This study investigates the phytochemical properties and anti-cataract activity of the ethanolic extract of Terminalia arjuna bark. Terminalia arjuna, a medicinal plant traditionally used in Ayurvedic medicine, is known for its cardioprotective and antioxidant properties. Comprehensive phytochemical screening of the ethanolic extract revealed the presence of key bioactive compounds, including flavonoids, tannins, saponins, and glycosides, which are indicative of its therapeutic potential. The anti-cataract activity was assessed using an in vitro model of cataractogenesis induced by hydrogen peroxide. The results demonstrated that the ethanolic extract of Terminalia arjuna significantly inhibited the formation of cataracts, likely due to its potent antioxidant properties that mitigate oxidative stress. These findings suggest that Terminalia arjuna bark extract could be a promising natural agent for the prevention and management of cataracts, warranting further in vivo studies and clinical trials to fully establish its efficacy and safety in ocular health
