| 摘 要： | Quercetin (3, 3’, 4’, 5, 7-pentahydroxyflavone) is one of the most common flavonols present in nature. The complexation of Al(III) by various flavonoids has been suggested to reduce the overload of aluminum in the diet, a metal which has been implicated…

| Abstract: | Complex formation between aluminium and quercetin(Q) in methanol was investigated by means of 27Al solid-state,13C and 1H NMR and MS(ESI),UV and IR spectra. Formation of the 1:2 complex was favored in methanol relative to all other solvent and the predominant species observed of Al(III) has a 1:2 stoichiometry. The fine structure of 1:2 aluminum complex of quercetin was that the aluminum central atom chelated with two quercetin molecules and two methoxyl groups between two five membered rings,its coordination is six,the chelated site was 3-hydroxy-4-carbonyl. |
