摘　　要：为优化玫瑰花花色苷提取工艺,在单因素实验基础上,选择超声波功率、酸性乙醇溶液浓度、超声波温度、超声波时间为自变量,花色苷提取率为响应值,利用Box-Benhnken中心组合实验和响应面分析法,研究各自变量交互作用及其对花色苷提取率的影响,模拟得到二次多项式回归方程的预测模型,并确定玫瑰花花色苷提取工艺:超声波功率500W,酸性乙醇溶液浓度55%,超声波温度40℃,超声波时间40min,在此条件下,玫瑰花花色苷提取率可达6.24mg/g干质量。To optimize the anthocyanin extraction from roses, On the basis of single-factor test, the mathematical regression model was established about the dependent variable （extraction rate of anthocyanin from roses） and independent variables（the power of ultrasonic, the concentration of acidic ethanol solution, the temperature of ultrasonic,the time of ultrasonic）through Box-Benhnken center composite design and response surface methodology. The optimum extraction conditions as follows： the power of ultrasonic 500 W, the concentration of acidic ethanol solution 55%, the temperature of ultrasonic 40 ℃, the time of ultrasonic 10 min. Under these conditions, the extraction rate of anthocyanin from roses was 6.24 mg/g.
