Abstract

Physiological functionalities of various extracts from Danmemil and legumes were determined and its optimal extraction conditions were also investigated. Angiotensin I-converting enzyme (ACE) inhibitory activity and tyrosinase inhibitory activity of Danmemil were higher in water extracts (53%, 58%) than those of ethanol extracts. However, its electron-donating ability was the highest in ethanol extracts (72%). ACE inhibitory activity and electron-donating ability of Black bean No. 1 and Taekwangkong(one of bean) were higher in water extracts than those of ethanol extracts, whereas SOD-like activity was the highest in ethanol extracts. ACE inhibitor and tyrosinase inhibitor of Danmemil were maximally extracted when it were treated with 20 times of distilled water at 35$^{\circ}C$ for 24 h and 36 h, respectively. Its electron donating compound was maximally extracted by treatment of 50$^{\circ}C$ for 18 h. ACE inhibitor of Black bean No. 1 was extracted maximally when it was treated with distilled water (1 :20) at 20$^{\circ}C$ for 24 h, whereas the other functional compounds were maximally extracted at 20$^{\circ}C$ for 18 h.

단메밀과 콩 등으로부터 생리기능성 물질을 추출하여 건강식품을 개발하고자 먼저 물과 에탄올을 사용하여 extracts를 추출한 후 엔지오텐신 전환효소 (ACE) 저해활성과 항산화활성 및 SOD-유사활성 등을 측정하였다. 단메밀의 ACE저해 활성과 tyrosinase 저해 활성은 물 추출물에서 각각 53%와 58%로 에탄을 추출물보다 더 높았고 전자공여능은 에탄을 추출물에서 제일 높은 72%를 보였다. 검정종 1호와 태광콩의 ACE 저해 활성과 전자공여능은 물 추출물에서 높았으나 SOD-유사활성은 에탄을 추출물에서 가장 높았다. 단메밀 중의 ACE 저해물질과 tyrosinase 저해 물질들은 20배의 증류수로 35$^{\circ}C$에서 각각 24시간, 36시간 처리했을 때 가장 많이 추출되었고 전자공여능을 나타내는 항산화물질은 5$0^{\circ}C$에서 18시간 처리했을 때 가장 많이 추출되었다. 또한 검정콩 1호의 ACE 저해물질은 2$0^{\circ}C$, 24시간에서 가장 많이 추출되었으나 그 밖의 기능성 물질들은 2$0^{\circ}C$에서 18시간 추출하였을 때 가장 많이 추출되었다.
