Two new alkaloids, sessilifolines A ( 1 ) and B ( 2a ), were isolated from the stems of Stemona sessilifolia , together with three known alkaloids, tuberstemonine ( 3 ), sessilifoliamide A ( 4 ), and stemoninoamide ( 5 ). Their structures were established by mass‐spectrometric and spectroscopic methods, especially 2D‐NMR techniques.
