Tyrosinase has an important role in melanin formation, is responsible for the production of colour pigments of skin, hair, and eye. In the presents study, tyrosinase was isolated from Mushrooms, isolation of enzyme was done by acetone precipitation procedure and precipitation of enzyme was done with ammonium sulphate precipitation method. Plants selected for extraction were Azadirachta indica (Neem), Manikara zapota (Chiku), Annona squamosa (Sitaphal), and Hibiscus Rosa-sinesis (China rose). For phytochemical screening Alkaloids-Mayer’s Test, Flavonoids (Shinoda Test, Alkaline Reagent Test), sugar (Benedict’s reagent Test), Glycosides (Borntrager's Test), Phenolic compounds Test (Ferric chloride Test, Gelatin Test, Lead Acetate Test). Mushroom tyrosinase inhibitory assay was determined by the spectroscopic method. The study shows the tyrosinase inhibitory activity of selected medicinal plants.

Tyrosinase inhibitory activity was studied on the crude extracts and flavonoids successfully isolated from the leaves and heartwoods of Artocarpus lowii King. The flavonoids were fully characterized spectroscopically as isobavachalcone (1), 4-hydroxyonchocarpin (2), 2',4'-dihydroxy-4-methoxy-3'-prenyldihydrochalcone (3), 2',4'-dihydroxy-3,4-(2",2"-dimethylchromeno)-3'-prenyldihydrochalcone (4), artocarpin (5), cycloheterophyllin (6) and 4',5-dihydroxy-6,7-(2,2-dimethylpyrano)-2'-methoxy-8-γ,γ-dimethyl allylflavone (7). Tyrosinase inhibitory activity of the samples was determined against mushroom tyrosinase using ELISA microplate reader. Cycloheterophyllin (6) exhibited an excellent inhibitory activity against mushroom tyrosinase comparable to the standard kojic acid with the IC50 value of 52.5 µg/mL (88.3%).
