Figure 3From: Alleviation effect of arbutin on oxidative stress generated through tyrosinase reaction with l-tyrosine and l-DOPAEffect of arbutin on hydroxyl radical formation. (a) Representative ESR spectra obtained by the addition of arbutin to the l-tyrosine-tyrosinase solution, and (b) the yield of DMPO-OH (mean + SD, n=3). Significant differences from the control are shown as P<0.01 (**).Back to article page
