Four new steroidal saponins, polygonatosides A-D (1-4), were isolated from the rhizomes of Polygonatum zanlanscianense, together with six known spirostanols (5-10) and a known megastigmane glycoside (11). Their structures were elucidated on the basis of spectroscopic analysis and the results of acidic and enzymatic hydrolysis. The cytotoxic activities of 1-11 against HeLa cells are described.
从滇黄精的根茎中分离得到了4个新的甾体皂苷，即黄精苷A-D（1-4），同时还得到了6个已知的螺旋甾烷醇（5-10）和1个已知的巨大戟烷糖苷（11）。基于光谱分析以及酸水解和酶水解的结果阐明了它们的结构。描述了化合物1-11对人宫颈癌HeLa细胞的细胞毒活性。
