Oxidative stress due to reactive oxygen species (ROS) can cause oxidative damage to cells. Mitochondria are especially important in the oxidative stress as ROS have been found to be constantly generated as an endogen threat. Mitochondrial defense depends mainly on superoxide dismutase whereas microsomal defense depends on catalase, which is an enzyme abundant in microsomes. Seven weeks-aged female Sprague-Dawley rats were divided into four groups and fed high fat diets for 44 days. Also fermented Rhynchosia nulubilis was administered orally for 44 days at 7.5 ml/kg of body weight of rats. The antioxidative activities of fermented Rhynchosia nulubilis were measured by the superoxide dismutase, catalase, malondialdehyde levels in liver homogenate. The levels of malondialdehyde in FRN-treated groups were lower than those in obese groups. Superoxide dismutase and catalase levels were significantly increased. These results demonstrated that fermented Rhynchosia nulubilis had the inhibitive effects of oxidative stress in obese rats, suggesting that fermented Rhynchosia nulubilis would be used as an ingredient of the useful functional products.

Results and Discussion DPPH radical 소거효과측정발효서목태의 DPPH radical 소거효과결과는 Fig. 2와같다. 발효서목태엑기스의 DPPH radical 소거효과는각각 ± 0.63%, ± 2.47%, 4.93 ± 0.63%, 3.56 ± 0.17% 이며, 발효서목태음료에서는각각 6.37 ± 0.54%, 3.77 ± 0.73%, 2.87 ± 0.15%, 1.80 ± 1.20% 로발효서목태엑기스가발효서목태음료보다 DPPH radical 소거효과가높았으며, 농도의존적으로감소하였다. 홍등 14) 의연구에따르면, 대두와서목태열수추출물의 DPPH에대한전자공여능은농도가증가함에따라증가하였고, 서목태추출물은 73.05%, 대두추출물은 57.70% 로본연구에서도사용된서목태가대두보다높은전자공여능을나타냈다. Dordevic 등 8) 의연구에서메밀, 보리, 밀및호밀의 DPPH radical 소거능을연구한결과, 메밀이가장높은소거능을보였으며고농도로갈수록높은소거능을나타냈다. 또한 L. rhamnosus와 S. cerevisiae로각각발효를했을때, 비슷한소거능을보였지만비발효일때보다는높은소거능을나타냈다. 이에따라본연구에서는발효한서목태를사용하였다. 총폴리페놀함량측정발효서목태의총폴리페놀함량을측정하는결과는 Fig. 3과같다. 발효서목태엑기스의총폴리페놀함량은각각 ± 0.73 µg/ml, ± 0.57 µg/ml, ± 0.05 µg/ ml, ± 0.37 µg/ml이며, 발효서목태음료에서는각각 ± 0.60 µg/ml, ± 0.41 µg/ml, ± 0.08 µg/ml, ± 0.06 µg/ml로발효서목태엑기스가발효서목태음료보다폴리페놀의함량이더높았으며, 농도가높을수록폴리페놀함량이높았다. 박등 24) 의연구에의하면, 된장의총폴리페놀함량이 4.17 ± 0.11 mm gallic acid equivalent로가장높게나타났으며, 그외대두식품의경우메주 (2.310 ± 0.09 mm gallic acid equivalent), 청국장 (1.785 ± 0.07 mm gallic acid equivalent) 및콩 (0.585 ± 0.03 mm gallic acid equivalent) 순으로폴리페놀함량이높게나타났다. Arellano-gonzalez 등 2) 의연구에따르면, 발효를하지않은커피는 335 ± 71 w/(g/kg) 이고, 발효를한커피는 ± 30.1 w/(g/kg) 로써발효를한커피가더높은함량을나타냈다. 이에따라본연구에서는발효한서목태를사용하였다. 간에서의 CAT 활성변화 CAT 는 H 2 를무독성의 H 2 O로환원시키거나 methanol, ethanol, formic acid 및 phenol과같은 hydrogen donor의산화에관여하는효소로서지방산화에의해생성된유리기를제거하는것으로알려져있으며활성산소종을소거시키는작용을한다 15,23).

