Abstract

Background: This project aimed to evaluate the anti-melanogenic characteristics of Nasturtium officinale (N. officinale) by assessing the impact of both aqueous and hydroalcoholic extracts on the inhibition of cellular and mushroom tyrosinase enzymes, as well as the suppression of the melanin synthesis in B16F10 melanoma cells. Methods: The aerial components of N. officinale were subjected to extraction using distilled water: ethanol (7:3) through the maceration technique. The extract’s phenolic compounds were quantified employing the Folin-Ciocalteu method. The evaluation of the safety profile of the extracts on B16F10 cells was done by the MTT assay. Subsequently, the melanin concentration in B16F10 cells, alongside the inhibitory effects on both mushroom and cellular tyrosinase, was assessed following treatment with the aforementioned extracts. Results: The aqueous and hydroalcoholic extracts exhibited no significant toxicity on B16F10 when compared to Phosphate-Buffered Saline (PBS). Additionally, there was no notable difference in the cytotoxic effects of extracts on the B16F10 cell line. Both extracts resulted in inhibition of cellular and mushroom tyrosinase, along with a decrease in melanin levels in B16F10 in a concentration-dependent manner. Ultimately, the total phenolic content in the aqueous and hydroalcoholic extracts was found to be approximately 14 and 30 mg/g of gallic acid, respectively. Conclusion: This in vitro investigation offers evidence supporting the skin brightening properties of N. officinale as an anti-melanogenic agent. Given its safety profile and absence of toxic effects on melanoma cells, it may be incorporated into the formulation of skin-brightening products following preclinical tests. © 2026, Avicenna Journal of Medical Biotechnology.
