摘　　要：进行了白首乌中C2 1甾甙元的分离和结构鉴定 .首先从白首乌中提取了C2 1甾甙元 ,通过酸解和进一步提取得到C2 1总甙元 .总甙元再经色谱分离和制备 ,得两种甾甙元 ,通过红外、质谱、核磁图谱分析 。The C 21 steroidal aglycones in Baishouwu were isolated and characterized. The C 21 steroidal glycosides extracted in advance from Baishouwu were acidolyzed and the general aglycones were extracted. Two kinds of aglycones were obtained after chromatography analysis and preparation. The two kinds of aglycones were determined as caudatin and kidjolanin by infrared spectroscopy, mass spectroscopy, and nuclear magnetic resonance spectroscopy.
