[Study on the chemical constituets in ethyl acetante extraction from semen litchi].
OBJECTIVE
To study the chemical constituents in ethyl acetate extraction of Semen Litchi.


METHODS
The compounds were isolated and purified by column chromatography on silica gel and Sephadex LH-20 coupled with preparative silica gel TLC, their structures were identified by physicochemical properties and spectrum analysis.


RESULTS
Five compounds were isolated and identified as stigmasterol (1), P-hydroxy-benzaldehyde (2), protocatechuic acid (3), daucosterol (4) and kaempferol-3-O-beta-D-glucopyranoside (5).


CONCLUSIONS
Compounds 2 and 5 are obtained from this plant for the first time.
