Metabolomics analysis of Ligustri Lucidi Fructus at different harvest times during the whole growing period based on ultra-high-performance liquid chromatography with mass spectrometry.

After medicinal market research, it was found that the harvest time of Ligustri Lucidi Fructus (LLF) was chaotic in practice. In order to determine the optimal harvest period of LLF to ensure its pharmacological activity, metabolomics analysis of LLF at different harvest times based on ultra-high-performance liquid chromatography-triple quadrupole-(linear ion trap)-tandem mass spectrometry was established. In this study, 166 differential metabolites (DMs) in 448 metabolites at different harvest times were screened out based on variable importance in projection value, and among them, 94 DMs with regular trends of change in relative content (59 increased and 35 decreased with the growth period) were chosen to further research. The result of the multivariate statistical analysis showed that November was the optimal harvest period of LLF. Additionally, 10-hydroxyligustroside, oleoside 11-methyl ester, and salidroside were screened out to be used as the evaluation indicators of immature LLF, while specnuezhenide, nuezhenoside G13, and neonuezhenide were the evaluation indicators of mature LLF. This study provides fundamental insight for metabolite identification and proposes the best harvest period of LLF to avoid confusion in the medicinal market.

Simultaneous determination and quality evaluation of 16 compounds in Ligustri Lucidi Fructus covering different regions and processed products using ultra-high-performance liquid chromatography-mass spectrometry.

A quantitative analysis method and a chemical pattern recognition method were developed to evaluate raw Ligustri Lucidi Fructus (LLF) from different regions and different processed products. In this study, a comprehensive strategy using ultra-high-performance liquid chromatography-mass spectrometry quantitative analysis method was established for the simultaneous determination of 16 components in 47 batches of LLF covering 19 regions belonging to 8 provinces and 24 batches of different processed products (steamed LLF without auxiliary material, wine-steamed LLF, salt-steamed LLF, and vinegar-steamed LLF). The results of this study indicated that the proposed method was reliable and accurate for the rapid analysis proved by detection limit, quantification limit, precision, and accuracy. Furthermore, principal component analysis and hierarchical cluster analysis were employed to analyze the experimental data, showing that the best-quality samples of 47 batches of raw LLF were S47 (Lantian, Shaanxi), S39 (Pingyang-2, Shandong), S38 (Pingyang-1, Shandong), and S45 (Lingbao, Henan), whereas the worst-quality samples were S7-S16 (Huzhou, Zhejiang). In 24 batches of processed products, the best-quality samples were S48 (salt steamed 2 h), S60 (wine steamed 2 h), and S61 (wine steamed 4 h). Meanwhile, the heat map showed that the contents of triterpenoid saponins, including C16 (ursolic acid), C15 (oleanic acid), and C14 (maslinic acid), were higher than those of other compounds in 71 batches of samples. These results suggested that the quality of raw LLF in the central and northern regions was better than that in the southern regions, and regarding the processed products, different auxiliary materials had little effect on the quality of LLF, but steaming time of 2 h was appropriate. Briefly, this study proposed a multiparameter quantitative analysis method for the overall quality control of raw LLF samples covering different regions in China and different processed LLF.

[Virtual screening and antiepileptic activity evaluation of COX-2 inhibitory components in Trachelospermi Caulisetfolium].

This study investigated the potential active components against cyclooxygenase-2(COX-2) from Trachelospermi Caulisetfolium and explored the pharmacodynamic material basis.A pharmacophore-based virtual screening method was adopted to establish a COX-2 ligands-based HipHop pharmacophore model on the basis of the information on compounds with COX-2 inhibitory activity reported in published research articles.The reported components in Trachelospermi Caulisetfolium were collected to establish the compound library and matched with the pharmacophores.Subsequently, the matched small molecule compounds underwent molecular docking with COX-2 targets(PDB ID: 3 LN1), and the interaction of potential active monomers and COX-2 was further explored by molecular dynamics.The antiepileptic effect of active monomer arctigenin(15) was determined based on the pentylenetetrazole(PTZ)-induced seizure model, and its modulatory effect on the COX-2 level was evaluated.A compound library containing 118 chemical constituents in Trachelospermi Caulisetfolium was established by literature retrieval.The preferred pharmacophore 04 was selected through test set verification for virtual screening of the compound library of Trachelospermi Caulisetfolium.After matching, six potential constituents with COX-2 inhibitory activity were obtained.The interaction of five compounds with COX-2 and COX-1 was analyzed by molecular docking, and 10 ns molecular dynamics was performed on two compounds.Compound 15 could prolong the latent time of PTZ-induced seizures at medium and high doses, improve the anxiety-and depression-like behaviors induced by PTZ, reduce the expression level of COX-2, and decrease the number of COX-2 immuno-posi-tive cells in the hippocampal CA1 region.The results showed that it was reasonable to investigate the components in Trachelospermi Caulisetfolium with COX-2 inhibitory activity based on virtual screening and activity evaluation.

