This articles studied the extraction of flavonoids with the technology of microwave. The effects of average microwave output power, concentrations, diffent solvents and microwave irradiation time on the extraction yield were investigated. The parameters of extraction process were optimized through orthogonal test and average microwave output power was 200W, alcohol concentration was 50%, solid/liquid rate 1:30 and microwave irradiation time was 10min. The orthogonal test result indicated that, the primary f...
