This study was performed to investigate the biological activities of Hericium erinaceus fruiting body, including antioxidative, fibrinolytic, thrombin inhibitory and α-glucosidase inhibitory activities. The water extract of H. erinaceus was fractionated into hexane, chloroform, ethyl acetate, butanol and water fractions, and each of these fractions was individually assayed. The water extract showed high antioxidative activity at 87.78%. The water fraction showed the highest extraction yield at 35.68% (w/w). In the fraction activity tests, butanol and water fractions showed strong antioxidative activities at 87.91% and 92.27%, respectively. Assays for fibrinolytic activity indicated that only the ethyl acetate fraction has significant efficacy at 2.96 plasmin units/mL. The 10-fold dilution of hexane fraction showed high thrombin inhibitory activity, and α-glucosidase inhibitory activity at 77.67% and 90.53%, respectively. In conclusion, solvent fractions of H. erinaceus can be used as materials for the development of biofunctional foods to prevent cardiovascular diseases.
