This study reports quantitatively ethanol, acetone and water extracts of Aloe saponaria for total phenols, flavonoids, mineral (Cu, Mn, Zn, Fe) contents and antioxidant activity. Maximum concentration of total phenols (0.019 mg GAE g−1 in water extract), flavonoids (3.60 mg CE g−1 in water extract) and Cu, Mn, Zn and Fe in ethanol, water, water and acetone extracts respectively, were observed. Best antioxidant activity (47.1%) was shown by ferric thiocyanate method in water extract and the highest antiradical activity (75.0%) by diphenyl-1-picrylhydrazyl free radical scavenging method was shown by water and ethanol extracts. A significant linear correlation was observed between the total phenols and antioxidant activity of plant extracts.
