[Abstract]
Object To study the chemical constituents of alkaloids of A msonia sinensis Tsiang extracted with methanol. Methods Compounds were separated by exchange resin, macroporous resin and silica gel co-lumn chromatography. Their structures were elucidated by spectroscopic analysis. Results Three compounds were isolated from total alkaloids of A. sinensis extracted with methanol. T hey were identified as: rhazidigenine (Ⅰ), amsonic acid (Ⅱ), trans-sinapic acid methylester (Ⅲ). Conclusion Compound Ⅱ is a new one,and compound Ⅰ and Ⅲ are obtained from this plant for the first time.
