Abstract
Using microwave assisted extraction of flavonoids in hawthorn leaves,and optimize the extraction process. Choose microwave radiation time, microwave power and solid- liquid ratio three factors that influencing the extraction effect single factor experiment,and the influencing factors of the extraction yield of total flavonoids in the use of the Design- Expert 8 for response surface analysis test. The results show that the microwave assisted extraction of flavonoids in hawthorn leaves the best process conditions are as follow: microwave irradiation time 120 s, microwave power 400 W, solid- liquid ratio 33 ∶1, under these conditions the yield of flavonoids in hawthorn leaves is 7.49 mg/g.
