STUDIES ON THE TRITERPENOID CONSTITUENTS FROM THE AERIAL PART OF CIMICIFUGA FOETIDA L.

AIMTo look for new active constituents from the aerial part of Cimicifuga foetida L. METHODS Various column chromatographic techniques were used for the isolation and purification of the ingredients. The structure were elucidated on the basis of spectral evidences and chemical reaction. RESULTSFive compounds were obtained and identified as 23-O-acetylshengmanol-3-O-α-L-arabinopyranoside (1), 23-O-acetylshengmanol-3-O-β-D-xylopyranoside (2), 25-anhydrocimigenol-3-O-β-D-xylopyranoside (3), cimigenol-3-O-α-L-arabinopyranoside (4), cimigenol-3-O-β-D-xylopyranoside (5). CONCLUSIONCompound 1 is a new compound, and compounds 2 and 4 were isolated from this plant for the first time.
