Shegansu C, a Novel Phenylpropanoid Ester of Sucrose from Belamcanda chinensis

Abstract A novel phenylpropanoid ester of sucrose, shegansu C (1), was isolated from the rhizome of Belamcanda chinensis (L.) DC. (Iridaceae) along with 18 known compounds. The structure of 1 was characterized as β-D-[3-O-(4-O-(3,4-,dimethoxycinnamoyl)-5-O-feruloyl)-caffeoyl]-fructofuranosyl(2-1′)-α-D-(3′-O-acetyl)-glucopyranoside on the basis of chemical and spectral evidence including 2DNMR studies.
