Abstract: Investigation of thrombolytic activityof crude extracts of Camellia sinensis (Green tea) using in-vitrothrombolytic model which is very simple, rapid and easy to do method. Both aqueous crude and methanolic extracts were studied however; the results of methanolic extract were more promising which exhibited maximum 95. 24% clot lysis as compared to aqueous one i.e. 90.34% at 800 μg/ml concentration in 72 hrs of incubation. Various concentrations of leaf extract i.e. 200μg/ml, 400μg/ml, 600ug/ml and 800μg/ml were tested at different time intervals including; 24hrs, 48hrs and 72hrs duration of incubation at 370 C for observing maximum clot lysis. The result indicated that concentrations of leaf extract enhanced the percentage of clot lysis in dose dependent manner. On the other hand, Streptokinase SK, a reference standard and water were used as a positive and negative control showed clot lysis maximum 96.63% and 41.32% in 72 hrs of incubation respectively. From results, it can be concluded that if further studies reveals the exact molecule from green tea diverse composition, an effective thromolytic candidate can be achieved for the improvement of the patients suffering from Atherothrombotic diseases.
