Studies on the Constituents of Cimicifuga Species. XXVII. Malonyl Cyclolanostanol Glycosides from the Underground Parts of Cimicifuga simplex WORMSK.

抄録

Five malonyl cyclolanostanol glycosides, 23-O-acetyl-7, 8-didehydroshengmanol 3-O-(2'-O-malonyl)-β-D-xylopyranoside, 23-O-acetylshengmanol 3-O-(2'-O-malonyl)-β-D-xylopyranoside, 2'-O-malonylcimicifugoside, 24-epi-24-O-acetyl-7, 8-didehydrohydroshengmanol 3-O-(2'-O-malonyl)-β-D-xylopyranoside, and 2'-O-malonylcimiaceroside B, were isolated from the underground parts of Cimicifuga simplex WORMSK. (Ranunculaceae), together with two related cyclolanostanol glycosides, 23-O-acetyl-7, 8-didehydroshengmanol 3-O-β-D-xylopyranoside, 24-O-acetyl-25-O-methyl-7, 8-didehydrohydroshengmanol 3-O-β-D-xylopyranoside. Their structures were elucidated on the basis of spectral and chemical evidence.
