솔잎과 녹차의 열수와 에탄올 추출물을 이용하여 free radical 반응 및 지방산화에 미치는 영향과 아질산염 소거작용을 검토하였다. 각종 항산화제와 항산화력 비교에서 추출물 농도별 지방산화 억제능력은 0.1%보다는 0.3%가 낮은 TBARS값을 나타내었고, iron sources에 대한 binding 능력은 열수추출물이 우수하였다. Deoxyribose상에서의 hydroxyl radical 포집능력은 솔잎과 녹차 에탄올추출물이 대조구 보다 낮은 TBARS값은 나타내었다. 추출물의 iron 함량은 솔잎 에탄올 추출물이 가장 높은 함량을 나타내었으며, ascorbic acid 함량은 녹차의 열수와 에탄올 추출물에서 높은 값을 나타내었다. 전자공여능은 열수추출보다는 에탄올 추출물이 높은 활성을 나타내었다. 또한 솔잎과 녹차추출물은 각종 항산화제에 비하여 높은 전자공여능을 나타내었다. 아질산염 소거작용은 pH의 감소에 따라 높게 나타났으며, 0.3%의 솔잎과 녹차 추출물은 pH 1.2와 pH 3.0에서 95% 이상의 소거능을 나타내었으며, ascorbic acid 자체보다도 높은 소거능을 나타내었다. 이상의 결과로 보아 솔잎과 녹차추출물은 각종 육제품 제조시 첨가물로서 산화방지 효과 및 아질산염 소거제로서의 사용을 시사하는 것이다.

The natural sources extracted from green tea and pine needle were utilized to investigate the effects of extracts on free radical reaction, lipid oxidation and nitrite scavenging ability. The degree of lipid oxidation is very sensitive to kinds of oil emulsion reacted with iron sources and oxygen species. The antioxidants of extracts from green tea and pine needle were different depending on concentration of extracts, which were a lower TBARS value in 0.3% extracts concentration, compared to 0.1% extracts concentration. And also, the binding ability on iron sources was superior in hot water extracts, but oxygen scavenging ability was the lowest TBARS values in ethanol extracts. The hydroxyl radical scavenging ability of green tea and pine needle extracts had a little low TBARS value in 0.1% and 0.3% extracts concentration in deoxyribose. The ethanol extracts of pine needle were higher than those of hot water extracts on the basis of F2^2+ ion content. The ascorbic acid content of green tea showed 14.3 ㎎/100 g in hot water extracts and 16.7 ㎎/100 g in ethanol extracts. Electron donating ability of extracts showed difference depending on extracts concentration, which were higher in ethanol extracts than those of hot water extracts. The nitrite scavenging effects were tended to be different depending on pH value, however they were decreased overall as pH value was increased. Especially, the nitrite scavenging ability of 0.3% extracts from green tea and pine needle were the most effective in pH 1.2 and pH 3.0, which were showed 95% nitrite scavenging ability.
