The Antioxidant and Nitrite Scavenging Activity of Wild Grape(Vitis coignetiea) Wine

머루와인의 항산화성 및 아질산염 소거능

Total anthocyanin and color intensity contents of wild grape wine were $4.3{\pm}0.3%$ and $10.2{\pm}0.8%$, respectively. The contents of total phenols and flavonoid in wild grape wine were $18.8{\pm}3.9$ mg/100 g, $0.5{\pm}0.2$ mg/100 g, respectively. Total mineral content in wild grape wine was $22.6{\pm}0.2$ mg/100 g and the 10 minerals of the potassium content ($5.3{\pm}0.2$ mg/100 g) was the highest. Electron donating abilities of wild grape juice at concentration of 1,000 ${\mu}L/mL$ were $90.4{\pm}1.8%$. Reducing power of wild grape wine at concentration of 1,000 ${\mu}L/mL$ were 0.932. The electron donating abilities and reducing power were increased significantly by increased the sample concentration in the reaction mixture. The nitrite scavenging ability was dependent on pH of reaction mixture and sample concentration. The nitrite scavenging ability of wild grape win was $76.3{\pm}1.3%$ at concentration of 1,000 ${\mu}L/mL$ under pH 1.2.

머루와인의 pH는 $3.7{\pm}0.1$, 총 안토시아닌 함량은 $4.3{\pm}0.3$, 색도는 $10.2{\pm}0.8$이었으며, 총 페놀과 플라보노이드의 함량은 각각 $18.8{\pm}3.9$ mg/100 g, $0.5{\pm}0.2$ mg/100 g이었다. 무기질은 총 10종이 검출되었으며, 특히 K의 함량이 $5.3{\pm}0.2$ mg/100 g으로 가장 높은 함량을 보였다. 전자공여능을 측정한 결과, 1,000 ${\mu}L/mL$의 농도에서 $90.4{\pm}1.8%$로 가장 활성이 뛰어났으며, 환원력을 측정한 결과, 농도가 1,000 ${\mu}L/mL$일 때 환원력은 0.932를 나타내었다. 그리고 아질산염에 대한 소거능을 측정한 결과, pH 1.2의 조건일 때 1,000 ${\mu}L/mL$의 농도에서 $76.3{\pm}1.3%$로 가장 뛰어난 소거능을 보였다. 머루와인의 농도가 증가함에 따라 실험 결과는 유의적으로 증가하는 경향을 보였다.
