摘要/Abstract

摘要： 测定了7个甜橙品种果汁中主要活性成分,包括VC、多酚、总类胡萝卜素及类柠檬苦素的含量,VC的含量介于390.6～478.6mg/L之间,多酚类介于573.1～655.0mg/L,总类胡萝卜素介于5.47～7.25mg/L,类柠檬苦素介于0.10～0.17mg/L。用ABTS/K2S2O8体系测定的反映总抗氧化能力的TEAC值介于4.79～6.09之间,血橙最高,锦橙最低。TEAC值与VC的相关度达到显著水平(r=0.868,p=0.011),与多酚类达到极显著水平(r=0.909,p=0.003),而与总类胡萝卜素则无显著相关关系(p>0.1),表明多酚类物质可能是甜橙品种中主导的抗氧化活性成分。

关键词: 甜橙, 活性成分, TEAC值

Abstract: The contents of antioxidant components in seven kinds of orange juices were assayed with the contont of VC ranges from 390.6 to 478.6 mg/L,of polyphenols from 573.1 to 655.0 mg/L of carotenoids from 5.47 to 7.25 mg/L and of limonoids from 0.10 to 0.17 mg/L.The TEAC values determined by ABTS/K2S2O8 system are from 4.79 to 6.09,with blood orange the highest and Jincheng the lowest.The relationship between TEAC values and the content of VC shows remarkable level(r = 0.868,p=0.011),and that between TEAC and polyphenols is significant(r=0.909,p=0.003),while there is no obvious correlationship between the TEAC and carotenoids(p>0.1).It was concluded that the polyphenols are probably the dominant antioxidant component in these seven kinds of oranges.
