The antioxidative and antiaging effects of 262, 622 and 442 mixed ratios were evaluated by the determination of superoxide radical scavenging activities, hydroxy radical scavenging activities, linoleic acid inhibition activtiy, elastin synthesis activity, and cell viability of B16F10. The material of 442 ratio showed the higher effects than those of 262 and 622 ratios, and presented the higher effect than the separate material of red ginseng in the antioxidative and antiaging activities. Therefore, this study suggested that the material of 442 ratio in the production of red gineng- containing cosmetics could be preferred as a useful cosmetic ingredient for antioxidation and antiaging.

Superoxide Radical 소거효과 2',7'-dichlorodihydrofluorescein diacetate (DCFDA) 1 mm 50 µl와 esterase (600 unit/ml) 50 µl를혼합한뒤 37 o C에서 20분간반응시켜 2',7'-dichlorodihydrofluorescein (DCFH) solution을만든후 DCF측정법을사용하여서평가하였다 15). 96 well plate에농도별각시료 10 µl를넣고 50 mm 칼륨인산완충용액 130 µl를넣은뒤 20 mm menadion 10 µl 와칼륨인산완충용액으로 100배희석한 DCFH solution 50 µl를넣고 5분간섞어준다. Elisa (Microtiter plate reader, Molecular Devices Co., Sunnyvale, CA., USA) 로 485/530 nm에서 fluorescence를 5분간격으로 30분간측정하였다. Hydroxy Radical 소거효과 DCFDA (1 mm) 와 esterase (600 unit/ml) 를혼합한뒤 37 o C에서 20분간반응시켜 DCFH solution을만들어 DCF 측정법을이용하여실시하였다 16). 96 well plate에농도별각시료를넣고 10 mm FeSO 4 와 1.35 mm H 2 O 2 를섞은혼합액을넣어준다. 100배희석한 DCFH solution를넣고 5분간섞어준다. Elisa (Microtiter plate reader, Molecular Devices Co., Sunnyvale, CA., USA) 로 485/530 nm 에서 Fluorescence를 10분간격으로 40분간측정하였다. 대두시료제조 20 g의대두에 Bacillus subtilis를 600 nm 흡광도가 1.0 일때 1% 를접종하여 40 o C에서 36시간동안고체발효하였다. 대두발효시료에 80% 에탄올을 4시간동안침지후상등액을채취하여 40 o C에서농축시킨대두발효추출물을동결건조하여사용하였다. 미강시료제조 20 g의미강을멸균수 200 ml을혼합하여 Bacillus subtilis 를 600 nm 흡광도가 1.0일때 1% 를접종하여 40 o C에서 36 시간동안고체발효하였다. 미강발효시료에 80% 에탄올 지질과산화억제효과자동산화가잘되는물질인리놀산을이용하여자동산화를억제하는효과를실험한것으로 10 mm 리놀산용액과시료를농도별로첨가한후 4 o C, 24시간보관후지질과산화정도를 thyocyanate법에의하여실시하였다 17). 상기의혼합액에 75% 에탄올을첨가하여교반한후 30% NH 4 SCNsolution과 20 mm FeCl 2 을첨가하여 3분간방치한후발색시켜 Elisa (Microtiter plate reader, Molecular Devices Co., Sunnyvale, CA., USA) 로 500 nm에서흡광도를측정한다.

MTT를이용한세포독성측정 MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) 는 Sigma Chemical Co. (St. Louis, MI, USA) 제품을사용하였다. 실험에사용한 melanoma cell 인 B16F10 은한국세포주은행에서분양받았으며 10% 의 fetal bovine serum (FBS, Bio whittaker) 와 1% 의 penicillin (Bio whittaker) 이첨가된 dulbecco's modified eagle medium (DMEM, Bio whittaker) 으로 37 o C, 5% CO 2 조건에서 48시간배양한후 96-well plate에세포현탁액을 180 µl 씩분주하고, phosphatebuffer of saline (PBS, Bio whittaker) 로 sample을희석한후농도별로 20 µl 씩첨가하였다. 37 o C, 5% CO 2 조건에서 48시간동안추가배양한후배양액을제거하고 MTT (5 mg/ ml in PBS) 용액을 100 µl 씩가하고 37 o C, 5% CO 2 에서 4시간동안추가배양하였다. 이후 DMSO 100 µl를넣고 37 o C, 5% CO 2 에서 10~15분동안반응시킨후발색정도를 Elisa (Microtiter plate reader, Molecular Devices Co., Sunnyvale, CA., USA) 를이용하여 540 nm에서흡광도를측정한다. 통계처리본실험에대한모든실험결과는평균치와표준편차로나타내었고, 통계적유의성은 SPSS 12.0 (SPSS Inc., Chicago, IL, USA) 를이용한 one-way ANOVA 로검정하였으며, 사후검증으로 Duncan's post-hoc test를실시하였고유의성은 p < 0.05로하였다. 결과및고찰 Superoxide Radical 소거효과활성산소는체내생물학적반응에서만들어지며정상적인경우 superoxide dismutase (SOD) 에의해과산화수소로전환되지만, 과잉생산이될경우체내에서독성을나타내게되어여러가지질환을발생시키기도한다 18,19,20). Superoxide radical 소거실험결과는 Table 1과같다. 442 > 622 > 262 순으로 84%, 83%, 60% 의소거활성을보였으며, 농도의존적인 superoxide radical 소거활성을보였다. 가장높은활성을보인 442는표준물질로사용된 vitamin C와유사한활성을보였으며, 이는본연구실에서선행되어진개별연구결과인발효된홍삼 70% 12), 발효된미강 89% 13), 발효된대두 89% 14) 와비교했을때 superoxide radical 결과에서 84% 의소거활성을보여미강과대두와는비슷하지만홍삼과비교하였을때혼합비율에서더높은연구결과가나타났다. Hydroxy Radical 소거효과 Hydroxy radical은반응성이가장큰 free radical로 DNA 손상을일으켜세포독성이나돌연변이를유발하여체내에서전반적으로가장강한독성을나타내는 free radical이다 21,22). Hydroxy radical 소거율의결과는 Table 2와같다. 100 µl/ml 농도에서각각 85%, 75%, 84% 로표준물질인 vitamin C에비해매우높은항산화능을보였으며, 특히 262와 442가우수한 free radical 소거효과를보였다. 표준물질 vitamin C와비교하였을때 vitamin C의농도가 100 µl/ml 일때 262는 10배낮은 10 µl/ml에서약 3% Table 1.

