Ultrasonic extraction by water, ultra-filter separation and methodology process of lentinan were studied. The results showed that extraction rate increased, and extraction time, stock-extract ratio, viscosity of extract decreased; then concentration polarization of ultra-filter separation decreased, curing rate increased. Extraction rate of lentinan is 6. 62%, the main indexing are follows:2 h accessory ultrasonic extracted by water, 1 : 15( V : V) stock-extract ratio, 80 W ultrasonic power, 13 min cutting times. In view of economic effectiveness and methodology feasibility that ultrasound can decrease production load and cost.
