Abstract
A new dimeric stilbene, named shegansu B (1) was isolated from the ethanolic extract of the roots of Belamcanda chinensis (L.) DC., along with the known compounds isorhapontigenin, resveratol, p-hydroxybenzoic acid, iridin, tectoridin, tectorigenin and daucosterol. The structures were elucidated by means of spectroscopic evidence including 2D-NMR studies.
