Optimization of Extraction of Phenols From Leaves of Oak Tree by Response Surface Methodology

摘要：

The extraction of polyphenols from leaves of oak tree was optimized to maximize phenol extraction, Y. A central composite design involving ethanol concentration (X1), extraction temperature (X2), extraction time (X3) and ratio of liquid to solid (X4) was used, and second-order model for Y was employed to generate response surfaces. The optimum conditions for phenol extraction (Y) were X1=52.17％; X2=58.13 ℃; X3=20 min; X4=31.64. Estimate of Y at the optimum was 92.9％. Experimental verification gave values of Y=93.65％.
