Study the optimum extraction of ferulic acid in rice bran to the market for the purpose of industrialization. In univariate and multivariate tests based on orthogonal test, and then comprehensive selection of environmentally friendly reagents, under the simple operation and reduce energy consumption, the analysis of optimum extraction process. Best ferulic acid extraction process are:raw materials using ethyl acetate and ethanol (2∶1 by volume) mixture of liquid solvent degreasing class three times,skimmed class ratio up to 9.43%. The reaction was then extracted at a temperature of 60℃in 3.5 mol/L NaOH solution in 2.5 h,dropping concentrated hydrochloric acid ferulic acid precipitation, the mass fraction of crude ferulic acid obtained as follows:89.80%, raw materials ferulic acid extraction rate:0.77%. In the whole process is environmentally friendly reagents,easy operation and low power consumption conditions, but also to obtain a higher yield. The method is suitable for the extraction process of industrialization ferulic acid.
