경상도 전통마른오징어 식해를 제조하여 $5^{circ}C$에서 보관하면서 GC와 GC-MS를 이용하여 향기성분의 원인 물질을 분석, 동정하였다. 식해에서 동정된 물질 중에서 ${alpha}-zingibirene$이 19.73 mg/kg으로 전체상대 농도에서 가장 높았으며 (Z)-Di-2-propenyl disulfide, ${alpha}-curcumene$, methyl alkyl disulfide, $(E-E)-{alpha}-farnesene$, pentanol, z-citral, $3-ethyl-1,2-dithi-5-ene-{eta}-elemene$, acetic acid 및 ${eta}-phelland$ rene의 함량 순으로 동정되어 이러한 성분들이 식해의 주요성분으로 나타났다. 식해의 향기성분은 hydrocarbone류가 49종, 알데히드류가 15종, 알콜류가 33 종, 케톤류 및 에스테류 11 종을 포함하여 총 162 종을 동정하였다. 식해의 메탄올 추출물을 용매 분획하여 얻은 각 분획물의 전자공여능을 측정한 결과 $200;{mu}m$ DPPH radical을 50% 환원시키는데 필요한 $SC_{50}$ 값이 헥산과 물층에서는 효과가 나타나지 않았으며, ethylacetate 층은 $310.64;{mu}g/mL$, butanol 층은 $1096.49;{mu}g/mL$으로 나타났다. 혈압상승 억제효과를 살펴본 결과 헥산과 물 분획물에서는 전혀 효과가 없었으며 ethylacetate층에서는 $IC_{50}$이 1.623 mg/mL, butanol 층에서는 1.303 mg/mL의 저해효과를 나타내었으며, xanthine oxidase에 대한 $IC_{50}$은 ethyl acetate 층은 3.591 mg/mL, butanol 층은 2.083 mg/mL로 나타났다.
The volatile compounds of traditional Kyungsando squid sikhe were identified by GC-MS. The amount of ${alpha}-zingibirene$ among identified volatile compounds was 19.73 mg/kg. The major volatile compounds of sikhe were (Z)-Di-2-propenyl disulfide, ${alpha}-curcumene$, methyl allyl disulfide, (E, E)-a-farnesene, pentanol, z-citral, 3-ethyl-1,2-dithi-5-ene-${eta}-elemene$, ${eta}-elemene$, acetic acid, and ${eta}-phellandrene$. The volatile compounds of sikhe were compose of 49 including hydrocarbone groups, 15 aldehydes groups, 33 alcohol groups kinds, 11 ketone and ester groups. The fraction obtained from sikhe were tested for electron donating ability, angiotensin converting enzyme inhibitory activity and xanthine oxidase inhibitory activity. There were no electron donating abilities$(SC_{50})$ in hexane and water soluble fractions. On the other hand, the angiotensin converting enzyme abilities of ethylacetate and butanol soluble fractions were $310.64;{mu}g/mL$ and $1096.49;{mu}g/mL$, respectively. Angiotensin converting enzyme inhibitory activities$(IC_{50})$ of ethylacetate butanol soluble fractions were 1.623 mg/mL and 1.303 mg/mL, respectively. Xanthine oxidase inhibitory activities$(IC_{50})$ of ethylacetate fraction and butanol soluble fractions were 3.591 mg/mL and 2.083 mg/mL, respectively.
