摘要
二新奇 steroidal saponins (timosaponin 双性人 -- 一， timosaponin BIII-b ) 和已知的 steroidal， saponin (timosaponin BII-b ) 被 timosaponin 的 dilute 酸水解作用准备双性人。他们的结构借助于 1D， 2D NMR 和 TOFMS 被阐明光谱分析。
Two novel steroidal saponins（timosaponin BⅢ-a,timosaponin BⅢ-b） together with a known steroidal saponin（timosaponin BⅡ-b） were prepared by the dilute acid hydrolysis of timosaponin BⅢ.Their structures were elucidated by means of 1D,2D NMR and TOF-MS spectral analysis.
