Farfarae Flos Mitigates Cigarette Smoking-Induced Lung Inflammation by Regulating the Lysophosphatidylcholine Biosynthesis and Tryptophan Metabolism

An increased risk of developing respiratory diseases has been linked to exposure to cigarette smoking (CS). The flower buds of Tussilago farfara L., also known as Farfarae Flos (FF), can be used for the treatment of cough, bronchitis, and asthmatic disorders in China. In the present study, we used lung and fecal metabolomics, as well as the intestinal flora analysis, aimed to investigate the protective effect of FF against the CS exposure induced lung inflammation on mice. The results showed that FF administration could relieve the lung inflammation as demonstrated by lung index, interleukin-6 (IL-6), and interleukin-1β (IL-1β) levels, as well as the pulmonary pathological change. The lung metabolomics coupled with molecular docking showed that FF could alleviate lung inflammation by regulating lysophosphatidylcholine biosynthesis through the caffeoyl quinic acids distributed in the lung tissue. In addition, fecal metabolome coupled with 16S rRNA gene sequencing showed that FF could regulate the tryptophan metabolism by regulating the intestinal flora disorders. This study provided new insights of FF to relieve CS-induced pulmonary inflammation with the multimechanism.

Prunella vulgaris and Tussilago farfara demonstrate anti-inflammatory activity in rabbits and protect human adipose stem cells against thermal stress in vitro

ETHNOPHARMACOLOGICAL RELEVANCE

Prunella vulgaris L.(PV) and Tussilago farfara (TF) are perennial herbs rich in flavonoids and phenolic compounds with immense medicinal value. PV extract (PV-E) possesses potent antipyretic, anti-inflammtory, antioxidant, antiseptic, anti-cancer and immune stimulatory properties and have been traditionally known for the treatment of wounds, ulcers and sores. TF extract (TF-E) has been known for antibacterial, antioxidant, anti-inflammatory, anti-viral, anti-diabetic, anti-cancer, anti-obesity and wound healing effects. Additionally, TF-E infusions have been used for asthma, cough, and bronchopneumonia treatments.

AIM OF THE STUDY

The therapeutic efficacy of transplanted human adipose stem cells (hASCs) is abrogated under the deteriorating effects of heat stress offered by burn wounds. Earlier researches has documented antioxidant priming as an effective strategy to enhance stem cell performance. As both PV-E and TF-E are known for their potent antioxidant effects. The present study aims to examine the cryoprotective effects of PV-E and TF-E priming on hASCs against in-vitro heat-induced thermal stress. Moreover, we determined the anti-inflammatory potential of both PV-E and TF-E on rabbits.

METHODS

Antioxidant capacity of both PV-E and TF-E is examined via DPPH assay and anti-inflammatory activity is assessed in rabbits using carrageen-induced paw edema model of inflammation. Next, we investigate the efficacy of different doses (1.25-100 μg/ml) of PV-E and TF-E on hASCs; MTT, LDH, calcein AM staining, and wound scratch assay were used to assess cell viability, cytotoxicity, proliferation ability and cell migration potential in the cells. Then, hASCs were pretreated for 24 h with optimum doses of PV-E and TF-E determined from MTT assay results and were subsequently exposed to in-vitro thermal injury (51 °C,10 min). The cytoprotective effects of both PV-E and TF-E priming under thermal stress were investigated via MTT, LDH, annexin-V staining and gene expression analysis.

RESULTS

Both PV-E and TF-E extracts demonstrated potent antioxidant and effective anti-inflammatory activities, with a clear reduction in inflammation. Study on hASCs exhibited improved cell viabilities, enhanced cell proliferation and migration abilities of both extracts. While heat stress data revealed that PV-E (2.5 μg/ml) and TF-E (5 μg/ml) pretreatment significantly ameliorated effects of thermal-injuries in hASCs as depicted by significantly enhanced cell viabilities, low LDH release profile, and lower annexin-V expression and regulated gene expression of the pretreated cells.

