Summary
1. Korsine and the new alkaloid korsinamine have been isolated from the epigeal part ofKorolkowia sewerzowii Rgl.
2. On the basis of the results of a study of the IR, NMR, and mass spectra of korsinamine and also of passage to the known alkaloid korsine, the structure of korsinamine has been established as 23β-O-acetylkorsine.
