摘　　要：目的:研究超高压技术提取黄芪多糖的最优工艺。方法:以提取液中的总糖含量为指标,采用均匀设计法试验研究超高压技术工艺参数对黄芪多糖提取效果的影响。结果:超高压技术提取黄芪多糖最优操作工艺参数:提取压力350MPa,液固比60 mL/g,浸泡时间5 h,保压时间为2 min,提取率能达到24.2%。结论:超高压技术提取黄芪多糖与其他方法相比较,具有提取率高,提取液杂质少,容易分离纯化,提取时间短,耗能低等特点。AIM： To study the optimum technological parameters fo ultra-high pressure extraction. METHODS： Measured concentration of r extraction of Astragalus polysaccharides by total astragalus polysacharides served as the marker, the design of uniform distribution was applied to evaluating the ultra-high pressure extration efficiency in comparison with reflux and ultrasonic extraction efficiency. RESULTS： The optimal parameters of ultra-high pressure extraction was as follows： 350 MPa pressure,60 mL/g ratio of solvent to solid material,5 h soaking time, 2 min extraction time. Under the conditions, the high yield was up to 24.2 %. CONCLUSION ： Ultra-high pressure extraction has a series of advantages, such as higher yield, less impurity, easier separation-purification, shorter extraction time and lower energy input.
