effects of thidiazuron (TDZ) growth regulator and magnesium oxide (MgO) nanoparticles on radish (Raphanus sativus L.) under lead (Pb) stress. Effects of TDZ and MgO on seed germination, growth, biomass, total phenolics and flavonoids, antioxidant potential, and Pb phytoaccumulation in different plant parts were assessed. Nanoparticles of MgO were synthesized with leaf extract of Sageretia thea (Osbeck) plant. Thidiazuron and MgO nanoparticles were added to growth media in individual and in combinations. Lead (50 mg L-1) was added to growth media. Thidiazuron and MgO nanoparticles increased plant growth, phenolic and flavonoid contents, free radical scavenging activity, and lead phytoaccumulation. The increase was highly significant in TDZ and MgO nanoparticle combination treatments (T5, T6). Treatment (T6) showed a sixfold increase in Pb accumulation (1721.73 ± 17.4 μg g-1 dry biomass) as compared to control (274.29 ± 4.23 μg-1g-1). Total phenolic and dry biomass showed significantly positive correlation in leaves (R2 = 0.73), stem (R2 = 0.58), and roots (R2 = 0.72). The correlation of Pb accumulation and phenolic contents was significantly positive in root (R2 = 0.80), stem (R2 = 0.92), and leaves (R2 = 0.69). Flavonoid showed a positive correlation with dry biomass and Pb accumulation. Antioxidant activity was highly increased in leaves followed by stem and root. Findings show that TDZ in combination with MgO nanoparticles can play a significant role in secondary metabolite production and Pb phytoaccumulation.

Abstract
This work aimed to characterize compositional and bioactive features of Aloe vera leaf (fillet, mucilage, and rind) and flower. The edible fillet was analysed for its nutritional value, and all samples were studied for phenolic composition and antioxidant, anti-inflammatory, antimicrobial, tyrosinase inhibition, and cytotoxic activities. Dietary fibre (mainly mannan) and available carbohydrates (mainly free glucose and fructose) were abundant macronutrients in fillet, which also contained high amounts of malic acid (5.75 g/100 g dw) and α-tocopherol (4.8 mg/100 g dw). The leaf samples presented similar phenolic profiles, with predominance of chromones and anthrones, and the highest contents were found in mucilage (131 mg/g) and rind (105 mg/g) extracts, which also revealed interesting antioxidant properties. On the other hand, the flower extract was rich in apigenin glycoside derivatives (4.48 mg/g), effective against Pseudomonas aeruginosa (MIC = 0.025 mg/mL and MBC = 0.05 mg/mL) and capable of inhibiting the tyrosinase activity (IC50 = 4.85 mg/mL). The fillet, rind, and flower extracts also showed a powerful antifungal activity against Aspergillus flavus, A. niger, Penicillium funiculosum, and Candida albicans, higher than that of ketoconazole. Thus, the studied Aloe vera samples displayed high potential to be exploited by the food or cosmetic industries, among others.

Abstract
The present study aimed, on the one hand, to improve the yield of microwave assisted extraction (MAE) of polyphenols from beech bark by using a design of experiments (DoE) approach. On the other hand, beech bark extracts (BBE) were characterized in terms of their phytochemical profile and evaluated for biological potential (antioxidant, antibacterial, antifungal, antimutagen, anti-α-glucosidase, and anti-tyrosinase). The extraction time varies with the amount of extracted total phenolic content (TPC). The microwave power favors TPC extraction but in different proportions. The optimum conditions which gave the highest TPC (76.57 mg GAE/g dry plant material) were reached when the microwave power was 300 W, extraction time was 4 min, and the solvent was an ethanol–water (50:50) mixture. The practical value of TPC after a controlled experiment was 76.49 mg GAE/g plant material. The identified compounds were vanillic acid, gallic acid, epicatechin, catechin, protocatechuic acid, chlorogenic acid, ferulic acid, and isoquercitrin. The antioxidant potential of BBEs was demonstrated by in vitro experiments. The BBEs were active against Staphylococcus aureus, Pseudomonas aeruginosa, Salmonella typhimurium, Escherichia coli, and Candida species. All extracts were antimutagenic and expressed an inhibition on α-glucosidase and tyrosinase activity. Regarding antimutagen activity, the assayed extracts may be considered to have low or no antimutagen effects.

