摘要	Ultrasonic-assisted extraction (UAE) of polysaccharides from Piteguo fruit (Pyrus sinkiangensis) was studied. The four parameters, i.e., ratio of water to raw material, extraction time, extraction temperature, and ultrasonic power were optimized by the Box-Behnken design (BBD). The structure of polysaccharide from Piteguo (PTGP) was analyzed preliminarily by infrared spectrum. Antioxidant activities of PTGP were detected in vitro. The results indicated that the extraction ratio of crude PTGP was up to 5.16% +/- 1.81% under the optimized extraction conditions as follows: ratio of water to raw material 13:1 mL/g, extraction time 66 min, extraction temperature 70 degrees C and ultrasonic power 230 W, which is was well matched with the value (5.25%) predicted by the BBD model. Spectroscopic studies illustrated PTGP was composed of Glc with (beta-type pyranoid type sugar ring. Moreover, the results of antioxidant activity assay indicated that PTGP has antioxidant effect in a certain extent, and could be used as a potential natural antioxidant.