CONCLUSION

PV-E and TF-E priming effectively enabled hASCs to combat thermal injury by significantly promoting cell survival than untreated cells. Hence, these findings suggest that PV-E and TF-E priming could be used to attain improved cellular responses and enhanced therapeutic efficacy in burnt tissue.

Induction and Characteristics of Callus Cultures of the Medicinal Plant Tussilago farfara L

Tussilago farfara L. is a traditional medicinal plant valued for its potentially health-promoting metabolites. Its herbal raw material has been recognized and used since ancient times and continues to be widely used in traditional medicine. Introducing this plant species to in vitro cultivation is a challenging task, but once the protocol is developed, such cultures can provide an abundant and inexhaustible source of plant material. In this study, we report the successful induction and growth of vigorous T. farfara callus in vitro. Callus induction was achieved on MS solid media with the combination of indole-3-acetic acid (3 mg/L) and benzyl aminopurine (2 mg/L) in darkness, whereas it appeared inefficient under light conditions and in suspension culture. We present a detailed description of callus growth kinetics, morphological analysis, photosynthetic activity, and biochemical parameters (including protein content and photosynthetic pigments) supported by histological studies. Furthermore, we observed the potential for organogenesis and somatic embryogenesis. This method for the in vitro propagation of T. farfara, along with callus culture maintenance, offers a wide range of applications in pharmacy for the production of valuable metabolites. Moreover, it could benefit the environment by reducing the depletion of natural populations of this species and may serve as an alternative strategy for species conservation in light of global warming.

Comparison of the difference in the anti-inflammatory activity of two different color types of Farfarae Flos based on in vitro, in vivo experiments and untargeted metabolomics

Introduction

Due to its remarkable anti-inflammatory pharmacological activity, Farfarae Flos has gained extensive usage in the treatment of various inflammatory diseases such as bronchitis, pneumonia, prostatitis and colitis. And Farfarae Flos come in two color types depending on the color of the flowers: yellowish-white (YW), and purplish-red (PR). However, the difference in anti-inflammatory activity and metabolic profiles between the two flower colors remains unexplored.

Methods

This study aims to explore the difference in the anti-inflammatory potential between YW and PR variants of Farfarae Flos and unravel the mechanisms responsible for the observed differences in anti-inflammatory activity through an integrated approach encompassing untargeted metabolomics and in vivo/vitro experimental studies. Initially, we verified the contrasting effects of YW and PR on the inhibition of the inflammatory factors interleukin-6 (IL-6) and nitric oxide (NO) by utilizing an in vitro RAW 264.7 cell inflammation model. Subsequently, a comprehensive evaluation of the systemic inhibitory capacity of YW and PR on IL-6, Interleukin-10 (IL-10), and tumor necrosis factor-α (TNF-α) was conducted using a validated whole-body mouse model, followed by the analysis of inflammatory factors and histological examination of collected serum, liver, and spleen after 7 days. Furthermore, non-targeted metabolomics profiling was employed to analyze the metabolite profiles of Farfarae Flos with different colors, and quantitative analysis was conducted to identify differential metabolites between YW and PR. The correlation between the anti-inflammatory activities of differentially accumulated metabolites (DAMs) and Farfarae Flos was investigated, resulting in the identification of 48 compounds exhibiting significant anti-inflammatory activity. Additionally, KEGG pathway enrichment analysis was performed to elucidate the underlying mechanisms.

Results

Our findings demonstrate that both YW and PR possess anti-inflammatory abilities, with PR exhibiting significantly superior efficacy. The integration of in vivo/vitro experiments and non-targeted metabolomics confirmed the exceptional anti-inflammatory potential of PR and solidified its classification as the "purplish-red better" of Farfarae Flos.

Discussion

This study provides valuable insights into the breeding and medical transformation of Farfarae Flos varieties, along with a scientific basis for the establishment of quality standards and the development of new drugs utilizing Farfarae Flos.

