人类饮食在保护免受氧化应激方面具有重要作用。这种健康保护因素部分归因于具有抗氧化能力的化合物，水果和蔬菜是膳食抗氧化剂的主要来源。安达卢西亚的园艺生产包括各种各样的水果和蔬菜，不仅在西班牙，但也在其他欧盟countries.本研究的目的是评估的抗氧化能力的44种水果和蔬菜在安达卢西亚种植的食用部分，通常由西班牙和其他欧洲消费者消费。根据每种作物的收获期在不同时间收集样品，进行三种体外测定：TEAC（trolox当量抗氧化能力）、FRAP（铁离子还原抗氧化能力）和ORAC（氧自由基吸收能力）。Trolox/100 g）、“Fino”柠檬（11.560-14.340 mmol eq. FeSO 4/100 g）和红洋葱（2.921-13.830 mmol eq. Trolox/100 g）。结果还表明，“Vivaldi”马铃薯是所有评估方法中抗氧化能力最低的样品（0.035-0.590 mmol eq. Trolox/100 g，在TEAC中，0.200-0.399 mmol eq. FeSO 4/100 g FRAP溶液和0.238-0.286 mmol eq.总之，这项研究提供了一个全面的比较，在安达卢西亚种植的水果和蔬菜，可以全年获得的不同品种之间的抗氧化能力。这些信息表明，分析的安达卢西亚品种是抗氧化剂的良好来源。(C)2014爱思唯尔有限公司版权所有。
Human diet has an important role in protection against oxidative stress. This health-protecting factor has been partly attributed to the compounds with antioxidant capacity, fruits and vegetables being major sources of dietary antioxidants. Horticultural production in Andalusia includes a large variety of fruits and vegetables which are available not only in Spain but also in other European Union countries.The aim of the present study was to evaluate the antioxidant capacity of the edible portion of 44 fruits and vegetables grown in Andalusia and commonly consumed by both Spanish and other European consumers. The samples, collected at different times according to the harvesting period of each crop, were submitted to three in vitro assays: TEAC (trolox equivalent antioxidant capacity), FRAP (ferric ion reducing antioxidant power), and ORAC (oxygen radical absorbance capacity).The samples showing the highest antioxidant capacity were red 'California' pepper (4.550-13.810 mmol eq. Trolox/100 g), 'Fino' lemon (11.560-14.340 mmol eq. FeSO4/100 g), and red onion (2.921-13.830 mmol eq. Trolox/100 g) in the TEAC, FRAP, and ORAC assays, respectively. The results also showed that 'Vivaldi' potato was the sample with the lowest antioxidant capacity in all the methods assessed (0.035-0.590 mmol eq. Trolox/100 g in TEAC, 0.200-0.399 mmol eq. FeSO4/100 g in FRAP and 0.238-0.286 mmol eq. Trolox/100 g in ORAC assay).In conclusion, this study provides a comprehensive comparison of the antioxidant capacity among different cultivars of fruits and vegetables grown in Andalusia that can be acquired year round. This information reveals that the Andalusian cultivars analyzed are good sources of antioxidants. (C) 2014 Elsevier Ltd. All rights reserved.
