Abstract :
Three new alkaloids, stemona-amines C–E, were isolated from the roots of Stemona tuberosa Lour. (Stemonaceae). The structures of stemona-amines C and D were determined by X-ray crystallography and that of stemona-amine E was determined by interpretation of spectroscopic data. The absolute structures of stemona-amines C and D were established by VCD spectroscopy.
