ABSTRACT

<p><b>OBJECTIVE</b>To study the hypolipidemic active compounds from Crataegus pinnatifida and mechanism of action of those.</p><p><b>METHOD</b>Guided by the inhibitory activity to HMG-CoA reductase, the active compounds were separated and purified with macroporous resin and silica gel.</p><p><b>RESULT</b>Four active compounds were obtained, which were quercetin, hyperoside, rutin and chlorogenic acid, the sum of their inhibitory rate was 50.01%, and the total inhibitory rate of the mixture of four active compounds matched was 79.48%.</p><p><b>CONCLUSION</b>Quercetin and hyperoside were the principle active components inhibiting HMG-CoA reductase in Hawthorn fruit, and there were synergistic action among them.</p>
