초록

산마늘 잎 에탄올추출물을 Steptococcus thermophilus 를 이용하여 발효시킨 후 항산화활성 및 세포독성을 검정한 결과, 총 폴리페놀 함량은 발효 전에는 2.63 mg/g, 발효 후에는 1.65 mg/g이었으며 발효 후 함량이 감소하였고, 플라보노이드 함량은 발효 전에는 57.77 mg/g, 발효 후에는 62.27 mg/g으로 발효 후에 증가하였다. 전자공여능은 발효 전에는 82.29%, 발효 후에는 81.40%로 vitamin C (97.71%) 보다 낮았으나 우수한 활성을 나타냈으며, 아질산염소거능은 발효전 후 추출물 모두 pH 2.5에서는 BHT 보다는 낮지만 활성이 우수하였고, pH 4.2에서는 발효하지 않았을 때 BHT보다 더 좋은 활성을 나타냈으며. SOD 유사활성능은 15% 정도로 낮은 효과를 나타냈다. NO 생성능은 발효 전에 오히려 더 많은 NO를 생성하였고 발효 후에는 생성이 억제되었다. 산마늘 추출물이 LPO 생성에 미치는 영향은 H2O2 처리군에 비하여 발효 여부와 관련 없이 산마늘 추출물처리에 따라 농도가 증가할수록 MDA 함량이 감소하여 LPO 생성을 억제하는 것으로 나타났으며, 섬유아세포의 생존율은 산마늘 추출물 처리 농도의 증가에 따라 약간 감소하는 경향이나 대조구와 차이가 거의 없었다.

This study was conducted to investigate the antioxidative activity and cytotoxicity of fermented Allium victorialis extract. The results were as follows; The total polyphenol content of A. victorialis extract was 2.63 mg/g, and that of fermented A. victorialis extract was 1.65 mg/g which decreased a little by fermentation. The total flavonoid content of A. victorialis extract was 57.77 mg/g, and that of fermented A. victorialis extract was 62.27 mg/g, and this could increase a little from fermentation. Electron donating ability of A. victorialis extract was lower than vitamin C(97.71%), but before fermentation it was 82.29% and after fermentation it became 82.40%. Nitrite scavenging ability of A. victorialis extract before and after fermentation showed lower numerical value than that of butylated hydroxytoluene(BHT) at pH 2.5 but that of A. victorialis extract expressed higher than that of BHT. Superoxide dismutase-like activity showed relatively low level, 15%. Nitrite production increased by A. victorialis extract but was inhibited after fermentation. Methyl diamphetamine (MDA) content was inhibited with increased concentration of A. victorialis extract compared with H2O2 treatment but there was not any difference before and after fermentation. Therefore, production of lipid peroxide(LPO) was inhibited by A. victorialis extract. Cell viability of fibroblast cell was tend to slightly decrease with increased concentration of A. victorialis extract, but not different with control.
