 One new Stemona alkaloid, dehydroisostemotinine (1) along with one known alkaloid isostemotinine (2), were isolated from the roots of Stemona tuberosa collected from Yunnan Province. The structure of the new alkaloid was established on the basis of one and twodimensional NMR spectra and other spectroscopic studies.

Key words: Stemona tuberosa, Stemona alkaloids, Dehydroisostemotinine
