Aim: To seek for new bioactive constituents from the aerial parts of Cimicifuga dahurica.
Methods: Various column chromatographic techniques were employed for the isolation and purification of the ingredients. The structures were elucidated on the basis of 1H, 13CNMR, 1H-1H COSY, HMQC, NOESY and HMBC spectra and chemical reactions.
Results: Two cyclolanostanol xylosides, cimidahuside C and D were isolated from the EtOAc section of EtOH extracts.
Conclusion: Cimidahuside C(1) and D(2) are new triterpenoid xylosides.