Essential Oil and Ethanol Extract of Oregano (Origanum vulgare L.) from Armenian Flora as a Natural Source of Terpenes, Flavonoids and other Phytochemicals with Antiradical, Antioxidant, Metal Chelating, Tyrosinase Inhibitory and Antibacterial Activity. Curr Pharm Des 2019; 25:1809-1816. [DOI: 10.2174/1381612825666190702095612] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2019] [Accepted: 06/20/2019] [Indexed: 11/22/2022]
Abstract
Background:
Origanum vulgare is used in Armenian cuisine as well as in folk medicine. The aim of
this investigation was to determine the peculiarities of the chemical composition of Armenian flora’s oregano
essential oil (EO) and ethanol extract (EE) and to characterize mainly antioxidant and antibacterial properties in
vitro.
Methods:
EO of plant aerial parts was extracted by the hydro-distillation method, and the composition was analyzed
by gas-chromatography (GC). EE was prepared using ethanol as a solvent. Antioxidant, antibacterial and
other biological activity of EO and EE was determined using appropriate methods.
Results:
The terpenes were found to be the greatest part of oregano EO (β-caryophyllene epoxide - 13.3 %; β-
caryophyllene -8.2 %; ο-cymene - 5.2 %). The flavonoid content of EE was 3.9±0.7 mg g-1 catechin equivalents.
Antiradical activities of EO and EE expressed with half-maximum inhibitory concentrations were 1057 µg mL-1
and 19.97 µg mL-1. The antioxidant index in the case of using extract (1000 µg mL-1) was 77.3±1.5 %. The metal
chelating activity of EE was 74.5±0.2 %. The tyrosinase inhibitory activities of EO, EE and arbutin were 26.5±0.3
%, 6.5±0.2 % and 50±0.1 %, respectively. Both EO and EE of oregano were able to suppress the growth of testmicroorganisms
including clinical pathogen isolates, but have moderate antimicrobial activity. EO antibacterial
activity against ampicillin-resistant Escherichia coli was similar to the activity against non-resistant strain. EE
was not active against ampicillin-resistant E. coli in contrast to non-resistant one.
Conclusion:
The results indicate high antioxidant and moderate antibacterial as well as high antiradical, metal
chelating, tyrosinase inhibitory activity of oregano EO and EE, which can be used as a natural source of terpenes,
flavonoids and other phytochemicals in medicine, pharmaceutics, cosmetics and food industry. EO has antibacterial
activity also against ampicillin-resistant E. coli.

Impact of Interactions between Ferulic and Chlorogenic Acids on Enzymatic and Non-Enzymatic Lipids Oxidation: An Example of Bread Enriched with Green Coffee Flour. APPLIED SCIENCES-BASEL 2019.

Abstract
This study investigated the activity, mode of inhibition, and interactions between lipoxygenase (LOX) inhibitors and compounds able to inhibit lipids oxidation (LPO) derived from green coffee beans (GCBs), wholemeal wheat flour (WF), and bread enriched with GCB, in comparison with pure chemical standards of the main active components—ferulic (FA) and chlorogenic acids (CGA). Both GCB and WF contain potentially bioaccessible and bioavailable LPO inhibitors acting synergistically. Both FA and CGA presented nearly additive interaction. Potentially bioaccessible LOX inhibitors from GCB and WF acted synergistically, whereas moderate antagonism was found for potentially bioavailable compounds. The activity of CGA and FA was quite similar (EC50 = 18.56 and 22.36 g DW/ml, respectively) and synergistic action between these components was found. The LPO activity of functional breads was positively correlated with the percentage of GCB (R2 = 0.98). Ferulic acid and CGA acted as competitive LOX inhibitors, whereas potentially bioaccessible compounds from bread enriched with GCB demonstrated an uncompetitive mode of action. Green coffee beans, WF, and the proposed functional product could be helpful in dietary therapy and prevention of so-called lifestyle disorders related with the lipid metabolism. Moreover, this paper highlights the need to study the interactions between the active ingredients of newly designed functional products.

