摘要
采用超声波辅助水提取法对枸杞叶、无花果叶多糖进行提取。通过正交试验，最终确定多糖提取的最佳工艺条件为：提取温度80℃、料液比1：50、提取时间50min。制得枸杞叶、无花果叶粗多糖的提取得率分别为15，30％、11．82％。并且采用苯酚一硫酸光度法对多糖进行测定枸杞叶多糖含量为10．23％，无花果叶多糖含量是8．53％。
Abstract
The ultrasonic method was used in polysaccharide extraction from Lycium barbarum leaves and Ficus carial leaves. The optimal extraction conditions of polysaccharide were extraction temperature of 80℃, the solid-liquid ratio 1 ： 50, the extraction time 50 min, which were drawn through orthogonal experiments. The extraction rates of polysaccharide were 15.30% and 11.82% respectively. Using sulfuric acid and phenol method in the determination of crude polysaccharides, the polysaccharide content from the Lycium barbarum leaves was 10.23% and the polysaccharide content from theficus carial leaves was 8.53%.
