36H: A Novel Potent Inhibitor for Antimelanogenesis

Table 2

DPPH free radical-scavenging property, reducing power, and chelating ability of 36H at different concentrations (10, 50, and 100 μM) are presented. The concentration of three specific positive controls, vitamin C, BHA, and EDTA, is 100 μM. The data is representative of 3 experiments as mean value ± SD.
