Title: Microwave-assisted extraction of chlorogenic acid from sunflower seed kernel
Abstract: The chlorogenic acid was extracted by microwave-assist from sunflower seed kernel,and its content was determined by ultraviolet spectrophotometric method.The influences of microwave power,time and ratio of material to liquid on determination results were studied,and the microwave-assisted extraction method was compared with the traditional method of heat reflux extraction.The results showed that the optimal conditions of microwave-assisted extraction were as follows:ratio of material mass to liquid volume 1∶20,microwave power 440 W,time 7 min.No significant difference was observed between the microwave method and the traditional method.The microwave-assisted extraction was a quick,accurate and convenient method.
