摘　　要：采用超声波辅助提取技术,考察了料液比、80℃热水浸泡时间、超声时间、超声功率四因素对短毛柽柳花、嫩枝叶、茎中多糖提取率的影响。本实验条件下,短毛柽柳不同部位多糖提取的最佳工艺条件为:料液比1:60,热水浸泡时间1h,超声时间20min,超声功率300W。此时花、嫩枝叶、茎中多糖含量分别为53.06、164.90、48.01mg/g,嫩枝叶的多糖含量明显高于其他两个部位。此方法回收率为98.25%。In this study, ultrasonic is used to extract polysaccharides from different parts of Tamarix karelinii Bge..The effects of raw material to hot water ratio, soaking time in hot water, ultrasonic treatment time and power on extraction rates of polysaccharides from flowers, young leaves and stem of Tamarix karelinii Bge. were investigated. Based on the results of single factor test, orthogonal test was designed to optimize these factors. The results showed that the contents of polysaccharides in the extracts o...
