Diterpenoid alkaloids from the roots of Aconitum brachypodum Diels. And their chemotaxonomic significance

Publication date: August 2019Source: Biochemical Systematics and Ecology, Volume 85Author(s): Liguo Yang, Yingjie Zhang, Shuangxi Mei, Zhaoyun ZhuAbstractFrom the roots of Aconitum brachypodum Diels., twelve diterpenoid alkaloids, such as bullatine H (1), 16, 17-dihydroxylepenine (2), N-ethyl-1α-hydroxydictizine (3), bullatine A (4), lepenine (5), 12-epi-napelline (6), songoramine (7), aconine (8), N-deethyldeoxyaconitine (9), aconitine (10), N-deethyl-3-acetylaconitine (11) and N-deethylaconitine (12) were isolated and identified. Structure elucidation of these compounds was performed on the basis of NMR spectroscopic data. Compounds 2, 3, 6, 7, 9 and 12 were obtained from this species for the first time. Chemotaxonomic significance of these compounds is described herein.
