ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect and mechanism of Scutellaria Baicalensis Stem-leaf Total Flavonoid (SSTF) on lipid metabolism in hyperlipidemic rat.</p><p><b>METHOD</b>On the basis of establishing hyperlipidemia rat model, blood lipids, lipid metabolic enzyme, antioxidative capacity were investigated after 30 days feeding of fatty emulsion.</p><p><b>RESULT</b>SSTF significantly reduced the serum TC, TG, LDL-C, ApoB concentration and increased HDL-C and ApoAI levels, improved the activity of lecithin cholesterol acyltransferase (LCAT). SSTF was shown to decreased MDA content in both serum and liver, increased serum SOD activity.</p><p><b>CONCLUSION</b>SSTF could remarkably modulate the lipid metabolic disorder in hyperlipidemic rats, and has a certain regulating function on lipoprotein, inferring that it could reduce the occuring of atherosclerosis. The mechanism of regulating lipid metabolism might be related with the increasing activity of LCAT and antioxidative capacity.</p>
