Three new selaginellin derivatives, selaginpulvilins V‐X (1–3), together with seven known analogs (4–10) were isolated from whole plants of Selaginella pulvinata. Their structures were determined by extensive spectroscopic methods including 1D and 2D NMR, HR‐ESI‐MS and chemical derivatization method. Compound 1 represents a rare example of naturally occurring selaginellin with an alkynylphenol‐trimmed...
Sex‐related differences on phenolic profiles, chemical composition of essential oils, anatomy, histochemistry and biological activities (antioxidant and antibacterial activities) of Juniperus rigida needles collected from Yijun and Fugu region were first studied. In two regions, female and male had similar contents of total phenolic and total flavonoid. 10 phenolic compounds were analyzed by RP‐HPLC,...
