Anti-thrombotic effect of rutin isolated from Dendropanax morbifera Leveille

Dendropanax morbifera H. Lev. is well known in Korean traditional medicine for improvement of blood circulation. In this study, rutin, a bioflavonoid having anti-thrombotic and anticoagulant activities was isolated from a traditional medicinal plant, D. morbifera H. Lev. The chemical characteristics of rutin was studied to be quercetin 3-O-α-l-rhamnopyranosyl-(1-6)-β-d-glucopyranoside using high performance liquid chromatography mass spectrometry (HPLC-MS), proton nuclear magnetic resonance (1H NMR) and carbon-13 nuclear magnetic resonance (13C NMR). Turbidity and fibrin clotting studies revealed that rutin reduces fibrin clot in concentration dependent manner. Rutin was found to prolong activated partial thromboplastin time (aPTT), prothrombin time (PT) and closure time (CT). Furthermore, it decreased the activity of pro-coagulant protein, thrombin. In vivo study showed that rutin exerted a significant protective effect against collagen and epinephrine (or thrombin) induced acute thromboembolism in mice. These results suggest that rutin has a potent to be an anti-thrombotic agent for cardiovascular diseases. •Isolation of rutin from Dendropanax morbifera Leveille with anti-thrombotic activity.•Rutin was found to inhibit fibrin clotting and thrombin activity effectively.•Rutin inhibited thrombosis and acute thromboembolism.•Rutin exhibited anticoagulant and anti-platelet properties.