Abstract
In the present work two Galatella species, Galatella villosa Rchb.f. and Galatella tatarica (Less.) Novopokr collected from Kazakhstan were subjected to hydrodistillation to yield essential oils (EOs), and to maceration in methanol to yield extracts (MEs). The EOs and MEs were evaluated for antioxidant and in vitro inhibitory activities against α-amylase, tyrosinase, lipoxygenase and xanthine oxidase enzymes. The EOs of G. villosa and G. tatarica were investigated for chemical composition using GC-FID and GC/MS techniques. The composition of MEs was investigated with LC-MS/MS technique. Monoterpenes, β-pinene (23.6 %) and α-pinene (14.4 %) were the main constituents of G. tatarica essential oil, while the oil of G. villosa was characterized not only with monoterpene α-pinene (9.0 %), but also fatty acid, hexadecanoic acid (10.2%). 3-, 5-, 1,5- and 3,4-caffeoylquinic acids, 3-, 4- and 5-feruloylquinic acids, quercetin and its different glycosides were detected in MEs according to mass spectral data. G. tatarica (IC50=74.3 μg/mL) and G. villosa (IC50=78.5 μg/mL) extracts showed significant antioxidant activity. In the β-carotene bleaching test, the extracts demonstrated noteworthy activity (%Inh 44.46 and 41.14). The extracts scavenged ABTS radical as 1.85 mM and 1.27 mM of Trolox. In a concentration of 0.5 mg/mL, the oils showed 89% and 85% inhibition of α-amylase, while the extracts showed 86% and 78% inhibition at 2 mg/mL concentration, respectively. The EOs demonstrated noteworthy potent LOX enzyme inhibition ranging between 45% and 57%. In xanthine-xanthine oxidase model system, the extracts demonstrated the highest inhibitory potency ranging between 43% and 39%. The present work is the first contribution to the chemistry and biological activities of G. tatarica and G. villosa.

Abstract
In this short review, the current knowledge on the botany, ecology, uses, and medicinal properties of the multipurpose Garcinia subelliptica (Fukugi) is updated. As yet, there are no reviews on this indigenous and heritage coastal tree species of the Ryukyu Islands in Japan, which has ethnocultural, ecological, and pharmacological significance. Planted by the Okinawan people some 300 years ago, Fukugi trees serve as windbreaks and accord protection against the destructive typhoons. The species has become a popular ornamental tree, and its bark has been used for dyeing fabrics. It forms part of the food chain for mammals and insects and serves as nesting sites for birds. Endowed with bioactive compounds of benzophenones, xanthones, biflavonoids, and triterpenoids, G. subelliptica possesses anticancer, anti-inflammatory, anti-tyrosinase, trypanocidal, antibacterial, DNA topoisomerase inhibitory, DNA strand scission, choline acetyltransferase enhancing, hypoxia-inducible factor-1 inhibitory, and antiandrogenic activities. Fukugetin and fukugiside are two novel biflavonoids named after the species. The chemical constituents of Fukugi fruits when compared with those of mangosteen yielded interesting contrasts.

