摘要: Chemical investigations of the whole plant ethanol extract of Rubus phoenicolasius led to the isolation and identification of a new pregnane glycoside, 3-O-beta-glucopyranosyl-3beta,15beta-dihydroxypregn-5-en-20-one (1), along with other nine known compounds (2-10). All the isolates were reported from this plant for the first time. The structure of compound 1 was determined by detailed analysis of its spectral data including ID and 2D NMR. In vitro anti-proliferative activities of compounds 1-3 on MCF-7 and NCI-H460 tumour cell lines were evaluated, and compound 1 was active against the two cell lines with IC_(50) values of 15.6 and 13.5 muM, respectively.
