摘要:
Two novel ester alkaloids, incarvines B and C, were isolated from the aerial parts of Incarvillea sinensis. On the basis of chemical and spectroscopic evidence, incarvine B was characterized as the ester of the monoterpene alkaloid, incarvilline, and the monoterpene acid, Hildebrandt's acid, whilst the structure of incarvine C was established as incarvilline 7-O-ferulate.
