Figure 1: Intracellular anti-tyrosinase activity and melanin content. Arbutin, kojic acid = positive control. A1, A2, A3 and A4 = petroleum ether, ethyl acetate, methanol, water extracts of Artocarpus chama stem, respectively. S1, S2, S3 and S4 = petroleum ether, ethyl acetate, methanol and water extracts of Streblus taxoides wood, respectively. A1, A3, A4, S1, S3, S4 = 100 µg/mL, A2 = 5 ug/ml, S2 = 50 µg/mL. Data are expressed as mean ± standard deviation from three independent experiments. *P < 0.05, **P < 0.01 and ***P < 0.001 indicate a significant difference from control group
