摘　　要：以绞股蓝为原料,通过单因素实验和响应面分析法对超声波辅助提取绞股蓝多糖的工艺进行优化。实验确定绞股蓝多糖提取的最佳工艺条件为:料液比1:47,超声波功率为129W,超声波时间和温度分别为52min、100℃,绞股蓝多糖得率可达3.24%。Gynostemma pentaphyllum was used as main materials,and extraction methods of polysaccharides from Gynostemma pentaphyllum were studied in this paper.The optimal extraction conditions of each method were determined by mono-factor experiment and response surface methodology（RSM） analysis.The results showed ultrasonic extration was the best method to extract the polysaccharides from Gynostemma pentaphyllum,and the optimal extraction condition as follows：ultrasonic time 52 min,ultrasonic power 129 W,and ultrasonic temperature 100 ℃,the ratio of solid to liquid 1：47.The yield of polysaccharides is 3.24% under these conditions.
