Abstract

Samples (10 mg/mL) of wild Grifola frondosa aqueous extract and solvent fractions were examined for fibrinolytic, thrombin inhibitory, acetylcholinesterase inhibitory, and antioxidative activities to determine the biological activities. The fibrinolytic activity of the aqueous extract and solvent fractions was 0.93 and 0.73 plasmin units/mL, respectively. The thrombin inhibitory activity of the butanol extract was 79.60%. The chloroform fraction had high acetylcholinesterase inhibitory activity (85.88%). The aqueous extract had low antioxidative activity (39.81%). The aqueous fraction hydrolyzed Bβ subunits of human fibrinogen but did not show any reactivity for the γ form of the human fibrinogen. The findings indicate the potential of wild Grifola frondosa for the development of drugs and bio-functional foods to prevent cardiovascular diseases.

야생 잎새버섯 추출물을 이용하여 심혈관계 질환과 관련된 기능성 식품 개발을 위한 기초자료를 얻기 위해 준비한 물 추출물과 유기용매 분획물의 혈전용해활성과 트롬빈저해활성, acetylcholinesterase 저해활성, 항산화활성을 확인하였다. 10 mg/mL의 농도에서 물 추출물과 물 분획물은 각각 0.93 plasmin unit와 0.73 plasmin unit의 높은 혈전용해활성을 나타냈으며, 부탄올 분획물은 79.60%의 트롬빈저해활성을 나타냈다. 클로로포름 분획물은 85.88%의 높은 acetylcholinesterase 저해활성을 나타냈고, 물 추출물의 항산화 활성은 39.81%로 비교적 낮게 나타냈다. 부분 정제된 효소를 포함하고 있는 물 분획물은 섬유소원의 Bβ chain를 모두 분해시켰지만, Aα chain은 느리게 분해시키고 γ chain 과는 반응하지 않았다. 실험 결과로부터 야생 잎새버섯 추출물은 높은 혈전용해활성과, 트롬빈저해활성, acetylcholinesterase 저해활성을 나타내 심혈관계 질환 예방을 위한 제약과 기능성식품 개발에 이용 가능할 것으로 기대된다.
