对食用植物油测砷湿法消化的探讨
Measurement of antioxidant activity using biologically relevant assays is important in the screening
of fruits for potential health benefits. The cellular antioxidant activity (CAA) assay quantifies antioxidant
activity in cell culture and was developed to meet the need for a more biologically representative
method than the popular chemistry antioxidant capacity measures. The objective of the study was to
determine the cellular antioxidant activity, total phenolic contents, and oxygen radical absorbance
capacity (ORAC) values of 25 fruits commonly consumed in the United States. Pomegranate and
berries (wild blueberry, blackberry, raspberry, and blueberry) had the highest CAA values, whereas
banana and melons had the lowest. Apples were found to be the largest contributors of fruit phenolics
to the American diet, and apple and strawberries were the biggest suppliers of cellular antioxidant
activity. Increasing fruit consumption is a logical strategy to increase antioxidant intake and decrease
oxidative stress and may lead to reduced risk of cancer.
