Abstract
A new stilbene, gnetifolin M (1), was isolated from the lianas of Gnetum montanum, together with seven known compounds, resveratrol (2), gnetol (3), 4', 5,7-trihydroxy-3'-methoxyflavone, beta-sitosterol, daucosterol, ursolic acid, and tetracosanoic acid. The structure of 1 was determined to be 2-(5'-methoxy-3'-hydroxyphenyl)-4-hydroxybenzofuran on the basis of spectroscopic evidence.
