혹진주벼 미강으로부터 생리기능성 물질을 추출하여 이들을 이용한 생리기능성 제품을 개발하기 위하여 먼저 흑진주벼 미강에 함유되어있는 유용물질들을 추출한 후 이들의 생리기능성을 측정하였고 미강 중에 많이 함유되어있는 ACE저해활성물질과 혈전용해활성물질, 전자공여물질과 tyrosinase 저해물질들의 추출최적조건을 검토하였다. ACE 저해활성과 혈전용해활성 및 tyrosinase 저해활성은 물 추출액에서 높았고 전자공여능은 hexane 추출액에서 높았

Physiological functionalities in various extracts of Heugjinju rice bran were determined and its optimal extraction condition were also investigated Angiotensin-converting enzyme(ACE) inhibitory activity, fibrinolytic activity and tyrosinase inhibitory activity were higher in water extracts than those of 80% ethanol and methanol, hexane. Electron donating abilities were 97.8% in hexane extract and 83% in water extracts. ACE inhibitor was maximally extracted from Heugjinju rice bran when it was treated with 20 times of distilled water for 12 h at 20 . Fibrinolytic compound was also maximally extracted by treatment of 10 times of distilled water for 18 h at 20 . Electron donating compound and tyrosinase inhibitor were maximally extracted by treatment of 20 times of hexane and 10 times of distilled water at 20 for 18 h, respectively
