Title: Extraction of Flavonoids from Reed Leaf by Microwave Technology
Abstract: The effects of the liquid-material ratio,the extraction time,the pressure and the microwave power on the extraction of flavonoids from reed leaf were studied.Orthogonal test showed that the best extraction regent,liquid-material ratio,microwave power,extraction time and pressure were 70% ethanol,30:1,600 W,13 min and 1.4 MPa,respectively.Under those conditions,the extracting rate of flavonoids was 1.46%.Microwave extraction technology of flavonoids from reed leaf was better than other technologies,due to the higher yield rate and shorter extraction time.
