The burdock database: a multi-omic database for Arctium lappa, a food and medicinal plant.

BACKGROUND: Burdock is a biennial herb of Asteraceae found in Northern Europe, Eurasia, Siberia, and China. Its mature dry fruits, called Niu Bang Zi, are recorded in various traditional Chinese medicine books. With the development of sequencing technology, the mitochondrial, chloroplast, and nuclear genomes, transcriptome, and sequence-related amplified polymorphism (SRAP) fingerprints of burdock have all been reported. To make better use of this data for further research and analysis, a burdock database was constructed. RESULTS: This burdock multi-omics database contains two burdock genome datasets, two transcriptome datasets, eight burdock chloroplast genomes, one burdock mitochondrial genome, one A. tomentosum chloroplast genome, one A. tomentosum mitochondrial genome, 26 phenotypes of burdock varieties, burdock rhizosphere-associated microorganisms, and chemical constituents of burdock fruit, pericarp, and kernel at different growth stages (using UPLC-Q-TOF-MS). The wild and cultivation distribution of burdock in China was summarized, and the main active components and pharmacological effects of burdock currently reported were concluded. The database contains ten central functional modules: Home, Genome, Transcriptome, Jbrowse, Search, Tools, SRAP fingerprints, Associated microorganisms, Chemical, and Publications. Among these, the "Tools" module can be used to perform sequence homology alignment (Blast), multiple sequence alignment analysis (Muscle), homologous protein prediction (Genewise), primer design (Primer), large-scale genome analysis (Lastz), and GO and KEGG enrichment analyses (GO Enrichment and KEGG Enrichment). CONCLUSIONS: The database URL is http://210.22.121.250:41352/ . This burdock database integrates molecular and chemical data to provide a comprehensive information and analysis platform for interested researchers and can be of immense help to the cultivation, breeding, and molecular pharmacognosy research of burdock.

Structure elucidation and NMR spectral assignments of one new dammarane-type triterpenoid saponin from black ginseng.

New dammarane-type triterpenoid saponin, named 22(R)-notoginsenoside Ab1 (1), together with thirteen known dammarane-type triterpenoid saponins (2-14) was isolated from the EtOH extract of black ginseng and their structures were elucidated on the basis of one- and two-dimensional NMR (including 1H-NMR, 13C-NMR, HSQC, HMBC, ROESY) and calculated ECD. Among them, compounds 1-2 and 6-8 were isolated for the first time from ginseng and black ginseng. Besides, the absolute structure of 22(R)- and 22(S)- notoginsenoside Ab1 were distinguished by ECD for the first time.

Effects of hydroxysafflor yellow A on rats with collagen-induced arthritis.

Hydroxysafflor yellow A (HSYA) from safflower (Carthamus tinctorius L.) possesses several medicinal properties. However, it is unknown whether HSYA is effective in the treatment of rheumatoid arthritis (RA). Hence, we investigated the effects of HSYA on the inflammation and synovial damage in rats with collagen-induced arthritis (CIA) by subjecting them to treatment with different doses of HSYA. Our results revealed that HSYA could significantly reduce paw swelling, pathological manifestations, and serum cytokine levels in rats with CIA. The HSYA-treated groups showed increased antioxidant enzyme activity in the serum and decreased expression of inflammatory mediators in the synovial tissues. Furthermore, HSYA treatment inhibited extracellular signal-regulated kinase (ERK) signalling pathway activation. Notably, the highest dose of HSYA (20 mg/kg) exhibited the best effects against RA symptoms. Therefore, our findings suggest that HSYA alleviates the inflammatory response and synovial damage in rats with CIA by inhibiting the ERK signalling pathway.

The substance basis of Poria ameliorates hypothyroidism other than hyperthyroidism based on proteomics and metabolomics.

