本文报告宣威乌头中存在四个类型的二萜生物碱:(1)阿替生型的denudatine,(2)维特钦型的songorine及songoramine,(3)牛扁碱型的virescenine及(4)乌头碱型的胺醇、单酯碱及双酯碱。这是迄今查到的国产乌头属植物中含二萜生物碱类型最多的一种植物。根据本文的化学工作及以前的工作,讨论了该种及其所属的保山乌头系分类问题,认为保山乌头可能是国产乌头组植物近代分化的中心之一。 This paper reports that there are four types of diterpene alkaloids in Xuanwei Aconitum: (1) the denudatine of the allisten type, (2) the sonorine and sonormine of the Vittic type, (3) the virecenine of the calichein type and (4) Aconitine-type amine alcohols, monoester bases, and diester bases. This is the type of plant containing the most diterpene alkaloids in the genus Aconitum that has been found so far. According to the chemical work and previous work of this paper, the classification of the Baoshan Aconitum system is discussed. It is believed that the Aconitum caryophyllus may be one of the centers of modern differentiation of domestic Aconitum.
