From A. australe the following alkaloids were isolated: from the aereal bark olivacine and (±) guatambine; from the heartwood, olivacine and a base m.p. 186–188° present in very small amounts; from root bark, olivacine, (+) guatambuine (u-alkaloid C), (-) guatambuine and uleine; from root heartwood, olivacine. (±) Guatambuine is N-methyl-tetrahydro-olivacine. The products of the Hofmann degradation
从A. atratrale中分离出以下生物碱:从大叶树皮中的寡糖和(±)瓜丹滨;来自心材,橄榄石和mp 186–188°的基本成分,数量很少;来自根皮,寡糖,(+)guatambuine(u-生物碱C),(-)guatambuine和uleine; 从根心材中提取出来。(±)Guatambuine是N-甲基-四氢-olivacine。最后一个碱基的霍夫曼降解产物与从uleine中获得的产物相同,该结果将两个碱基关联起来,并确定地建立了(±)guatambuine(III)和olivacine(I)的结构。
