Dodecyl ferulate was synthesized by ferulic acid and dodecyl alcohol using tetraethyl titanate as cat-alyst, and the product was purified by macroporous adsorption resin. The optimal synthesis conditions were de-termined by orthogonal experiment as follows:molar ratio of ferulic acid to dodecyl alcohol 1∶5, reaction tem-perature 140℃, reaction time 10 h, catalyst dosage 4%. Under these conditions, the yield and purity of do-decyl ferulate were 81. 8% and 90% respectively. The evaluation result of DPPH method showed that dodecyl ferulate exhibited good DPPH free radical scavenging activity. The evaluation result of Schaal oven-storage method indicated that dodecyl ferulate had better antioxidant effect on siritch at the dose of 0. 04%.
