Flavone was extracted from orange peel using the ultrasonic-assisted semi-bionic approach. The response surface methodology analysis showed that total extraction of flavone was 6 . 23 mg/g under the condition of 1. 3,7. 6 and 8. 4 pH value of three times respectively,32 min extraction time,53 ℃ extrac-tion temperature,350 W ultrasonic power and 21 kHz ultrasonic frequency. The antioxidant testing re-vealed that the ultrasonic-assisted semi-bionic approach could improve the inoxidizability. As the concen-tration of orange peel flavoe was about 9 mg/L, the scavenging ratio of · DPPH, · OH, and O2-· reached about 37. 6%,52. 1% and 46. 1%,respectively,which had improved 11. 6%,12. 7% and 7. 6%comparing with the solvent extraction method.
