Antihaemolytic, Antihaemorrhagic and Antifibrinolytic Effects of Fractions of Buchholzia coriacea Seeds on Naja nigricollis Crude Venom

Bulchhozia coriacea (Capparaceae) seeds are used in managing snake bite in Western Nigeria were investigated against Naja nigricollis (Spitting cobra) venom-induced hemolytic, hemorrhagic and fibrinolytic effects. This study was aimed at determining the antihaemolytic, antihaemorrhagic as well as antifibrinolytic effects of B. coriacea on N. nigricollis crude venom. Microwave-assisted extraction with hexane, chloroform, ethyl acetate, and methanol was carried out. Naja nigricollis venom-induced erythrocyte lysis (100 %) was significantly reduced to 18% by the chloroform fraction at 0.625 mg/mL. At the concentration of 0.625 mg/mL, the hexane, chloroform, ethyl acetate and methanol fractions administered in combination with the venom reduced percentage hemorrhagic activity to 23%, 17%, 49%, and 87%, respectively. In conclusion, Bulchhozia coriacea seed fractions exhibited significant antihaemolytic, antihaemorrhagic and antifibrinolytic activities against N. nigricollis crude venom and may beneficial as a pre-treatment the while victim is transferred to a healthcare facility to receive the definite treatment to ensure speedy recovery.
