  Cycloartane-type sapogenins and their glycosides from Curculigo orchioides

  摘要：

  Several new cycloartane glycosides were isolated from rhizomes of Curculigo orchioides. Among them, two new triterpenoidal sapogenins named curculigenin B and C, which are common to three saponins, were formulated as (24S)-3-beta,11-alpha,16-beta,24-tetrahydroxycycloartane and 3-beta,11-alpha,16-beta-trihydroxycycloartane-24(25)-en, respectively, by H-1, C-13 NMR, 2D NMR analysis and chemical evidence. The structures of curculigosaponin K, L and M were elucidated on the basis of chemical methods and spectral data.
