以蛹虫草菌皮为材料,研究虫草多糖和虫草素的提取工艺,通过单因素正交试验考察了提取温度、提取时间、料液比及提取次数4个因素对虫草多糖和虫草素提取率的影响,建立了提取虫草多糖及虫草素的最佳工艺,即优化条件为:提取温度100℃,提取时间2 h,料液比1∶10,提取次数2次,此时虫草多糖提取率可达8.72%,虫草素的提取率达到0.2908%。 Using Cordyceps militaris as material, the extraction process of polysaccharide and cordycepin was studied. The extraction rate of Cordyceps polysaccharide and cordycepin was studied by single factor orthogonal test, including extraction temperature, extraction time, the ratio of solid to liquid and the number of extraction The optimum conditions for the extraction of polysaccharides and cordycepin were established. The optimal conditions were: extraction temperature 100 ℃, extraction time 2 h, ratio of material to liquid 1:10 and extraction times 2 times, the extraction rate of polysaccharide from Cordyceps was up to 8.72%, cordycepin extraction rate of 0.2908%.