CAT 는정상군이 0.57 ± 0.06 nmol/mg protein, 대조군은 0.38 ± 0.01 nmol/mg protein, 발효서목태엑기스섭취군은 0.57 ± 0.08 nmol/mg protein, 발효서목태음료섭취군은 0.56 ± 0.02 nmol/mg protein로, 발효서목태엑기스섭취군과발효서목태음료섭취군이대조군에비해 94.7~100% 증가하여정상군으로의회복을나타냈다. Carillon 등 5) 의연구에서는정상군과비만을유도시킨대조군의 CAT 활성보다 SODB( 멜론 ) 을섭취한군이현저하게 CAT 활성이증가되었으며내인성발현또한 50% 증가한것으로나타났다. 이를통해 CAT 가증가된것은활성산소를제거하여생체내대사과정에서생성된과산화물로부터생체조직을보호하여손상된간조직의기능을회복시킨것이기때문에발효서목태가 CAT 활성에유의적인효과가있는것으로사료된다. 간에서의 SOD 활성변화체내에축적된과량의활성산소는암을발생시키거나노화를촉진하는등유해한영향을미친다. 이러한활성산소는과식, 과도한스트레스및흡연, 지나친운동으로야기되는과호흡등에의해그양이증가하는데이러한활성산소를체내에서가장먼저분해시키는역할을하는효소가바로 SOD이다. SOD라는효소는 25세까지는체내에서자연적으로생성되므로별문제가없으나, 25세이후부터는 SOD 발생량이줄어들어서신체는점점노화되어간다, SOD는생체내의항산화방어기구중에서효소적방어계의하나로 superoxide radical을환원시켜 H 2 로전환시킴으로써산소독으로부터생체를보호한다 10). 비만을유도한 rat의간균질액에서 SOD의활성변화 는 Fig. 5와같다. 정상군이 ± 0.58 nmol/mg protein 로나타났고대조군은 ± 0.58 nmol/mg protein, 발효서목태엑기스섭취군은 ± 7.26 nmol/mg protein, 발효서목태음료섭취군은 ± 9.40 nmol/mg protein로발효서목태섭취군의 SOD 수치가대조군에비해 55.4~ 86.8% 증가하여정상군으로의회복을보였다. 류등 12) 의연구에따르면대조군의 SOD 활성이 9.84 ± 2.50 U/mg protein이고, 발효대두를 200 mg/kg 첨가군에서 ± 3.06 U/mg protein으로 40% 증가했다. 본연구에서의비만유도흰쥐의 SOD 활성이더높았으므로대두보다서목태가간에서의 SOD 활성에상승효과가있을것으로예측된다. 이를통해발효서목태가간에서의 SOD 활성증가에도움을주는것으로사료된다. 간에서의 MDA 변화과산화지질은 oxygen radicals에의해불포화지방산에서일어나는연쇄반응으로 oxygen radicals의직접적인작용보다는철이온존재하에 superoxide와 H 2 의상호작용에의해형성되는 OH 0 에의해간접적으로일어나며, 이의주된손상장소가 DNA나세포막이다 11). MDA는발암의가능성이있고, 돌연변이를일으킬수있으며, 고도로반응성이높은 free radical들은여러가지세포의중요한구성성분들, 즉지방세포막, DNA, 단백질등을변형시키는것으로알려져있다 12). 비만을유도한 rat의간균질액에서 MDA의활성변화는 Fig. 6과같다. 정상군이 ± 1.13 nmol/mg protein 로나타났고대조군은 ± 1.23 nmol/mg protein, 발효서목태엑기스섭취군은 ± 1.12 nmol/mg protein, 발효서목태음료섭취군은 ± 1.14 nmol/mg protein로

All the values were expressed as means ± S.D. (n = 6), ***means each group was significantly different (P < 0.001) for the value of CON in student s test. 발효서목태섭취군의 MDA 수치가대조군에비해 88.6~ 90.1% 감소하여정상군에가까운수치를보였다. 성등 28) 의연구에서는 MDA량이물추출물투여군은 2.28%, 알코올추출물및지용성추출물투여군은 18.53%, 30.1% 씩감소함을보였으며, 총사포닌투여군은 13.25% 로물추출물을제외한모든추출물에서유의성있게감소함을보였다. 본연구에서의비만유도흰쥐의 MDA량이더감소하였으므로사포닌보다서목태가지질과산화억제에더효과가있을것으로예측된다. 이를통해발효서목태가지질과산화를억제하는것으로사료된다. 국문요약 본연구에서는유도비만쥐에서발효서목태의항산화효과를연구하기위하여체중 175 g의 SD계암컷흰쥐 24 마리를대상으로정상군, 고지방식이군, 발효서목태엑기스급여군, 발효서목태음료급여군으로분류하여 54 일간사육하였다. in vitro 항산화활성에서는발효서목태엑기스가높은활성및함량을나타냈다. in vivo 항산화활성에서는발효서목태섭취군이고지방식이대조군에비해 CAT, SOD 활성은높은활성을보였으며, MDA량은감소현상을보였다. 이와같은결과를통해발효서목태가항산화효소의증가로활성산소의제거능을향상시킬뿐만아니라, 생체내대사과정에서생성된과산화물로부터생체조직을보호하여손상된간조직의기능을회복시킨것으로사료된다.
