title: A new resveratrol trimer derivative from Gnetum brunonianum.
abstract: A new resveratrol trimer derivative, named as gnetubrunol A (1), together with five known stilbene derivatives, shegansu B (2), resveratrol (3), isorhapontigenin (4), gnetifolin E (5), and isorhapontigenin-11-O-β-d-glucopyranoside (6) were isolated from the lianas of Gnetum brunonianum Griff. Their structures were elucidated on the basis of spectral analysis (UV, IR, MS, (1)H NMR, (13)C NMR, and 2D NMR). The anti-inflammatory activities of 1, 5, and 6 have also been assayed.
