Three quaternary alkaloids have been isolated from root barks of STRYCHNOS USAMBARENSIS Gilg from Rwanda: malindine, isomalindine and Nb-methyl-antirhine. The structure elucidation and the stereochemistry of the new isomalindine has been proposed based on its spectral data and their comparison with those of malindine, its isomer.
从卢旺达产马钱科密花马钱 Strychnos usambarensis Gilg 的根皮中分离得到了 3 种季铵型生物碱:马钱宁、异马钱宁和 Nb-甲基-阿枯米定。根据其波谱数据及其与异构体马钱宁的比较,提出了新的异马钱宁的结构阐明和立体化学。
