Skin whitening and anti-aging effects by using Lactic acid bacteria fermentation at room temperature

상온 발효 유산균 배양액을 이용한 피부 미백 및 항노화 효과

초록/요약 도움말

이 연구의 목적은 상온발효 유산균 Enterococcus faecium MSS2 균주를 Vigna angularis와 Hizikia fusiforme 열수추출물에 접종하여 발효추출물을 제조하고 미백 및 항주름 개선을 위한 부작용이 적고 안정성을 가진 천연물 소재로서의 가능성을 보고자 하였다. 상온발효 유산균 Enter-ococcus faecium MSS2 균주를 V. angularis와 H. fusiforme 열수추출물에 접종하고 72시간 동안 시대별로 발효시켰다. 모든 발효군에서 발효시키지 않은 추출물에 비해 생리활성을 증가하였고, 미백 및 항주름 효과에 있어서 48시간 발효시킨 추출물에서 우수한 활성을 보였다. 이후 48시간 동안 발효시킨 V. angularis 와 H. fusiforme 추출물을 이용하여 세포 내에서의 미백 및 항주름 효과를 확인하였다. B16F10 흑색 종 세포와 피부섬유아세포 CCD-986SK 세포에서의 발효추출물의 세포독성을 확인한 결과, 100 μg/ml 농도에서까지 80%이상의 세포생존률을 보였다. 이후 B16F10세포에서의 멜라닌 형성 억제 효과 및 티로시나아제 활성 억제 효과를 확인한 결과, 두 추출물 모두 농도의존적으로 효과를 보였다. 또한 멜라닌 생성과 조절에 관여하는 tyrosianse, TRP-1의 발현량과 항주름에 주로 관여하는 MMP-1, MMP-12의 발현량을 웨스턴 블랏팅 분석법을 이용해 측정하였다. 그 결과, V. angularis와 H. fusiforme 발효추출물은 100 μg/ml에서 미백 및 항주름에 대한 효과를 확인할 수 있었다. 다름 실험들을 통해 상온발효 유산균 Enterococcus faecium MSS2를 Vigna angularis 와 Hizikia fusiforme 에 접종시킨 발효추출물은 미백 및 항주름 화장품 소재로서 응용할 가치가 있을 것이라 사료된다.

초록/요약 도움말

The aim of this study was to discover the possible uses of Vigna angularis and Hizikia fusiforme in developing cosmetic materials for whitening, antioxidant and anti-wrinkle functions. Lactic acid bacteria isolated from traditional fermented foods were inoculated and cultured within V. angularis and H. fusiforme water extract for 72 hours separately. The 48 hours fermented V. angularis and H. fusiforme samples were evidenced with IC50 values for tyrosinase inhibitory activity as 0.43 mg/mL, 0.38 mg/mL and EC50 values for DPPH radical scavenging activity as 0.80 mg/mL, 0.89 mg/mL respectively. Furthermore, both extracts with the highest activities experimented on their inhibitory effect on melanin formation in B16F10 melanoma cells and western blotting analysis revealed the reduction of protein expression in B16F10 melanoma cells by 48 hours fermented samples. Moreover, we examined the inhibitory effect of 48 hours fermented extract on collagenase and elastase inhibitory activity in CCD-986SK fibroblast cells. According to the findings of the research V. angularis and H. fusiforme water extract with 48 hours fermentation revealed the highest tyrosinase inhibitory activity, DPPH radical scavenging activity and anti-wrinkle activity with its possible use as cosmetic materials.
