摘要：
An inducible antifungal compound in grapevine leaves (Vitis vinifera L., cv Cabernet-Sauvignon) has been identified as trans-pterostilbene (3,5-dimethoxy-4′-hydroxy stilbene). It is only a minor component of the phytoalexin response of V. vinifera but its antifungal activity is relatively high by comparison with resveratrol and the viniferins, stress metabolites which have been identified previously in grapevine. Methods for the quantitative analysis of pterostilbene, resveratrol, ε- and α-viniferins by HPLC are described. © 1979.
