Studies on the Constituents of Cimicifuga Species. XVIII. Four New Xylosides from the Aerial Parts of Cimicifuga simplex WORMSK.

Abstract

Four new xylosides (1-4) were isolated from the aerial parts of Cimicifuga simplex (Ranunculaceae), and their structures were determined to be 24-epi-7β-hydroxy-24-O-acetylhydroshengmanol-3-O-β-D-xylopyranoside (1), 25-O-methyl-24-O-acetylhydroshengmanol-3-O-β-D-xylopyranoside (2), 25-O-methyl-7β-hydroxy-24-O-acetylhydroshengmanol-3-O-β-D-xylopyranoside (3) and 25-O-methyl-1α-hydroxy-24-O-acetylhydroshengmanol-3-O-β-D-xylopyranoside (4).
