Tyrosinase inhibition assay
The various parts of IC in different solvents were studied for their skin whitening property through tyrosinase inhibition (Fig 1).
Methanolic extracts exhibited the highest inhibition of tyrosinase followed by aqueous and petroleum ether extracts in comparison to the solvents. Among the methanolic extracts of various parts of IC, flowers ranked first followed by bark and leaves. The aqueous extract of bark (49.35%)