Multicomponent qualitative and quantitative analysis of Farfarae Flos in serum using UHPLC-Q TOF-MS

Farfarae Flos is a traditional herb widely employed for treating coughs, bronchitis, and asthmatic disorders. In the current study, we utilized SWATH and IDA data acquisition modes in combination with multiple data processing techniques to identify Farfarae Flos metabolites in mice serum. A total of 56 compounds were characterized, including 31 phenolic acids, 13 flavonoids, 11 sesquiterpenoids and 1 alkaloid. Further quantitative analysis was conducted on 12 absorbed metabolites, utilizing a newly developed and rigorously validated analytical method. Our approach demonstrated an acceptable level of specificity, accuracy, precision, and stability. When applied to compare the serum of mice treated with FF, all 12 metabolites showed the highest concentration at 0.5 h. Overall, this study presented a novel strategy for unraveling the active compounds of FF via serum pharmacochemistry analysis, which made a foundation for exploring the pharmacodynamic material basis of FF.

Middle Eastern Plants with Potent Cytotoxic Effect Against Lung Cancer Cells

Cancer is one of the leading causes of increasing global mortality with uprising health concerns and threats. Unfortunately, conventional chemotherapy has substantial side effects, limiting its relevance and prompting a quest for safe and efficient alternatives. For thousands of years, plants have provided a rich reservoir for curing a variety of ailments, including cancer. According to the World Health Organization, medicinal plants would be the best source of medications. However, only 25% of drugs in the present pharmacopoeia are derived from plants. Hence, further research into different plants is required to better understand their efficacy. Twenty extracts of widely distributed Middle Eastern plants were screened for the cytotoxic effect against lung cancer cell lines (A549). Eleven plants showed IC50 below 25 μg/mL, consequently, the bioactive extracts were further fractionated by graded precipitation using absolute ethanol. All fraction A (FA; crude polysaccharides precipitate) showed potent IC50, 0.2-5.5 μg/mL except the FA of Brassica juncea, Silybum marianum, and Phaseolus vulgaris, whereas FB fractions (filtrate) of Anastatica hierochuntica, Plantago ovate, Tussilago farfara, and Cucurbita moschata had lower efficacy than other fractions with IC50 values in the range of 0.1-7.7 μg/mL. The fractions of FA Taraxacum officinale and FB Ziziphus spina possess the most potent cytotoxic activity with IC50, 0.2 and 0.1 μg/mL, respectively. Moreover, cell cycle analysis of both fractions revealed an arrest at G1/S-phase and activation of apoptosis rather than necrosis as the mode of cell death. Therefore, T. officinale and Z. spina fractions may pave the way to manage lung carcinoma as an alternative and complementary food regimen.

Halophytic Clonal Plant Species: Important Functional Aspects for Existence in Heterogeneous Saline Habitats

Plant modularity-related traits are important ecological determinants of vegetation composition, dynamics, and resilience. While simple changes in plant biomass resulting from salt treatments are usually considered a sufficient indicator for resistance vs. susceptibility to salinity, plants with a clonal growth pattern show complex responses to changes in environmental conditions. Due to physiological integration, clonal plants often have adaptive advantages in highly heterogeneous or disturbed habitats. Although halophytes native to various heterogeneous habitats have been extensively studied, no special attention has been paid to the peculiarities of salt tolerance mechanisms of clonal halophytes. Therefore, the aim of the present review is to identify probable and possible halophytic plant species belonging to different types of clonal growth and to analyze available scientific information on responses to salinity in these species. Examples, including halophytes with different types of clonal growth, will be analyzed, such as based on differences in the degree of physiological integration, ramet persistence, rate of clonal expansion, salinity-induced clonality, etc.

Tussilagone attenuates atherosclerosis through inhibiting MAPKs-mediated inflammation in macrophages

