Arch Pharm Res. 2000 Apr;23(2):159-62. doi: 10.1007/BF02975506.

Abstract

A new stilbene diglycoside, piceatannol-3, 4'-O-beta-D-diglucopyranoside (I), together with desoxyrhaponticin (II), emodin-1-O-beta-D-glucopyranoside (III), and physcion-8-O-b-D-glucopyranoside (IV), were isolated from the rhizomes of cultivated Korean rhubarb rhizomes (Rheum undulatum), Jong DaeWhang, and the structures of I-IV were identified on the basis of chemical and spectral evidences.
