In order to investigate the potential of Nigella sativa (N. sativa) oil as an active ingredient for whitening cosmetics, we prepared N. sativa oil. We measured its inhibitory effects on mushroom tyrosinase activity, cellular tyrosinase activity, and melanin synthesis inhibitory activity in B16 melanoma cells. N. sativa oil and its components showed inhibitory activity against mushroom tyrosinase and melanin synthesis. In a melanin synthesis inhibition assay using mouse B16-F10 melanoma cell, it reduced melanin production up to 86 % at a concentration of 10 mg/mL without cytotoxicity. In the study on the melanogenic protein expressions by using RT-PCR and Western blot, N. sativa oil and its components inhibited expression of tyrosinase protein, which is a well-known key protein on melanogenesis, and tyrosinase expression was gradually decreased in a dose-dependent manner. Therefore, this result suggests that N. sativa oil could be used as an active ingredient for whitening cosmetics.

니겔라 사티바(Nigella sativa Linn.) 오일의 미백 효능을 확인하기 위하여 니겔라 사티바 오일 및 오일에서 분리된 유효성분들을 버섯 타이로시네이즈 효소, B16 멜라노마 세포를 이용하여 멜라닌 생성에 관련된 다양한 실험을 실시하였다. B16-F10 멜라노마 세포를 이용한 멜라닌 저해 활성시험 결과에서 니겔라 사티바 오일은 10 mg/mL의 농도에서 약 86 %의 멜라닌 생성을 억제하였으며, RT-PCR과 Western blot을 통한 멜라닌 생성 기작에 대한 영향을 조사한결과, 멜라닌 합성의 주요 단백질인 타이로시네이즈 발현 저해효과가 우수하게 나타났다. 또한, tyrosinase related protein-1 (TRP-1) 및 tyrosinase related protein-2 (TRP-2)의 발현이 억제되는 것을 확인하였다. 따라서, 니겔라 사티바오일은 멜라닌 생합성 저해 효과뿐만 아니라, 멜라닌 합성에 필수적인 효소(타이로시네이즈, TRP-1, TRP-2)의 발현저해를 통해 미백 효과를 나타내는 것으로 확인되었으며, 이에 따라 니겔라 사티바 오일은 멜라닌 생합성을 저해하는미백 소재로 활용할 수 있을 것으로 사료된다.
