[Chemical constituents from the mangrove plant Ceriops tagal].
OBJECTIVE
To investigate the secondary metabolites of the mangrove plant Ceriops tagal.


METHODS
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.


RESULTS
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.


CONCLUSIONS
Compound 1 is a new compound, and 2 to 9 are isolated from this species for the first time.
