Optimization of ultrasound-assisted extraction of flavonoids from Gnaphlium affine by Box-Benhnken Design |
| |
| Abstract: | A four-factor-five-level Box-Benhnken Design was applied to optimize the parameters of ultrasound-assisted extraction of flavonoids from Gnaphlium affine D. Don. Basing on single factor experiments, extraction temperature, ethanol content, ultrasonic power and solid-liquid ratio were investigated. Results showed that the optimal ultrasound-assisted conditions of flavonoids were as follows:extraction temperature, 35 ℃;ethanol content, 73%;ultrasound power, 350 W;solid-to-liquid ratio, 1 ∶ 35. Under this condition and to be extracted for 50 minutes, the maximum extraction rate of flavonoid was 15.25%. |
