摘要

Recent studies on food function show that foods and their components exhibit anti-inflammatory and anti-allergic activities. We have investigated the suppressive effect of flavonoids on lipopolysaccharide(LPS)-induced prostaglandin(PG) production on rat peritoneal macrophage and tumor necrosis factor (TNF)-α-stimulated E-selectin expression on human umbilical vein endothelial cells (HUVECs) carrying out a comparative examination of the flavonoids. A comparison of the subclasses showed that flavone and flavanone on prostaglandin production, flavone and flavonol on E-selectin expression were relatively more effective than other subclasses. From the viewpoint of the structure, the C2-C3 double bond of C ring and the 4-oxo functional group are essential for their inhibition activities. The glycosylated derivatives of the various flavonoids exhibit less inhibitory activities than their corresponding aglycones.
