摘　　要：试验使用氢氧化钠溶液调节纯水pH,得到pH为10的碱性水为提取溶剂,以热浸提方法提取柑桔皮渣中类黄酮。在单因素试验的基础上,利用三元二次旋转组合试验设计及响应面分析法,优化热浸提时间、温度及料液比,建立此3因素与类黄酮得率之间的数学模型。经试验确定碱性水提取柑桔皮渣中类黄酮的最佳工艺条件为:热浸提时间为2.2h、料液比为1:12(g/mL)、提取温度为64.6℃。在此最佳工艺条件下,类黄酮的得率为0.115%。In this study,the pure water pH was regulated by sodium hydroxide solution.The extract solvent is pH10 basicity of water and flavonoids were extracted from citrus peels by heat leaching method.On the basis of single-factor test,the mathematical model was established on the heat leaching extract time,temperature and solid-liquid ratio through orthogonal regression of ternary quadratic and response surface methodology.According to this optimum process model,the extraction rate of flavonoids is 0.115% in the condition of heat leaching extract time：2.2 h,temperature：64.6 ℃ and ratio of material to water 1：12.