Abstract
The synthesis of 14-(aryl)-14H-naphto[2,1-b]pyrano[3,2-e][1,2,4]triazolo[1,5-c]pyrimidine-2-yl) acetamidoximes 2a-e has been accomplished by reaction of 2-acetonitrile derivatives 1a-e with hydroxylamine. Cyclocondensation reaction of precursors 2a-e with some elctrophilic species such as ethylorthoformate, acetic anhydride, and methyl-acetoacetate provided the new oxadiazole derivatives 3a-e, 4a-e, and 5a-e, respectively. On the other hand, the reaction of precursors 2a-e with 2-chloropropanoyl chloride afforded the new acetimidamides 6a-e which evolve under reflux of toluene to the new oxadiazoles 7a-e. The synthetic compounds were screened for their anti-xanthine oxidase, anti-soybean lipoxygenase, and cytotoxic activities. Moderate to weak xanthine oxidase and soybean lipoxygenase inhibitions were obtained but significant cytotoxic activities were noted. The most cytotoxic activities were recorded mainly (i) 5a was the most active (IC50 = 4.0 μM) and selective against MCF-7 and (ii) 2a was cytotoxic against the four cell lines with selectivity for MCF-7 and OVCAR-3 (IC50 = 17 and 12 μM, respectively) while 2e is highly selective against OVCAR-3 (IC50 = 10 μM).

Abstract
Most of the present anticancer drugs are highly cytotoxic and focus mainly on killing tumor cells rather than slowing the progress of cancer metastasis. Evidence has been reported that bridges the mechanisms of inflammation and tumor invasion. Therefore, we evaluated the potency in cancer metastasis chemoprevention of compounds and a coumarin extracted from Murraya exotica, which is known for its anti-inflammation bioactivity. By carrying out experiments in vitro, we found the root extracts more efficient than the leaf extracts in restraining cell migration of MDA-MB-231 cells, while leaf extracts presented slightly stronger inhibition of tumor cell adhesion at low concentrations. In addition, compared to root extracts, a novel coumarin identified previously from root extracts showed equal inhibition on cancer cell adhesion and less inhibition on cell migration. All extracts used in this study presented low cytotoxicity in vitro. Through comparison of the contents of leaf and root extracts from M exotica, several compounds are considered promising against cancer metastasis. This study evaluates the worth of further development of M exotica to find its effect on cancer metastasis chemoprevention.

Abstract
Autophagy is a self-destructive process that degrades cytoplasmic constituents. In our previous study, Koelreuteria formosana ethanolic extract (KFEE), which is obtained from natural plants endemic to Taiwan, has inhibited cell metastasis in renal carcinoma cells. However, the anticancer effects of KFEE on colon cancer remain unclear. In this study, KFEE exerted a strong cytotoxic effect on DLD-1 and COLO 205 human colorectal cancer cell lines. KFEE effectively inhibited cancer cell proliferation, induced G2/M-phase arrest associated with downregulaton of cyclin E, cyclin B and cdc25C and upregulation of p21, and induced cell death by activating autophagy but did not cause apoptotic cell death. Exposed KFEE cells showed increased levels of acridine orange, autophagic vacuoles, and LC3-II proteins, which are specific autophagic markers. Bcl-2, p-Akt, and p-mTOR levels, which have been implicated in autophagic downregulation, were decreased after KFEE treatment. Autophagy inhibitor 3-methyladenosine and bafilomycin-A1 and genetic silencing of LC3 attenuated KFEE-induced growth inhibition. These findings suggested that KFEE causes cytostatic effect through autophagy. In xenograft studies, oral administration of KFEE had significantly inhibited the tumor growth in nude mice that had received subcutaneous injection of DLD-1 cells. KFEE is a promising candidate in phytochemical-based, mechanistic, and pathway-targeted cancer prevention strategies.

