| Abstract: | Pumpkin polysaccharide, which have health effects and disease treating functions, is the main active ingredients of a study of extracting pumpkin. In this paper, a study of extracting pumpkin polysaccharide from pumpkin under ultrasound irradiation with water as solvent is made. Effects of premarinating time, ultrasound power, time and on/off ratio of ultrasonic irradiation on pumpkin polysaccharide extraction are investigated. Experiments show that taking 10 rain premarinating time at 60℃, 80W ultxasound power and 20 minutss of ultrasound processing time with on/off ratio being 1, the maximum extraction yield （42.6 mg/g） can be obtained. |
