AIM： To study the chemical constituents of Ervatamia hainanensis. METHODS： Chemical constituents were isolated by various column chromatographic techniques and their structures were elucidated by spectroscopic methods. RESULTS： Ten compounds were obtained from Ervatamia hainanensis and identified as 8-hydroxy-6-methoxy-3- n-pentylisocoumarin （1）, cycloartenol, （2） cycloart-23-ene-3β, 25-diol （3）, obtusifoliol （4）, α-amyrin （5）, α-amyrin acetate （6）, 11-oxo-cz-amyrin acetate （7）, β-amyrin acetate （8）, stigmasterol （9）, stigmasta-4-en-3-one （10）, respectively. CONCLUSION： Compounds 1, 4, 9 and 10 have been isolated from this plant for the first time, and compounds 1 and 4 have been first obtained from Ervatamia genus.
