Abstract
Phytochemistry and antioxidant activity of Irvingiagabonensis (Bush mango) seed sample were evaluated. Dried milled seeds of I.gabonensis popularly known as “ogbono” passed through phytochemical screening, Gas chromatography-mass spectrometry (GC-MS) analysis and antioxidant studies. Tannins, saponins, flavonoids, alkaloids, steroids, and reducing sugars were among the phytochemicals found present after screening. About 20 constituents were revealed by the GC-MS analysis out of which 1,3-O-Benzylidine glyceryl-2-myristate had the highest molecular weight, 2-Undecanone had the highest peak area of 45.39% whereas 3-Dibenzofuranamine had the highest retention time. Some of these constituents could have one or two applications in medicinal, food or cosmetic industries. I.gabonensis seeds showed better antioxidant activity against the control at concentrations considered in this study. Some of these constituents as well could be behind the observed antioxidant activity. This study has evaluated the phytochemistry and antioxidant activity of I.gabonensis (Bush mango) seed sample.