Abstract
Context The antioxidative properties of plants or plant derivative products are well known for their free radical scavenging effects. Flagellaria indica L. (Flagellariaceae) (FI) is a tropical medicinal plant used by the natives of Sabah as medication for semi-paralysis. Objective This study evaluates the hepatoprotective mechanism of FI against carbon tetrachloride (CCl4)-mediated liver damage. Materials and methods Aqueous extract of FI leaves was orally administered to adult Sprague-Dawley rats once daily for 14 consecutive days at 300, 400, and 500 mg/kg b.w. prior to CCl4 treatment (1.0 mL/kg b.w.) on the 13th and 14th days. Results Total phenolic content in the aqueous extract of FI leaves was 65.88 ± 1.84 mg gallic acid equivalent/g. IC50 value for free radical scavenging activity of FI aqueous extract was reached at the concentration of 400 μg/mL. Biochemical studies show that the aqueous extract of FI was able to prevent the increase in levels of serum transaminases, alanine aminotransferase, and aspartate aminotransferase (38-74% recovery), and malondialdehyde formation (25-87% recovery) in a dose-dependent manner. Immunohistochemical results evidenced the suppression of oxidative stress markers (4-hydroxynonenal and 8-hydroxydeoxyguanosine) and pro-inflammatory markers (tumour necrosis factor-α, interleukin-6, prostaglandin E2). Histopathological and hepatocyte ultrastructural alterations proved that there were protective effects in FI against CCl4-mediated liver injury. Signs of toxicity were not present in rats treated with FI alone (500 mg/kg b.w.). Discussion and conclusion It can be concluded that the presence of phenolic constituents and their antioxidative effects can be credited to the hepatoprotective activity of FI.

Abstract
Fagonia indica, a very important anticancer plant, has been less explored for its in vitro potential. This is the first report on thidiazuron (TDZ)-mediated callogenesis and elicitation of commercially important phenolic compounds. Among the five different plant growth regulators tested, TDZ induced comparatively higher fresh biomass, 51.0 g/100 mL and 40.50 g/100 mL for stem and leaf explants, respectively, after 6 weeks of culture time. Maximum total phenolic content (202.8 μg gallic acid equivalent [GAE]/mL for stem-derived callus and 161.3 μg GAE/mL for leaf-derived callus) and total flavonoid content (191.03 μg quercetin equivalent [QE]/mL for stem-derived callus and 164.83 μg QE/mL for leaf-derived callus) were observed in the optimized callus cultures. The high-performance liquid chromatography (HPLC) data indicated higher amounts of commercially important anticancer secondary metabolites such as gallic acid (125.10 ± 5.01 μg/mL), myricetin (32.5 ± 2.05 μg/mL), caffeic acid (12.5 ± 0.52 μg/mL), catechin (9.4 ± 1.2 μg/mL), and apigenin (3.8 ± 0.45 μg/mL). Owing to the greater phenolic content, a better 2-2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging activity (69.45 % for stem explant and 63.68 % for leaf explant) was observed in optimized calluses. The unusually higher biomass and the enhanced amount of phenolic compounds as a result of lower amounts of TDZ highlight the importance of this multipotent hormone as elicitor in callus cultures of F. indica.

Abstract
Rhodiola rosea (Rro) has been reported to have various pharmacological properties, including anti-fatigue, anti-stress and anti-inflammatory activity. It is also known to improve glucose and lipid metabolism, but the effects of Rhodiola rosea on adipocyte differentiation and metabolism are not still elucidated. In this study the anti-adipogenic and lipolytic activity of two extracts of Rhodiola rosea, containing 3% salidroside (RS) or 1% salidroside and 3% rosavines (RR) on primary human visceral adipocytes was investigated. Pre-adipocytes were analyzed after 10 and 20 days of treatment during differentiation and after 7 days of treatment when they reached mature shape. The RS extract significantly induced higher apoptosis and lipolysis in comparison to control cells and to RR extract. In contrast, RR extract significantly reduced triglyceride incorporation during maturation. Differentiation of pre-adipocytes in the presence of RS and RR extracts showed a significant decrease in expression of genes involved in adipocyte function such as SLC2A4 and the adipogenic factor FGF2 and significant increase in expression of genes involved in inhibition of adipogenesis, such as GATA3, WNT3A, WNT10B. Furthermore RR extract, in contrast to RS, significantly down-regulates PPARG, the master regulator of adipogenesis and FABP4. These data support the lipolytic and anti-adipogenetic activity of two different commercial extracts of Rhodiola rosea in primary human visceral pre-adipocytes during differentiation.

