Study on mechanism of Qinbaohong Oral Liquid in anti-inflammation, stopping cough, eliminating phlegm and relieving asthma based on network pharmacology

This study aimed to investigate the anti-inflammatory, antitussive, expectorant, and anti-asthmatic effects of Qinbaohong Oral Liquid in mouse experiments and explore its action mechanism based on network pharmacology. The mouse auricle swelling was induced by xylene for detecting the anti-inflammatory effect of Qinbaohong Oral Liquid, whose antitussive effect was then examined in mice with cough after exposure to ammonium hydroxide. The expectorant effect was determined based on the excretion of phenol red into the mouse trachea. The mouse model of asthma induced by histamine phosphate and acetylcholine chloride was used to observe the anti-asthmatic effect. The chemical components of Qinbaohong Oral Liquid were retrieved from TCMSP and literature, followed by target prediction based on BATMAN-TCM. The targets of inflammation, cough, expectoration, and asthma collected from GeneCards were intersected with drug targets for GO and KEGG enrichment analysis using Metascape. The results were imported into STRING for exploring protein-protein interactions and screening the key targets. As demonstrated by our findings, Qinbaohong Oral Liquid at 4.5 and 9.0 mL·kg~(-1) obviously decreased the weight(P<0.05) and thickness(P<0.01) of the right swelling ear and also the weight diffe-rence(swelling degree) between the two ears(P<0.05), prolonged the incubation period of cough(P<0.05), reduced the frequency of cough within 3 min(P<0.05), and increased the excretion of phenol red into the mouse trachea(P<0.01). Qinbaohong Oral Li-quid at 2.3, 4.5, and 9.0 mL·kg~(-1) dramatically prolonged the incubation period of asthma(P<0.05). A total of 324 chemical components and 1 245 targets were harvested for the Qinbaohong Oral Liquid, together with 10 272 inflammation targets, 4 400 cough targets, 192 expectoration targets, and 7 533 asthma targets. Their intersection revealed that the anti-inflammatory, antitussive, expectorant and anti-asthmatic effects of Qinbaohong Oral Liquid were correlated with such GO biological processes as the regulation of ion transport and blood circulation and such KEGG pathways as cancer-related signaling pathways and neuroactive ligand-receptor interaction. Qinbaohong Oral Liquid has been confirmed by both experiments and network pharmacology analysis to be efficient in anti-inflammation, stopping cough, eliminating phlegm, and relieving asthma.

Chemical Analysis by LC-MS of Cannabis sativa Root Samples from Northeast Brazil and Evaluation of Antitussive and Expectorant Activities.

Cannabis sativa is a millenary medicinal plant. However, contrary to worldwide paradigm-shifting, countries like Brazil still prohibit C. sativa cultivation and its medicinal use, even though many populations use aerial parts and roots of this plant for healthcare. As such, the objective of this work was to identify substances in the samples of the C. sativa roots, tracing a correlation with antitussive and expectorant effects. Therefore, samples of C. sativa roots were donated by the Polícia Federal Brasileira, and its aqueous extract (AECsR) was prepared with subsequent lyophilization, to maintain the material stability. After that, the material was analyzed by LC-MS to observe its chemical profile. Four samples (AECsR-A, B, C, and D) were tested in animal models of citric acid-induced cough (0.4 M) and phenol red expectoration (500 mg/kg). Using LC-MS it was possible to identify 5 molecules in C. sativa roots: p-coumaroyltyramine, tetrahydrocannabinol-C4, feruoiltyramine, anhydrocanabisativine, and cannabisativine. In experimental protocols, male mice (Mus musculus) were treated with samples of AECsR at doses of 12.5, 25, or 50 mg/kg regardless of the pharmacological test. In these tests, all samples showed the potential to treat cough and promote fluid expectoration, differing only in the dose at which these effects were observed. Therefore, the data showed that the C.sativa roots of the Brazilian Northeast showed antitussive and expectorant effects, even with intense secondary metabolites' variation, which alters its potency, but not its effect. This highlights the importance of this medicinal plant for future therapy and corroborates to traditional use.

