摘要
研究了姬松茸液体发酵胞内多糖的提取条件,通过单因素实验、正交实验及极差分析确定的最佳提取工艺为:提取温度100℃、料液比1:30、提取时间3h、乙醇(95%)添加倍数3倍、提取次数2次,在此条件下粗多糖的提取率达6.64%。
The intracellular polysaccharides were extracted from Agaricus blazei Murill by submerged culture. The single factor tests, orthogonal experimental designs and range analysis were applied to optimize the extraction conditions. The optimum conditions were as follows: extracting temperature was 100℃, the ratio of water to sample was 30:1, extracting time was 3 hours, volume of 95% ethanol was 3 times and extracting times were 2. Under the conditions, the yield of crude polysaccharides was up to 6.64%.
