Three new terpenoids compounds (1–3) were obtained from ethyl acetate fraction, which was yielded from Eupatorium chinense’s ethanol extract. Their structures were determined on the basis of 1D and 2D NMR spectroscopy, including 1H-1H COSY, HMBC, HSQC and NOESY experiments. All of the isolated compounds were tested in vitro for their cytotoxic activities against the HepG2, HGC-27 and MDA-MB-231 cancer...
Two new steroidal glycosides (1–2) were isolated from the roots of Reineckia carnea, together with three known compounds (3–5). Their structures were determined on the basis of chemical methods and spectral data. Compounds 1–2 were the unique steroidal glycosides possessing structural feature of 14α-hydroxy-5β-steroids, and compounds 4–5 were isolated from R. carnea for the first time. The isolated...
