| Abstract: | Selecting ethyl acetate as the extraction solvent, using soybean oil as raw material, the ultrasonic wave-assisted extraction conditions of stigmasterol from soybean oil were optimized through L9 （3^4） orthogonal experiments on the base of single factor. The results showed that the optimum conditions were as follows： ultrasonic temperature 50℃, ultrasonic time 40 min, ratio of liquid to material 19 mL/g, and under these conditions, the extraction rate can reach to 34.15%. |
