Abstract The genus Platycapnos differs from all other genera of the Fumariaceae in its alkaloid composition. The morphinandienone sinoacutine is the major alkaloid in the perennial P. saxicola while the annual species of the genus, P. spicata , P. tenuiloba subsp. tenuiloba and P. tenuiloba subsp. parallela contain high concentrations of aporphinoid alkaloids, mainly glaucine, nantenine and thalicthuberine
摘要 Platycapnos 属的生物碱成分与延胡索科的所有其他属不同。吗啡茚酮是多年生 P. saxicola 中的主要生物碱,而该属的一年生物种 P. spicata 、 P. tenuiloba subsp 是主要的生物碱。tenuiloba 和 P. tenuiloba subsp。parallela 含有高浓度的 aporphinoid 生物碱,主要是 glaucine、nantenine 和 thalicthuberine。

A new and direct synthesis of phenanthrenealkaloids using a low-valenttitaniumreagent is described which is compatible with ethoxycarbonyl as the N-protecting group.
