Studies on the chinese crude drug 'shoma.' VIII. Two new triterpenol bisdesmosides, 3-arabinosyl-24-O-acetylhydroshengmanol 15-glucoside and 3- xylosyl-24-O-acetylhydroshengmanol 15-glucoside, from Cimicifuga dahurica
Chemical and Pharmaceutical Bulletin 42(1) (1994) 48-51
 

Two new triterpenol glycosides were isolated from the rhizomes of Cimicifuga dahurica (Ranunculaceae) : 3-arabinosyl-24-O-acetylhydroshengmanol 15-glucoside (1), C_<43>H_<70>O_<16>, mp 222-223℃, [α]_D +21.0° and 3-xylosyl-24-O-acetylhydroshengmanol 15-glucoside (2), C_<43>H_<70>O_<16>, mp 208-210℃, [α]_D+9.5°. On acidic hydrolysis, 1 afforded cimigenol (3) as an aglycone, and glucose and arabinose as sugars. On enzymatic hydrolysis with molsin, 1 afforded 24-O-acetylhydroshengmanol 15-O-glucoside (4). On the basis of chemical and spectral data, the structure of 1 was proposed to be (23R, 24S)-24-acetoxy-3-O-α-L-arabinopyranosyloxy-16,23-epoxy-9,19-cyclolanostane-15α,16ξ,25-triol 15-O-β-D-glucopyranoside.The other glycoside (2) showed, in its ^<13>C-NMR spectrum, a pattern of chemical shifts very similar to that of 1. On acidic hydrolysis, 2 afforded cimigenol (3), xylose and glucose. On enzymatic hydrolysis with molsin, 2 afforded 4. From these results, the structure of 2 was proposed to be (23R, 24S)-24-acetoxy-3-O-β-D-xylo-pyranosyloxy-16,23-epoxy-9,19-cyclolanostane-15α,16ξ,25-triol 15-O-β-D-glucopyranoside.

New cycloartane glycosides from Cimicifuga dahurica
Planta Medica 65(8) (1999) 770-772
 

Two new cylcoartane glycosides along with a known compound, 12β-hydroxycimigenol 3-O-α-L-arabinopyranoside, were isolated from the rhizomes of Cimicifuga dahurica (Ranunculaceae). The structures of the new compounds were elucidated as cimigenol 3-O-α-L-arabinopyranoside and 25-O-acetylcimigenol 3-O-α-L-arabinopyranoside on the basis of chemical and spectral evidence.
