Abstract
The method of ultrasonic-assisted extraction (UAE) was used to extract Coix see from Coix lachrymajobi L .Conditions including the extraction solvents ,time and temperature of ultrasonic treatment ,the ratio of material and solvent ,and particle size were investigated for ef-fective recovery of fatty oils from coix seed .Optimum conditions of UAE of coix seed oil can be concluded that using ethanol as solvent in the experiment ,the duration of ultrasonic is 40 min at 60℃ ,the solvent to material ratio was 1∶3 .5 ,and the particle size was 60 meshes .The yield of Coix seed oil was 11 .8% .The ultrasonic extraction saves a lot of time ,but gives the high extrac-tion rate .关键词
