In Vitro Phytochemical Screening and Antioxidant Activity of Jamun (Eugenia jambolana Linn) Plants Parts Collected from Lahore, Pakistan
Our research work based on the qualitative and quantitative phytochemical studies including the antioxidant activity of extracts (ethanolic and aqueous) obtained from leaf, stem and seed of Eugenia jambolana plant. Qualitatively phytochemical analysis was done by biochemical testing, quantitative estimation was taken spectrophotometrically and antioxidant activity of extracts was tested by DPPH radical scavenging. Qualitative and quantitative outcomes of our study explain that ethanol is applicable solvent system that comprises high quantity of bioactive compounds than water solvent system. Antioxidant activity revealed that ethanolic leaf, seed and stem extracts removed free radicals 68%, 98% and 33% respectively in contrast with water extracts of leaf, seed and stem 5.09%, 1.25% and 7.26% respectively. Ascorbic acid was taken as standard that kills 97% free radical species. Extracts in ethanol solvent system displayed protruding antioxidant activity and also contains high amount of phtyo-chemicals.
