Oligostilbenes from the Roots of Vitis thunbergii

Abstract

Reinvestigating the constituents of the roots of Vitis thunbergii Sieb. & Zucc. led to the isolation of three new resveratrol derivatives, vitisinols E−G (1–3), together with 14 known compounds. The structures of compounds 1–3 were established by application of spectroscopic analyses (NMR, MS, UV, and IR).

Key words

Vitis thunbergii Sieb. & Zucc. - Vitaceae - vitisinols E−G - resveratrol derivative
