Fig. 3From: Tyrosinase inhibitory activity of flavonoids from Artocarpus heterophyllous Lineweaver–Burk plots for type of inhibition of mushroom tyrosinase (10 U/mL) by artocaepin E (1) for the catalysis of l-DOPA (0.2, 0.3, 0.4, 0.5, and 0.6 mM) at 30 °C, pH 6.8. Concentration of these compounds for curves I0.0, I5.0, I7.0, and I10.0 were 0.0, 5.0, 7.0, and 10.0 μM, respectively. The inset represents the plot of these compounds for determining the inhibition constant (Ki). The line is drawn using a linear lest squares fitBack to article page
