The process for extraction of total sterols from Gardenia jasminoides seed by the ultrasound technology was studied.The effects of different solvents,amount of solvents,extraction time,extraction times,extraction time and ultrasonic power were explored.Orthogonal experiment result showed that the optimum conditions were 100W, petroleum ether as extracting agent,the ratio of material to solvent 1∶8( W/V) ,extracting one time and 25min for ultrasound extraction.Under optimum conditions,the extraction yield of gardenia sterol was 3.12mg /g.
