The extraction of sesamin was studied by microwave-ultrasomic wave aided ectraction.The effects of temperture,ration of the weight of sesamin to the volume of solvent and ultrasonic extraction time were investigoted in detail.Response surface methodology was applied to predict optimum conditions for microwave-ultrasomic wave aided extraction and extracted with organic solvent of sesamin.The results indicated that four effectiv factors on oid yield was in the order: extraction temperaturepower of ultrasoundextraction timeration of the weight of raw material to the volume of solvent.The optimum technological parameters were as follows: extraction time 33 min,ration of the weight of raw material to the volume of solvent was 1:15,extraction temperature 60℃ and power of ultrasound 330 W.Under the optimal extrating condition,the maximum extraction rate reach 56.56mg•g-1.
