| Abstract: | 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. |