Simultaneous determination of multiple components in Farfarae Flos by UHPLC-DAD and its application in quality control of decoction pieces

Farfarae Flos is a frequently used traditional herbal medicine, with outstanding antitussive, anti-asthmatic and expectorant effects. The current quality standard cannot effectively evaluate the quality of decoction pieces, or reflect the quality difference between medicinal parts and impurities. Herein, a simple, rapid, and accurate ultra high-performance liquid-chromatography diode-array (UHPLC-DAD) method was established for the simultaneous determination of 14 components in Farfarae Flos within 15 minutes. Different parts of the plant (flower bud, corolla, pedicel and stem) of 20 batches of decoction pieces were determined by the established method. Chemometrics was applied to assess the proposed method and analyze the quantitative results. Principal component analysis showed that the phenolic acids, flavonoids and terpenoids were effective quality control markers for Farfarae Flos. The quality of traditional medicinal part (flower bud) was significantly different from that of impurities (pedicel and stem). ANOVA showed that the content of phenolic acids in the pedicel and stem was significantly higher than that in the flower bud, while the content of flavonoids in the pedicel and stem was significantly lower than that in the flower bud. This study provides an efficient and low-cost methodology with adequate sensitivity for the quality control of Farfarae Flos decoction pieces.

Anti-neuroinflammatory activity of 6,7-dihydroxy-2,4-dimethoxy phenanthrene isolated from Dioscorea batatas Decne partly through suppressing the p38 MAPK/NF-κB pathway in BV2 microglial cells

Ethnopharmacological relevanceThe rhizome of Dioscorea batatas Decne (called Chinses yam) widely distributed in East Asian countries including China, Japan, Korea and Taiwan has long been used in oriental folk medicine owing to its tonic, antitussive, expectorant and anti-ulcerative effects. It has been reported to have anti-inflammatory, antioxidative, cholesterol-lowering, anticholinesterase, growth hormone-releasing, antifungal and immune cell-stimulating activities. Aim of the studyNeuroinflammation caused by activated microglia contributes to neuronal dysfunction and neurodegeneration. In the present study, the anti-neuroinflammatory activity of 6,7-dihydroxy-2,4-dimethoxy phenanthrene (DHDMP), a phenanthrene compound isolated from Dioscorea batatas Decne, was examined in microglial and neuronal cells. Materials and methodsA natural phenanthrene compound, DHDMP, was isolated from the peel of Dioscorea batatas Decne. The anti-neuroinflammatory capability of the compound was examined using the co-culture system of BV2 murine microglial and HT22 murine neuronal cell lines. The expression levels of inflammatory mediators and cytoprotective proteins in the cells were quantified by enzyme-linked immunosorbent assay and Western blot analysis. ResultsDHDMP at the concentrations of ≤1 μg/mL did not exhibit a cytotoxic effect for BV2 and HT22 cells. Rather DHDMP effectively restored the growth rate of HT22 cells, which was reduced by co-culture with lipopolysaccharide (LPS)-treated BV2 cells. DHDMP significantly decreased the production of proinflammatory mediators, such as nitric oxide, tumor necrosis factor-α, interleukin-6, inducible nitric oxide synthase, and cyclooxygenase-2 in BV2 cells. Moreover, DHDMP strongly inhibited the nuclear translocation of nuclear factor κB (NF-κB) and phosphorylation of p38 mitogen-activated protein kinase (MAPK) in BV2 cells. The compound did not affect the levels and phosphorylation of ERK and JNK. Concurrently, DHDMP increased the expression of heme oxygenase-1 (HO-1), an inducible cytoprotective enzyme, in HT22 cells. ConclusionsOur findings indicate that DHDMP effectively dampened LPS-mediated inflammatory responses in BV2 microglial cells by suppressing transcriptional activity of NF-κB and its downstream mediators and contributed to HT22 neuronal cell survival. This study provides insight into the therapeutic potential of DHDMP for inflammation-related neurological diseases.

