摘要
以经石油醚和95%乙醇处理过的榛子叶粉为原料,主要研究微波辅助提取榛子叶多糖的工艺条件。分别考察了浸提温度、浸提时间、料液比、微波处理时间对榛子叶多糖得率的影响,并采用L9(3^4)正交试验优化提取工艺,最后得出的最佳提取工艺条为:浸提温度为60℃,浸提时间为2h,料液比为1:25(W:V),微波处理时间为3min,此条件下榛子叶多糖得率为2.67%。
With petroleum ether and 95% ethanol treated hazelnut leaf powder as raw material, microwave-assisted extraction of hazelnut leaf polysaccharide was studied. The impact of leaching temperature, leaching time, the solid- liquid ratio and microwave processing time on polysaccharide yield of hazelnut leaf were investigated. As the result, the optimum conditions obtained by L9(3^4) orthogonal experiment were as follows: leaching temperature was 60 ℃, leaching time was 2 h, solid-liquid ratio was 1 :25 (w : V), microwave processing time was 3 min. Under the above conditions, the polysaccharide yield of hazelnut leaf was 2. 67%.
