title: Saniculoside R-1: a new triterpenoid saponin from Sanicula europaea.
abstract: A new acylated triterpenoid saponin was obtained from the leaves of Sanicula europaea. The structure has been elucidated from NMR and MS data, and by chemical derivatisation as 21-O-[2-methylbutanoyl]-3 beta, 15 alpha, 16 alpha, 21 beta, 22 alpha, 28-hexahydroxyolean-12-ene 3-O-[alpha-L-arabinopyranosyl (1-->3)] beta-D-glucopyranosyl(1-->2)-beta-D-glucuronopyranoside.
