Abstract: Chemical constituents of the n-hexane extract of the Hainan mangrove,Ceriops tagal,were investigated.Compounds 1 and 2 were isolated and purified by silica gel,RP C-18 column chromatography and preparative HPLC.Based on the spectroscopic data(HR-ESI-MS,1D NMR,2D NMR),these compounds were identified as two new dolabranes,and named as tagalditerpenes D and E.

Key words: mangrove, Ceriops tagal, dolabrane, tagalditerpene D, tagalditerpene E
