title: Stemoninine-type alkaloids from the roots of Stemona sessilifolia.
abstract: Two new stemoninine-type alkaloids, stemoninine A (1) and B (2), along with two known Stemona alkaloids, bisdehydrostemoninine (3) and bisdehydrostemoninine A (4), were isolated from the roots of Stemona sessilifolia, and their structures and relative configurations were determined on the basis of spectrometric data analysis.
