Using liquid-solid ratio, ultrasonic time, ultrasonic temperature, and ultrasonic power as factors, we optimized the ultrasonic-assisted extraction process of polysaccharides from Lycium ruthenicum Murr.by response surface methodologies on the basis of single-factor experiments.The optimal extraction conditions can be determined as follows: the liquid-solid ratio of 20∶1(mL∶g),the ultrasonic time of 40 min, the ultrasonic temperature of 60 ℃,and the ultrasonic power of 180 W.Under above conditions, the extraction rate of polysaccharides from Lycium ruthenicum Murr.is 9.19%.
