从云南紫草乌(Aconitum delavayi Franch)中又分得四个生物碱, 其中三个为新的二萜类生物碱, 分别命为紫草乌碱丙(delavaconitine C,3),紫草乌碱丁(delavaconitine D,5)和紫草乌碱戊(delavaconitime E,6),经乙酰 化、水解及UV、IR、MS、^1H和^1^3CNMR 的测定, 确定了它们的化学结构。另一个经鉴定为紫草乌碱甲胺醇(delavaconine, 2), 首次从植物中分离得到。

Three new alkaloids, delavaconitine C I (R1 = R3 = H; R2 = Bz), delavaconitine D I (R1 = Ac; R2 = Bz; R3 = H), and delavaconitine E I (R1 = H; R2 = Bz; R3 = OAc) and a known alkaloid, delavaconine, were isolated from the roots of A. delavayi. The chem. structures of I were established by UV, IR, MS, 1H and 13C NMR spectral data and chem. evidence. Delavaconine was isolated from the plant for the first time.
