| Abstract: | On the basis of single-factor tests, Design Expert 7.0.0-statistical analysis software was adopted to build a quad- ratic regression equation with chlorogenic acid yield as function, and extractability of chlorogenic acid as the response value, and then the response surface and contour were plotted. According to the results from the above studies, the optimum conditions for the microwave-assisted extraction of chlorogenic acid were obtained： the solvent to material ratio （mL ： g） was 31, volume fraction of the ethanol was 70%, the power of the microwave 495 W, microwave time 30 s, and the extraction temperature was 60 ~C. Under these conditions, the chlorogenic acid yield was up to 14.47 mg/g. |
