Effects of plant extracts on the activities of human and mushroom TYRs. The activities of human TYR (a) and mushroom TYR (b) were determined in the absence or presence of plant extract (100 µg mL⁻¹) or arbutin (80 µg mL⁻¹). Data are presented as percentages of uninhibited activities (means ± SE, 𝑛=3). ^∗𝑃<0.05 versus vehicle control.
