Diterpene Alkaloids of Aconitum kirinense Nakai I.Lepe-nine and Kirinine A

wo diterpene alkaloids, lepenine and kirinine A were isolated for the first time from the roots of Aconitum kirinense Nakai. Their structures have been established by IR, HRMS, NMR analysis and chemical reactions, and kininine A was found to be a new C 20 diterpene alkaloid.

高乌头中1个新的二萜类生物碱成分

目的研究高乌头Aconitum sinomontanum根的化学成分。方法采用硅胶、葡聚糖凝胶Sephadex LH-20、半制备高效液相等色谱技术进行分离纯化,根据理化性质和波谱方法进行结构鉴定。结果从高乌头根80%乙醇提取物中分离得到5个化合物,分别鉴定为6β,7β,8β,15α-tetrahydroxy-1α,14α,16β,18β-tetramethoxy-aconitan-19-en(1)、飞燕草碱(2)、lepenine(3)、napelline(4)、kirinine B(5)。结论化合物1为新化合物,命名为冉乌宁J,化合物2~5为首次从高乌头中分离得到。
