The structures of isolates were established based on spectroscopic analysis. The structures of vateriaphenols A and B were characterized as an octamer and a tetramer of resveratrol, respectively. The spectral properties of the highly condensed vateriaphenol A were also discussed. (C) 2003 Elsevier Science Ltd. All rights reserved. [References: 40] 收起
