This study investigates the role of flavonoids in combating UV-induced oxidative stress and skin cancer. It aims to fill a research gap by extracting and fractionating galls with solvents, focusing on the ethyl acetate fraction identified through phytochemical profiling. The bioactivity is assessed through antioxidant assays, UV absorption measurements, and anticancer evaluations on A431 cells, providing insights into the photoprotective and anticancer potential of flavonoids.
