چکیده
|
Summary: the extraction of flavonoids from grape leaves was optimized to maximize flavonoids yield in this study. a central composite design of response surface methodology involving extracting time,power,liquid-solid ratio,and concentration was used,and second-order model for y was employed to generate the response surfaces. the optimum condition for flavonoids yield was determined as follows: extracting time 24.95 min,power 72.05,ethanol concentration 63.35%,liquid-solid ratio 10.04. under the optimum condition,the flavonoids yield was 76.84 %.
