[Prediction of quality markers and medicinal value of sea buckthorn leaves based on network pharmacology, content determination, and activity evaluation].

The leaves of sea buckthorn(Hippophae rhamnoides), considered as common food raw materials, have records of medicinal use and diverse pharmacological activities, showing a potential medicinal value. However, the active substances in the sea buckthorn leaves and their mechanisms of action remain unclear. In addition, due to the extensive source and large variety variations, the quality evaluation criteria of sea buckthorn leaves remain to be developed. To solve the problems, this study predicted the main active components, core targets, key pathways, and potential pharmacological effects of sea buckthorn leaves by network pharmacology and molecular docking. Furthermore, ultra-performance liquid chromatography with diode-array detection(UPLC-DAD) was employed to determine the content of active components and establish the chemical fingerprint, on the basis of which the quality markers of sea buckthorn leaves were predicted and then verified by the enzyme activity inhibition method. The results indicated that sea buckthorn leaves had potential therapeutic effects on a variety of digestive tract diseases, metabolic diseases, tumors, and autoimmune diseases, which were consistent with the ancient records and the results of modern pharmacological studies. The core targets of sea buckthorn leaves included PTPN11, AKT1, PIK3R1, ESR1, and SRC, which were mainly involved in the PI3K-AKT, MAPK, and HIF-1 signaling pathways. In conclusion, the active components of sea buckthorn leaves are associated with the rich flavonoids and tannins, among which quercitrin, narcissoside, and ellagic acid can be used as the quality markers of sea buckthorn leaves. The findings provide a reference for the quality control and further development and utilization of sea buckthorn leaves as medicinal materials.

[Degradation kinetics of ß-nicotinamide mononucleotide based on reliable HPLC quantitative method].

To explore the stability characteristics of ß-nicotinamide mononucleotide(NMN) and provide data support for NMN production, preparation, and related product development, this study established a simple HPLC content determination method for NMN in simple substrate and investigated the degradation behavior, degradation products, and degradation kinetics of NMN under various chemical, physical, and biological conditions. The HPLC method employed a Welch Xtimate AQ-C_(18) column(4.6 mm×250 mm, 5 µm), a detection wavelength of 266 nm, a column temperature of 30 ℃, a flow rate of 1.0 mL·min~(-1), an injection volume of 5 µL, and a mobile phase consisting of methanol(A) and a 10 mmol·L~(-1) ammonium formate aqueous solution(B) with a gradient elution(0-6.7 min, 0-4% A; 6.7-13 min, 4%-18% A; 13-14.2 min, 18% A; 14.2-15 min, 18%-0 A; 15-22 min, 0 A). This method provided good separation between NMN and potential impurities and degradation products, and had a wide linear range, short analysis time, good durability, high accuracy, an average sample recovery rate of 98.71%, and an RSD of 1.2%. The instrument precision had an RSD of 0.26%, and the linearity within the examined range was excellent(R~2≥0.999 9). This method can be applied for NMN content determination in simple substrate. The degradation process of NMN in aqueous solution followed apparent first-order kinetics, with the degradation rate primarily influenced by high temperature and pH. NMN was more stable in low-temperature, neutral, or weakly acidic/alkaline environments. Strong acids or strong alkalis could accelerate its degradation, and its degradation rate was less affected by pepsin and trypsin. In an aqueous solution at room temperature, it followed the kinetic equation lg C_t=0.005 7t + 4.817 2, with t_(0.9) and t_(1/2) values of 95.58, 860.26 h, respectively. The results suggest that pH and temperature are the main factors affecting the stability of NMN in aqueous solution, and low temperature, moisture protection, and a weakly acidic environment are more conducive to the storage and application of NMN and its products.

A Global Analysis of Alternative Splicing of Dichocarpum Medicinal Plants, Ranunculales.

