摘要
以多糖得率为考察指标,采用响应曲面法(response surface methodology,RSM)和中心组合设计,以二次提取的pH、微波功率、萃取温度和提取时间作为优化因子,对五味子粗多糖的微波辅助-半仿生提取工艺条件进行优化研究。试验结果表明,二次提取的pH分别为4.5和9,微波功率600W,提取时间7.0min,萃取温度60℃,在此条件下辽五味子多糖的提取率为14.697%,高于传统的水提醇沉法。
In this paper,using the extraction rate of polysaccharides as a reference,the optimum conditions for the extraction of polysaccharides from Schisandra chinensis（Turcz.）Bail fruits by microwave-assisted semi-bionic extraction method were obtained through response surface methodology（RSM） and central-composite design（CCD）.The effects of the extraction rate,solution＇s pH,microwave power,time,temperature on the extraction rate of polysaccharide were examined.The optimum conditions are as follows：the first and second extraction solution＇s pH 4.5 and 9.0 respectively,mi crowave power 600 W,extraction temperature 60 ℃ and extraction time 7.0 min.The yield of polysaccharides was 14.697%,which was higher than the old data obtained by traditional water extraction method.
