摘要
采用单因素实验和正交实验法,进行了微波辐射萃取补阳还五汤多糖的最佳工艺条件研究。探讨了不同微波辐射时间、微波功率及料液比等条件对多糖得率的影响。结果表明,在微波辐射时间20min,微波功率325W,料液比为1:7,补阳还五汤中多糖得率为7.75%。微波辅助萃取大大缩短了提取时间,节省了溶剂,提高了收率。
The optimum extracting condition for polysaccharides from Bu-yang-huang-wu-tang by microwave-assisted extraction （MAE）was studied using single factor experiment and orthogonal method. The MAE conditions, such as the extraction time, microwave power and liquid-solid radio were all studied to obtain maximum extraction rate. The most suitable conditions for the extraction were shown as follows： the extracting time was 20 min, the microwave power was 325 W, and liquid-solid radio was 1 ： 7, and the extraction rate of polysaccharides came to 7.75%. Compared with direct heating extraction, MAE can shorten the extracting time, reduce the consumption of solvent and improve yield of polysaccharides.
