朝鲜蓟叶提取物的体外抗氧化作用
In Vitro Study on Antioxidant Activity of Artichoke Leaf Extract
【摘要】 对朝鲜蓟叶提取物(ALE)进行体外抗氧化实验,评价其抗氧化功能。采用4种不同的体外抗氧化评价体系对ALE进行抗氧化功能的评价,结果以IC50来表示。ALE在4种系统中表现出不同的抗氧化能力。其中以NH2OH-Xan-XOD系统的IC50值最低,为16.5μg/mL,二酪氨酸/酪氨酸系统的IC50值最高,为310μg/mL。ALE具有抗氧化作用,且存在剂量依赖效应。
【Abstract】 To evaluate the anti-oxidative function of artichoke leaf extract(ALE) by anti-oxidation experiments in vitro.Four different antioxidant evaluation systems in vitro were assessed for anti-oxidation function of ALE with the results expressed as IC50.ALE in the four kinds of systems showed different antioxidant capacity.Among them,NH2OH-Xan-XOD system showed the lowest IC50 value of 16.5 μg/mL,while dityrosine/tyrosine system,showed the highest IC50 value of 310 μg/mL.ALE had anti-oxidant activity with dose-dependent effect.
