  Spirostanol and Furostanol Glycosides from the Fresh Tubers of Polianthes tuberosa

  摘要：

  Six new steroid glycosides-two spirostanols, polianthosides B and C (1, 2), and four furostanols, polianthosides D-G (3-6)-were isolated from the fresh tubers of Polianthes tuberosa, together with seven known spirostanols (7-13) and a known furostanol (14) saponins. Their structures were elucidated on the basis of spectroscopic analysis and the results of acidic and enzymatic hydrolysis. The cytotoxic activities of 1-14 against HeLa cells are reported.

  A chemical investigation of the aerial parts of Polianthes tuberosa resulted in the isolation of a new bisdesmosidic cholestane glycoside (1) and three new spirostanol saponins (2-4), along with a known cholestane glycoside. The structures of new glycosides were determined by spectroscopic analysis, including 2D NMR spectroscopic data, and the results of hydrolytic cleavage. The isolated compounds