Study on the Effect of Deep Eutectic Solvent Liquid Phase Microextraction on Quality Standard, Antitussive, and Expectorant of Sangbaipi Decoction.

The SD was extracted with a new green eutectic solvent, and the extraction method of TCM decoction was developed. In the quantitative analysis by HPLC, choline chloride phenol was selected as the eutectic solvent, THF was used as the extractant, and investigation of DES type, DES molar ratio, DES-to-THF ratio, vortex time, and material-to-liquid ratio was carried out. The experimental results showed that the optimal extraction method was as follows: the molar ratio of DES was 1 : 3, and the material-liquid ratio was 5 : 1200 (mL/μL). The volume ratio of DES to THF was 1200 : 800 (μL), the vortex time was 3 min, and the extraction was repeated two times. The eutectic solvent liquid phase microextraction method was adopted to optimize the extraction method of SD and reduce the complicated processing, long time, and low efficiency of traditional methods. At the same time, in the mouse ammonia water inducing cough and phenol red excretion and expectorant experiments, SD high- and medium-dose groups have a significant inhibitory effect on the frequency of antitussive in mice and both can increase the excretion of phenol red to varying degrees, indicating that SD has good cough-relieving and expectorant effect. The present study suggests a scientific basis and basis for the clinical research and quality standard formulation of SD.

Topical aspects of the use of phytopreparations in acute infectious and inflammatory diseases of the upper respiratory tract

Acute infectious and inflammatory diseases of the upper respiratory tract today belong to the category of the most common pathological conditions. Most often they occur in the form of acute nasopharyngitis, acute rhinosinusitis and acute laryngitis, the clinical of which consists of such symptoms as general weakness, hyperthermia, nasal blockage and nasal discharge, dysosmia, pain and tickling in the throat, cough, dysphonia. The need to select a safe and effective mucoactive therapy justifies the use of the phytopreparation in this pathology, the main active ingredient of which is an extract of ivy leaves. Also in the composition of the drug includes anise oil, peppermint oil, eucalyptus oil and levomenthol. The mechanism of action of is associated with α-hederin contained in ivy leaves. This substance, binding to the beta-adrenoreceptors of the bronchi, causes relaxation of their smooth muscles. In addition, thanks to the saponins contained in the leaves of common ivy, a mucolytic and expectorant effect is achieved. Literature data show that ivy leaf preparations significantly reduce the severity of acute respiratory infections of the upper respiratory tract. Virtually none of the patients had severe side effects. Allergic reactions were recorded in less than 0.5% of cases, with no mention of a severe allergic reaction of the anaphylaxis type. Thus, the drug of plant origin in the form of drops can be successfully used in patients with symptoms of acute respiratory diseases.

Effects of a Mixture of Ivy Leaf Extract and Coptidis rhizome on Patients with Chronic Bronchitis and Bronchiectasis

Background: Hederacoside C from ivy leaf dry extracts (HH) and berberine from Coptidis rhizome dry extracts (CR) can be combined (HHCR) as a herbal product. Previous studies have demonstrated that HHCR has antitussive and expectorant effects in animal models of respiratory disease. However, the therapeutic effects of HHCR on respiratory diseases in humans have not been well-studied. Therefore, we aimed to clarify the effectiveness of HHCR in patients with chronic bronchitis and bronchiectasis. Methods: This was a multicenter (10 university teaching hospitals), open-label, prospective, single-arm, observational study. Consecutive patients with chronic bronchitis and bronchiectasis were included. Patients were orally treated with HHCR daily for 12 weeks. St. George’s Respiratory Questionnaire (SGRQ) scores and bronchitis severity scores (BSS) were measured at baseline and at the end of the 12-week study. Results: In total, 376 patients were enrolled, of which 304 were finally included in the study, including 236 males and 68 females with a median age of 69 years (range: 37–88 years). After 12 weeks of HHCR treatment, there was a significant improvement in SGRQ score (baseline, 32.52 ± 16.93 vs. end of study, 29.08 ± 15.16; p < 0.0001) and a significant reduction in BSS (baseline, 7.16 ± 2.63 vs. end of study, 4.72 ± 2.45; p < 0.0001). During the study, 14 patients concomitantly used an inhaled corticosteroid and 83 patients used an inhaled bronchodilator. HHCR also had significant positive effects on these patients in terms of SGRQ score and BSS. No serious adverse drug reactions occurred during HHCR treatment. Conclusions: treatment with HHCR improved the SGRQ score and BSS in patients with chronic bronchitis and bronchiectasis. HHCR may be a new therapeutic option for chronic bronchitis and bronchiectasis. Large-scale, randomized, double-blind, placebo-controlled clinical trials are warranted.

