Isoflavones are polyphenolic compounds found mainly in legumes the benefits of which have been widely studied and attributed in particular to their phytoestrogenic activity The aim of this study was to evaluate the quail-quantitative composition of food supplements based on soy isoflavones (Glycine max L) and red clover (Trifolium pratense) Six commercial food supplements (five soy-based and one red clover-based) were analyzed by HPLC/DAD/MS Genistein, daidzein, glycitein, biochanin A and formononetin derivatives (glycosides and aclglycosides) were identified in the analyzed samples Also the antiradical activities (towards the DPPH center dot radical) and Fe(2+) chelating abilities were compared

Abstract
Isoflavones are polyphenolic compounds found mainly in legumes the benefits of which have been widely studied and attributed in particular to their phytoestrogenic activity The aim of this study was to evaluate the quail-quantitative composition of food supplements based on soy isoflavones (Glycine max L) and red clover (Trifolium pratense) Six commercial food supplements (five soy-based and one red clover-based) were analyzed by HPLC/DAD/MS Genistein, daidzein, glycitein, biochanin A and formononetin derivatives (glycosides and aclglycosides) were identified in the analyzed samples Also the antiradical activities (towards the DPPH center dot radical) and Fe(2+) chelating abilities were compared
