ABSTRACT

Variation in the phytochemical and antioxidant activity of methanol and n-Hexane extract of leaf, barks, twig and root of G. arborea growing in different agroclimatic regions was evaluated. The methanol and n-Hexane extracts of plant parts were screened for the qualitative and quantitative analysis of phytochemicals and antioxidant activities such as DPPH and Metal chelating activity. The study revealed that the presence of carbohydrates, fatty acids, phenols, alkaloids, flavonoids, tannins, saponins, terpenoid and sterols in all the plant parts of G. arborea collected from different geographical regions. The plants from site III and site IV were found to have relatively high secondary metabolites within the antioxidant property than that of the samples from the site I & II. As a good resource of sampling material, G. arborea may have beneficial medicinal values.
