title: Latifolosides I and J, two new triterpenoid saponins from the bark of Ilex latifolia.
abstract: Two new triterpenoid saponins, latifoloside I (1), 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranosyl 3beta,21alpha,28-trihydroxy-urs-12-ene 21-O-beta-D-glucopyranoside; latifoloside J (2), 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranosyl-3beta,21alpha-dihydroxy-ursolic acid 21-O-beta-D-glucopyranoside, along with two known compounds, latifoloside C (3) and latifoloside E (4), were isolated from the bark of Ilex latifolia THUNB. Structure assignments were established on the basis of spectroscopic data and chemical evidence.
