| Abstract: | The content of ferulic acid was analyzed by HPLC after being extracted by alkaline-alcohol hydrolysis from rice bran. The extraction content was influenced by concentration of sodium, sodium hydroxide/ethanol ratio, hydroxide temperature, extraction time, and solid/liquid ratio, which was investigated by the uniform experimental design method. The optimum conditions were as follows： concentration of sodium was 1.3 %, sodium hydroxide/ethanol ratio was 5.6 ： 1, hydroxide temperature was 83.2 ℃, extraction time was 2.8 h, solid/liquid ratio was 1 ： 9.4, the maximum yield of ferulic acid was 514 mg/100g. |
