Anticoagulant and Thrombolytic Activities of Leaf Extract of Mangifera Indica in Smokers
Main Article Content
Abstract
This study investigated the anticoagulant and thrombolytic activities of Mangifera indica in smokers. Methods: The thrombolytic and anticoagulant (in vitro and in vivo) activities, phytochemical screening and high performance liquid chromatography of aqueous-methanolic (70:30) leaf extract of M. indica have been investigated. Results: For in vitro experiment M. indica displayed a noteworthy (p<0.05) increment in prothrombin time, clotting time and activated partial thromboplastin time while in vivo experiment noteworthy (p<0.05) increase in clotting time, bleeding time, activated partial thromboplastin time and prothrombin time in a dose-dependent manner in rabbits after one week of treatment while heparin being taken as a positive and distilled water being taken as negative control. For in vitro experiment, aqueous-methanolic extract in a dose-dependent manner displayed noteworthy (p<0.05) clot lysis while streptokinase being taken as a positive and distilled water being taken as negative control. Conclusion: HPLC showed the presence of mangiferin, quercetin and isoquercetin which down regulate the activity of factor Xa as well as act on antithrombin and thrombin respectively, in coagulation cascade.
