Abstract

In order to investigate the potential of a Dayflower (Commelina communis L.) extract as an active in gredient for whitening cosmetics, we prepared aqueous Commelina communis L. extract We measured its mushroom tyrosinase inhibitory activity, cellular tyrosinase activity, and melanin synthesis inhibitory activity in B16 melanoma cells. It did not show inhibitory activity against mushroom tyrosinase but showed melanin synthesis inhibitory activity. In a melanin synthesis inhibition assay using mouse B16-F10 melanoma cell, it suppressed melanin production up to 32% at a concentration of $1,000{\mu}/mL$ without cytotoxicity, and also reduced cellular tyrosinase activity to above 50 % above the concentration of $250{\mu}g/mL$. In study on the melanogenic protein expressions, it had especially influence on expression of tyrosinase protein, which is a well-known key protein on melanogenesis, and tyrosinase expression was gradually decreased in a dose-dependent. Dayflower also blocked N-glycosylation of TRP-2, but affected on the expression of TRP-1 rather than on blocking of N-glycosylation processing. Therefore, this result suggests that aqueous Commelina communis L. extract could be used as an active ingredient for whitening cosmetics.

닭의장풀(Commelina communis L. Dayflower) 추출물의 미백효능을 확인하기 위하여 B16 melanoma 세포를 이용하여 melanin 생성에 관련된 다양한 실험을 실시하였다. 닭의장풀 추출물은 버섯 tyrosinase 활성 실험에서 저해 효과를 보이지 않았으나, melanin 생성 저해효과를 나타내었다. B16-F10 멜라노마 세포를 이용한 활성시험 결과에서, 닭의장풀 추출물은 1,000 ${\mu}g/mL$의 농도에서 약 32%의 멜라닌 생성을 억제하였으며, 세포내 티로시나제 활성 억제 능도 우수하여 닭의장풀 추출물 250 ${\mu}/mL$ 이상의 농도에서 50% 이상의 저해 효과를 보였다. 추출물의 생성 기작에 대한 영향을 조사한 결과, melanin 합성의 key protein 인 tyrosinase 발현의 우수한 저해 능력을 보였고, tyrosinase related protein-1 (TRP-1)의 발현 억제와 tyrosinase related protein-2 (TRP-2)의 N-glycosylatin 억제를 통해 melanin 합성이 억제되는 것으로 분석되었다. 따라서 닭의장풀 추출물은 melanin 합성에 필수적인 효소(tyrosinase, TRP-1)의 발현 저해 및 TRP-2의 N-glycosylation 억제를 통해 미백 효과를 나타내는 것으로 확인되었으며, 이에 따라 본 추출물은 melanin 합성의 효소 경로를 저해하는 미백 소재로 활용할 수 있을 것으로 사료된다.
