초록

본 연구는 윈터체리 추출물의 미백 활성을 검증하여 기능성 미백 소재로서의 가능성을 확인하였다. 먼저, DPPH, ABTS, FRAP를 이용한 항산화 활성 검증에서 윈터체리 추출물은 매우 높은 항산화 효과를 보였으며, 티로시나아 제의 활성에도 농도 의존적인 억제 효과를 보여주었다. 마우스 유래 B16-F10 멜라노마 세포를 이용한 멜라닌 생성에서 윈터체리 추출물이 미치는 영향을 확인한 결과, 세포 내에서 생합성 되는 멜라닌의 양이 상당히 감소하고 있음을 확인하였다. 또한, 멜라닌 생성을 더욱 유도하는 ${\alpha}-MSH$를 세포에 처리하였을 때, 윈터체리 추출물은 농도 의존적인 억제 효능을 보여주었다. 이러한 윈터체리 추출물의 멜라닌 생성 억제는 MITF 전사인자의 발현을 억제함으로써 일어나고, 결과적으로 멜라닌 생합성과 관련된 티로시나아제와 Tyrp-1 등의 단백질 발현을 감소시킴으로써 일어나게 됨을 확인하였다. 이러한 결과들로 볼 때, 윈터체리 추출물은 기존의 미백 원료들을 대체할 수 있을 뿐만 아니라 함께 사용할 경우 상승 효과를 낼 수 있는 새로운 미백 소재로 활용될 수 있을 것이다.

Withania somnifera has been used in folk medicine to treat various ailments for centuries. In this studies to investigate the whitening effect of Withania somnifera extracts as an active ingredient for whitening cosmetics, the antioxidant capacity and the effects of Withania somnifera extracts on melanogenesis in B16-F10 melanoma cells were identified. Withania somnifera extracts significantly reduced both tyrosinase activity and melanin content in a concentration-dependent manner. Furthermore, it was found that Withania somnifera extracts decreased ${\alpha}-MSH$ (melanocyte-stimulating hormone)-induced tyrosinase activity and MITF(microphthalmia associated transcription factor) protein expression. These data indicate that Withania somnifera extracts attenuate ${\alpha}$-MSH-stimulated melanin synthesis by modulating MITF expression and that they may be a useful therapeutic agent for treating hyperpigmentation and an ingredient of whitening cosmetics.
