In the present work, we have examined the antioxidant activity of the aqueous extract of Morinda citrifolia fruit using phosphomolybdenum test and reducing power assay methods. With the help of a soxhlet apparatus, distilled water was used as the extraction solvent to get the fruit powder. The total phenolic content in the leaf extract was measured analytically using Folin-Ciocalteu reagent method. The IC50 of extract in blocking phosphomolybdenum radial was found to be 140.45 µg/mL. The data for reducing power show that the extract was able to reduce the ferricyanide within 20 minutes of interaction and hence is powerful antioxidant. From this the study, the ability of the extract to inhibit phosphomolybdenum and also to cause effective decrease of free radicals has been proven
