dc.description.abstractFood and feed of plant origin containing phytochemicals of great antioxidant potential are called nowadays “functional”, which means that they beside nutritive traits, feature also some medicinal properties. Plant phenolics show useful characteristics in human and animal metabolism, such as antiinflamatory and even anticarcinogenic. They posses antibacterial, antimutagenic and vasodilatory activities, as well. Acting as natural antioxidants they lower the risk of atherosclerosis and cardiac illness. Thus, soybean based feed enriched with polyphenols may be classified as functional feed in animal diet. Content of total polyphenols, tannins, flavonoids and anthocyanins were evaluated in the seeds of seven soybean varieties of different seed color. One yellow seed cultivar represented a reference genotype. Isoflavone (phytoestrogen) content and composition was determined using HPLC analysis on an Agilent model 1100, equipped with diode array detector (DAD). Aglycons were quantified from three five- 0.9998) obtained using the corresponding standards (daidzein, glycitein and genistein). In addition, antioxidant activity of seed extracts was evaluated by the 2,2-diphenyl-1- picrylhydrazyl (DPPH) free radical scavenging activity assay. A positive linear correlation between antioxidant activity and contents of total polyphenols and anthocyanins was established. The highest antioxidant activity was observed in the extracts of black and brown varieties, which also showed high levels of all polyphenol classes examined. Yellow seed had the highest total isoflavone content (3.62 mg/g of dry material). The highest concentration of total daidzein was determined in black seeds (>2.0 mg/g d.m.), and the highest total glycitein and genistein contents occurred in the yellow cultivar (0.53 and 1.49 mg/g d.m., respectively). Varieties of black and brown seeds could be of special interest due to large content of polyphenols (4.94-6.22 mg/g d.m.), especially from the class of anthocyanins. Obtained data should enable the selection of genotypes rich in natural antioxidants that could further be processed into functional feed in animal diet.sr
