Abstract: Objective To study the chemical constituents from mangrove Excoecaria agallocha.Methods The chemical constituents were separated and purified by chromatographic methods after solvent extraction and were identified by spectroscopic analyses (EI-MS,1D NMR).Results Twelve compounds were isolated from this plant and identified as:14-taraxeren-3-one(Ⅰ),dibutyl phthalate(Ⅱ),β-amyrin (Ⅲ),18-oleanen-3-ol(Ⅳ),18-oleanen-3-one(Ⅴ),phaeophytin A(Ⅵ),betulin(Ⅶ),β-rosasterol(Ⅷ),β-sitosterol (Ⅸ),betulinic aicd (Ⅹ),oleanolic acid (Ⅺ),ursolic acid (Ⅻ).Conclusion Compounds Ⅶ,Ⅷ,Ⅹ,and Ⅻ are isolated from this plant for the first time.
