J. AOAC Int. 106, 1598-1607 (2023). HPTLC bioautography of Rubia cordifolia on silica gel impregnated with kojic acid with toluene - ethyl acetate - formic acid 5:4:1. Antityrosinase activity by spraying with 2 mM L-tyrosine and incubated at room temperature for 10 min. The plate was the sprayed with tyrosinase solution (1 mL of mushroom tyrosinase enzyme (3333 units) in 10 mL PBS - sodium phosphate buffer solution, pH 6.8), followed by incubation at room temperature for 45 min. Clear white zones of tyrosinase enzyme inhibition allowed the detection of presence of active compounds. Further analysis by MS allowed the identification of purpurin with antityrosinase potential.
