Studies on the Constituents of Cimicifuga spp. XIII. Structure of Cimicifugoside

抄録

Cimicifugoside (I), mp 237-238°, C₃₇H₅₄O<<11> was isolated along with friedelin, β-sitosterol, β-sitosteryl glucoside, 25-O-methylcimigenol, cimigenol and cimigenyl xyloside from the roots of Cimicifuga simplex. The structure (I) was proposed for cimicifugoside on the basis of chemical and physicochemical data. The major topic is chemistry of a hydrolysis product, cimicifugenin A (IV) and its derivatives.