Background: The multiple isoforms are often generated from a single gene via Alternative Splicing (AS) in plants, and the functional diversity of the plant genome is significantly increased. Despite well-studied gene functions, the specific functions of isoforms are little known, therefore, the accurate prediction of isoform functions is exceedingly wanted. Methods: Here we perform the first global analysis of AS of Dichocarpum, a medicinal genus of Ranunculales, by utilizing full-length transcriptome datasets of five Chinese endemic Dichocarpum taxa. Multiple software were used to identify AS events, the gene function was annotated based on seven databases, and the protein-coding sequence of each AS isoform was translated into an amino acid sequence. The self-developed software DIFFUSE was used to predict the functions of AS isoforms. Results: Among 8,485 genes with AS events, the genes with two isoforms were the most (6,038), followed by those with three isoforms and four isoforms. Retained intron (RI, 551) was predominant among 1,037 AS events, and alternative 3' splice sites and alternative 5' splice sites were second. The software DIFFUSE was effective in predicting functions of Dichocarpum isoforms, which have not been unearthed. When compared with the sequence alignment-based database annotations, DIFFUSE performed better in differentiating isoform functions. The DIFFUSE predictions on the terms GO:0003677 (DNA binding) and GO: 0010333 (terpene synthase activity) agreed with the biological features of transcript isoforms. Conclusion: Numerous AS events were for the first time identified from full-length transcriptome datasets of five Dichocarpum taxa, and functions of AS isoforms were successfully predicted by the self-developed software DIFFUSE. The global analysis of Dichocarpum AS events and predicting isoform functions can help understand the metabolic regulations of medicinal taxa and their pharmaceutical explorations.

[Research progress in DIR gene of lignan biosynthesis in medicinal plants].

The active components, mainly derived from secondary metabolites of medicinal plants, are the material basis for the efficacy of medicinal plants. Lignans, the secondary metabolites in plants with high bioactivity, are widely distributed in a variety of plant species, and their antiviral, antitumor, antibacterial, and antioxidant activities have been proved in clinical practice. Generally, lignans are diverse in structures with many chiral centers, and most of them are optically active. The biosynthesis of lignans depends on the oxidative coupling reaction through site selection and stereo selection, which impedes synthesized lignans to form racemates, but makes them in a three-dimensional configuration. Dirigent protein(DIR) plays an important role in guiding location selection and stereo selection of lignans in biosynthesis. In vitro studies on lignan biosynthesis have shown that racemic end products are obtained in the absence of DIR proteins, while the products in a three-dimensional configuration can be yielded in the presence of DIR proteins, indicating that DIR proteins play an asymmetric role in the biosynthesis of plant secondary metabolites. The present study reviewed the biolo-gical significance of DIR protein, the cloning of DIR gene, gene structure, catalytic mechanism, and the research progress in Isatis indigotica, Eucommia ulmoides, Forsythia suspensa, Salvia miltiorrhiza, Panax pseudoginseng var. notoginseng, and Schisandra chinensis, which provides a reference for the follow-up research of DIR gene.

[Withania somnifera: a kind of food-medicine plant popular in world in recent years].

Modern studies have shown that the main chemical components of W. somnifera are withanolides, which have antioxidant, anti-tumor, enhancing immunity, cardiovascular protection, neuroprotection, anti-stress, anti-stress reaction and hypoglycemic activities. Studies on human, animal, mutagenesis, genotoxicity, reproductive toxicity and drug interaction showed that W. somnifera had good safety. Clinical trials have proved that W. somnifera is effective in treating a variety of human diseases. As a famous traditional medicine and modern dietary supplement, it has a high reputation and market in the international health product market, but in China, there is little scientific research, market development, product introduction and application. In this paper, the traditional application, chemical composition, pharmacological activity, safety evaluation and clinical study of the plant were introduced, so as to increase the understanding of the dual use of the plant, and to provide reference for the future introduction of the product, the service to the health of the Chinese people and the promotion of the "double cycle" of the trade of health products between China and the international community.

[Material basis and mechanism of Huangqin Tea in prevention of colorectal cancer based on network pharmacology and molecular docking].

Colorectal cancer is a malignancy with high mortality. Huangqin Tea(HQT) can exert potential preventive and therapeutic effects on colorectal cancer. Flavonoids are the main compounds in HQT, but the pharmacodynamic material basis and mechanism are unclear. Network pharmacology and molecular docking were used to predict and analyze the targets and signaling pathways of HQT in the prevention and treatment of colorectal cancer. The active components of flavonoids in HQT were searched and screened out by literature review and FAFDrugs4. The related targets of active components were predicted by SwissTargetPrediction, STITCH, and TCMSP. Colorectal cancer-related genes were collected from OMIM, TTD, and GeneCards. The common targets were obtained as the potential targets of HQT in the prevention and treatment of colorectal cancer. Metascape was used for GO function enrichment and KEGG pathway enrichment analyses. Cytoscape was used to construct the protein-protein interaction(PPI) network and "component-target-disease-pathway" network to obtained and analyze core targets and key components. AutoDock Vina was used for molecular docking verification of key components and core targets. The results showed that apigenin, luteolin, wogonin, and baicalein were presumedly the key active components in the prevention and treatment of colorectal cancer, and core targets included TP53, AKT1, VEGFA, PIK3 CA, and SRC. The key KEGG signaling pathways mainly involved PI3 K-AKT, AGE-RAGE, p53, NF-κB, Wnt, Hippo, and calcium signaling pathways. Further molecular docking results showed that four key components showed strong hydrogen bonding ability with the five core targets. This study preliminarily reveals the pharmacodynamic material basis and potential mechanism of HQT in the prevention and treatment of colorectal cancer and provides a theoretical and scientific basis for the application of HQT.

