摘　　要：先用微波对灵芝进行预处理,改变灵芝的组织结构,然后用碱溶液提取灵芝中的灵芝多糖,并与传统的提取方法进行比较。采用单因素试验法,考察润湿时间、乙醇用量、乙醇浓度、微波功率以及微波辐射时间对灵芝多糖提取率的影响。确定优化的提取工艺参数为:润湿时间60 min、乙醇用量30 mL、乙醇浓度70%、微波功率700 W、微波辐射时间70 s。结果表明微波预处理提取法的提取时间比传统方法缩短40%,灵芝多糖的提取率提高34.2%。The method of microwave pretreatment is taken in this paper,which use microwave radiation to destroy tissue structure of ganoderma lucidum before extraction of Polysaccharides with alkaline medium,is compared with the traditional one.Its parameters,such as soaking time,quantity of ethanol,ethanol concentration,microwave power,microwave radiation time,were analyzed by single-factor tests.The optimum pretreatment conditions are soaking time 60 minutes,quantity of ethanol 30 mL,ethanol concentration 70 %,microwave power 700 W,microwave radiation time 70 seconds.The results show that the extracting time has been shortened by 40 % than the traditional one,while it＇s extracting ratio has been improved by 34.2 %.
