The methanolic extract of Morinda tinctoria leaves showed IC50 with minimum concentration and more effective in scavenging DPPH, NO, H2O2 and Hydroxyl radicals followed by ethanol and ethyl acetate extracts respectively. Thus, the methanolic extract of Morinda tinctoria leaves can be recommended as a potent antioxidant in patients suffering from various oxidative degenerative diseases such as cancer, diabetes, arthritis, and cardiovascular diseases. This free radical scavenging activity might be due to the active components present in the methanolic extract of Morinda tinctoria leaves.
