| Abstract: | A new megastigmane diglycoside, leeaoside, was isolated along with four known compounds; benzyl O-α-l-rhamnopyranosyl-(1 → 6)-β-d-glucopyranoside, quercetin 3-O-α-l-rhamnopyranoside, myricetin 3-O-α-l-rhamnopyranoside and citroside A from the leaves of Leea thorelli. The structure determinations were based on physical data and spectroscopic evidence. |
