Abstract
Microwave-assisted extraction of total flavonoids from onion was optimized using orthogonal array design.Results indicated that technological parameters of microwave-assisted extraction affected total flavonoids yield in the following order of microwave extraction time microwave power ethanol concentration material/liquid ratio.A maximum total flavonoids yield of 1.81% was obtained through the optimal procedure based on 60 s extraction using 70% ethanol as the extraction solvent with a material/liquid ratio of 1:60 in 960 W microwave field.
