Effect of combined A. lakoocha and G. glabra on cellular melanin content and tyrosinase activity. (a) Melanin pigments (black) in B16 cells (pink) observed under a light microscope (Magnification ×100); (b) the number of melanin containing cells from a total of 1000 cells counted under a light microscope; (c) cellular melanin content; (d) cellular tyrosinase activity. Cells were treated with combinations of Al95 and Gg95 at a final concentration of 0.1 mg/mL in several ratios for 48 h. The data are means ± SD from three independent experiments. The superscript letters (*) indicate significant difference at p < 0.01.
