Abstract
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). CONCLUSION: Compounds 1-3 were isolated from this plant for the first time.
