摘要：
Two new triterpenoid saponins, latifoloside I (1), 3-O-alpha -L-rhamnopyranosyl-(1-->2)-beta -D-glucopyranosyl 3 beta ,21 alpha ,28-trihydrosy-urs-12-ene 21-O-beta -D-glucopyranoside; latifoloside J (2), 3-O-alpha -L-rhamnopyranosyl-(1-->2)-beta -D-glucopyranosyl-3 beta ,21 alpha -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.
