Popis:	One new stenine-type alkaloid, tuberostemonine D ( 1 ), together with five known stenine-type alkaloids ( 2 – 6 ) and two known stemoninine-type alkaloids ( 7 and 8 ), were isolated from the roots of Stemona tuberosa . Their structures were elucidated by extensive spectroscopic methods (IR, UV, MS, 1D and 2D NMR), and the structure of 1 was further confirmed by X-ray diffraction analysis. First simultaneous isolation of stenine- and stemoninine-type alkaloids not only added a new chemical type and increased the chemical diversity of Stemona tuberosa , but also provided chemotaxonomic clues for the close relationship between genera Stemona and Stichoneuron , and favored retaining them in the same family.
