Figure 5.

The CE analysis of (black trace) mangiferin solution in 50 mM phosphate buffer (pH 6.8) and its mixture with tyrosinase at the concentration of (red trace) 0.025 mg mL⁻¹, (blue trace) 0.05 mg mL⁻¹, (violet trace) 0.1 mg mL⁻¹, (dark green) 0.15 mg mL⁻¹, and (light green) 0.2 mg mL⁻¹. The mangiferin concentration was constant in all solutions (0.3 mg mL⁻¹). Imp—mangiferin impurity; the numbers indicate certain complexes of mangiferin with the enzyme.
