Cell viability (MTT assay), tyrosinase activity (L-DOPA assay), and melanin content were measured. &lt;strong&gt;Results:&lt;/strong&gt; GC-MS identified 9,12-octadecadienoic acid methyl ester (E,E) as the predominant compound (45.88%), while HPLC confirmed a relatively low TQ concentration (0.04%). EE BCS maintained &amp;gt;90% cell viability at concentrations up to 12.50 ppm and exhibited an IC50 of 56.41 ppm. Tyrosinase activity significantly increased at 6.25 ppm (136.40%; &lt;em&gt;p&lt;/em&gt; &amp;lt; 0.05) and 12.50 ppm (228.10%; &lt;em&gt;p&lt;/em&gt; &amp;lt; 0.01), accompanied by a significant elevation in melanin content (226.00%; &lt;em&gt;p&lt;/em&gt; &amp;lt; 0.05 and 266.90%; &lt;em&gt;p&lt;/em&gt; &amp;lt; 0.01 respectively). &lt;strong&gt;Conclusion: &lt;/strong&gt;EE BCS can effectively promote melanogenesis, despite containing low levels of thymoquinone, potentially through synergistic actions of its phytochemical constituents. Given its region-specific phytochemical richness, Indonesian &lt;em&gt;N. sativa&lt;/em&gt; extract holds promise as a natural therapeutic candidate for vitiligo. Further &lt;em&gt;in-vivo&lt;/em&gt; and clinical validation is warranted.&lt;/p&gt;

Finding a potent medicinal plants that can prevent pigment disorder. Objective: This study was to investigate the potential of leaf extract from&lt;em&gt; Azadirachta indica&lt;/em&gt; var &lt;em&gt;siamensis valeton&lt;/em&gt; to inhibit melanin formation or melanogenesis. &lt;strong&gt;Materials and Methods: &lt;/strong&gt;&lt;em&gt;A.indica&lt;/em&gt; leaf extract was tested for phenolic and flavonoid content assay. Tests using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay were administered to determine the toxicity of &lt;em&gt;A.indica &lt;/em&gt;leaf extract in B16F10 melanoma cells. Melanin content and tyrosinase activity assays were used to determine the potential for the inhibition of melanogenesis. Data was analyzed using SPSS. &lt;strong&gt;Results: &lt;/strong&gt;It was found that &lt;em&gt;A.indica &lt;/em&gt;leaf extract per gram has a total phenolic content of 28.73 ± 0.30 mg gallic acid equivalents and flavonoid of 12.48 ± 0.00 mg rutin equivalent. In addition, we found that these herbal extracts decreased the melanin content and intracellular tyrosinase activity in B16F10 melanoma cells without any toxicity. This study suggested that the melanin content and intracellular tyrosinase activity in B16F10 melanoma cells were decreased without any cytotoxicity by the &lt;em&gt;A.indica&lt;/em&gt; leaf water extract. &lt;strong&gt;Conclusion:&lt;/strong&gt; The findings demonstrated that &lt;em&gt;A.indica&lt;/em&gt; leaf water extract inhibits melanin production through reducing tyrosinase activity. These results could be useful as a therapeutic treatment for skin hyperpigmentation disorders as well as an effective ingredient in whitening cosmetics.&lt;/p&gt;
