Two new diglycosides (I, II) were isolated from the aerial parts of Cimicifuga simplex (Ranunculaceae), and their structures were determined to be 25-O-acetylcimigenol 3-O-β-D-glucopyranosyl-(1 → 3)-β-D-xylopyranoside (I) and 23-O-acetylshengmanol 3-O-β-D-glucopyranosyl-(1 → 3)-β-D-xylopyranoside(II). Two known xylosides (Ia, IIa) were also isolated and identified as 25-O-acetylcimigenol 3-O-β-D-xylopyranoside (Ia) and 23-O-acetylshengmanol 3-O-β-D-xylopyranoside (IIa). Cellulase A [Amano] 3 hydrolyzed I and II to afford Ia and IIa respectively, while Cellulase T [Amano] 4 hydrolyzed I and II to afford 25-O-acetylcimigenol (Ib) and 23-O-acetylshengmanol (IIb) as the aglycones, respectively.