Deciphering the Antitussive, Expectorant, and Anti-Inflammatory Potentials of ShashamKyeongok-Go and Their Phytochemical Attributes: In Vivo Appraisal in ICR Mice

In this paper, we hypothesized that ShashamKyeongok-go (SKOG) is a mixed preparation of Adenophorae Radix powder (AR) and Kyeongok-go (KOG). SKOG may be served as a novel preventive and/or therapeutic agent for various respiratory diseases. SKOG were orally administered to ICR mice at 400, 200, and 100 mg/kg once a day for 11 days to examine antitussive, expectorant, and anti-inflammatory effects. The NH4OH exposure-induced allergic acute inflammation with coughing responses was dose-dependently and significantly (p &lt; 0.01) inhibited by pretreatment with SKOG at doses of 400, 200, and 100 mg/kg. With these concentrations of SKOG, the thickness of intrapulmonary secondary bronchus mucosa and the number of periodic acid Schiff stain-positive mucous-producing cells were significantly (p &lt; 0.05 or p &lt; 0.01) increased, as a result of the increased amount of phenol red secretion. Subsequently, SKOG showed significant (p &lt; 0.01) anti-inflammatory activities as characterized by reducing the effects of xylene-induced increases of ear weight, thickness of total ear and ear dermis, and number of infiltrated inflammatory cells in the ear dermis, in a dose-dependent manner. These results supported that SKOG might have potential therapeutic effects to be used as an antitussive, expectorant, and anti-inflammatory agents in the prevention or treatment of chronic bronchitis and asthma.

Characterization of chemical profile and quantification of major representative components of Wendan decoction, a classical traditional Chinese medicine formula.

Wendan decoction, a classical traditional Chinese medicine formula consisting of six herbal medicines, has been widely used in clinical treatments for thousands of years due to the expectorant effects. However, the chemical basis of Wendan decoction remains unclear, which hinders the elucidation of the scientific connotation and mechanism of its effective components. In this study, an ultra-high performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry method was first developed for characterization of its chemical profile, and a total of 142 chemical components including flavonoids, triterpenoids, alkaloids, coumarins, pungent phytochemicals, and other types were detected, among which 41 components were definitively identified with authentic standards. Furthermore, 14 major representative components were simultaneously quantified by high-performance liquid chromatography with ultraviolet detector, indicating that the content levels of flavonoids were the most abundant in Wendan decoction. In summary, this study established sensitive and practical methods to systematically characterize chemical profile for the first time and simultaneous quantify representative components of Wendan decoction. These findings above would provide a solid chemical basis for disclosure of potential effective components by further in vivo disposal study, and promote therapeutic mechanism researches of Wendan decoction.

