摘要
研究了超声波辅助提取玉米秆多糖的最佳工艺及其抗氧化性。结果表明,超声波辅助提取玉米秆多糖的最佳提取工艺参数为:料液比1:50、超声波温度50℃、超声波功率250 W、超声波时间15 min。玉米秆多糖对□OH和O2□清除作用明显,具有较好的还原力,表明玉米秆多糖具有较好的抗氧化活性。
Optimum ultrasonic-assisted extraction technology of polysaccharides from maize straw and an-tioxidant activity of the extract were studied. According to orthogonal design, the optimum condi-tions for the extraction of polysaccharides were as follows: solid-solvent ratio of 1:50, ultrasonic temperature of 50?C, ultrasonic power of 250 W, and ultrasonic time of 15 min. The fact that maize straw polysaccharides exhibited strong scavenging effects against □OH and O2□ and excellent reducing power demonstrates good in-vitro antioxidant activity of maize straw polysaccharides.
