Leeaoside, a new megastigmane diglycoside from the leaves of Leea thorelii Gagnep

摘要

A new megastigmane diglycoside, leeaoside, was isolated along with four known compounds; benzyl O-a-L-rhamnopyranosyl-(l -> 6)-beta-D-glucopyranoside, qu-ercetin 3-O-a-L-rhamnopyranoside, myricetin 3-O-a-L-rham-nopyranoside and citroside A from the leaves of Leea thorelii. The structure determinations were based on physical data and spectroscopic evidence.
