Study on extraction of flavonoids from orange peel

Fan Ting-ting

Abstract

The optimum extracting conditions of flavonoids from orange peel were obtained by using single factor and orthogonal experiment design.The content of flavonoids was determined.The result shows that 70 ℃ of water-bath temperature,1∶40 of ratio of solid material to 70% ethanol solution,and two-hours extraction time are the optimal conditions under which flavonoids in orange peel is 1.68%.
