The active components,targets,and pathways of Euphorbia fischeriana Steud.-Jujubae Fructus in treating hepatocirrhosis and the mechanism of action were explored by means of network pharmacology.Firstly,the active components and related targets of Jujubae Fructus were screened by TCMSP database and standardized by Uniprot database.The compounds of Euphorbia fischeriana Steud.were obtained by searching the literature and finally screened by PubChem database,Swiss ADME,and SwissTargetPrediction.Hepatocirrhosis targets were obtained through Genecards database,PPI network analysis was conducted on common targets of Euphorbia fischeriana Steud.-Jujubae Fructus and hepatocirrhosis by using String database,GO enrichment analysis and KEGG pathway enrichment analysis was conducted through Metascape database by using intersection targets of Euphorbia fischeriana Steud.-Jujubae Fructus and hepatocirrhosis,and the results were drawn by using Weishengxin online drawing platform.Then,the network of drug-compound-target-pathway was constructed by the software of Cytoscape3.8.0.Finally,the above results were verified by molecular docking.47 active compounds from Euphorbia fischeriana Steud.-Jujubae Fructus were screened out,which had 38 common targets,162 intersection targets,and 340 signal pathways with hepatocirrhosis,mainly involving hepatitis C,JAK-STAT signal pathway and AGE-RAGE signal pathway.Targets,such as MAPK1,AKT1,TNF,JUN,IL6 and PTGS2,play important roles in the treatment.The findings suggested that the main active ingredients of Euphorbia fischeriana Steud.-Jujubae Fructus in treating hepatocirrhosis are quercetin,scopolamine,physcion,7-deoxyrangduin,17-Hydroxyjolkinolide A,etc.Molecular docking results showed that the main active components and core targets might have a good binding capacity.This study preliminarily explored the potential mechanism of Euphorbia fischeriana Steud.-Jujubae Fructus in treating hepatocirrhosis and provided a theoretical basis for the clinical application of Euphorbia fischeriana Steud.-Jujubae Fructus. 展开更多

[Objective] Taking silkworm (Bombyx mori) as the test material, the research aimed to study the toxicity effects of Euphorbiafischeriana Steud. against the insects in Lepidoptera. [ Methods ] Water extract was prepared with fresh perennial E. fischer/ana Steud. , which was applied in silkworm with different methods including daubing the extract on silkworm back, soaking silkworm in the extract and feeding silkworm with the mulberry leaves daubed by the extract. [ Re- suits] Those silkworms whose backs were daubed with the water extract had no obvious poisoning symptom. The silkworms soaked for 1 and 3 min could be survived for about 7 d; the silkworms soaked for 5 min could be survived for about 2 d; and the silkworms soaked for 15 rain could be survived for 10 h at most. Those silk- worms fed with mulberry leaves daubed by water extract completely died after 2 d. [ Conduslons ] The water extract of E. fischer/ana Steud. had significant contact toxicity and stomach poisoning against silkworm. 展开更多

It is very important to find out the reasons and the morphological changes of cattle abortion, death embryo and teratism in Sanjiang area, in order to determine the preventive measures, to improve animal quality, and to accelerate the animal industry. In the present studies, 25 cows and 25 local bos calves were investigated. The powder of Veratrum nigrum L. and Euphorbia fischeriana steud. was medicated to the animals during the 15 - 19th day of gestation. It was found that there were different poisoning reactions. When the poisoning was on the 15 - 16th day of gestation, the pregnant animals were easy to miscarriage. When the poisoning was on the 17 - 18th day of gestation, the embryos were easy to become teratism. The joint malformation bicephalus and rachischisis could take place for calves. If the poisoning was after 19th day of gestation , there were much more death embryos. The results of the studies showed that Veratrum and Euphorbia fischeriana steud. were the most poisonous plants to the animal industry of Sanjiang area. Some preventive measures were proposed. 展开更多

In order to determine genetic diversity of Oryza meyeriana (Zoll. et Mor. ex Steud. ) Baill., 12 enzyme systems encoded by 17 loci were electrophoretically analyzed in 164 individuals of seven populations from Simao Prefecture, Yunnan Province, China. In comparison with those seed plants with the same life history and breeding systems, as well as the other species in the genus Oryza, the species shows rather low levels of genetic diversity (A = 1.1, P = 8.0%, Ho = 0.004 and He = 0. 015) within populations and high genetic differentiation among populations. FST was up to 0. 649, suggesting that 64. 9% of total genetic variability exists among populations. Considering high genetic differentiation among populations from a limited geographic region, most of the populations of the species are worth being protected, and therefore, great natural protection regions should theoretically be established in which a great deal of populations should be involved for developing in situ conservation management. Meanwhile, some priory localities for in situ conservation of O. meyeriana in Yunnan Province, were proposed. 展开更多

Objective To identify the compounds withα-glucosidase inhibitory activity from Clerodendrum bungei Steud(Chou Mu Dan,臭牡丹)using HPLC-ESI-QTOF-MS/MS.Methods The ethanol extracts of Clerodendrum bungei Steud(Chou Mu Dan,臭牡丹)were partitioned with petroleum ether,ethyl acetate,n-butanol,and water.The assay forα-glucosidase inhibitory activity revealed strongα-glucosidase inhibitory activity in the ethyl acetate fraction,and the bioactive compounds present in this fraction were identified by the HPLCESI-QTOF-MS/MS method.Results A total of 29 compounds were determined,among the identified bioactive components;these included 12 phenylethanoid glycosides(compounds 5,6,17,20-22,24),7 flavonoids(compounds 10,19,23,25-28),5 phenolic acids(compounds 2-4,7,9),and 5 other compounds.Compounds 2-4,7,9-10,12-13,15,19,and 26,with a potentialα-glucosidase inhibitory activity,have been reported previously.Conclusions Our results show that the methodology used in this study is feasible,credible,and rapid in identifying known compounds and also for characterizing new natural glucosidase inhibitory candidates from Clerodendrum bungei Steud(Chou Mu Dan,臭牡丹). 展开更多
