It has been shown to exhibit numerous biological and pharmacological properties, including antiviral, antibacterial, and antitumor activities in numerous human cancer cell lines. Gallic acid is a water soluble phenolic acid present in grapes and in the leaves of many plants. Apart from its phytochemical role, gallic acid is also used in tanning, ink dyes, and the manufacture of paper. To investigate the relation between GA's inhibition of melanogenesis and antioxidant activity, the effect of GA on reactive species (RS) generation and the reduced glutathione (GSH)/oxidized glutathione (GSSG) ratio in were determined in B16 cells. The diverse range of applications of this simple polyphenol is due to a fine amalgam between its antioxidant and prooxidant potential. E-mail:
