| Abstract: | The microwave-assisted extraction technology of chlorogenic acid olive leaves were optimized through quadratic regression orthogonal test based on the orthogonal test.The optimum technological conditions was as follows： extraction temperature was 61.71 ℃,alcohol concentration was 74.82%,pH=6,liquid to solid ratio was 30.50 mL/g,and extraction time was 25 min.Chlorogenic acid yield was 4.578 6 mg/g under the optimum conditions. |
