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.
