title: Mono- and diglycosides of (E)-6,9-dihydroxymegastigma-4,7-dien-3-one in Vitis vinifera wine.
abstract: Two beta-D-glucopyranosides and two 6-O-beta-D-apiofuranosyl-beta-D-glucopyranosides of (E)-6,9-dihydroxymegastigma-4,7-dien-3-one were isolated from Vitis vinifera cv. Gewürztraminer wine and their structures were established by NMR spectroscopy.