Integrated metabolomics and proteomics analysis was carried out to study the effects of Poria and its split components (volatile oil, triterpenoid, oligosaccharide, amino acid, and crude polysaccharide) on rats of normal physiological model, hyperthyroidism model, and hypothyroidism model to explore the substance basis of Poria for hypothyroidism from the perspective of a holistic view in substance and energy metalism. The key pathways regulating substance and energy metabolism were screened, encompassing tricarboxylic acid cycle pathway, glycolysis/ gluconeogenesis pathways, biosynthesis of amino acid pathway, fatty acid biosynthesis pathway, pentose phosphate pathway, peroxisome proliferator-activated receptors pathway, etc Poria and its split components showed promoting effects on substance and energy metabolism in normal model, while showed amelioration effects on hypothyroidism model at different degrees, and had no significant improvement effects on hyperthyroidism in rats. Volatile oil, triterpenoid, and crude polysaccharide from Poria were regarded as substance basis of Poria ameliorating hypothyroidism other than hyperthyroidism. This work also revealed the feasibility of metabolomics and proteomics analysis to elucidate the effective substance basis of traditional Chinese medicine from a new viewpoint based on its effects on substance and energy metabolism.

The characteristics of ginsenosides and oligosaccharides in mountain- and garden-cultivated ginseng.

BACKGROUND: The present study aimed to explore the chemical characteristics of mountainous forest cultivated ginseng (MFCG) and garden ginseng (GG) with respect to their ginsenosides and oligosaccharides. METHODS: A high-performance liquid chromatography with diode-array detection-evaporative light-scattering detection technique was adopted to investigate the ginseosides and oligosaccharides of GG and MFCG. RESULTS: The features of ginsenosides showed Rg1/Re in different parts of GG and MFCG: main root > lateral root > fibrous root, as well as Rg1/Re in the main root: MFCG > GG, indicating that the Rg1/Re is related to age of the ginseng. In most cases, Rg1/Re < 1 in entire GG and Rg1/Re > 1 in entire MFCG. In addition, the ratio of protopanaxadiol/protopanaxatriol in main root of GG is approximately 1 and, in the main roots of MFCG, the ratio is approximately 2 and, furthermore, Ro/Rb1 of MFCG is lower than that of GG. Analysis of oligosaccharides showed that GG mainly contained sucrose and MFCG mainly contained sucrose and maltose, and the ratio of sucrose to maltose was at least more than 4:1 in GG and less than 4:1 in MFCG in most cases, indicating the characteristics of oligosaccharides of MFCG are primarily affected by its growing environment. The results also showed that ginsenoside Re is most probably the biosynthetic precursor of ginsenoside Rg1 (i.e. Re was synthesized first and then transformed to Rg1 in vivo). CONCLUSION: The characteristics of Rg1/Re and higher maltose can be regarded as one of the characteristics of high quality MFCG, and these characteristics are related to a higher age and the cultivation environment of ginseng. The formation mechanism of these characteristics for GG and MFGG is also discussed. As far as we know, the present study is the first to determine the difference of Rg1/Re and oligosaccharides between MFCG and GG and this provides a reference for the quality control criterion of GG and MFCG. © 2020 Society of Chemical Industry.

Poria ameliorates the side effects of rhubarb in pair treatment.

To investigate the effect of Poria and effective constituents on gastrointestinal injury animals in the area of the side effects which caused by Rhubarb. Mice were administered i.g. with Rhubarb until the induction of diarrhea followed by gastrointestinal injury. The gastrointestinal injured mice were treated with high, medium and low doses of poria water extract and it's subfractions for 5 days. All indexes were determined to evaluate the action of poria in the pair treatment. The results showed that the higher dose of poria water decoction was discovered to be the most effective dose to treat gastrointestinal injury induced by rhubarb. Body weight, thymus and spleen indexes, the small intestinal propulsion rate and D-xylose absorption in mice with diarrhea and intestinal injury were analyzed to reveal the significant difference with the model group (P<0.01). EAF (Ethyl Acetate Fraction), PEF (Petroleum Ether Fraction) and CPF (Crude Polysaccharide Fraction) not only increase the levels of AMS, GAS and VIP significantly but also ameliorate diarrhea and intestinal injury situation compared with the model group (P<0.01). EAF, PEF and CPF were the most effective components to alleviate diarrhea and gastrointestinal injury induced by rhubarb.

