Abstract

Monoterpenoids were recently found as main biologically active compounds which is responsible for various physiological effect in goat's beard (Aruncus dioicus). Ethyl acetate extract of A. dioicus (ADE) was treated to B16F10 melanoma cells for the examination of whitening activity. MTT assay was performed to evaluate cell toxicity and the result showed that slight cell toxicity (> 10%) by over $500{\mu}g{\cdot}mL^{-1}$. Thus, 0, 5, 10, or $50{\mu}g{\cdot}mL^{-1}$ ADE was used for further experiments. We found that tyrosinase activity was decreased according to ADE concentration, and the total melanin content was also dramatically reduced. Especially with $50{\mu}g{\cdot}mL^{-1}$ ADE treatment tyrosinase activity was reduced to 35.6%, and 58.8% of melanin content was lowered. In addition, whitening related proteins including tyrosinase, tyrosinase related protein 1 (TRP1), TRP2, microphthalmia associated transcription factor (MITF) and cAMP and protein kinase A (PKA) were reduced by ADE treatment. It caused decreased phosphorylation of cAMP response binding protein (CREB) but increased phosphorylation of extracellular signal related kinase (ERK). Therefore, in this paper we would like to suggest the potent usage of A. dioicus natively grown in Ulleungdo, Korea as materials of functional cosmetics by confirming whitening activity related with melanin content.

울릉도 자생 삼나물(Aruncus dioicus)은 최근 monoterpenoids 생리활성 물질이 밝혀지면서 여러 가지 항산화와 관련된 생리활성이 확인되고 있다. 삼나물 ethyl acetate 분획물에 의한 미백효과를 검증하기 위하여 흑색세포종인 B16F10을 이용하여 실험을 진행하였다. 삼나물 ethyl acetate 분획물(ADE)의 세포독성을 측정하기 위하여 MTT assay를 실시한 결과, ADE $500{\mu}g{\cdot}mL^{-1}$ 이상의 농도에서 미비한 세포독성(10% 이상)을 확인하였으며, 이후 실험에서는 5, 10, $50{\mu}g{\cdot}mL^{-1}$ 농도가 세포 내에서 tyrosinase 활성과 멜라닌 양의 변화를 측정하였다. 그 결과 ADE 농도에 따라 tyrosinase 활성이 감소하고 총 멜라닌 함량이 감소하는 것을 확인하였다. 특히 $50{\mu}g{\cdot}mL^{-1}$에서 35.6% tyrosinase 활성억제, 58.8% 멜라닌 함량이 감소하는 것을 확인하였다. 또한 ADE에 의해 미백과 관련된 tyrosinase, tyrosinase related protein 1(TRP1), TRP2, microphthalmia associated transcription factor(MITF) 및 그 상위 단계인 cAMP와 protein kinase A(PKA)의 단백질 양이 감소하여 cAMP response binding protein(CREB)의 인산화는 감소하고 extracellular signal related kinase(ERK)의 인산화는 증가하는 것을 확인하였다. 본 연구에서는 울릉도 자생 삼나물의 미백효과에 관한 효능을 확인하고 기능성화장품의 소재로서의 활용 가능성이 있음을 확인하였다.
