摘　　要：唇形科水苏属植物银条,也称银苗,药食两用,主产于偃师县(市),产量约有95%。本文以偃师产银条为原料,通过单因素、响应面分析法,研究了乙醇提取银条中水苏糖的最佳提取条件。以银条中水苏糖提取率为指标,通过单因素实验确定了银条水苏糖提取条件的参数范围,通过响应面分析法确定了其最佳提取条件。结果表明,最佳提取条件为乙醇浓度60%,液固比10:1,提取温度60℃,提取时间40 min,该条件下银条水苏糖提取率为46.8924%。Stachys floridana sehuttl, ex benth, also named yinmiao, a species of genus Stachys. And it is a special and traditional Chinese vegetable which can use as food and medicine. Yanshi city is the main origin with production over 95%. In this paper,the optimum extraction conditions of stachyose from yinmiao were studied by Response surface methodology （RSM）. The results showed that the optimum extraction conditions for stachyose yield from yinmiao were as follows：extraction temperature 60 ℃, extraction time 40 min, ethanol concentration 60%, and ratio of liquid-solid 10： 1. At these conditions, the yield of stachyose was 46. 8924%. In conclusion, RSM was successfully applied to determine the optimum extraction conditions for stachyose from yinmiao.
