Assessment of Anti-oxidant and Photocatalytic Activity of Pamburus missionis Swingle Extracts through GC-MS and ICPOES Analysis

In this current world of polluted environment, antioxidants play a vital role in mitigating oxidative damage and protecting against harmful effects on human health and the environment by neutralising free radicals.The photocatalytic activity can facilitate the degradation of pollutants and toxic substances.Therefore, the exploration of novel antioxidant and photocatalytic agents from natural resources such as plant extracts is integral for the development of effective therapeutic strategies and tenable solutions to combat these pressing issues.Pamburus missionis, a rutaceae member which is native to India and Southeast Asia, has been used in Ayurveda with the name "Kudangal" for different types of digestive, respiratory and skin problems.Phytochemical analysis revealed the presence of alkaloids, flavonoids, phenols, glycosides and steroids.GC-MS analysis unveiled totally 8 compounds from leaf, 5 and 8 from stem and bark extracts.ICP-OES analysis disclosed the different mineral elements such zinc (Zn), iron (Fe), copper (Cu), magnesium (Mg) and so on.In DPPH (2, 2-diphenyl-1-picrylhydrazyl) free radical scavenging assay, bark extract showed highest antioxidant property ( 81.99%) followed by leaf(69.34%) and stem (48.42%).The leaf extract exhibited good photocatalytic activity (80.50%) followed by bark( 72.88%) and stem, (55.72%).The present study demonstrated the antioxidant and photocatalytic potential of .
