Two Novel Actinidine-Type Monoterpene Alkaloids from Incarvillea delavayi

摘要

Two new actinidine-type monoterpene alkaloids, delavayines B(1) and C(2), were isolated from the MeOH extract of the aerial parts of Incarvillea delavayi, a close species of which, I. sinensis, is used as an analgesic for rheumatic pain in China, and the structures have been elucidated on the basis of spectroscopic evidence.