[Application and modern research progress of sea buckthorn leaves].

Sea buckthorn(Hippophae rhamnoides) is widely distributed, with abundant resources, a long history of application, and rich nutrition and high medicinal value. Therefore, it has attracted extensive attention from researchers at home and abroad. The focus of attention is mainly on sea buckthorn fruit, but with weak research and development of sea buckthorn leaves. In order to develop and utilize abundant resources of sea buckthorn leaves, this paper systematically reviewed domestic and foreign literatures and summarized the current application, harvesting and processing, chemical constituents and pharmacological activities of sea buckthorn leaves. Sea buckthorn leaves have a wide development and utilization value in food raw materials(like a substituting-for-tea plant), pharmaceutical raw materials and animal feed. Modern studies have shown that the leaves of sea buckthorn are rich in polysaccharides, flavonoids, polyphenols, triterpenes and steroids, as well as vitamins(especially vitamin C), proteins, amino acids and mineral elements. It has various pharmacological effects, such as anti-obesity, hypoglycemia, anti-oxidation, antibacterial, anti-inflammatory and anti-cardiovascular diseases. Domestic and foreign studies have showed that sea buckthorn leaves have important development and utilization prospects, and are worth further study and development.

[A preliminary pharmacophylogenetic study of Solanaceae medicinal plants containing tropane alkaloids].

The Solanaceae plants distributed in China belong to 105 species and 35 varietas of 24 genera. Some medicinal plants of Solanaceae are rich in tropane alkaloids(TAs), which have significant pharmacological activities. In this paper, the geographical distribution, chemical components, traditional therapeutic effect, pharmacological activities, and biosynthetic pathways of TAs in Solanaceous plants were summarized. Besides, the phylogeny of medicinal plants belonging to Solanaceae was visualized by network diagram. Fourteen genera of Solanaceae plants in China contain TAs and have medical records. TAs mainly exist in Datura, Anisodus, Atropa, Physochlaina, and Hyoscyamus. The TAs-containing species were mainly concentrated in Southwest China, and the content of TAs was closely related to plant distribution area and altitude. The Solanaceae plants containing TAs mainly have antispasmodic, analgesic, antiasthmatic, and antitussive effects. Modern pharmacological studies have proved the central sedative, pupil dilating, glandular secretion-inhibiting, and anti-asthma activities of TAs. These pharmacological activities provide a reasonable explanation for the traditional therapeutic efficacy of tropane drugs. In this paper, the geographical distribution, chemical components, traditional therapeutic effect, and modern pharmacological activities of TAs-containing species in Solanaceae were analyzed for the first time. Based on these data, the genetic relationship of TAs-containing Solanaceae species was preliminarily discussed, which provided a scientific basis for the basic research on TAs-containing solanaceous species and was of great significance for the development of natural medicinal plant resources containing TAs.

[Simultaneous rapid detection of ten stilbenes in serum of mice by UPLC-MS/MS].

Stilbenes is a class of natural polyphenols with 1,2-diphenylethylene as the skeleton structure which have structural and active diversity. However, there are fewer studies on their metabolic process, which limits the in-depth research and development of such components. An UPLC-MS/MS method simultaneously determining contents of ten stilbenes was firstly established in this study and applied to study the ten stilbenes of peony seed coats in the serum of C57 mice.Piceatannol was the internal standard, and methanol was used for protein precipitation, UPLC-MS/MS with negative ion mode was used for analysis, and the method was validated.The serum samples were collected and detected after mice being oral administered with 800 mg·kg~(-1) peony seed coat extracts for 8 weeks. The results showed that suffruticosol A, suffruticosol B, suffruticosol C, trans-ε-viniferin, cis-gnetin H, trans-suffruticosol D and trans-gnetin H were detected in serum samples, and the highest is suffruticosol A. The method is simple and quick with high specificity and sensitivity, and it is suitable for quantitative determination of ten stilbenes in the serum of mice.

