title: Pregnane glycoside, lignan glycosides, triterpene glycosyl ester and flavonoid glycosides from Rubus amabilis.
abstract: Two new compounds, 3-O-beta-D-glucopyranosyl-3 beta, 15 alpha-dihydroxypregn-5-en-20-one (1) and (-)-secoisolariciresinol-O-alpha-L-rhamnopyranoside (2), along with six known compounds (3-8), have been isolated from the aerial parts of Rubus amabilis Focke. The structures of the new compounds were elucidated mainly by spectroscopic methods and some chemical transformations.
