Antioxidant Activity of Methanolic Extract of Cordia dichotoma Collected from Different Geographical Region

Herbals are still used widely by World population, because of better compatibility with the human body and lesser side effects (Rawls R.1996). The antioxidative active of a total 11 genotypes of leaves and fruit materials of Cordia dichotoma by using different reagent. . The methanolic extract of leaves and fruit were screened for their free radical scavenging properties using ascorbic acid as standard antioxidant. Free radical scavenging activity was evaluated using 1, 1 diphenyl picryl hydrazine (DPPH) free radical. The methanolic extracts of leaves and fruits were screened for phytochemical constituents as per standard method. The extracts shows positive test for phenols, flavonoids, tannins and alkaloids among few genotype. The extracts that showed the greatest DPPH antioxidant activity of leaves were of NNd4 (54.23 %), NNd8 (54.33 %), NNd7 (53.09 %), NNd9 (50.45 %) and fruit extracts of NNd2 (58.09 %), NNd4 (54.23 %), NNd9 (52.12 %), NNd7 (51.06 %). The Leaves extracts that showed the greatest reducing power antioxidant activity was of NNd7 (48.23 %), NNd4 (43.66 %), NNd9 (42.89 %) and fruit extracts of NNd7 (45.12 %), NNd9 (41.94 %), NNd2 (44.76 %), NNd (40.65 %). The leaves and fruit extracts showed weak nitric oxide scavenging activity.
