摘　　要：本文以籽瓜作为实验的主要材料,运用超声波辅助提取法将籽瓜多糖提取出来,通过温度、时间、料液比、功率等单因素实验找出籽瓜多糖最大提取率的工艺参数。对修改后的工艺参数进行检测发现,籽瓜多糖提取率最大值为6.32%;以Vc作对照,对籽瓜多糖进行抗氧化活性分析,结果显示,当籽瓜多糖的浓度达到0.08 mg/mL时,对DPPH自由基和羟自由基的清除能力达到Vc的一半,这表明SMP具有一定的抗氧化活性。This article uses seed melon as the main experimental material and employs an ultrasonic-assisted extraction method to extract polysaccharides from the seed melon.By conducting single-factor experiments on temperature,time,solid-liquid ratio,and power,the optimal process parameters for the maximum extraction rate of seed melon polysaccharides are determined.The detection of the modified process parameters revealed that the maximum extraction rate of seed melon polysaccharides was 6.32%.Using vitamin C(Vc)as a control,the antioxidant activity of seed melon polysaccharides was analyzed.The results showed that when the concentration of seed melon polysaccharides reached 0.08 mg/mL,their scavenging ability for DPPH radicals and hydroxyl radicals was half that of Vc,indicating that seed melon polysaccharides possess certain antioxidant activity.
