Title: The Microwave-assisted Extraction of Chlorogenic Acid from Sunflower Leaves
Abstract: Taking the rate of extracting chlorogenic acid as target,every factor that may influence extracting chlorogenic acid from sunflower leaves by microwave-assisted extracting is studied.The result shows that the extraction yield of chlorogenic acid can reach to 1.848% when ethanol concentration 70%,ratio of the material to liquid 1∶20,immersion in water for 30 min, microwave temperature 60 ℃,power 300 W,microwave time 6 min,extraction temperature 70 ℃,extraction time 20 min, and pH value 7.In order to supply some reference for the industrial extraction of chlorogenic acid from sunflower leaves by analyzing the elaborate factors.
