为了研究藏药臭蚤草的活性成分,从其总碱中分离并通过核磁共振和质谱等方法鉴定了8个生物碱,包括6个二萜类生物碱13-O-acetylhetisine(1)、2-acetyl-13-dehydro-11-epihetisine(2)、2-acetyl-13-dehydro-11-hetisine(3)、hetisinone(4)、尼奥林(5)和foresticine(6),以及异喹啉(7)和dianthrmide(8)。所有化合物均首次从该植物中分离得到。
Six diterpenoid alkaloids 13-O-acetylhetisine(1),2-acetyl-13-dehydro-11-epihetisine(2),2-acetyl-13-dehydro-11-hetisine(3),hetisinone(4),neoline(5),and foresticine(6),together with isoquinoline(7) and dianthrmide(8),were isolated from the Tibetan folk drug Aconitum naviculare.Their structures were elucidated based on 1H and 13C NMR and MS.This is the first report of the presence of compounds 1-8 in this plant.
