| Abstract: | In this paper the optimization of extraction method of total total flavonoids from rock candy navel orange peels was obtained by microwave technique.the yiled of total flavonoids was used as evaluated index and determined by using.The optimum condition were obtained by orthogonal experiment as follows:the ratio of solid/liquid 1∶10,alcohol concentrations 60%,microwave irradiation time 5 min,microwave output power 350 W and NaOH content 1%.Under this condition the extraction yield was 6.11% and RSD was 0.43%(n=3) .Compared to traditional extraction methods,microwave had the advantages of reducing extraction time,simple procedure and improving yield. |
