The mature fruit of Sorbus commixta is known as magaja in Korea and is consumed in the form of tea and wine. In addition, it has been used to treat hypertension and articular neuralgia in folk medicine. In this study, the ethanol extract of magaja and its subsequent organic solvent fractions were prepared, and their in vitro anti-coagulation, and platelet aggregation inhibitory activities were evaluated. Among the fractions, the ethylacetate fraction demonstrated significant inhibition against thrombin, prothrombin, blood coagulation factors and platelet aggregation, without hemolysis activity up to 0.5 mg/ml. Our results suggest that the ethylacetate fraction of magaja has the potential to be used as a new anti-coagulation agent.