Abstract
This study is an attempt to evaluate the hepatoprotective activity of Tabernaemontana divaricata against DEN and Fe NTA induced liver necrosis in rats. Ethanolic extract of the whole plant of Tabernaemontana divaricata at doses of 200 and 400 mg/kg body weight and 5-fluorouracil (standard drug) was orally administered to male Wistar Albino rats once daily for 24 weeks, simultaneously treated with the carcinogen DEN and Fe NTA. In simultaneously treated animals, the plant extract significantly decreased the levels of uric acid, bilirubin, AST, ALT, and ALP in serum and increased the levels of liver marker enzymes in liver. Treatment with the extracts resulted in a significant increase in the levels of antioxidants accompanied by a marked reduction in the levels of malondialdehyde when compared to DEN and Fe NTA treated group. When compared with 200 mg/kg bw rats, 400 mg/kg bw rats and 5-fluorouracil treated rats showed better results in all the parameters. The histopathological studies confirmed the protective effects of extract against DEN and Fe NTA induced liver necrosis. Thus, it could be concluded that the use of Tabernaemontana divaricata extract in the treatment of carcinogen induced hepatic necrosis.

Abstract
Using a fractionation technique, four phytochemicals were isolated from Rhodiola crenulata extracts. These compounds were identified as 4'-hydroxyacetophenone (4-HAP), epicatechin-(4β,8)-epicatechin gallate (B2-3'-O-gallate), salidroside, and p-tyrosol using mass spectrometry and nuclear magnetic resonance spectroscopy. The inhibition of xanthine oxidase (XO) activity by these purified compounds was then evaluated and compared to that of a known XO inhibitor (allopurinol; IC50 = 12.21 ± 0.27 μM). Both 4-HAP and B2-3'-O-gallate showed an XO inhibitory effect, for which the half maximal inhibitory concentration (IC50) values were 15.62 ± 1.19 and 24.24 ± 1.80 μM, respectively. However, salidroside and p-tyrosol did not show significant inhibitory effects on XO at 30 μM. Furthermore, an inhibition kinetics study indicated that 4-HAP and B2-3'-O-gallate are mixed competitive inhibitors. The inhibition constants (Ki) of 4-HAP and B2-3'-O-gallate were 8.41 ± 1.03 and 6.16 ± 1.56 μM, respectively. These results suggest that 4-HAP and B2-3'-O-gallate are potent XO inhibitors.

Abstract
The aim of this study was to investigate and to compare the extractability, bioaccessibility, and bioavailability in vitro of antioxidative compounds from bark of selected Salix species: S. alba (SA), S. daphnoides (SD), S. purpurea (SP), and S. daphnoides x purpurea (SDP) hybrid willow clones originating from their natural habitats and cultivated on the sandy soil. The highest amount of phenolic glycosides was found in the bark of SDP and SD. The best source of phenolics was bark of SDP. The highest content of flavonoids were found in SD bark samples, whereas the highest concentration of bioaccessible and bioavailable phenolic acids was determined in SDP bark. Bark of all tested Salix species showed significant antiradical activity. This properties are strongly dependent on extraction system and genetic factors. Regardless of Salix genotypes, the lowest chelating power was found for chemically-extractable compounds. Bark of all Salix species contained ethanol-extractable compounds with reducing ability. Besides this, high bioaccessibility and bioavailability in vitro of Salix bark phytochemicals were found. Obtained results indicate that extracts from bark tested Salix genotypes can provide health promoting benefits to the consumers; however, this problem requires further study.

