| 摘 要： | 为了解密蒙花总黄酮清除自由基的能力,利用紫外-可见分光光度法对比研究了密蒙花总黄酮对1,1-二苯基-2-苦基肼自由基(DPPH.)、羟基自由基(.OH)、2,2-联氮-二(3-乙基-苯并噻唑-6-磺酸)二铵盐自由基(ABTS+.)和超氧阴离子自由基(O2-.)的清除作用。结果表明,密蒙花总黄酮能有效清除DPPH.、.OH、ABTS+.和O2-.。当密蒙花总黄酮质量浓度达到4.8 mg/L时,对DPPH.、.OH、ABTS+.和O2-.清除率分别可达77.88%、35.42%、85.08%和56.91%。

| Abstract: | In order to know the free radical scavenging effects of flavonoids from Buddleja officinalis Maxim,UV-Vis spectrum was used to study the scavenging effects of flavonoids from B.officinalis Maxim on 1,1-diphenyl-2-picrylhydrazyl(DPPH ·),hydroxyl(· OH),ABTS + ·,and superoxide(O-2 ·) free radicals.The results showed that flavonoids of B.officinalis Maxim could be well used in scavenging DPPH ·,· OH,ABTS + · and O-2 ·.When the concentration of the flavonoids concentration of B.officinalis Maxim reached 4.8 mg/L,the scavenging rates could reach 77.88%,35.42%,85.08% and 56.91%,respectively. |
