Composition containing flavonol glycosides of green tea for inhibiting protein glycation reaction

摘要

A composition comprising the green tea extract or flavonol glycosides isolated therefrom is provided to inhibit production of intermediates or AGEs(advanced glycation end-products) by protein glycation reaction, so that the composition is useful for improving skin wrinkles. A composition for improving skin wrinkles comprises 0.0001-10 wt.% of flavonol glycosides isolated from the green tea extract as an effective ingredient, wherein the flavonol glycosides are flavonol galactose glycosides or quercetin glycosides and inhibit protein glycation reaction; the composition is a cosmetic, a pharmaceutical external skin or an edible composition; and the daily dosage of flavonol glycosides is 0.001-2000 mg/kg.
