Constituents of Chinese Crude Drug “Wujiapi” . IV. On the Structure of a New Acetylbiose from Steroidal Glycosides of Bei-Wujiapi

抄録

The chemical structures of two hydrolysis products of the crude glycoside fractiion of Chinese crude drug “Bei-Wujiapi (cortex of Periploca sepium BGE.)” were studied. The one product is 4-O-(2-O-acetyl-β-D-digitalopyranosyl)-D-cymaropyranose and the other is methyl 4-O-(2-O-acetyl-β-D-digitalopyranosyl)-β-D-cymaropyranoside.
