The genus Chloranthus has 13 species and 5 varieties in China, which can be found in the southwest and northeast regions. Phytochemical studies on Chloranthus plants have reported a large amount of terpenoids, such as diterpenoids, sesquiterpenoids, and sesquiterpenoid dimers. Their anti-inflammation, anti-tumor, antifungal, antivirus, and neuroprotection activities have been confirmed by previous pharmacological research. Herein, research on the chemical constituents from Chloranthus plants and their biological activities over the five years was summarized to provide scientific basis for the further development and utilization of Chloranthus plants.

It was aimed at exploring the potential pharmacological effects of alkaloids in Sophora alopecuroides by means of network pharmacology in this study. The main alkaloids in S. alopecuroides were collected for analysis of drug properties, prediction of potential targets and screening of signaling pathways. DAVID analysis tool combined with KEGG database was used to annotate and analyze the signaling pathway. The alkaloids-targets-signaling pathways network was built through Cytoscape software. Results showed that 17 alkaloids in S. alopecuroides involved 49 targets (170 times in all) and 22 important signaling pathways. Three nodes in model of network pharmacology were cross-linked, and the metabolic pathways were coordinated and regulated by each other. It indicated that alkaloids in S. alopecuroides may have therapeutic effect on diseases of cancer, metabolic disorder, endocrine system, digestive system, nervous system and so on.

Antithrombus is one of the effective methods to prevent and treat cardiovascular diseases. Based on the theory of traditional Chinese medicine,the author's previous research and relevant literature,it was found that the alkaloids in Houttuynia cordata has potential antithrombotic effect. However,the pharmacological substance basis and antithrombotic mechanism of H. cordata have not been clarified. In this study,molecular docking was used for virtual screening of antithrombotic alkaloids from H. cordata. Seventy alkaloids selected from H. cordata were screened in the docking ligand data-base with teen thrombosis targets with known crystal structures as the receptors. In addition,the small-molecule approved or to be approved drugs of targets from Drug Bank database were set as a positive reference with minimum score(S value) of each target's approved or to be approved drugs as threshold. The Dock module in Molecular Operating Environment(Version 2016) software was applied to screen the potential active compounds which their scores(S value) were lower than the minimum score of reference. At last the mechanism of antithrombotic effect was preliminarily revealed by compared the main active sites of the test alkaloids with original ligands and references. This study provided some useful information to development of antithrombus drugs.

The flower of Hibiscus syriacus has good ornamental and edible-medicinal values.In this study,four samples of two varieties,namely white multiple petals flower and pink multiple petals flower,were selected as test materials.And the optimum extraction conditions,relative molecular weight,monosaccharide composition and antioxidant activity of polysaccharides in flower were investigated.Through single factor experiment and response surface,the optimal extract conditions of polysaccharide were designed as follows:extraction temperature at 96.8℃,ratio of material to liquid of 43.5∶1 m L·g~(-1),extraction time of 3.1 h.Polysaccharides of H.syriacus flowers were analyzed by high performance gel chromatography.The average molecular masses of the 4 polysaccharide samples were1.49×10~5,1.25×10~5,1.01×10~5,1.37×10~5,respectively.Polysaccharides of H.syriacus flowers were mainly composed of glucose,mannose,galactose,rhamnose and arabinose by pre-column derivatization HPLC.The ratio of galactose was the highest in five monosaccharide,and the ratio of galactose to glucose was 1.656-4.496.In addition,crude polysaccharides of H.syriacus flowers showed potential antioxidant activity by 1,1-diphenyl-2-picrylhydrazyl radical(DPPH)assay,total reducing capacity assay and ABTS assay in vitro,and its antioxidant effect showed a good dose-effect relationship with the concentration of crude polysaccharides.Among the tested varieties,polysaccharides of pink multiple petals flower and white multiple petals flower had the same molecular masses and monosaccharides composition,but the antioxidant activity of the polysaccharides of pink multiple petals flower was higher than that of the white flowers.The results of this study can provide a theoretical basis for the application of H.syriacus flower in the field of functional foods.

OBJECTIVE: Carpobrotus edulis (L.) N.E.Br. is a succulent perennial plant native to South Africa and grows invasively in the Mediterranean basin. It is commonly used for the treatment of various diseases, including skin wound healing and regeneration, for which experimental validation is lacking. We therefore evaluated the skin healing properties by testing a C. edulis aqueous leaf extract (CAE) on cell cultures and in enzymatic assays. METHODS: Micro-morphological analysis of leaves was carried out using scanning electron microscopy and light microscopy. Phytochemical features and antioxidant activity of CAE were evaluated by reversed-phase liquid chromatography coupled with diode array detection and electrospray ion trap mass spectrometry (RP-LC-DAD-ESI-MS), and in vitro cell-free assays. Biological activities were evaluated using keratinocytes and fibroblasts, as well as elastase, collagenase, and hyaluronidase. RESULTS: CAE showed high carbohydrates (28.59% ± 0.68%), total phenols ([101.9 ± 6.0] g gallic acid equivalents/kg dry extract [DE]), and flavonoids ([545.9 ± 26.0] g rutin equivalents/kg DE). RP-LC-DAD-ESI-MS revealed the predominant presence of hydroxycinnamic acids (51.96%), followed by tannins (14.82%) and flavonols (11.32%). The extract was not cytotoxic, had a strong and dose-dependent antioxidant activity, and inhibited collagenase (> 90% at 500 µg/mL) and hyaluronidase (100% at 1000 µg/mL). In cell culture experiments, CAE increased wound closure and collagen production, which was consistent with its high polyphenol content. CONCLUSION Our data support the use of the C. edulis for skin care and the treatment of skin problems. Moreover, use of C. edulis for skin care purposes could be an eco-friendly solution to reduce its invasiveness in the environment.

This study aimed to investigate the molecular mechanism and protective effect of total saponins of Panax japonicas (TSPJ) on HepG2 cells apoptosis induced by palmitic acid (PA).The HepG2 cells were cultured , and divided into five groups: the control group, the model group, the high-dose group (50 mg·L⁻¹), the middle-dose group (25 mg·L⁻¹) and the low-dose group (12.5 mg·L⁻¹).The cells of the five groups were cultured continuously for 24 hours. The cell viability was measured with MTT. HepG2 cells apoptosis was detected by Hoechest staining and Annexin V-FITC/PI staining. The protein expressions of BCL-2, CHOP and TLR4 were measured with western blotting and flow cytometry analysis. The mRNA expressions of TNF-α, IL-1β, BCL-2, CHOP and GAPDH were measured with RT-PCR. The results suggested that compared with the control group, the number of HepG2 cells of the model group were reduced significantly (<0.01), while the number of apoptotic HepG2 cells were increased. Compared with the model group, the number of HepG2 cells of the high-dose group and the middle-dose group were increased significantly (<0.01), whereas the number of apoptotic HepG2 cells were reduced. Compared with the control group, TNF-α, IL-1β and CHOP mRNA expressions and CHOP and TLR4 protein expressions in the model group were significantly up-regulated (<0.01), while BCL-2 protein and mRNA expressions in the model group were significantly decreased (<0.01). Compared with the model group, TNF-α, IL-1β and CHOP mRNA expressions and CHOP and TLR4 protein expressions in the high-dose group were significantly decreased (<0.01), while BCL-2 protein and mRNA expressions in the high-dose group were significantly up-regulated (<0.01).In conclusion, TSPJ can reduce inflammation and apoptosis induced by palmitic acid, with a certain protective effect on liver cells.
