The rice bran wax was firstly extracted by solvent from rice bran, and triacontanol was thenextracted after refining. The extraction conditions were determined through the investigation of solvent type, extraction temperature, time and other factors. After refining, the optimum conditions for extracting triacontanol were determined, and the corresponding products were characterized by infrared spectroscopy. The experimental results show that the yield of crude rice bran wax is 1.0%~1.5% under the conditions of isobutanol as extractant, isobutanol/rice bran mass fraction ratio of 10, extraction temperature of 105 ℃ and extraction time of 5 h. In addition, the yield of refined rice bran wax is 3.1% under the conditions of saponification temperature 55 ℃, reaction time 8 h, sodium hydroxide concentration 3 mol/L and ethanol calcium chloride as extraction solution. The infrared spectrum analysis indicated that the melting point of the product is 85.0~86.5 ℃.
