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,分别命名为紫草乌碱丙(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~(13)C NMR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。
From the Aconitum delavayi Franch, four alkaloids were also obtained, three of which were new diterpenoid alkaloids. They were named as delavaconitine C (3) and phytosanitrine. Determination of delavaconitine D (5) and delavaconitime E (6) by acetylation, hydrolysis, and UV, IR, MS, ~1H, and ~(13)C NMR measurements to determine their chemical structures. . Another identified delavaconine (2) was isolated from the plant for the first time.
