摘要
目的:研究壮药红鱼眼黄酮类化合物的提取工艺及其抗氧化活性。方法:用乙醇回流提取法通过正交设计试验确定黄酮提取工艺的最佳条件,用氧化法测定其清除超氧自由基和DPPH·自由基的能力。结果:红鱼眼黄酮提取的最佳条件为:8倍量60%乙醇提取3次,每次1 h。所得黄酮在一定浓度范围内具有较强的清除自由基和抗氧化能力。结论:优选的提取工艺效率高,所制备的黄酮有较强的清除超氧自由基和DPPH·自由基活性,具有很好的抗自氧化效果,是一种较好的天然抗氧化剂。
To study the extraction technology and antioxidant activity of flavonoids in Phyllanthus reticulaliis.Method： The optimal extraction technology of flavonoids was screened by orthogonal design,and the clearance of superoxide radical and DPPH·were detected by oxidation method.Result;The optimal extraction conditions were as follows;adding 8-fold of 60%ethanol and extracting 3 times with 60 min for each.The obtained flavonoids showed significant radical scavenging and antioxidant activity within the experimental concentration range.Conclusion：The optimal extraction technology exhibits higher extraction efficiency,and the flavonoids show promising radical scavenging and antioxidant activity.The obtained flavonoids can be used as promising natural antioxidants.
