본 연구에서는 양파가공부산물인 양파껍질을 이용하여 기능성 식품소재로 개발하고자 양파껍질추출물을 제조하였으며 양파껍질추출물에 대한 생리적 기능성과 같은 품질 특성을 조사하였다. 양파껍질추출물에서는 K가 13,767.56~15,506.78 ppm으로 가장 많은 함량을 차지하였고 Na이 8,602.44~9,796.00 ppm, Ca은 4,255.78~4,903.33 ppm으로 세 번째로 많은 함량을 차지하였다. 그리고 Mg, P, Fe은 각각 1,433.11~1,561.22 ppm, 1,212.44~1,428.89 ppm, 760.67~858.89 ppm의 함량을 차지하였고 Zn은 34.11~66.89 ppm으로 미량 검출되었다. Total phenol 함량은 598.57~626.73 mg/g, total flavonoid 함량은 211.73~238.52 mg/g 범위로 quercetin 함량은 93.67~107.29 mg/g의 범위로 나타났다. 양파껍질추출물의 DPPH radical 소거활성은 100 ppm에서 16.45~17.92%, 200 ppm은 29.96~35.41%, 1,000 ppm은 81.05~84.60%의 소거활성을 보였고, SOD 유사활성은 10,000 ppm에서 31.92~39.29%, 20,000 ppm에서 85.85~91.58%의 활성을 나타내었다. 혈전용해능은 20,000 ppm 농도에서는 plasmin에 비해 약 3배 높은 활성을 가졌다. 따라서 양파껍질 추출물은 항산화력 및 항혈전효과능을 가진 기능성소재로서의 활용 가능성을 보였다.

For the development of functional food and cosmetics using hot water extract of Muraenesox cinereus's skin, contents of vitamin, amino acid and element, and antioxidant activity were investigated. The results are shown as follows: among vitamins, A(0.21mg/100 g), C (78.12mg/100 g), $D_3$ (0.03 mg/100 g), E (1.97 mg/100 g) and Niacin (2.53mg/100 g) were detected, respectively.Mineral contents were an order of K > P > Na > Mg > Ca > Fe and Zn. Contents of total amino acids were an order of Pro > Gly > Arg > Glu > Phe > Ala. Especially, the sum of total amino acids was 27.17 mg/100 mL, which was about 4.0 fold higher than that of free amino acid. DPPH radical scavenging activity of hot water extract of M. cinereus's skin at 25 mg/mL was 63.5% and did not increase at above 50 mg/mL. Activities of antioxidant enzymes in the liver of ethanol-treated rats using hot water extract of M. cinereus's skin were investigated. Compared to control group, activities of ADH and GSH-px were decreased. In the case of CAT and SOD activity, they were increased. These results showed that the hot water extract of M. cinereus's skin can be applied to raw macterial for functional food and cosmetics.
