Abstract��
OBJECTIVE:To investigate the alkaloids of Ozhangye Fuzi��one of the three cultispecies of Aconitum carmichaeli, from Zhongba �� Sichuan. METHODS �� To isolate the alkaloids �� the solvent-extraction together with the column �� chromatography and thin-layer chromatography methods were used. Several spectral methods such as IR��1HNMR.13C-NMR and MS were used to determine the structure of the isolated alkaloids.RESULTS and CONCLUSION: In ten alkaloids obtained,five were two C20-diterpenoid alkaloids,songoramine(4) and songorine(5) a-long wiyh three C19-diterpenoid alkaloids,aconitine(1),neoline(3),and fuziline(2) were determined and confirmed. Songoramine has not been reported previously in this plant.
