文摘A pregnane glycoside and a lignan glycoside were isolated from the aerial parts of Rubus amabilis. Their structures were elucidated as 3-O-beta-D-glucopyranosyl-3 beta.15 alpha-dihydroxypregn-5-en-20-one and (-)-secoisolariciresinol-O-alpha-L-rhamnopyranoside using spectroscopic and chemical methods.
