Abstract

The objective of this study was to identify and characterize fibrinolytic compound from Cornus officinalis. Cornus officinalis. Hot water extract was fractionated into hexane, chloroform, ethyl acetate, butanol, and water fractions. Assays for fibrinolytic activity indicated that only the ethyl acetate fraction had significant efficacy at 1.36 plasmin units/mL. Isolation of fibrinolytic compound was carried out on Amberlite IRA-400, Sephadex LH-20 and active charcoal column chromatography. HPLC analysis of the purified fibrinolytic compound showed retention time (RT) same as authentic malic acid. LC / MS / MS in negative mode showed the same peak at m/z 133, confirming that the purified compound was malic acid with a molecular weight 134 Da. The compound showed fibrinolytic activity of 0.69 plasmin units/mL, 14.62% of thrombin inhibitory activity, 6.42% of antioxidative activity, and 17.28% of α-glucosidase inhibitory activity. The purified compound hydrolyzed γ subunits of human fibrinogen. In conclusion, malic acid isolated from Cornus officinalis might have potential to be developed as ingredient for biofunctional foods to prevent cardiovascular diseases.

산수유 열수추출물의 혈전용해활성을 탐색하고, 유기용매로 분획화한 에틸아세테이트(ethyl acetate) 분획물에서 1.36 plasmin units/mL의 강한 혈전용해활성을 확인하였다. Amberlite IRA-400, Sephadex LH-20 column, active charcoal column과 재결정으로 정제한 혈전용해화합물을 HPLC로 분석 비교한 결과, 표준물질인 malic acid와 같은 retention time (RT)을 나타내고, LC/MS/MS 분석의 Negative mode 측정 시 m/z 133에서 같은 peak를 나타내어 정제한 화합물이 분자량 134 Da인 malic acid 임을 확인하였다. 정제한 화합물은 0.69 plasmin units/mL의 혈전용해활성을 보이고, 14.62%의 트롬빈 저해활성을 나타냈으며, 6.42%의 항산화 효과와 17.28%의 항당뇨 효과를 나타냈다. 분리한 화합물은 섬유소원의 Aα chain, Bβ chain과 반응하지 않았지만 γ chain을 분해하는 것으로 나타났다. 위 연구 결과를 바탕으로 산수유에서 분리한 혈전용해화합물은 혈관계 질환의 치료제 개발과 기능성 식품 개발을 위한 우수한 소재로 이용 가능할 것으로 예상된다.
