【摘要】 用微波提取技术从粪鬼伞(Coprinus sterqulinus Fr)菌丝体干粉中提取粪鬼伞多糖。在单因素试验的基础上,依据响应面分析法,研究了微波功率、提取时间和料液比对粪鬼伞多糖提取率的影响,确定微波提取粪鬼伞多糖的最佳工艺参数为:微波功率637W、提取时间3min、料液比为1:23,粪鬼伞多糖的提取率为14.39%。更多还原

【Abstract】 The microwave extraction technology was used to extract Coprinus sterqulinus Fr polysaccharides (CPS) from the dried powder of Coprinus sterqulinus Fr.On the basis of single-factor experiments,the microwave power,extracting time and the ratio of liquid to solid were optimized according to the mathematic model built by Central Composite Design in Design Expert Software on the rationale of response surface methodology.The optimum microwave extraction technology is as follows:the microwave power 637W,extracting time 3min,the ratio of solid and liquid 1:23.In this condition the extracting rate of polysaccharide was 14.39%.更多还原
