Six indole alkaloids were isolated from the stems of Ervatamia yunnanensis. Among them, 10-hydroxy-19, 20-dihydroisositsirikine (Ⅰ) is new. The other five are known alkaloids, namely: matrine (Ⅱ), 19, 20-dihydroisositsuikine (Ⅲ), 19-s-voacangarine (Ⅳ), 11'-methoxyl-19s-heyneanine (Ⅴ), conodurine (Ⅵ). The structural elucidation of the alkaloids was based on spectral means.