Mechanism Investigation of Tagetes patula L. against Chronic Nonbacterial Prostatitis by Metabolomics and Network Pharmacology.

The major objective of this study was to investigate the anti-chronic nonbacterial prostatitis (CNP) mechanism of T. patula by metabolomics and network pharmacology. The study demonstrated that the flavonoids and polysaccharides of T. patula could alleviate prostatitis by improving the level of DHT, reducing the secretion of PSA and TNF-α. Besides, both could enhance Na+/K+-ATPase activity, decrease the O2 consumption, CO2 production, heat production, energy expenditure of rats and promote respiratory exchange ratio of rats. Up to 28 potential biomarkers and 8 key metabolic pathways related to the treatment of CNP were elucidated by the metabolomics analysis, including phenylalanine metabolism, taurine and hypotaurine metabolism, tryptophan metabolism etc. Network pharmacology prediction also reflected the potential mechanism was associated with tryptophan metabolism and energy pathway. Generally, the potential anti-CNP mechanism of flavonoids and polysaccharides of T. patula might be through reducing the expression of inflammation factors, adjusting the level of hormone and regulating the amino acid metabolism, energy metabolism and glucose and lipid metabolism.

Chemical Constituents of Stems and Leaves of Tagetespatula L. and Its Fingerprint.

Tagetespatula L. is a widely cultivated herbal medicinal plant in China and other countries. In this study, two new 2, 3-dihydrobenzofuran glucosides (1, 2) and fourteen known metabolites (3-16) were isolated from the stems and leaves of T. patula (SLT). The chemical structures of the isolated compounds were characterized comprehensively based on one- and two-dimensional NMR spectroscopy and high resolution mass spectrometry. Absolute configurations of compounds 1 and 2 were determined by ECD calculations. Compounds 1 and 2 exhibited moderate in vitro inhibitory activities against human gastric cancer cell lines (AGS) with IC50 values of 41.20 µmol/L and 30.43 µmol/L, respectively. The fingerprint profiles of stems and leaves of T. patula with three color types of flowers (Janie Yellow Bright, Jinmen Orange, Shouyao Red and Yellow color) were established by high-performance liquid chromatography (HPLC). Ten different batches of stems and leaves were examined as follow: Shouyao Red and Yellow color (1, 2, 3), Janie Yellow Bright (4, 5, 6, 7) and Jinmen Orange (8, 9, 10). Twenty-two common peaks were identified with similarity values ranging from 0.910 to 0.977. Meanwhile, the average peak area of SLT in the three types of flowers was different and it was the highest in Janie Yellow Bright.

Arctigenin Attenuates Learning and Memory Deficits through PI3k/Akt/GSK-3ß Pathway Reducing Tau Hyperphosphorylation in Aß-Induced AD Mice.

Arctigenin is a phenylpropanoid dibenzylbutyrolactone lignan compound possessing antitumor, anti-inflammatory, anti-influenza, antioxidant, antibacterial, and hypoglycaemic activities. Our previous study demonstrated that arctigenin exerts neuroprotective effects both in vitro and in vivo in a Parkinson's disease model. However, the exact mechanism through which arctigenin improves amyloid beta-induced memory impairment by inhibiting the production of the hyperphosphorylated tau protein is unknown. Amyloid ß1-42 was slowly administered via the intracerebroventricular route in a volume of 3 µL (≈ 410 pmmol/mouse) to mice. The mice were administered arctigenin (10, 40, or 150 mg/kg) or vehicle starting from the second day after amyloid ß1-42 injection to the end of the experiment. Behavioural tests were performed from days 9 to 15. On day 16 after the intracerebroventricular administration of amyloid ß1-42, the mice were sacrificed for biochemical analysis. Arctigenin (10-150 mg/kg) significantly attenuated the impairment of spontaneous alternation behaviours in the Y-maze task, decreased the escape latency in the Morris water maze test, and increased the swimming times and swimming distances to the platform located in the probe test. Arctigenin attenuated the level of phosphorylated tau at the Thr-181, Thr-231, and Ser-404 sites in the hippocampus, and increased the phosphorylation levels of phosphatidylinositol-3-kinase, threonine/serine protein kinase B, and glycogen synthase kinase-3ß. Arctigenin effectively provides protection against learning and memory deficits and in inhibits hyperphosphorylated tau protein expression in the hippocampus. The possible mechanism may occur via the phosphatidylinositol-3-kinase/protein kinase B-dependent glycogen synthase kinase-3ß signalling pathway.

