Abstract:
Abstract Four stilbenoids isolated from the stems of Vitis wilsonae Veith. were determined as gnetin A, (+)εvineferin, ampelopsin E and vitisin A. The structure of vitisin A was identified on the basis of spectroscopic evidence, especially by 2D NMR methods, such as HHCOSY, CHCOSY, COLOC and NOESY spectra. All the oligostilbenes were isolated from this plant for the first time.
