This plant has history of many health benefits local uses in Nagaland. Therefore, the main objectives of the present work are to explore the invitro antioxidant potentiality of methanol stem bark extract from the plant Oroxylum indicum indigenous to Nagaland. The stem bark was collected and air dried at room temperature and the extraction was done by successively Soxhlet apparatus. Total phenolic, total flavonoid were analyzed. Antioxidant capacity and free radical scavenging potentialities of the plant extract were done by performing several in vitro methods, viz; 1,1-diphnyl-2-picrylhydazyl (DPPH), reducing power assay and hydrogen peroxide scavenging activity. The results of phenolic and flavonoids were found to be highest in methanolic extract of the bark of Oroxylum indicum. The study shows that the plant has potential source of antioxidant and could be used for mitigating the detrimental effect of oxidative stress and reactive oxygen species-mediated disease and thus justifies its used in traditional medicine.
