Fig. 1. Effect of Korean Red Ginseng (KRG) on tyrosinase activity. Total extract or saponin of KRG (100, 50, 25, 12.5, 6.25, and 3.125 ppm) was incubated with tyrosine cell extracts for 60 min at 37℃. Absorbance was measured at 490 nm. Data are shown as average±SEM. *p<0.05, compared with the control.
