- Abstract
Free radicals are highly reactive species produced in the body during normal metabolic functions or introduced from the environment, which are capable of causing tissue injury and have been implicated in the pathology of various human diseases. Antioxidants act as a major defense against radical-mediated toxicity by protecting against the damages caused by free radicals. A number of plants and plant isolates have been reported to protect free radical induced damage in various experimental models Couroupita guianensis were widely used for the treatment of gastritis, scabies, bleeding piles, dysentery and scorpion poison. The different solvent extracts of the dry and fresh flowers was studied for its free radical scavenging activity with different methods viz lipid peroxidation assay, reducing activity and hydrogen peroxide scavenging assay. Along with these various levels of enzymatic and non-enzymatic antioxidants were also estimated. Further, polyphenols were also identified by RP-HPLC. The results showed that methanol extracts of dry flowers exhibit high phenolic content and antioxidant activities, interestingly aqueous extracts exhibit high enzymatic antioxidants.
