Abstract

Phytochemical constituents of Vitis wenchowensis were investigated for the first time. A new resveratrol trimer, wenchowenol (1), was isolated from the roots and stems of Vitis wenchowensis along with four known stilbenoids 2-5. The structure and relative configuration of 1 were established on the basis of spectral evidence, especially HMBC and NOESY experiments. It showed potent antioxidant activity against DPPH (1,1-diphenyl-2-picrylhydrazyl) radical.

摘要

首次对山葡萄根和茎的化学成分进行了研究。从山葡萄根和茎中分离得到一个新的白藜芦醇三聚体 wenchowenol（1），并与四个已知的二苯乙烯类化合物 2-5 一起分离得到。根据光谱证据，特别是 HMBC 和 NOESY 实验，确定了 1 的结构和相对构型。它对 1,1-二苯基-2-苦基肼（DPPH）自由基表现出很强的抗氧化活性。
