Three New Stilbene Trimers from the Lianas of Gnetum hainanense

Abstract

Three new stilbene trimers, gnetuhainins M-O (1 - 3), were isolated from the lianas of Gnetum hainanense. Their structures and relative configurations were determined by spectroscopic evidence, especially on 2D NMR analysis. The anti-inflammatory activity has been tested for the isolated compounds.

Key words

Gnetum hainanense - Gnetaceae - oligostilbenes - resveratrol - oxyresveratrol - isorhapontigenin - gnetuhainins M-O
