Study on Anti-thrombosis Effect of Volatile Oil of Acorus Tatarinowii Schott and ?-asarone / 中药新药与临床药理

ABSTRACT

Objective To Study on anti-thrombosis effect of volatile oil of Acorus Tatarinowii Schott(AST) and ?-asarone.Methods Thrombosis test,blood hyperviscocity test,blood clottingtest,and in vitro fibrinolytic test were carried out to investigate the effects of volatile oil of AST and ?-asarone on the following indexesweight of thrombus,prothrombin time(PT),activated part prothrombin time(APTT),hemorheology,clotting time,the weight of plasma fibrin clot.Results Volatile oil of AST and ?-asarone can lower the weight of venout thrombosis in rats,and prolong PT and APTT of blood plasma in rats.They can improve hemorheology in the hyperviscocity rats,especially reduce viscosity of whole blood and blood plasma obviously.They can prolong the clotting time in mice obviously;and decrease the weight of plasma fibrin clot.Conclusion Volatile oil of SCP and ?-asarone has anti-thrombosis anticoagulationand fibrinolyitc effect,and its mechanism may be related to the prolongation of PT and APTT,improving blood viscosity.