[Research methods and applications progress on spectrum-effect relationships in study of traditional Chinese medicine].

The application of chemical fingerprint to evaluate the quality of traditional Chinese medicine has been widely accepted and used in many countries. However,only by analyzing the type and content of its chemical components to evaluate the quality of traditional Chinese medicines,the gold standard of quality evaluation by evaluating pharmacodynamic effects is ignored. The study of Chinese medicinal spectrum-effect relationships combining the chemical composition with the pharmacodynamic activity of traditional Chinese medicine,which can evaluate the quality of traditional Chinese medicine from more comprehensive and different angles,has been applied in many fields of traditional Chinese medicine research. This paper mainly summarizes the research methods of the Chinese medicinal spectrum-effect relationships and its application in the field of traditional Chinese medicine study,and provides reference for the research,development and application of the Chinese medicinal spectrum-effect relationships.

The first Taxus rhizosphere microbiome revealed by shotgun metagenomic sequencing.

In the present study, the shotgun high throughput metagenomic sequencing was implemented to globally capture the features of Taxus rhizosphere microbiome. Total reads could be assigned to 6925 species belonging to 113 bacteria phyla and 301 species of nine fungi phyla. For archaea and virus, 263 and 134 species were for the first time identified, respectively. More than 720,000 Unigenes were identified by clean reads assembly. The top five assigned phyla were Actinobacteria (363,941 Unigenes), Proteobacteria (182,053), Acidobacteria (44,527), Ascomycota (fungi; 18,267), and Chloroflexi (15,539). KEGG analysis predicted numerous functional genes; 7101 Unigenes belong to "Xenobiotics biodegradation and metabolism." A total of 12,040 Unigenes involved in defense mechanisms (e.g., xenobiotic metabolism) were annotated by eggNOG. Talaromyces addition could influence not only the diversity and structure of microbial communities of Taxus rhizosphere, but also the relative abundance of functional genes, including metabolic genes, antibiotic resistant genes, and genes involved in pathogen-host interaction, bacterial virulence, and bacterial secretion system. The structure and function of rhizosphere microbiome could be sensitive to non-native microbe addition, which could impact on the pollutant degradation. This study, complementary to the amplicon sequencing, more objectively reflects the native microbiome of Taxus rhizosphere and its response to environmental pressure, and lays a foundation for potential combination of phytoremediation and bioaugmentation.

Functional and Transcriptomic Characterization of a Dye-decolorizing Fungus from Taxus Rhizosphere.

We isolated three laccase-producing fungus strains from Taxus rhizosphere. Myrotheium verrucaria strain DJTU-sh7 had the highest laccase activity of 216.2 U/ml, which was increased to above 300 U/ml after optimization. DJTU-sh7 had the best decolorizing effect for three classes of reactive dyes. The DJTU-sh7-containing fungal consortium displayed the robust decolorizing ability. Both color removal efficiency and chemical oxygen demand were increased in the consortium mediated biotransformation. Transcriptome changes of M. verrucaria elicited by azo dye and phenolic were quantified by the high throughput transcriptome sequencing, and the activities of the selected oxidases and reductases were determined. The possible involvement of oxidases and reductases, especially laccase, aryl alcohol oxidase, and ferric reductase in the biotransformation of dye and phenolic compounds was revealed at both transcriptomic and phenotypic levels. Revealing the transcriptomic mechanisms of fungi in dealing with organic pollutants facilitates the fine-tuned manipulation of strains in developing novel bioremediation and biodegradation strategies.We isolated three laccase-producing fungus strains from Taxus rhizosphere.

[Morphological, microscopic, multiple-component assay and fingerprinting based systematic research on quality evaluation of Moutan Cortex(Paeonia suffruticosa)].

The purpose of this study was to combine morphological, microscopic, UHPLC multiple-component assay and fingerprinting studies in order to evaluate the quality of Moutan Cortex (MC) systematically. The root system of Paeonia suffruticosa was measured to compare the morphological variation and the chemical composition of different grades of MC was discussed according to previous studies. The difference between the main microscopic features of MC powder and the xylem powder is dramatic, the MC powder contains great amount of starch granules and clusters of calcium oxalate, while the xylem powder displays considerable vessels. Interestingly, the growth rings of P. suffruticosa was first reported in the xylem of the root transection, this can help to determine the growth years of the plant. Moreover, through the assay of 16 component, MC produced in Tongling and Bozhou in Anhui province were compared, content of PGG in MC produced in Bozhou was significantly higher than MC produced in Tongling (P<0.01). MC with different growth years, MC with xylem and unprocessed MC and MC decoction pieces were compared respectively by combining the results of 16 compounds assay and fingerprinting. It is proposed that the quality evaluation standard include the assay of paeoniflorin. Above all, the holistic quality difference can be evaluated more comprehensively by combining multiple analytical methods.

Anticancer Chemodiversity of Ranunculaceae Medicinal Plants: Molecular Mechanisms and Functions.

The buttercup family, Ranunculaceae, comprising more than 2,200 species in at least 62 genera, mostly herbs, has long been used in folk medicine and worldwide ethnomedicine since the beginning of human civilization. Various medicinal phytometabolites have been found in Ranunculaceae plants, many of which, such as alkaloids, terpenoids, saponins, and polysaccharides, have shown anti-cancer activities in vitro and in vivo. Most concerns have been raised for two epiphany molecules, the monoterpene thymoquinone and the isoquinoline alkaloid berberine. At least 17 genera have been enriched with anti-cancer phytometabolites. Some Ranunculaceae phytometabolites induce the cell cycle arrest and apoptosis of cancer cells or enhance immune activities, while others inhibit the proliferation, invasion, angiogenesis, and metastasis, or reverse the multi-drug resistance of cancer cells thereby regulating all known hallmarks of cancer. These phytometabolites could exert their anti-cancer activities via multiple signaling pathways. In addition, absorption, distribution, metabolism, and excretion/toxicity properties and structure/activity relationships of some phytometabolites have been revealed assisting in the early drug discovery and development pipelines. However, a comprehensive review of the molecular mechanisms and functions of Ranunculaceae anti-cancer phytometabolites is lacking. Here, we summarize the recent progress of the anti-cancer chemo- and pharmacological diversity of Ranunculaceae medicinal plants, focusing on the emerging molecular machineries and functions of anti-cancer phytometabolites. Gene expression profiling and relevant omics platforms (e.g. genomics, transcriptomics, proteomics, and metabolomics) could reveal differential effects of phytometabolites on the phenotypically heterogeneous cancer cells.

[Influence of different cultivation measures on the content of three free carbohydrates of Codonopsis Radix].

To provide a scientific evidence for the quality control of Codonopsis Radix, a method was established for determining the content of three free carbohydrates of Codonopsis Radix. The developed method showed good linearity. The calibration curves were linear within the range of 2.312 5-18.500 0 µg for sucrose, 1.500 0-12.000 0 µg for glucose, and 2.000 0-16.000 0 µg for fructose, resgectwely. The recoveries varied between 96.31%-101.8%. The method is simple, accurate and reproducible, and can be used for determining the content of sucrose, glucose and fructose of Codonopsis Radix. The results showed that different cultivation measures had an effect on the content of three free carbohydrates of Codonopsis Radix. According to the content of sucrose, using Zhuanggenling>not using Zhuanggenling. While, not pinching, shelving>not pinching, not shelving>pinching, not shelving>pinching, shelving. According to the content of glucose and fructose, not using Zhuanggenling>using Zhuanggenling. While, pinching, shelving>not pinching, not shelving>not pinching, shelving>pinching, not shelving. In consideration of the differences of sweetness and content of the three free carbohydrates in Codonopsis Radix, we recommend that the content of free carbohydrates could be considered as the marker to evaluate the quality of Codonopsis Radix.

[Determination of ten stilbenes and their antioxidant activity of peony seed coat, seed kernel and seed coat extracts].

The seed of tree peony and herbaceous peony contained a variety of stilbenes which possess many pharmacological activities, such as antitumor, anti-inflammatory, allergy and neuraminidase inhibition. In order to develop and use peony seed resources, a simple and sensitive HPLC-DAD was developed for simultaneous determination of 10 stilbenes in peony samples, i.e.,suffruticosol A,suffruticosol B,suffruticosol C,trans-resveratrol,cis-ε-viniferin,trans-ε-viniferin,cis-suffruticosol D,cis-gnetin H,trans-suffruticosol D and trans-gnetin H. At the same time, the scavenging activity of DPPH free radicals was employed to evaluate their antioxidant effect. The results showed that the 10 stilbenes are mainly present in peony seed coat (total content of more than 16.7%) compared to peony seed kernel (total content less than 0.3%), and can be enriched in the extract of peony seed coat (total content of more than 75%) The extract of peony seed coat and 10 stilbenes exhibited significant antioxidant properties. This work provides a foundation for comprehensive utilization of the tree peony and herbaceous peony seed resources.
