摘要
通过正交实验对热水浸提法和微波提取法提取枸杞多糖进行了比较研究。热水浸提法提取枸杞多糖的最佳工艺条件为:提取温度70℃、提取时间4h、料液比1∶20(g∶mL)、提取次数3次,提取率为4.51%;微波提取法提取枸杞多糖的最佳工艺条件为:微波功率560W、微波时间90s、料液比1∶10(g∶mL)、提取次数3次,提取率为5.91%。微波提取法时间短、能耗小、提取溶剂用量少、提取率高,优于热水浸提法。
The comparative study on hot water extraction method and microwave extraction method for Ly-ciurn barbarum polysaccharide was conducted through orthogonal experiment. Under the optimum conditions of hot water extraction as follows.extraction temperature 70 ℃ ,extraction time 4 h,solid-liquid ratio 1 ： 20（g ：mL）, and extracting for three times,the extraction rate of polysaccharide was 4.51%. Under the optimum con- ditions of microwave extraction as follows：microwave power 560 W, microwave irradiation time 90 s, solid-liquidratio 1 ：lO（g： mL）, extracting for three times, the extraction rate of polysaccharide was 5.91%. Microwave extraction method was superior to hot water extraction method for it cost less time, energy and extraction sol- vent with higher extraction rate.
