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.
目的
研究红树植物总状花八宝树的化学成分。
方法
采用硅胶柱色谱、Sephadex LH - 20柱色谱法从该植物茎皮的乙酸乙酯提取物中分离化学成分，并通过核磁共振分析进行鉴定。
结果
分离鉴定出5种化合物。它们分别是3,3'-二甲氧基鞣花酸（1）、二氢杨梅素（2）、没食子酸（3）、八宝树酸（4）和豆甾醇（5）。
结论
化合物1 - 3首次从该植物中分离得到。
