Abstract:Objective To extract total flavonoids from wheat bran with microwave-aided extraction method.
Methods The optimal extraction technology of total flavonoids was defined by single factor and orthogonal tests.
Results The optimal extraction technology was as follows: microwave power of 560 W, microwave irradiation for
60 s, 80 % ethanol, the ratio of material to liquid of 1∶20. Under these conditions, the extraction rate of total
flavonoids was ‰. Conclusion The microwave-aided extraction is an economical and efficient method for the
extraction of total flavonoids from wheat bran.
