abstract
This work presents Phytochemical Screening, Gas Chromatography Mass Spectroscopy Studies and Antioxidant Property of aqueous extract of Ogbono (Irvingia gabonensis). Standard chemical and biochemical chemicals and analytical techniques were used for this study. The phytochemical screening of the of the samples showed the presence of various secondary metabolites of which alkaloids, flavonoid, cardiac glycoside andalkaloids are moderately present while tannis, saponins, steroids, protein and reducing sugar were the most prominent as shown in the results. Antioxidant activities of Ogbono (Irvingia gabonensis) determined by the free radical scavenging activity (DPPH) assay method indicated a steady increase in the scavenging activity of free radicals in all extracts. It was observed that the ability of test materials to scavenge DPPH was assessed on the basis of their I_C50 values, defined above as the concentration of test material to reduce the absorbance at 515 nm of DPPH solution to half of its initial value. The high antioxidant potential, free radical scavenging activity and antioxidative enzymes of Ogbono (Irvingia Gabonensis) should be utilized to develop new drug contenders for antioxidant remedy.
