| 摘 要： | 目的:研究木蝴蝶总黄酮的抗氧化活性。方法:采用二苯代苦味酰基苯肼(DPPH)法、水杨酸法和邻苯三酚自氧化法来考察其抗氧化活性,并与Vc做比较。结果:在试验浓度内,木蝴蝶总黄酮对二苯代苦味酰基苯肼自由基(DPPH.)、羟自由基(.OH)和超氧阴离子自由基(O2-.)均有较好的清除作用,其EC50分别为19.73,231.70,318.93 mg·L-1,在9.52～57.12 mg·L-1,其对DPPH.的清除率高于VC。结论:木蝴蝶总黄酮有良好的抗氧化活性,具有进一步开发利用的价值。

| Abstract: | 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. |
