In this experiment, we use Lycium barbarums as research materials to extract lycium barbarum polysaccharide by ultrasound-assisted. The effect of temperature, ratio of feed liquid, time and ultrasonic power on the yield of polysaccharide is studied, and the monosaccharide composition of LBP is analyzed by GPC-LLS. Based on the single factor experiment, the orthogonal design shows that the best conditions as follows: temperature is 75℃, the ratio of material to liquid is 1:20, the time is 2h and ultrasonic power is 200W, respectively.And under this conditions, the yield can rearch 11.03%. LBP is composed of Rha, Man, Glc and Gal. The molar ratio is 1︰1.66︰19.6︰3.98.