Atherosclerosis is a common chronic inflammatory disease. Recent studies have highlighted the key role of macrophages and inflammation in process of atherosclerotic lesion formation. A natural product, tussilagone (TUS), has previously exhibited anti-inflammatory activities in other diseases. In this study, we explored the potential effects and mechanisms of TUS on the inflammatory atherosclerosis. Atherosclerosis was induced in ApoE^-/- mice by feeding them with a high-fat diet (HFD) for 8 weeks, followed by administration of TUS (10, 20 mg ·kg^-1·d^-1, i.g.) for 8 weeks. We demonstrated that TUS alleviated inflammatory response and reduced atherosclerotic plaque areas in HFD-fed ApoE^-/- mice. Pro-inflammatory factor and adhesion factors were inhibited by TUS treatment. In vitro, TUS suppressed foam cell formation and oxLDL-induced inflammatory response in MPMs. RNA-sequencing analysis indicated that MAPK pathway was related to the anti-inflammation and anti-atherosclerosis effects of TUS. We further confirmed that TUS inhibited MAPKs phosphorylation in plaque lesion of aortas and cultured macrophages. MAPK inhibition blocked oxLDL-induced inflammatory response and prevented the innately pharmacological effects of TUS. Our findings present a mechanistic explanation for the pharmacological effect of TUS against atherosclerosis and indicate TUS as a potentially therapeutic candidate for atherosclerosis.

Effect of Adulteration on Quality and Preliminary Risk Assessment of the Decoction Pieces of Farfarae Flos Based on the Determination of Hepatotoxic Pyrrolizidine Alkaloids by UHPLC-MS/MS

BACKGROUND

Farfarae Flos (FF) is a frequently used traditional herbal medicine with outstanding antitussive actions. The adulteration of FF decoction pieces is common.

OBJECTIVE

This study aimed to study the effect of adulteration on the safety and quality of FF decoction pieces.

METHODS

The proportion of impurities was conducted by cone quartering method. A simple and accurate ultra-high-performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method was established to simultaneous determinate three pyrrolizidine alkaloids (PAs) as endogenous toxic compounds in FF. The traditional medicinal parts (flower bud), impurities (pedicel and rhizome) and unselected samples were determined respectively. The values of estimated daily intake (EDI) and margin of exposure (MOE) were used for risk assessment.

RESULTS

Twenty batches of samples were collected from different habitats, and the proportion of impurities ranged from 17.51% to 41.27%. Pedicel and rhizome were the main impurities, accounting for more than 87.40% of the total impurities. The content of PAs in impurities was significantly higher. The EDI value range was 5.34 to 16.59 μg/kg bw/day, which was much higher than the standard safety value of 7.00 × 10-3 μg/kg bw/day. The MOE values ranges for life long time and shorter exposure were 14.29 to 44.37 and 371.53 to 1153.63, respectively, indicating that at least 80% of the samples had safety risks. Correlation analysis showed that the proportion of adulterated impurities had significant correlation with the values of EDI and MOE.

CONCLUSIONS

Adulteration of non medicinal parts may significantly increase the risk of medications of FF decoction pieces.

HIGHLIGHTS

This study provides an efficient methodology reference for the control of PAs and a basis for adulteration to affect the safety and quality of FF decoction pieces.

How Do Herbal Cigarettes Compare To Tobacco? A Comprehensive Review of Their Sensory Characters, Phytochemicals, and Functional Properties

Herbal cigarettes, known as tobacco-free or nicotine-free cigarettes, are those recognized as being-tobacco free, being composed of a mixture of various herbs claimed to lessen the smoking habit hazards. However, controversial data regarding its properties occur in the literature with no comprehensive overview or analysis of its effects. Like herbal smokeless tobacco, they are often used to substitute for tobacco products (primarily cigarettes) regarded as a "nonsmoking" aid. This review capitalizes on herbal cigarettes with regard to their quality characteristics, sensory attributes, chemical composition, and health properties to rationalize their choice as a nonsmoking aid. Furthermore, the impacts of heat and/or pyrolysis that occur during smoking on its chemical composition are presented for the first time. Some herbal smokes may produce notable metabolic problems that increase the risk of several chronic metabolic diseases. In general, burning substances from plants can have a variety of negative effects on the body attributed to toxic chemicals such as carbon monoxide, polyaromatics, nicotine, and N-nitrosamines. This review compiles and discusses the phytochemical compositions detected in various herbal cigarettes alongside sensory and quality attributes and health effects.

