Abstract

The ability to determine the total reductant capacity (i.e. the total amount of electron-donating antioxidants) in dietary foodstuffs would be useful, because foods contain a number of different components with reducing activity. We assessed reducing activity in a variety of edible plants, including various fruits, vegetables, roots, and tubers. The reductive effect was assessed by measuring the ability of each sample to inhibit the oxidation of oxymyoglobin (MbO2) to metmyoglobin (metMb). We found that several types of plant, such as Chinese cabbage, lemon, paprika, and radish, show marked inhibitory effects on MbO2 oxidation. Using the MbO2 assay, it was determined that L-ascorbic acid (AsA) was the main reductive substance in these active plants. However, the majority of the plants tested, including herbs that are regarded as being abundant in antioxidants, were found to promote MbO 2 oxidation. The results of the present study may be useful in the identification of beneficial dietary foodstuffs.
