[Study on the chemical constituents of Uvaria microcarpa].
OBJECTIVE
To study the chemical constituents of Uvaria microcarpa.


METHODS
The constituents were repeatedly separated and purified with silica gel column and Sephadex LH-20 column, and identified by physico-chemical properties and spectral methods.


RESULTS
Nine compounds were separated and identified as beta-sitosterol palmitate (I), euphorginol (II), beta-sitosterol (III), benzoic acid(IV), stigmasterol-3-O-beta-D-glucopyranoside (V), taraxerol (VI), emodin (VII), aristololactam A II (VI), beta-daucosterol (IX) .


CONCLUSIONS
Compounds I, II, V, V are isolated from this plant for the first time.
