Abstract: Among the multiple components of propolis, flavonoids contribute greatly to the antioxidant activities of propolis. Flavonoids mainly exist in the form of sugar-conjugated derivatives. Quercetin glycosides represent the predominant flavonoid fraction in propolis. In this… read more here.

Abstract: The regiospecific synthesis of three quercetin O-β-glucosides of N-acetylglucosamine has been achieved in good yield. Selective di-and tri-O-benzylation of quercetin followed by O-glycosylation with 2-acetamido-3,4,6-tri-O-acetyl-2-deoxy-α-D-glucopyranosyl chloride under phase-transfer catalysis conditions yielded, after deacetylation and debenzylation,… read more here.
