This study was to investigate the hypolipidemic and anti-inflammatory properties of Abacopterin A (APA), a flavonoid compound isolated from Abacopteris penangiana (Hook.) Ching. Male C57BL/6J mice were divided randomly and equally into five groups: the normal control group (N), the model group (M), the positive control group (P), the high and low doses of APA treated groups (H and L). All the animals except that in N group were fed with high-fat diet for 8 weeks. In the last 4 weeks, the mice in P, H and L groups were orally administered with simvastatin (at the dose of 20 mg/kg/day) and APA (at the dose of 40 or 20 mg/kg/day), respectively. Then the lipid profiles and related biochemical criterions of the studied mice were determined. The effects of high-fat diet on activating nuclear transcription factor-kappa B (NF kappa B) expression, elevating inflammatory factors tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) levels, and increasing triacylglycerol (TG) and total cholesterol (TC) levels were abolished on daily supplementation with APA. APA also enhanced lipoprotein lipase (LPL) and hepatic lipase (HL) activities. These results suggested that APA had hypolipidemic and anti-inflammatory properties through inhibiting NF kappa B expression, and reducing inflammatory response. (C) 2011 Elsevier Ltd.
