Pw. Teguo et al., THE ACCUMULATION OF STILBENE GLYCOSIDES IN VITIS-VINIFERA CELL-SUSPENSION CULTURES, Journal of natural products, 59(12), 1996, pp. 1189-1191
Suspension cultures of Vitis vinifera grown in an inducive polyphenol
synthesis medium accumulated stilbene glycosides. (E)-piceatannol (3,5
,3',4'-tetrahydroxystilbene) 3-O-beta-glucoside (2) and (Z)-resveratro
l (3,5,4'-trihydroxystilbene) 3-O-beta-glucoside (3) were isolated fro
m these cells. Their complete structures were determined by 1D and 2D
NMR techniques.
