摘 要:以水苏糖提取率为指标,采用热水浸提法从地参中提取水苏糖,使用单因素正交法优化提取工艺,得到最佳提取工艺为料液比1∶22.5(g∶mL),浸提时间3.5 h,重复次数2次,浸提温度65℃,此时水苏糖提取率为32.34%。同时检测水苏糖对DPPH自由基和ABTS自由基的清除能力,结果得出水苏糖具有较好的抗氧化活性。In this study,the extraction rate of stachyose was taken as the index,the hot water extraction method was used to extract stachyose from the Lycopus lucidus Turcz,and the extraction process was optimized by single factor orthogonal method,and the optimal extraction process was obtained as the solid-liquid ratio of 1∶22.5(g∶mL),the extraction time was 3.5 h,the number of repetitions was 2 times,the extraction temperature was 65℃,and the extraction rate of stachyose was 32.34%.The scavenging ability of stachyose on DPPH free radicals and ABTS free radicals was tested,and the results showed that stachyose had good antioxidant activity.
