[Chemical constituents of mangrove plant Barringtonia racemosa].
OBJECTIVE
To study the chemical constituents of mangrove plant Barringtonia racemosa.


METHODS
Chemical constituents from the ethyl acetate extract of the stem bark of this plant were isolated by silica, Sephadex LH-20 column chromatography and identified by NMR analysis.


RESULTS
Five compounds were isolated and identified. They are 3,3'-dimethoxy ellagic acid (1), dihydromyticetin (2), gallic acid (3), bartogenic acid (4) and stigmasterol (5).


CONCLUSIONS
Compounds 1-3 were isolated from this plant for the first time.