Traditional ecological knowledge to traditional foods: The path to maintaining food sovereignty in Hutsulshchyna

The various ecosystems of the Carpathian Mountains spanning Europe, are a rich refuge for culturally important, endemic plant species as well as large carnivores. These biologically diverse landscapes are a principal source of subsistence to 16 million people, including various ethnographic groups. This paper focuses on a case study involving Hutsul communities, an ethnographic group of traditional pastoral highlanders, in the Southeastern Carpathian Mountains of Ukraine. Given ecosystem, climatic, and cultural challenges, especially the rise of illegal logging, commercial harvesting, increased frequencies of flooding, and now a war, Hutsul communities face extensive threats to maintaining socio-ecological resilience in the region. A contributing factor to the region's centuries-long resilience is traditional ecological knowledge upholding food sovereignty as seen through traditional foods derived from Carpathian Mountain ecosystems. Traditional ecological knowledge (TEK) is as a dynamic, generationally-held knowledge base, where language, gathering practices, landscape and culture inform livelihoods. In this article, we seek to answer the following series of questions within Hutsul communities: (1) What does TEK look like in the region? (2) What are the regional environmental challenges? (3) Given these challenges, what are coping mechanisms and adaptive strategies grounded in TEK, ensuring a resilient food sovereign system? Mixed methodologies guided by community-based participatory action research methods (CBPAR) between 2017 and 2019 provide a rich, context-driven perspective on regional TEK. Radiating out from the historical, cultural Hutsul capital, Verkhovyna, 40 experts (including knowledge holders, elders, foresters, and community members) were interviewed in 8 neighboring villages. We, along with Hutsul experts, explore the presence of traditional ecological knowledge (TEK) in Hutsulshchyna by identifying 108 culturally important species including wild plants (74 species), cultivated plants (23 species), fungi (9 species) and lichens (2 species); these species are gathered in 10 habitats with varying degrees of human interaction. We analyze species' presence in traditional foods in the past and present day, as well as contextualize regional environmental challenges impacting TEK practices, and responses to these challenges (coping mechanisms and adaptive strategies). Despite various regional challenges, we conclude that TEK provides a resilient foundation for supporting food sovereignty as seen through the presence of traditional foods.

It also imposes socioeconomic burdens on patients. Natural treatment is cheap and claimed to be safe. The use of plants is as old as mankind. Many medicinal plants and their parts are frequently used to treat these diseases, and they are also suitable raw materials for the production of new synthetic agents. A review of some plant families, viz., Fabaceae, Asteraceae, Lamiaceae, etc., used in the treatment of skin diseases is provided with their most common compounds and in silico studies that summarize the recent data that have been collected in this area.

Herbal Medicine Uses for Respiratory System Disorders and Possible Trends in New Herbal Medicinal Recipes during COVID-19 in Pasvalys District, Lithuania

Despite some preliminary studies of the available herbal medicine preparations and their curative effects on COVID-19, experts still fear that unproper use of such homemade medicines could do more harm than good to people relying on unproven alternatives of questionable efficacy. The main purpose of this study was to evaluate the safety of herbal medicines used for respiratory system disorders in the Pasvalys district during the COVID-19 pandemic in Lithuania. An archival source was also studied, looking for possible recipes for the treatment and prevention of respiratory diseases in Lithuanian traditional medicine, emphasizing the safety guidelines. The survey was conducted using the deep interview method. The respondents mentioned 60 species of medicinal plants from 29 different families used for the treatment and prevention of respiratory system disorders (for cough mostly, 51.70% of all indications). Twenty eight out of 60 plant species were not included in the European Medicines Agency monographs and only 50% of all included species were used as indicated by the European Medicines Agency for respiratory system disorders. The trends in the ethnopharmacological choices of modern consumers and the analysis of archival sources can be a great source of ideas for new herbal-based pharmaceutical preparations for COVID-19 symptoms in Lithuania considering the safety recommendations.

