Sessilifoliamine A and sessilifoliamide J: new alkaloids from Stemona sessilifolia

Two new alkaloids, sessilifoliamine A and sessilifoliamide J, having novel alkaloid skeletons were isolated from the roots of Stemona sessilifolia (Miq.) Miq. (Stemonaceae). The structure of sessilifoliamine A was determined by interpretation of its spectroscopic data and that of sessilifoliamide J by X-ray crystallography.
