[目的]优化新疆枸杞多糖的提取与脱色的工艺条件.[方法]采用单因素试验和正交试验,研究影响枸杞多糖得率的4个因素,确定枸杞多糖提取的最佳工艺条件；采用单因素试验,确定大孔树脂型号,研究影响枸杞多糖脱色的3个因素,确定枸杞多糖溶液脱色的最佳条件.[结果]多糖提取试验中,影响枸杞多糖得率的因素顺序为浸提温度＞浸提时间＞浸提次数＞料液比；最佳提取条件为:料液比1∶20,浸提温度80℃,浸提次数3次,浸提时间3h.糖溶液脱色试验中,AB-8大孔树脂的脱色效果最好；温度是影响多糖溶液脱色的主要因素,其次为料液比和脱色时间；最佳脱色条件为:温度60℃,料液比1∶7,脱色时间3h.[结论]该研完为枸杞资源的开发利用提供参考数据.%[ Objective] The study aimed to optimize the technology conditions for the extraction and decolouration of the polysaccharide from Lycium barbarian in Xinjiang. [ Method] The single factor experiment and orthogonal test were used to study 4 factors influencing the yield of the polysaccharide from L barbarum and confirm the optimum technology conditions for extracting the polysaccharide from L barbarian. The single factor experiment was used to determine the model of the macroporous resin,study 3 factors influencing the decolouration of the polysaccharide from L barbarum and confirm the optimum conditions for the decolouration of the polysaccharide solution from L barbarum. [ Result] In the polysaccharide extraction test, the effects of 4 factors on the yield of the polysaccharide from L. Barbarum were in order of extraction temperature > extraction time > extraction times > ratio of material to liquid; the optimum extracting conditions were as follows: the material-liquid ratio of 1 :20,extraction temperature of 80 ℃. Extraction times of 3 and extraction time of 3 h. In the decolouration test of the polysaccharide solution, AB-8 macroporous resin got best the decolouration effect; the temperature was the main factor to influence the decolouration of the polysaccharide solution from L. Barbarum and followed by the material - liquid ratio and decolouration time; the optimum decoloration conditions were that the decoloration temperature was 60 ℃. ,the material-liquid ratio was 1 :7 and the decoloration time was 3 h. [ Conclusion ] The study provided the reference data for the development and utilization of the L barbarum resource.
