Abstract: Based on one-factor-at-a-time experiments, response surface methodology was used to optimize the ultrasonic-assisted extraction of polysaccharides from Actinidia arguta fruits wildly growing in Changbaishan Mountain. The optimal extraction conditions were found as 25:1 of distilled water-to-Actinidia arguta fruit (mL/g), 92 W of ultrasonic power, and 46 ℃ of extraction temperature. Under these conditions, the extraction yield of polysaccharides was 4.80%. In conclusion, response surface methodology can provide a reliable approach to find optimal conditions for the extraction polysaccharides from Actinidia arguta fruits.
