title: Galloylated catechins and stilbene diglucosides in Vitis vinifera cell suspension cultures.
abstract: Suspension cultures of Vitis vinifera were found to produce catechins and stilbenes. When cells were grown in a medium inducing polyphenol synthesis, (-)-epicatechin-3-O-gallate, dimeric procyanidin B-2 3'-O-gallate and two resveratrol diglucosides were isolated, together with a new natural compound that was identified as cis-resveratrol-3,4'-O-beta-diglucoside by spectroscopical methods.
