The Effect of Volatile Oil from Vernonia anthelmintica Seeds on Melanin Synthesis in B16 Cells and Its Chemical Analysis by GC-QTOF-MS

Figure 1

B16 melanoma cells were exposed to various concentrations of AVO (1, 5, 10, 20, 30, and 50μg⋅mL⁻¹) for 24h. Cell viability was measured by a CCK-8 assay. The data are shown as the means ± SD; n=3.