Evaluation of anti-sepsis activity by compounds with high affinity to lipid a from HuanglianJiedu decoction.

CONTEXT: HuanglianJiedu decoction (HJD) is a classic prescription for heat-clearing away and detoxifying, which is used for the clinical treatment of sepsis, due to sepsis refers to the systemic inflammatory response induced by infection in western medicine, and infection belongs to the category of poison-heat syndrome in traditional Chinese medicine. OBJECTIVES: Previous study had elucidated the effective components from HJD with high affinity to lipid A, which can generate the release of pro-inflammatory-cytokines, resulting in sepsis. Now the anti-sepsis activities of these compounds were evaluated. MATERIALS AND METHODS: Immunofluorescence, immunohistochemical staining, ELISA and MTT methods were used to evaluated these compounds. RESULTS: Immunofluorescence analysis evaluated the effects of compounds on the binding of FITC-LPS to RAW264.7 cells, and showed the fluorescence intensity was significant attenuated in geniposides, palmatine, baicalin and berberine groups (64 and 128 µg/mL) compared with model group (p < 0.05), which showed these compounds inhibit the combination of LPS with receptor of cells; immunohistochemical staining and ELISA method showed the TLR4 receptor expression, IL-6 and TNF-α levels were significant decreased in the groups treated with compounds, indicating that geniposides, baicalin, palmatine and berberine can play the role of anti-sepsis by inhibiting the expression of TLR4, the releasing of IL-6 and TNF-α; MTT assay showed that palmatine and berberine had a weak effect on cell viability, while others not, indicating that the compounds have protective activity. DISCUSSION AND CONCLUSIONS: It could be concluded the high affinity binding between these compounds and lipid A may be an important basis for its anti-LPS activity in vitro.

Metabolomics analysis of anaphylactoid reaction reveals its mechanism in a rat model.

BACKGROUND: Anaphylactoid reactions, accounting for more than 77% of all immune-mediated immediate hypersensitivity reactions, have become a serious threat to public health, but their effect mechanism is not clear and diagnostic tests are limited. Comprehensive metabolite analysis may reveal the anaphylactoid effect mechanism systematically and provide reference for future diagnostic purposes. METHODS: Plasma from Brown Norway rats given intravenous injection of saline, compound 48/80 (2.5 mL/kg) or ovalbumin (20 mL/kg) in 20 s for the first time was used to study the effect mechanism of anaphylactoid reactions through metabolomics (UPLC-qTOF-MS/MS). Metabolomics integrated with proteomics data were used to analyze the anaphylactoid pathways by MetaboAnalyst followed by integrated pathway analysis. RESULTS: Thirty metabolites were identified through the METLIN database by MS/MS and 18 of them were confirmed by authentic standards. The results showed that adenosine, histamine, N-acetylhistamine, N(α)-γ-glutamylhistamine, malate and xanthine are important indices for anaphylactoid reactions. It could be concluded that the effect mechanism is mainly composed of histidine metabolism, arachidonic acid metabolism, energy metabolism, purine metabolism and other small molecules through 30 metabolites. Multiple linear regression analysis indicated that not only histamine but also N(α)-γ-glutamylhistamine and arachidonic acid could be used to evaluate anaphylactoid symptoms of animals. Furthermore, the citrate cycle, histidine metabolism and arachidonic acid metabolism could be the main pathways of anaphylactoid reactions as determined by MetaboAnalyst. CONCLUSION: The results may provide a reference to improve diagnostic accuracy and predict and monitor treatment efficacy in anaphylactoid reactions in the clinical setting.

