摘　　要：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-dihydroisositsirikine （Ⅲ）, 19-s-voacangarine （Ⅳ）, 1 l＇-methoxyl-19s- heyneanine （Ⅴ）, conodurine （Ⅵ）. The structural elucidation of the alkaloids was based on spectral means.Six indole alkaloids were isolated from the stems of Ervatamia yunnanensis.
