黄山杜鹃茎总生物碱的体外抗氧化活性研究

Study on Antioxidant Activity of Total Alkaloids from the Stem of Rhododendron anhwiense Wils.in Vitro

以总还原力和DPPH自由基、ABTS自由基、超氧阴离子自由基清除作用为指标评价黄山杜鹃茎生物碱的抗氧化活性,各抗氧化活性指标的IC50值分别为500.01、43.59、32.45、62.05μL。黄山杜鹃茎生物碱具有一定抗氧化活性,且活性与样品量呈量效关系。

The antioxidant activity of total alkaloids from the stem of Rhododendron anhwiense Wils.in vitro was evaluated by total reducing power and scavenging capacity against DPPH.and ABTS.,and O2-.with IC50 value of 500.01、43.59、32.45、62.05μL.Therefore,total alkaloids from the stem of Rhododendron anhwiense Wils.had some antioxidant activity in a concentration-dependent fashion.
