A new monoterpenoid indole alkaloid, 15,20-dehydro-3α-(2-oxopropyl) coronaridine (1), along with sixteen analogues (2-17) were isolated from the leaves of Catharanthus roseus cultivated in Yunnan. The new alkaloid was elucidated on the basis of extensive spectroscopic analysis, and the known alkaloids were identified by comparison with the reported spectroscopic data. Among them, alkaloid 16 was isolated from Catharanthus for the first time.
