桃花中绿原酸抗氧化活性的研究
Antioxidant Activity of Chlorogenic Acid Extracted from Peach Blossom
摘要
Abstract
Taking Peach blossom as test material,antioxidant activity of chlorgenic acid extracted from peach blossom was measured by D-deoxyribose-iron system method along with 2,2-diphenyl-1-picrylhydrazyl pyrogallol autoxi-dation method,while vitamin C and chlorgenic acid were used as reference substance and reduction ability of the extract was measured by using K3[Fe(CN)6]. The results showed that peach blossom extract had strong reducibility,and its an-tioxidant activity was closely related to chlorgenic acid content. The extract had higher anti-hydroxyl and anti-DPPHo activ-ity but lower anti-superoxide anion activity than vitamin C. Its reducibility with concentration of 200 μg·mL －1for hydroxyl was as high as 66.42%,and antioxidant activity was 95.78% and 82.12% for superoxide anion and DPPHo,respec-tively. This study showed that the main extract of peach blossom was chlorgenic acid and its concentration largely determine reductive and antioxidant activities for the extract.关键词
