Objective:To optimize extraction technology of garlic flavonoids according the amount of flavonoids as index. Method:Influences of microwave pretreatment time,ethanol concentration and the ratio of solid to liquid on yield of garlic flavonoids were inspected by orthogonal experiment design,then optimum technology conditions were obtained. Result:The optimum process conditions were as follows:microwave power was set at medium fire,the time of microwave pretreatment was 150 s,the ratio of solid to liquid was 1∶40 and ethanol concentration was 80%. Conclusion:Microwave-assisted ex-traction of garlic flavonoids has many advantages,such as high extraction rate,fast speed,less solvent consumption,etc.
