中文摘要：
目的研究红树林植物海榄雌Avicennia marina枝、叶的化学成分。方法采用硅胶柱色谱、葡聚糖凝胶SephadexLH-20柱色谱、HPLC等方法分离纯化，通过现代波谱技术鉴定其结构。结果从海榄雌枝、叶的提取物中分离获得10个化合物，鉴定结构分别为acteoside（Ⅰ）、isoacteoside（Ⅱ）、syringaresinol（Ⅲ）、5，7-二羟基-3’，4’，5’-三甲氧基黄酮（Ⅳ）、3吲哚甲酸（Ⅴ）、白桦酸（Ⅵ）、白桦醇（Ⅶ）、羽扇豆醇（Ⅷ）、白骨壤醌C（Ⅸ）和山柰酚（Ⅹ）。结论化合物Ⅰ～Ⅵ为首次从该植物中分离得到。
英文摘要：
Objective To investigate the chemical constituents in the aerial parts of mangrove plant Avicennia marina. Methods The isolated compounds Ⅰ - Ⅹ were obtained by the combination of silica gel, Sephadex LH-20 column chromatographies and by semi-preparative HPLC separation. Structural elucidation was conducted by the modern spectral method. Results Ten compounds were isolated and identified from the aerial parts of A. marina, including acteoside （ Ⅰ ）, isoacteoside （ Ⅱ ）, syringaresinol （ Ⅲ ）, 5, 7-dihydroxy-3＇, 4＇, 5＇-trimethoxyflavone （ Ⅳ ）, indolyl-3-carboxylic acid （ Ⅴ ）, betulinic acid （Ⅵ ）, betullin （Ⅶ）, lupeol （Ⅷ）, avicequinone C （Ⅸ）, and kaempferol （Ⅹ）. Conclusion Compounds Ⅰ -Ⅵ are isolated from A. marina for the first time.
