TL;DR: The results indicate that the endophytic fungi of Chinese traditional medicinal plants are promising sources of novel bioactive compounds.
Abstract: One hundred and thirty endophytic fungi isolated from 12 Chinese traditional medicinal plants collected at Yuanmou county and Dawei Mountain, Yunnan province, southwest China, were tested for antitumour and antifungal activities by MTT assay on human gastric tumour cell line BGC-823 and the growth inhibition test against 7 phytopathogenic fungi. The results showed that fermentation broths from 9.2% of the isolates exhibited antitumour activity and 30% exhibited antifungal activity, moreover, some of them exhibited broad-spectrum antifungal activity. The active isolates were identified to 32 taxa. The results indicate that the endophytic fungi of Chinese traditional medicinal plants are promising sources of novel bioactive compounds.

TL;DR: The phytochemical present in the samples were juxtaposed with their ethnomedicinal significance, and from this, several suggestions were deduced on the secondary metabolites responsible for the pharmacological actions of the plants.
Abstract: This study involves the phytochemical screening and ethnomedicinal survey of twenty-three medicinal plants belonging to thirteen families commonly found in Nigeria. Semi-structured interviews and discussions with selected informants were adapted to collect ethnobotanical information on the plants. It was discovered that all of them possess alkaloids, tannins and saponin. Steroid is present in only twelve of the plant species, only five have phlobatannin; terpene is present in twenty of the plants, flavonoid is present in nineteen of the plants, while cardiac glycoside is present in sixteen of the species. Leea guineensis and Uvaria chamae were the only plants among the 23 plant samples that contain all the eight phytochemicals tested. The phytochemical present in the samples were juxtaposed with their ethnomedicinal significance, and from this, several suggestions were deduced on the secondary metabolites responsible for the pharmacological actions of the plants. Conclusively, it could be said that the ethnomedicinal significance of the selected plants for this study corresponds to the pharmacological actions of the secondary metabolites they contain.

TL;DR: The results support the view that herbs represent a rich source of anti‐lipase compounds, and found that several monomeric chemicals in these herbs exhibited good or moderate activity against PPL.
Abstract: activity. Results: Extracts from 2 herbs, Prunella vulgaris L. (Labiatae) and Rheum palmatum L. (Polygonaceae), at a concentration of 200 μg/mL, significantly inhibited PPL—by 74.7% and 53.8%, respectively. Quercetin exhibited better activity (27.4%) than all the other phytochemicals at a final concentration of 25 μg/mL in the assay system, followed by luteolin, with an activity of 17.3%. Conclusion: The results support the view that herbs represent a rich source of anti-lipase compounds. The screening of the methanolic extracts of 37 Chinese medicinal plants in vitro led to the identification of several extracts with potential activity against PPL, in particular, P. vulgaris and R. palmatum. We also found that several monomeric chemicals in these herbs exhibited good or moderate activity against PPL. To the best of our knowledge, these traditional Chinese herbal medicines or phytochemicals have not been previously screened for their lipase inhibitory activity.

TL;DR: This is the first ethno botanical study in which statistical calculations about plants are done by ICF method and indicated that dermatological infections/diseases and gastro-intestinal disorders had highest use reports and 7 species of plants has the highest fidelity level of 100%.
