Efficacy comparison of L-tyrosine and L-DOPA for tyrosinase-based TLC bioautography after a 10-minutes reaction (amount of tyrosinase was 2 units per spot). (a) Results of various amounts of L-tyrosine and L-DOPA on tyrosinase-based TLC plate. (b) Quantification of melanin spots on TLC plates of 20, 40 and 60 nmol L-tyrosine and L-DOPA groups using ImageJ. *Indicates that the color depth of spots on TLC of L-DOPA groups are significantly higher than that of L-tyrosine groups (p < 0.05).
