Abstract/OtherAbstract:
The ethanol extract of Pithecellobium clypearia Benth (PCE) was characterized to be rich in polyphenols by HPLC analysis, and investigated for its anti-inflammatory and anti-allergic activities. In our assay, PCE showed anti-inflammatory activity in both acute and auto-immune inflammation animal models. Administration of PCE can effectively inhibit the croton oil-induced ear edema and capillary permeability, the carrageenin-induced paw edema, and the liver injury caused by propionibacterium acnes plus lipopolysaccharide. PCE was also found to possess anti-allergic activity in inhibiting the DNFB-induced delayed hypersensitivity reaction. Meanwhile, seven main components (1-7) from PCE were studied for their effect on histamine release stimulated by compound 48/80 from rat peritoneal mast cells in vitro. Compound 2 ((-)-epigallocatechin-7-gallate), 3 ((-)-5, 7, 3', 4', 5'-pentahydroxyflavan), and 5 ((-)-tetra hydroxyflavan-7-gallate) showed significant inhibition effect on histamine release.
