Fibrinolytic, thrombin inhibitory, anti-oxidative and anti-inflammatory activities of Pleurotus ferulea

아위버섯을 혈관계질환 예방과 치료를 위한 기능성 식품 개발에 이용하기 위한 기초 자료를 얻기 위해 아위버섯 물추출물과 유기용매 분획물의 혈전용해활성과 트롬빈 저해활성, 항산화활성 및 항염증활성을 확인하였다. 에틸아세테이트 분획물은 1.33 plasmin unit의 높은 혈전용해 활성과, 94.45%의 높은 트롬빈 저해활성을 나타냈으며, 물 추출물은 37.01%의 항산화활성을 나타냈으며, 클로로포름 분획물은 98.13%의 가장 높은 항염증활성을 나타냈다. 실험 결과로부터 아위버섯의 에틸아세테이트 분획물은 높은 혈전용해활성, 트롬빈 저해활성 그리고 클로로포름 분획물은 높은 항염증활성을 나타내 심혈관계 질환 관련 치료나 예방을 위한 기능성식품 개발에 이용 가능할 것으로 기대된다. Our study investigated the fibrinolytic, thrombin inhibitory, anti-oxidative and anti-inflammatory activities of the water extract and solvent fractions isolated from Pleurotus ferulea. Fibrinolytic activity was investigated using the fibrin plate method. Thrombin inhibitory activity was used to analyze thrombin inhibitor assay. The DPPH assay was used to estimate anti-oxidative activity. Inhibition of NO production was measured for anti-inflammatory activity in LPS-activated murine RAW 264.7 macrophage cells. An MTS assay was used to evaluate the effects of the water extract and solvent fractions isolated from Pleurotus ferulea on cell viability. Our results showed the fibrinolytic activity to be strong in the ethyl acetate fraction at 1.33 plasmin units. The ethyl acetate fraction also showed high thrombin inhibitory activity at 94.45%. The anti-oxidative activity of the water extract was 37.01% and the anti-inflammatory activity of the chloroform fraction was 98.13%. These findings suggest that Pleurotus ferulea's extract and fractions could be applicable in the development of functional foods for the treatment and prevention of cardiovascular diseases.
