To investigate the secondary metabolites of the mangrove plant Ceriops tagal. Column chromatography techniques including HPLC were used for the separation and purification, and extensive spectral analysis including various 2D NMR spectra were employed for structure elucidation. Nine compounds, namely, tagalsins A (1), ent-5alpha-dolabr-4 (18) -ene-15S,16-diol (2), squalene (3), betulinic acid (4), lup-20 (29) -en-3-on-28-oic acid (5), betulin (6), lup-20 (29) -en-3-on-28-ol (7), beta-sitosterol (8), n-hexacosanylferulate (9) were obtained. Of which 1 and 2 belong to dolabrane diterpene. Compound 1 is a new compound, and 2 to 9 are isolated from this species for the first time.
