| 摘 要： | 为优化超声波辅助提取武夷岩茶总黄酮,采用响应面法优化固液比（X1）、乙醇浓度（X2）、提取温度（X3）和提取时间（X4）,分析并建立数学模型。结果表明:固液比、乙醇浓度、提取温度和提取时间对总黄酮的提取率均有显著影响（p<0.01）;回归方程为Y=1.407+0.0375X1+0.0992X2+0.153X3+0.133X4-0.0251X12-0.0439X22-0.0751X32-0.0664X42+0.0288X1X2+0.03X1X3-0.0338X2X3-0.0613X2X4;最佳的提取工艺参数为液固比21∶1,乙醇浓度80%,提取温度70℃,提取时间50min,此工艺条件下岩茶中总黄酮的提取率为1.605%±0.012%,与模型预测值吻合,说明所建立的模型切实可行。 |

| Abstract: | In order to optimize ultrasonic-assisted extraction of flavonoids from Wuyi Rock tea,response surface methodology was used to establish models for optimization of solid-to-liquid ratio(X1),ethanol concentration(X2),extraction temperature(X3)and extraction time(X4). Results showed that solid-to-liquid ratio,ethanol concentration,extraction temperature and extraction time had significant affects on extraction rate of flavonoids(p<0. 01).Regression equation was Y=1. 407+0. 0375X1+0. 0992X2+0. 153X3+0. 133X4-0.... |
| Keywords: | ultrasonic-assisted extraction Wuyi Rock tea total flavonoids response surface methodology optimization |
