title: Triterpenoid glycosides from Ilex kudincha.
abstract: Three new saponins, named kudinosides A, B and C, were isolated from the leaves of Ilex kudincha. On the basis of spectroscopic analysis and chemical transformation their structures were elucidated as 3-O-beta-D-glucopyranosyl-(1-->3)-[alpha-L-rhamnopyranosyl- (1-->2)]-alpha-L-arabinopyranosyl-beta-kudinlactone, 3-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->3)-alpha-L- arabinopyranosyl-beta-kudinlactone and 3-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->3)-[alpha-L -rhamnopyranosyl-(1-->2)]-alpha-L-arabinopyranosyl-beta-kudinla c tone.