Investigation of the Inhibitory Effect of Platycodin D in Human Transitional Cell Carcinoma Cell Line 5637

Platycodin D is an active component isolated from Chinese herb Platycodonis radix with various pharmacological activities, such as antitussive, expectorant, anti-inflammatory, and analgesic effects. Interestingly, platycodin D also exerts anticancer effects against several types of cancer. However, few studies on the anti-tumour effects of platycodin against urinary bladder cancer have been reported. In this study, we explored the anti-tumour effect of platycodin D against human bladder cancer and its mechanisms in vitro and in vivo. We found that platycodin D had significant anti-proliferative effects on four types of cancer cells, especially the 5637 bladder cancer cell line, and exerted these effects by preventing cell cycle progression from G0/G1 to S phase, down-regulating Ki-67 and cyclin D1 protein expression and up-regulating P21 protein expression. Furthermore, platycodin D inhibited 5637 cell migration by decreasing twist-related protein 1 (Twist1) and matrix metallopeptidase 2 (MMP2) expression and exerted significant tumour-suppressive effects in tumour-bearing nude mice. Platycodin D also increased caspase-9, caspase-8, caspase-3, and p53 expression and decreased Bcl-2 expression in tumour tissues. Taken together, our results provide a theoretical basis for application of platycodin D in treating urinary bladder cancer.

Раціональний вибір мукоактивних фітопрепаратів у педіатрії: комплексна фармакологічна дія, ефективність, безпечність

Cough is one of the most common symptoms of acute respiratory viral infections in childhood. In the treatment of acute respiratory infections accompanied by cough in children, the main task is to stop the cough by improving the rheological properties of bronchial secretions for their early withdrawal. Cough can be effectively treated only by improving the discharge of mucus from the respiratory tract. For this purpose, mucoactive drugs are used: secretolytics, capable of thinning mucus (mucolytic action), and secretomotor drugs, which improve its output (expectorant effect). Among the many mucoactive drugs in pediatrics, preference is given to herbal drugs, which have a milder expectorant effect compared to synthetic drugs, and are better tolerated. On the Ukrainian pharmaceutical market there is Gederin Ivy Syrup, a preparation with ivy extract. Among the complex of effects of the ivy leaf extract (expectorant, secretolytic, anti-inflammatory), the unique action that distinguishes it from other herbal and synthetic drugs is bronchospasmolytic one. Taking this into account, preparations with ivy extract can be recommended for respiratory infections accompanied by obstruction. These can be both acute and chronic conditions occurring with reversible narrowing of the airways. Due to its natural composition, the drug is safe. Side effects from Gederin Ivy syrup are very rare. In patients with hypersensitivity to the components of the drug some allergic reactions (mainly rash), as well as gastrointestinal disorders are possible. It should not be administered to patients suffering from fructose intolerance. Sorbitol, which is a component of the syrup, can cause a slight laxative effect. Thus, the combination of such effects of ivy extract in the preparation Gederin Ivy – expectorant (mucokinetic and secretolytic), bronchospasmolytic and anti-inflammatory – predetermines its expressive clinical efficacy in the treatment of cough, as well as good tolerance. And this allows it to be widely used in the complex therapy of bronchitis in pediatric practice. No conflict of interest was declared by the authors. Key words: Mucoactive phytopreparations, children, treatment, ivy extract, efficacy, safety.

Bronhomed Balsam is a combined herbal preparation with pathogenetic and symptomatic action, which is used for colds of the respiratory tract. This preparation has antimicrobial, mucolytic, bronchodilator, expectorant, anti-inflammatory, sedative and diaphoretic effect. This review presents the discussion of the composition of the preparation in the context of therapeutic effects of its components. In the focus of attention is anise oil, which contains such active ingredients as anethole, shikimic acid and lignin-carbohydrate-protein complexes, which have antimicrobial and immunomodulatory effects. Another point discussed is the effect of anise oil on the nitric oxide system and the production of interferon gamma, which are important components of the anti-inflammatory and antimicrobial action of the preparation. It has been established that the inclusion of the combined herbal preparation Bronchomed Balsam in the complex of treatment of patients with acute respiratory viral infections allows to effectively stop major symptoms of the disease (in the absence of serious side effects), which indicates the therapeutic efficacy of and good tolerance of to the phytobalm. The therapeutic effect of Bronchomed Balsam is due to its anti-inflammatory, immunomodulatory, expectorant and antiseptic action. This allows to reduce the drug load on the patient's body and to optimize the symptomatic and pathogenetic treatment of acute respiratory viral infections. The author declares no conflicts of interest. Key words: Bronchomed Balsam, acute respiratory viral infections, anise oil.

