【摘要】 从喜树(Camptetheca acuminata Decne)果中分到五个微量吲哚类生物碱,其中两个为新生物碱,分别为 camptacnmotine(1)和 camptacumanine(2),另外三个为已知生物碱 naucleficine(3),angustoline(4)和新天然产物二氢异喹胺(dihydroisoquinamine,5).更多还原

【Abstract】 Five minor alkaloids were isolated from the seeds of Camptotheca acuminata Decne.Two of them are new indole alkaloids named camptacumotine(1)and camptacumanine(2)respectively,and the others are known indole alkaloids naucleficine(3),angusto-line(4)and dihydroisoquinamine(5),the latter is isolated for the first time from theplant.The structure of 1 and 2 were elucidated through spectral studies.更多还原
