Determination of Prooxidant Activities of Several Fruit Juices and Herbs

Under oxidative stress conditions, which are defined as the deterioration of antioxidant and prooxidant balance in organism favor prooxidants, ROS species that trigger formation various diseases occur. The fact these harmful cause damage to biological macromolecules is expressed activity. In this study, Cu(II)‒catalyzed activities pomegranate, apricot, peach, pear juices extracts mint, white tea, rosehip were measured by using gold nanoclusters synthesized via chicken egg proteins. Fluorometric spectrophotometric nanocluster biosensors carbonyl assay used. fruit used directly diluting with pure water. Herbal plant samples extracted an ultrasonic water bath, filtered through microfilters, stored refrigerator. Total herbal plants calculated terms mM epicatechin equivalent, results obtained applying all methods compared each other. It has been found applied can be accurately determine total activity many food products.