Disseminated vegetating infantile bromoderma: A dramatic response to systemic steroids.

Bromoderma is a rare hypersensitivity reaction caused by bromide intake. It was relatively frequent in the early years of the previous century because of the common use of bromide-containing solutions in pediatrics due to their antispasmodic, expectorant, sedative, and anticonvulsant effects. Although recently prohibited in many countries, bromides are still used as an adjuvant anticonvulsant drug and still present in some over the counter antispasmodics and analgesics. Bromoderma usually present with pustular and vegetating lesions that may represent a diagnostic challenge for dermatologists. We describe a severe case of vegetating bromoderma that showed an excellent response to the withdrawal of the bromide-containing medication associated with systemic steroid administration.

The anti-tussive, anti-inflammatory effects and sub-chronic toxicological evaluation of perilla seed oil.

Perilla seed oil (PSO) is the main constituent of perilla seeds currently being used in the food industry, however it also has great clinical potential in the regulation of lung function as a nutrition supplement because of the high content of α-linolenic acid (ALA). In this study, the pharmacological activities including anti-tussive, expectorant and anti-inflammatory effect of PSO were performed. Furthermore, the 90-day sub-chronic oral toxicity with a 30 day recovery period was evaluated in Wistar rats. The pharmacological studies demonstrated that PSO inhibited cough frequency induced by capsaicine in mice. PSO also inhibited the leukotriene B4 (LTB4) release from the calcium ionophore A23187-induced polymorphonuclear neutrophils (PMNs) to some extent. In this sub-chronic toxicity study, mortality, clinical signs, body weight, food consumption, hematology, serum biochemistry, urinalysis, organ weight, necropsy, and histopathology were used to evaluate the toxicity of PSO. Lower body weight and various negative impacts on liver related parameters without histopathological lesion were observed in the 16 g kg-1 groups. No clinically significant changes were discovered in the 4 g kg-1 group during the test period. In summary, PSO exhibited anti-tussive and anti-inflammatory activities in vivo and in vitro. These sub-chronic toxicity studies inferred that the 'no-observed adverse effect level' (NOAEL) of PSO in Wistar rats was determined to be 4 g kg-1 . These results may provide a safety profile and a valuable reference for the use of PSO. © 2020 Society of Chemical Industry.

Evaluation of usage and time of glycine amino acid application on growth and vegetative organs yield and antioxidant activity of Hyssop (Hyssopus officinalis L .) under different irrigation conditions

