  • Abstract

    Moringa oleifera is a major tropical plant with highly valued nutritional and medicinal properties. The present study is undertaken to analyze the phytochemistry and antioxidant activity of the flowers of this plant and study the influence of the geographical properties on them. Antioxidant activities of extracts of M. oleifera flowers from four different districts of Tamilnadu, India with varying geographical properties, were investigated. Free radical scavenging potential was evaluated in vitro by using diphenyl-picryl-hydrazyl (DPPH) assay. Other antioxidant assays like Hydroxyl radical scavenging assay, Superoxide Anion Radical scavenging assay, Metal chelating assay, Phosphomolybdenum assay, Ferric thiocyanate (FTC) method, Thiobarbituric acid (TBA) method were also adopted. Phytochemicals in the flower extracts were screened qualitatively. Phenol and flavonoid contents of the samples were estimated. Significant differences were observed in the antioxidant machinery of the extracts. Though the presence of phytochemicals among the samples remained the same, their quantity varied as noticed from their phenol and flavonoid contents which correlated to their antioxidant activities. The methanol extract of M. oleifera flowers from Tirunelveli district with loamy red soil, moderate monsoon and less pollution, exhibited the highest antioxidant potential. Its phenol and flavonoid contents also seemed to be maximum when compared with the other samples. Results suggested the profound effect of geographical properties on the phytochemical composition which further influenced the antioxidant potential of M. oleifera flowers.
