【摘要】 采用热水浸提法从枸杞干果中提取枸杞多糖,经正交实验确定浸提时间、温度、料水比最优值分别为:5h、100℃、1∶40;微波预处理超过25min时,多糖得率达15.91%;醇沉时当醇沉时间为4h、乙醇加入量为4倍时有利于枸杞多糖提取。更多还原

【Abstract】 Lycium barbarum polysaccharide were extracted by the methods of water extracting,and the optimum extraction technology was determined by orthogonal experiments.The optimum parameters to extract were as follows: the extracting time 5h,temperature 100℃,ratio of water to material 1∶40;With microwave-assisted extraction for over 25 minutes,the extraction percent will reach 15.91%;Extraction concentrated to proper volume was precipitated with 4 times volume of 95% ethanol for 4 hours.更多还原