Ardipusilloside-I stimulates gastrointestinal motility and phosphorylation of smooth muscle myosin by myosin light chain kinase.

Ardipusilloside-I is a natural triterpenoid saponin, which was isolated from Ardisia pusilla A. DC. The aim of the study was to evaluate the stimulation of ardipusilloside-I on gastrointestinal motility in vitro and in vivo. The experiment of smooth muscle contraction directly monitored the contractions of the isolated jejunal segment (IJS) in different contractile states, and the effects of ardipusilloside-I on myosin were measured in the presence of Ca2+-calmodulin using the activities of 20 kDa myosin light chain (MLC20) phosphorylation and myosin Mg2+-ATPase. The effects of ardipusilloside-I on gastro emptying and intestinal transit in constipation-predominant rats were observed, and the MLCK expression in jejuna of constipated rats was determined by western blot. The results showed that, ardipusilloside-I increased the contractility of IJS in a dose-dependent manner and reversed the low contractile state (LCS) of IJS induced by low Ca2+, adrenaline, and atropine respectively. There were synergistic effects on contractivity of IJS between ardipusilloside-I and ACh, high Ca2+, and histamine, respectively. Ardipusilloside-I could stimulate the phosphorylation of MLC20 and Mg2+-ATPase activities of Ca2+- dependent phosphorylated myosin. Ardipusilloside-I also stimulated the gastric emptying and intestinal transit in normal and constipated rats in vivo, respectively, and increased the MLCK expression in the jejuna of constipation-predominant rats. Briefly, the findings demonstrated that ardipusilloside-I could effectively excite gastrointestinal motility in vitro and in vivo.

All of the isolated compounds were assayed for the promoting proliferation of skin fibroblasts cell (ESF-1) and compounds 4 and 7 (5 µM) significantly stimulated the proliferation of ESF-1 cells.

The evaluation and optimization of animal model for anaphylactoid reaction induced by injections.

BACKGROUND: Recent research indicates that injections inducing unwanted anaphylactoid reactions occur frequently in a clinical setting. In this paper, we explored anaphylactoid reactions trends in animal models following ginsenosides injections. METHODS: Our anaphylactoid animal model was optimized by comparing reactions between BN rats, SD rats, guinea pigs and ICR mice to first intravenous exposure to standard compounds including ovalbumin (OVA), tannic acid (TA), Tween 80 (T80), bovine serum albumin (BSA) and Compound 48/80 (C48/80), Shengmai injection (SMI) and Xuesaitong injection (XSTI) which contains ginsenosides, respectively. The anaphylactoid symptoms were documented and the plasma levels of histamine were assessed. Subsequently, the IgE levels and total complement activity (CH50) were determined to further explore the mechanisms underlying the observed anaphylactoid reactions on the optimized animal model. RESULTS: We observed that BN rats and guinea pigs exhibited particularly exacerbated symptoms after administration of OVA, T80, TA, SMI and XSTI. Regarding histamine levels, we observed that BN rats were more sensitive to TA and XSTI, guinea pigs were more sensitive to OVA, T80 and SMI, and SD rats were more sensitive to C48/80. According to both anaphylactoid symptom scores and histamine secretion rates, BN rats, in particular, were found to be more sensitive to OVA, T80, TA, SMI and XSTI. Noteworthy however, the four rodents showed significantly weaker anaphylactoid reactions after administration of BSA. CONCLUSION: BN rats were more suitable for comprehensive evaluation of anaphylatoid reactions following injections; both IgE levels and CH50 could be used as auxiliary mediators for the assessment of anaphylactoid reactions.

[Advance and prospect in studies on anaphylactoid reaction of traditional Chinese medicine injections].

