罗布麻科植物罗布麻属植物的树皮和树皮中含有14种吲哚类生物碱和3种三萜类化合物。其中6个菌株,喜树碱(2)、9-甲氧基喜树碱(3)、冠花碱(1)、冠周菌素(25)、Heyneatine(18)和10-甲氧基腺苷-N-氧化物(4)具有细胞毒活性。其中3个吲哚生物碱18、4和10-羟基冠醚(8)是iboga系列中的新成员,它们的结构通过光谱解析和化学关联确定。
The wood and stem bark of E. heyneana (Apocynaceae) yielded 14 indole alkaloids and 3 triterpenoids. Six of these isolates, camptothecin (2), 9-methoxycamptothecin (3), coronaridine (1), pericalline (25), heyneatine (18) and 10-methoxyeglandine-N-oxide (4) displayed cytotoxic activity. Three of the indole alkaloids 18, 4 and 10-hydroxycoronaridine (8) are new members in the iboga series and their structures were determined by a combination of spectral interpretation and chemical correlation.
