A new stilbene dimer from Vitis amurensis

Abstract

One new stilbene dimer named amurensin O (1), together with one known resveratrol trimer melapinol B (2), was isolated from Vitis amurensis, and their structures were identified on the basis of spectral analysis, especially 2D NMR spectral analysis.