Advances in Anti-Osteoporosis Polysaccharides Derived from Medicinal Herbs and Other Edible Substances.

Osteoporosis is a common metabolic bone disease, and treatment is required for the prevention of low bone mass, deterioration of microstructural bone tissue, and fragility fractures. Osteoporosis therapy includes calcium, vitamin D, and drugs with antiresorptive or anabolic action on the bone. Therapy for osteoporosis does not include taking non-steroidal anti-inflammatory drugs (NSAID), but pain associated with osteoporotic fractures can be treated by taking non-steroidal anti-inflammatory drugs (NSAID). Recently, polysaccharides extracted from medicinal herbs and edible substances (PsMHES) have attracted attention on account of their safety and promising anti-osteoporosis effects, whereas a systematic review about their potential in anti-osteoporosis is vacant to date. Herein, we reviewed the recent progress of PsMHES with anti-osteoporosis activities, looking to introduce the advances in the various pharmacological mechanisms and targets involved in the anti-osteoporosis effects, extraction methods, main mechanism involved in Wnt/[Formula: see text]-catenin pathways and RANKL (Receptor Activator for NF[Formula: see text]B ligand or TNFSF25) pathways, and Structure-Activity Relationships (SAR) analysis of PsMHES. Typical herbs likeAchyranthes bidentate and Morinda officinalis used for the treatment of osteoporosis are introduced; their traditional uses in traditional Chinese medicine (TCM) are discussed in this paper as well. This review will help to the recognition of the value of PsMHES in anti-osteoporosis and provide guidance for the research and development of new anti-osteoporosis agents in clinic.

Local and traditional uses, phytochemistry, and pharmacology of Sophora japonica L.: A review.

ETHNOPHARMACOLOGICAL RELEVANCE: Sophora japonica (Fabaceae), also known as Huai (Chinese: ), is a medium-sized deciduous tree commonly found in China, Japan, Korea, Vietnam, and other countries. The use of this plant has been recorded in classical medicinal treatises of ancient China, and it is currently recorded in both the Chinese Pharmacopoeia and European Pharmacopoeia. The flower buds and fruits of S. japonica, also known as Flos Sophorae Immaturus and Fructus Sophorae in China, are most commonly used in Asia (especially in China) to treat hemorrhoids, hematochezia, hematuria, hematemesis, hemorrhinia, uterine or intestinal hemorrhage, arteriosclerosis, headache, hypertension, dysentery, dizziness, and pyoderma. To discuss feasible trends for further research on S. japonica, this review highlights the botany, ethnopharmacology, phytochemistry, biological activities, and toxicology of S. japonica based on studies published in the last six decades. MATERIALS AND METHODS: Information on the S. japonica was collected from major scientific databases (SciFinder, PubMed, Elsevier, SpringerLink, Web of Science, Google Scholar, Medline Plus, China Knowledge Resource Integrated (CNKI), and "Da Yi Yi Xue Sou Suo (http://www.dayi100.com/login.jsp)" for publications between 1957 and 2015 on S. japonica. Information was also obtained from local classic herbal literature, government reports, conference papers, as well as PhD and MSc dissertations. RESULTS: Approximately 153 chemical compounds, including flavonoids, isoflavonoids, triterpenes, alkaloids, polysaccharides, amino acids, and other compounds, have been isolated from the leaves, branches, flowers, buds, pericarps, and/or fruits of S. japonica. Among these compounds, several flavonoids and isoflavonoids comprise the active constituents of S. japonica, which exhibit a wide range of biological activities in vitro and in vivo such as anti-inflammatory, antibacterial, antiviral, anti-osteoporotic, antioxidant, radical scavenging, antihyperglycemic, antiobesity, antitumor, and hemostatic effects. Furthermore, flavonoids and isoflavonoids can be used as quality control markers for quality identification and evaluation of medicinal materials and their preparations. Information on evaluating the safety of S. japonica is very limited, so further study is required. To enable safer, more effective, and controllable therapeutic preparations, more in-depth information is urgently needed on the quality control, toxicology data, and clinical value of crude extract and active compounds of S. japonica. CONCLUSIONS: S. japonica has long been used in traditional Chinese medicine (TCM) due to its wide range of biological activities, and is administered orally. Phytochemical and pharmacological studies of S. japonica have increased in the past few years, and the extract and active components of this plant can be used to develop new drugs based on their traditional application as well as their biological activities. Therefore, this review on the ethnopharmacology, phytochemistry, biological activities, and toxicity of S. japonica offers promising data for further studies as well as the commercial exploitation of this traditional medicine.
