Objective: To study the antioxidant activity of total flavonoids from Oroxylum indicum. Method: The antioxidant activity of the total flavonoids from O. indicum was determined by DPPH
salicylic acid and pyrogallol auto-oxidation. Result: Compared with Vc
the total flavonoids from O. indicum had better scavenging effect on DPPH·
·OH
O2-·in the determination of the concentration range
the EC50 was 19.73
231.70
318.93 mg·L-1 respectively; and the scavenging effect on DPPH·was better than Vc in the concentration range of 9.52-57.12 mg·L-1. Conclusion: The total flavonoids from O. indicum had better antioxidant activities
so it would be valuable to be further developed and used.