Because of the rapid action and high bioavailability, traditional Chinese medicine injections (TCMIs) had been widely used in clinical critical field. In recent years, with the increasing reports of clinical adverse reaction, more and more attention was paid to them, and acute allergic reaction was the main adverse reaction. Acute allergic reaction included type-I anaphylaxis reaction and anaphylactoid reaction, the latter had been found in a variety of TCMIs and accounted for 77% of adverse reaction. But the mechanism of anaphylactoid reaction was not completely understood, the standard animal model for TCMIs was not established, and the technical guidance for anaphylactoid reaction was not formulated. Thus the three aspects included mechanism, evaluation index and evaluation methods of TCMIs for anaphylactoid were reviewed. Five ways including direct stimulating pathway, complement pathway, coagulation pathway, kallikrein-kinin pathway and acute allergic pathway were the main mechanism of anaphylactoid reaction; whole animal model and cell model were the main evaluation methods; the occurrence index and effect index were reviewed for the evaluation index analysis.

Protective effect of arctigenin against MPP+ and MPTP-induced neurotoxicity.

The potential protective effects of arctigenin on 1-methyl-4-phenylpyridinium ion and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyride-induced neurotoxicity were examined, and the results indicated that arctigenin could improve the movement behaviors and upregulate dopamine and γ-aminobutyric acid levels in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyride-induced neurotoxicity mouse model. A further in vitro experiment showed that the pretreatment with arctigenin on cultured human neuroblastoma SH-SY5Y cells could obviously attenuate the decrease of cell survival rates caused by treatment with 1-methyl-4-phenylpyridinium ion by way of acting against cell apoptosis through the decrease of Bax/Bcl-2 and caspase-3, and by antioxidative action through reduction of the surplus reactive oxygen species production and downregulation of mitochondrial membrane potential. It is for the first time that a neuroprotective activity of arctigenin in both in vitro and in vivo experiments was reported, enlightening that arctigenin could be useful as a potential therapeutic agent for Parkinson's disease.

[Triterpenes constituents from male flowers of Eucommia ulmoides].

Nine triterpenes compounds were isolated from the male flowers of Eucommia ulmoides by recrystallization and chromatographic techniques over silica gel, Sephadex LH-20, and RP-18 gel. Their chemical structures were identified on the basis of spectral analysis and as 3-oxo-12-en-ursane-28-O-α-L-arabinofuranosyl (1 --> 6) -ß-D-glucopyranoside (1), 2α, 3ß-dihydroxyurs-12-en-28-oic acid(28 --> 1) -ß-D-glucopyranosyl ester (2), ursolic acid (3), α-amyrin (4), uvaol (5), ursolic acid acetate (6), 3-O-acetate oleanoic acid (7), betulinic acid (8), and betulinol (9). Compound 1 was a new compound, and compounds 2, 4-7 were isolated from the Eucommiu genus for the first time. Cytotoxic activity was tested for all the compounds against K562 and HepG2 cells. The results showed that only compound 3, exhibited cytotoxic activity.

Anti-prostate cancer mechanism of black ginseng during the "nine steaming and nine sun-drying" process based on HPLC analysis combined with vector space network pharmacology.

HPLC analysis determined six small-molecule organic acids, maltol, 5-hydroxymethylfurfural (5-HMF), 17 ginsenosides, four oligosaccharides, and 20 amino acids in black ginseng samples with different processing times. Based on the content determination results, the differential ingredients in the processing of black ginseng were screened by multivariate statistical analysis. Network pharmacological methods obtained the core targets and pathways of the above ingredients against prostate cancer. Finally, the entropy weight method was used to assign values to the above ingredients, targets, and pathways, and the vector space network pharmacology method was established to study the anti-prostate cancer mechanism of black ginseng in the process of "nine steaming and nine sun-drying". Based on principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA), fructose, glucose, dencichin, glutamate, ginsenoside 20 (S)-Rg3, 20 (R)-Rg3, 20 (S)-Rh2, Rg1, Re, and Rc were the main differential ingredients in various steaming and sun-drying cycle periods of black ginseng. The results of vector space network pharmacology showed that the main reason for the change in the anti-prostate cancer pathway of black ginseng with the number of steaming and sun-drying was the different regulatory ability of black ginseng on the PI3K-Akt signaling pathway and chemical carcinogenesis-receptor activation pathway. It gave researchers a fresh perspective for exploring the anti-prostate cancer active components of black ginseng and the change in the mechanism of the effect of traditional Chinese medicine in processing.
