Figure 1From: Alleviation effect of arbutin on oxidative stress generated through tyrosinase reaction with l-tyrosine and l-DOPAHydroxyl radical formation by L-tyrosine-tyrosinase reaction. (a) Representative ESR spectra with different concentrations of l-tyrosine, and (b) the yield of DMPO-OH (mean ± SD, n=3 or 4).Back to article page
