Nonetheless, the major question that needs to be addressed is whether TPC and antioxidant potential of food plants are predictive of the ability to inhibit protein glycation. It is known that Flavonoids and other constituents in plants inhibit protein glycation. However, the top dietary sources of these compounds have not been screened systematically for potential effects on glycation. The results should be considered as representative, in as much as the quantities of phenolics observed depend upon the solvent used, as well as cultivars and conditions for plant growing, harvesting, drying, and storage.
