Ferulic acid is an organic Chemicals which is an abundant phenolic phytochemical found in plant cell wall components such as arabinoxylans as covalent side chains. Ferulic acid is a precursor in the manufacture of other aromatic compounds. It is an antioxidant in the sense that it is reactive toward free radicals such as reactive oxygen species (ROS). ROS and free radicals are implicated in DNA damage, cancer, accelerated cell aging. In addition, it may have pro-apoptotic effects in cancer cells, thereby leading to their destruction. What\'more, Ferulic acid may be effective at preventing cancer induced by exposure to the carcinogenic compounds benzopyreneand 4-nitroquinoline 1-oxide
