RESUMO
Objective To investigate the anticoagulant activities of phlorotannins STP-1 and STP-2 from Sargassum thunbeergii Kuntze.Methods Coagulation time(CT)and bleeding time(BT)of mice were determined by in-vivo experiment to test the effect of phlorotannins by capillary method and cutting tail method respectively.Furthermore,activated partial thromboplastin time(APTT),prothrombin time(PT)and thrombin time(TT)were measured to evaluate the in-vitro anticoagulant activity of phlorotannins on New Zealand rabbits.Results Phlorotannins STP-1 had a significant effect on the prolongation of CT,BT,APTT,PT and TT,especially at the dosage of 1.0 mg/mL.Conclusion Phlorotannins STP-1 has both in-vivo and in-vitro anticoagulant activity.