IntroductionHyssop (Hyssopus officinalis L.) belongs to the family of Lamiaceae. woody, perennial, shrubs with short, four-stalks, with a height of 50 to 70 centimeters. Its small and reciprocal leaves, the sharp, perfect, very aromatic, and its beautiful flowers, dark blue to purple, white. This herb has a powerful, cough- Soothing, expectorant effect, more or less diuretic and stomach tonic. Drought stress, while decreasing green growth and yield, causes changes in antioxidant activity in this plant. In nature, different environmental stresses threaten the survival, yield and growth of plants. Drought stress is one of the most important environmental stresses limiting the production of plants around the world, especially in arid and semi-arid regions. Drought stress generally destroys and breaks down chloroplates and decreases chlorophyll content and decreases the amount of enzymes activity in the Calvin cycle during photosynthesis and ultimately reduces the growth and yield of the crop. The accumulation of compatible solutes is one of the effective mechanisms for modulating the stresses of dehydration or salinity. This regulation is performed by the production of more organic materials such as protein, soluble sugars, and amino acids such as glycine, proline, alanine and valine in the air and root organs. Glycine is one of the important amino acids in the environmental stresses and chemical formula is NH2-CH2-COOH. This research were investigate the effects of foliar application of glycine amino acid and its application time on growth and yield and antioxidant compounds of Hyssop under different irrigation conditions.Materials and methodsThe experiment was conducted as split plot factorial in a randomized complete block design with three replications of Yazd agricultural and natural resources research farm in 2016-2017. Irrigation at 25, 50, 75% of the available soil water from the soil, order to control, medium stress, severe stress as the main factor and foliar application treatments in two levels of distilled water (control) and glycine amino acid (2.5 per thousand) and two levels of foliar application (vegetative and just flowering, flowering) were considered as subplots. The measured traits included plant height, lateral branch number, leaf number, fresh and dry weight yield, total phenolic compounds flavonoid and anthocyanin levels. SAS software was used to analyze the data. Mean comparison was performed by LSD at the probability level of 5%.Results and discussionDifferent irrigation treatments reduced the number of lateral branches, number of leaf, fresh and dry weight yields, total phenol, but the anthocyanin content increased. No significant differences were observed between foliar application time treatments. Interaction effects showed that the combination of control irrigation and foliar application of glycine increased the height and number of lateral branches. Also this material in combination with irrigation mild and severe stress treatments levels increased leaf number, fresh and dry weight yield of plant compared to control. Conclusion The results of this present study indicated that the external application of glycine amino acid in addition to reducing the damage caused by water stress in the plant, also has increased the plant's ability to improve grow and enhance yield.

Evaluation of the Nomenclature of Herbal Expectorants on Russian Pharmaceutical Market: Current Status and Future Prospects

This review focuses on current data sources on medicinal plants possessing expectorant effects. The component characterization of biologically active compounds determining the specified pharmacological effect of herbal medicines was also described and analyzed. The nomenclature of expectorant drugs presented on the Russian pharmaceutical market was studied and trends have been identified. It is known that herbal preparations, as a rule, are multicomponent. Combined expectorant drugs that simultaneously affect various mechanisms of inflammation and cough are becoming increasingly popular in medical practice. It seems relevant to assess the proportion of the most commonly used components (as well as biologically active substances) that are currently used for the production of expectorant drugs. Expectorant herbal preparations may contain such groups of biologically active substances as polysaccharides, saponins, essential oils, alkaloids. Medicinal plant material with an expectorant effect is used to obtain liquid dosage forms: syrups, tinctures, infusions, decoctions, elixirs, drops, and oral solutions, as well as solid – tablets, capsules, granules, troches, powders. These drugs occupy their important niche in the pharmaceutical market of the Russian Federation.

Molecular mechanism underlying the anti-inflammatory effects of volatile components of Ligularia fischeri (Ledeb) Turcz based on network pharmacology

BackgroundLigularia fischeri (Ledeb) Turcz (LFT) is a well-known expectorant and active anti-inflammatory agent in Chinese traditional medicine. LFT’s expectorant effect is closely related to its anti-inflammatory effects. This study aimed to evaluate the differential composition and anti-inflammatory mechanisms of the volatile components in LFT from different production areas.MethodHeadspace solid-phase microextraction-gas chromatography-mass spectrometry analysis of volatile components, as well as chemometric methods, including similarity analysis, hierarchical clustering analysis, and principal component analysis, were performed to identify LFT produced in different areas. The molecular mechanism underlying the anti-inflammatory effects of these components was determined by network pharmacology analysis.ResultsWe observed significant differences in the chemical constituents and percentage contents in samples with different origins. Eighteen volatile components were identified in four different producing areas, among which the highest content of olefinic components was the main component of the aroma of LFT. The mechanisms of these pharmacological effects involved multiple targets and pathways. Twenty-seven potential target proteins and 65 signaling pathways were screened, and a “component-target-disease” interaction network map was constructed. The volatile components of the LFT function mainly by inhibiting the production of inflammatory factors.ConclusionThis study provides a theoretical framework for further development and application of LFT used in traditional Chinese medicine.Graphical abstract
