| Abstract: | From the roots of Aconitum nagarum var. lasiandrum W. T. Wang, seven diterpe- noid alkaloids were isolated and determined as follows: denudatine of atisine-type (7), songorine and songoramine of veatchine-type (1 and 12), virescenine of lycoctonine-type (13), neoline, 14-acetylneoline and fiavaconitine of aconitine-type (2, 3 and 8). A. nagarum var. lasiandrum W. T. Wang is a typical species of Ser. Bullatifolia which contained four types diterpenoid alkaloids. On the basis of distribution of diterpenoid alkaloids, phytogenesis add morphological evolution of Chinese species of genus Aconitum, probably Chinese species of genus Aconitum modernly advanced and divided from this serics. |
