title: Latifolosides K and L, two new triterpenoid saponins from the bark of Llex latifolia.
abstract: Two new triterpenoid saponins, latifoloside K (1), 3-O-beta-D-glucopyranosyl-(1-->3)-[alpha-L-rhamnopyranosyl-(1-->2)-]-alpha-L-arabinopyranosyl 3beta-hydroxy-urs-12,18-dien-28-oic acid 28-O-beta-D-glucopyranosyl ester and latifoloside L (2), 3-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->3)-[alpha-L-rhamnopyranosyl-(1-->2)-]-alpha-L-arabinopyranosyl 3beta,19alpha-dihydroxyursolic acid, were isolated from the bark of Ilex latifolia Thunb. Also isolated were two known compounds, ilekudinoside A (3) and kudinoside G (4). Structural assignments were established on the basis of spectroscopic data and chemical evidence.
