摘　　要：对葛根的快速提取工艺方法进行了考察,为工业化生产提供可靠的实验数据和理论依据。采用正交实验设计提取方法,HPLC法测定葛根素含量。最佳提取工艺为A2B2C3;影响因素的大小依次为:料液比、脉冲数、电场强度。此法提取葛根中的葛根素达1.91%,得膏率达8.32%。提取工艺可行,经济、省时、回收率高。a method of rapid extract technology was investigated in the root of kudzu vine,and it provided the reliable experimental and the theoretical basis for the industrious production.Method： the puerarin content was detected by HPLC,using orthogonal experimental design.Result： the best extracting technology is A2B2C3 for the puerarin;the influence factor in size is high voltage,impulsion frequency,and the ratio for the material to the liquid.puerarin rate in liquid up to 1.91% in the root of kudzu vine;and the extract ratio to the liquid is 8.32%.Conclusion： the extracting technology is feasible,economic with high recovery ratio and save time in the process.