Abstract
We investigated the effects of an aqueous alcohol extract of Rhodiola rosea (R. rosea) and its hydrolysate on melanin synthesis and the mechanisms mediating the activity. The ratio of tyrosol to salidroside was 2.3 in hydroalcoholic extract, and 51.0 in hydrolysate. We found that R. rosea extract and its hydrolysate inhibited melanin synthesis and tyrosinase activity in mouse melanoma cells (B16F0 cells). R. rosea extract also inhibited gene and protein expression of melanocortin 1 receptor (MC1R) and inhibited c-AMP response element binding protein (CREB) phosphorylation, suppressed the activation of AKT and glycogen synthase kinase-3 beta (GSK3β), and inhibited the expression of microphthalmia-associated transcription factor (MITF) and tyrosinase-related protein 1 (TRP-1). R. rosea hydrolysate inhibited the phosphorylation of CREB, the activation of AKT and GSK3β, and the expression of MITF and tyrosinase. Our results suggest that R. rosea extract is a novel tyrosinase inhibitor and that it exerts its effects by regulating the CREB/MITF/tyrosinase pathway in B16F0. Further in vivo studies are needed to determine the effectiveness of R. rosea extract as a skin whitening agent.

Abstract
Abstract Pulmonary hypertension (PH) is a chronic, complex, and progressive disease that eventuates in fatality. Research efforts over the past decades have resulted in therapeutic options that improve quality of life and prolong survival of patients, but they do not offer a cure. We propose a philosophical model that a disturbed balance of yin and yang results in pulmonary vascular remodeling, the hallmark of PH pathology. The model may be useful in exploring the wisdom of traditional Chinese medicine and incorporating it into mainstream PH research. In this context, the medicinal plant Rhodiola can be of profound interest owing to its variety of health-friendly attributes. Rhodiola has been shown to be beneficial in high-altitude-related symptoms and acute exacerbation of PH; moreover, improvement of PH has been demonstrated experimentally in chronically hypoxic rats. The beneficial effects of Rhodiola in PH may be attributable to its potential targeting of the signaling pathways, such as endothelin-1, nitric oxide, vascular endothelial growth factor, angiotensin-converting enzyme, nuclear factor κ-B, tumor necrosis factor α, and interleukin-6. Alterations in these mediators are implicated in PH pathogenesis, the characteristics of which include chronic pulmonary vasoconstriction, vasoproliferation, and vascular inflammation. Salidroside, one of the compounds extracted from Rhodiola, has been found to provide therapeutic benefits in experimental PH. As the data are limited and the field is in its infancy, further studies including in-depth analysis of the therapeutic effects on various animal models of PH are desirable. We believe that future PH research should place an adequate and special emphasis on exploring and promoting the potential of traditional Chinese medicine, and to this end, the medicinal plant Rhodiola offers a promising field on which to embark.

Tyrosinase inhibitory effect and antioxidative activities of fermented and ethanol extracts of Rhodiola rosea and Lonicera japonica. ScientificWorldJournal 2013; 2013:612739. [PMID: 24307875 PMCID: PMC3836399 DOI: 10.1155/2013/612739] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2013] [Accepted: 09/25/2013] [Indexed: 12/03/2022] Open
Abstract
This is the first study to investigate the biological activities of fermented extracts of Rhodiola rosea L. (Crassulaceae) and Lonicera japonica Thunb. (Caprifoliaceae). Alcaligenes piechaudii CC-ESB2 fermented and ethanol extracts of Rhodiola rosea and Lonicera japonica were prepared and the antioxidative activities of different concentrations of samples were evaluated using in vitro antioxidative assays. Tyrosinase inhibition was determined by using the dopachrome method with L-DOPA as substrate. The results demonstrated that inhibitory effects (ED50 values) on mushroom tyrosinase of fermented Rhodiola rosea, fermented Lonicera japonica, ethanol extract of Lonicera japonica, and ethanol extract of Rhodiola rosea were 0.78, 4.07, 6.93, and >10 mg/ml, respectively. The DPPH scavenging effects of fermented Rhodiola rosea (ED50 = 0.073 mg/ml) and fermented Lonicera japonica (ED50 = 0.207 mg/ml) were stronger than effects of their respective ethanol extracts. Furthermore, the scavenging effect increases with the presence of high content of total phenol. However, the superoxide scavenging effects of fermented Rhodiola rosea was less than effects of fermented Lonicera japonica. The results indicated that fermentation of Rhodiola rosea and Lonicera japonica can be considered as an effective biochemical process for application in food, drug, and cosmetics.
