摘　　要：本实验通过正交试验探讨了白刺多糖的最佳提取工艺。在多糖提取之前先将白刺果肉、果皮粉末除脂,去除单糖等干扰因素。实验结果表明:白刺多糖的最佳提取工艺是料液比为1:5,94℃下回流提取3次,每次2h。在此条件下得到的白刺多糖含量为34.562mg/g。In this research, the optimum extracting conditions ofNitraria polysaccharide were investigated by orthogonal test. Lipid and monosaccharide were removed before the extraction of poiysaccharide. The results showed that under the conditions 94 ℃, 1：5（W/V）, extracting 3 times and 2 h for each time, the content of polysaccharide is 34.562 mg/g.
