Aim: To study the chemical constituents of mangrove plant Aegiceras corniculatum, aiming at searching for new bioactive substances. Method: The EtOAc extract of Aegiceras corniculatum was subjected to repeated silica gel and Sephadex LH-20 column chromatography to afford nine compounds. The structures were elucidated on the basis of spectroscopic analysis. Results: Nine compounds were isolated and identified as falcarindiol (1), p-hydroxyphenethyl anisate (2), phthalic acid, bis (2-ethylhexyl) ester (3), 1-hentriacontanol (4), resveratrol (5), 1,5-dihydroxy-3-methoxy-7-methylanthraquinone (6), 1,3,5-trihydroxy-7-methylanthraquinone (7), quercetin (8) and lupeol (9). Conclusion: All the compounds were isolated from the plant for the first time. Compound 1 shows inhibitory activity towards PTP1B with the IC50 value of 9.15 ± 2.48 μmol·L-1.
