Abstract
Glycosides, acylated glycosides, and sulfates of quercetin (= 3,3 ' ,4 ' ,5 ,7-pentahydroxyflavone; 1), which is, together with its derivatives, among the most common polyphenols found in plants and in the human diet, were pre pared and quantitatively investigated for their ability to bind metal ions (Al-III, Fe-II, Fe-III), enhance and vary natural colours (anthocyanin copi gmentation), and trap potentially damaging radicals (antioxidant activity).
