| Abstract: |
| The experiment was conducted to optimize the ultrasound-assisted extraction conditions of total flavonoids in Mangifera indica L. leaves collected from Maoming City，Guangdong Province. The extraction temperature，ultrasound power and extraction time were chosen as causal factors to optimize the yield of total flavonoids by response surface method（RSM）. The optimal extraction conditions were as follows: extraction time 48 min，extraction temperature 65℃ and ultrasound power 90 W. Under the optimized conditions，the extraction rate of flavonoids was 5.26%. These results indicated that the optimized conditions obtained from RSM were stable and practicable. |
