野菊花乙醚提取物的理化性质及抗氧化能力

研究野菊花乙醚提取物的基本理化性质及其抗氧化特性。结果表明:野菊花乙醚提取物中类胡萝卜素含量为(165.51±1.42)mg/g,β-胡萝卜素含量为(2537.96±11.57)μg/g;抗氧化实验显示提取物均能够有效阻止花生油、大豆油、葵花籽油、玉米油的脂质快速氧化,且具有剂量效应关系。野菊花乙醚提取物是一种潜在的油脂氧化保护剂,具备一定的抗氧化能力。

Physicochemical Characterization and Antioxidant Activity of Ether Extract from Flos chrysanthemi indici

Physicochemical proprieties and antioxidant activity of ether extract from Flos chrysanthemi indici were investigated in this study.The yield of dried ether extract from crude materials(dry weight) was 2.15%.The content of carotenoids in dried extract was(165.51 ± 1.42) mg/g.The ether extract was added to four kinds of edible oil including peanut oil,soybean oil,sunflower oil and corn oil to evaluate its antioxidant activity.Our results indicated that the ether extract could effectively inhibit lipid oxidation and displayed a potential antioxidant activity in a dose-dependent manner.Therefore,this ether extract may be considered as a potential antioxidant agent.
