Abstract

Ehwa nuruk (EN), a traditional Korean alcoholic rice beverage, is manufactured from pulverized wet rice and the needles of pine trees. In this study, the ethanol extract of EN and its subsequent organic solvent fractions were prepared, and their in-vitro anti-thrombosis activity evaluated. In an anti-coagulation assay, only the ethylacetate (EA) fraction of the ethanol extract showed significant extensions of thrombin time, prothrombin time and activated partial thromboplastin time. In a platelet aggregation assay, the water residue of the ethanol extract exhibited aggregation inhibitory activity. Our results suggest that the EA fraction has potential as a new anticoagulation agent and EN could be used as a novel resource for anti-thrombosis agents. This report provides the first evidence of the anti-thrombosis activity of EN.

이화누룩은 증자하지 않은 쌀을 물에 불린 후 분쇄하고, 이를 솔잎으로 띄워 발효시킨 한국 전통누룩이다. 이화누룩의 기능성을 평가하기 위해 이화누룩의 에탄올 추출물과 이의 순차적 유기용매 분획물을 조제하고 항혈전 활성을 평가하였다. 그 결과, ethylacetate 분획물은 강력한 thrombin time, prothrombin time, aPTT 연장효과를 나타내었으며, 유기용매 분획후의 물 잔류물에서는 강력한 혈소판 응집저해능이 확인되었다. 본 연구결과는 이화누룩의 ethylacetate 분획이 신규의 항혈전제로 사용 가능함을 나타내며, 이는 이화누룩의 항혈전 활성에 대한 최초의 보고이다.