Ethnomedicinal and Ethnobotanical Survey in the Aosta Valley Side of the Gran Paradiso National Park (Western Alps, Italy)

Most of traditional knowledge about plants and their uses is fast disappearing because of socio-economic and land use changes. This trend is also occurring in bio-cultural refugia, such as mountain areas. New data on Traditional Ethnobotanical Knowledge (TEK) of Italian alpine regions were collected relating to three valleys (Cogne, Valsavarenche, Rhêmes) of the Gran Paradiso National Park. Extensive dialogues and semi-structured interviews with 68 native informants (30 men, 38 women; mean age 70) were carried out between 2017 and 2019. A total of 3918 reports were collected, concerning 217 taxa (including 10 mushrooms, 1 lichen) mainly used for medicinal (42%) and food (33%) purposes. Minor uses were related to liquor making (7%), domestic (7%), veterinary (5%), forage (4%), cosmetic (1%) and other (2%). Medicinal plants were used to treat 14 ailment categories, of which the most important were respiratory (22%), digestive (19%), skin (13%), musculoskeletal (10%) and genitourinary (10%) diseases. Data were also evaluated by quantitative ethnobotanical indexes. The results show a rich and alive traditional knowledge concerning plants uses in the Gran Paradiso National Park. Plants resources may provide new opportunities from the scientific point of view, for the valorization of local products for health community and for sustainable land management.

Research on the effect of spleen-invigorating and anti-swelling active ingredients in crude and processed coix seed based on Spectrum - Effects relationship combined with chemometrics

Coix seed (CS) is the dry mature seed kernel of Coix lacrma-jobi L. var. mayuen (Roman.) Stapf, which has the effect of spleen-invigorating and anti-swelling. However, research reports on the main active ingredients of CS were minimal. The purpose of this study was to find the main active ingredients that affect the efficacy of CS to invigorate the spleen and reduce swelling through the spectrum-effect relationship, combined with chemometrics, grey relational analysis (GRA) and entropy method, and to compare the differences between the effects of crude and processed CS. First of all, the HPLC-ELSD method was used to establish the chromatographic fingerprint of CS, and 12 batches of CS samples were analyzed through chemometrics in this study. Then, we studied the effect of spleen-invigorating and anti-swelling in CS. Finally, through grey relational analysis and entropy method, the spectrum-effect relationship between the chromatographic fingerprint and the seven pharmacodynamic effect indexes was studied. The results showed that the main pharmacologically active ingredients were 1,3-Dioleoyl-2-palmitoylglycerol (peak 8), 1,2-dilinoleoyl-3-oleoyl-rac-glycerol (peak 2), 1,3-Dipalmitoyl-2-Linolein (peak 5), 1,2-Dilinoleoyl-3-palmitoyl-rac-glycerol (peak 3), 1,2-Dioleoyl-3-linoleoyl-rac-glycerol (peak 4), and glycerol trioleate (peak 7), and the comprehensive efficacy of bran-fried CS was better than that of raw CS. In summary, we have identified the main active ingredients related to the efficacy of CS. As far as we know, this is the first time that the crude and processed CS spectrum-effect relationship has been established and compared, which provides a theoretical basis for subsequent studies on the material basis and molecular mechanism of CS pharmacodynamics.

Extraction and determination of tussilagone from Farfarae Flos with online solid-phase extraction-high-performance liquid chromatography using a homemade monolithic cartridge doped with porous organic cage material

A solid-phase extraction cartridge was fabricated using diallyl isophthalate as the monomer with the addition of porous organic cage material via in situ free-radical polymerization in a stainless-steel column. The resulting monolithic adsorbent exhibited a relatively uniform porous structure, a high specific surface area of 113.98 m² /g, and multiple functional chemical groups according to the characterization results. An online solid-phase extraction-high-performance liquid chromatography procedure was fabricated to extract and determine tussilagone from Farfarae Flos. The results show that the complex sample matrices can be removed in the solid-phase extraction procedure. Simultaneously, tussilagone can remain, which can be subsequently switched to an octadecylsilane bonded analytical column. The methodological validation showed that the correlation coefficient was 0.9999 with a linear range of 0.6-200.0 µg/mL, the limit of detection was 0.2 µg/mL, the limit of quantification was 0.6 µg/mL, accuracy was 100.3-100.6%, and relative standard deviation of precision was ≤1.9%. The present monolithic cartridge exhibits good reusability of not more than 100 times. The real sample of Farfarae Flos was determined with a tussilagone content of 0.74 mg/g.
