摘　　要：Four new monoterpenoid indole alkaloids,alstrostines C-F together with thirteen known alkaloids were isolated from the leaves and twigs of Alstonia rostrata.All structures of new compounds were elucidated based on NMR,FTIR,UV,and MS spectroscopic data.Alstrostines C-E might originate from keto-enol tautomerism of preakummicine during biogenetic pathway of akummicine.