Linoleic acid의자동산화능을이용한 thiocyanate법으로항산화활성을측정한결과는 Table 3과같다. 442 > 622 > 262 순으로각각 56%, 43%, 42% 의자동산화저해활성을보였으며농도의존적으로억제효과가나타났다. 자동산화억제효과는표준물질인 vitamin C 에비해활성이다소떨어지는것으로나타났으며, 기존에본연구실에서선행되어진개별연구결과인발효된홍삼 57% 12), 발효된미강 79% 13), 발효된대두 62% 14) 와비교하였을때또한낮은억제율을나타냈으며, 다른 radical 소거활성에비해서는활성이조금떨어지는것으로나타났다. Increasing Rate of Elastin Synthesis 콜라겐이외의탄력섬유인 elastin은주름형성에있어서많은관여를한다 25,26). 또한 UV에의해피부표피의각질형성세포 (keratinocyte) 에서도 elastase의전구체인 tropoelastin 의 mrna 발현이증가한다 27). Elastin synthesis를측정한결과는 Table 4와같다. 262, 622, 442 모두 100 Table 4. Inhibitory Effect of Rate Mixed Soybean, Rice Bran, Red Ginseng Fermented on elastin synthesis. 262 : soybean, rice bran, red ginseng mixed rate 2:6:2, 622 : soybean, rice bran, red ginseng mixed rate 6:2:2, 442 : soybean, rice bran, red ginseng mixed rate 4:4:2. a, b, c, d, are different group by one-way ANOVA with Duncan s post-hoc test Concentration Inhibition of anti-aging by using elastin synthesis (%) (µl/ml) ± 4.71a ± 2.12a ± 1.89a ± 1.89bc ± 0.69b ± 0.77b ± 2.22d ± 5.19cd ± 2.36bcd Table 5. Cell Viability of Rate Mixed Soybean, Rice Bran, Red Ginseng Fermented on melanoma cell. 262 : soybean, rice bran, red ginseng mixed rate 2:6:2, 622 : soybean, rice bran, red ginseng mixed rate 6:2:2, 442 : soybean, rice bran, red ginseng mixed rate 4:4:2. a, b, c, d, e, f, g are different group by one-way ANOVA with Duncan s post-hoc test Concentration Cell Viability (%) (µl/ml) ± 1.56g ± 1.17f ± 1.17cd ± 0.20de ± 2.93e ± 0.48b ± 2.15de ± 1.56c ± 0.39a µl/ml 의농도에서약 42% 로비슷하게나타났으며, 농도의존적인 elastin synthesis를보였다. 따라서 elastin 합성의증가는 elastase의활성을저해하며주름형성이나각질형성억제에도도움을줄수있을것으로보여진다. MTT를이용한세포독성측정 B16F10 cell은피부의색소를형성하는세포인 melanin cell의악성종양으로 melanin이과잉생산되어색소의피부침착에기인하여 B16F10 cell의성장을억제하면 tyrosinase

5 358 Jeong-Hyeon Son and Bae-Jin Ha 활성과 tyrosinase protein 발현을억제하여 melanin 생성을저해한다 28,29). B16F10의세포활성을측정해본결과는 Table 5와같다. 262에서가장낮은세포활성도인 19% 를나타내었고, 622와 442 순으로세포활성도를나타내었으며, 농도의존적인세포활성도를나타내었다. 요약 본연구는발효된대두, 미강, 홍삼 3종을배합을하여시너지효과를확인함으로써개별시료보다더욱더좋은혼합물을만들기위해서시행되었다. 3가지혼합비율 262, 622, 442를비교하였을때 442 비율이항산화활성과항노화활성이뛰어난것으로나타났다. 또한 442 혼합비율은개별재료의효과와비교하였을때개별홍삼보다높은시너지효과를보여주었다. 그러므로홍삼을원료로하여화장품을제조할때는홍삼을단독으로사용하는것보다미강과대두와혼합된 442 혼합비율재료가항산화활성과주름개선에더높은활성을가지는기능성화장품의중요원료로선호될수있다. 앞으로이물질에서주요한유효성분을분리, 정제하여항산화검증과항노화검증의필요성이있다고사료된다. 참고문헌 1.
