Abstract

Microwave assisted extraction of total flavonoids from hawthorne was optimized by an orthogonal test.The results showed that the extraction rate of flavonoids is mostly influenced by ratio of solid-liquid,followed by ethanol concentration,microwave extracting time and microwave power.The optimum process parameters are microwave power 400 W,extracting time 120 s,ethanol concentration 60 % and ratio of solid-liquid 1∶40(g/mL).Under these conditions,the extraction yield is up to 3.19 %.
