Eight new glycosides were isolated from Cimicifuga simplex (Ranunculaceae), and their structures were determined to be 23-O-acetyl-7-8-didehydroshengmanol-3-O-alpha-L-arabinopyranosi de (1), 24-epi-24-O-acetyl-7,-8- didehydrohydroshengmanol-3-O-beta-D-galactopyranoside (2), 7,8-didehydrocimigenol-3-O-beta-D-galacytopyranoside (3), 24-epi-24-O-acetylhydroshengmanol-3-O-beta-D-galactopyranoside (4), cimigenol-3-O-beta-D-galactopyranoside (5), 25-O-methylcimigenol-3-O-beta-D-galactopyranoside (6), 25-O-acetylcimigenol-3-O-beta-D-galactopyranoside (7) and 25-O-acetylcimigenol-3-O-beta-D-glucopyranoside (8). Genuine aglycones were obtained by the hydrolysis of 1--7 with lactase F[Amano] and of 8 with cellulase T[amano]4. Acerinol was prepared from 7,8-didehydrocimigenol and showed antilipemic effects.
