Natural products are obtained from different plants and are considered a potential source of biologically active compounds. The pharmacological and therapeutic properties of these bioactive compounds remain the subject of research. Aloe vera is a cosmetic, medicinal and ornamental plant and it is a perennial succulent herb that grows in tropical and subtropical regions of the world. It is considered as a magical plant which has vast benefits in medicinal history. Its medicinal properties make it worthy for so many health aspects. In this study, phytochemical screening and in-vitro antioxidant activity of methanol and water extracts of Aloe vera powder was investigated using the DPPH assay. The results of the present study indicated that the dry matter was 2.65% and the water content was 97.35%. The results of antioxidant activity revealed that water extracts exhibited % inhibition (DPPH) 10.23-35.80, while methanol extracts exhibited 12.84-44.96 at concentrations of 20-100 μg/ml and was compared with standard synthetic antioxidant BHT at same concentration. IC50 (μg/ml) for the water extract was 175, and 134 for the methanol extract at 100 μg/mL. Preliminary phytochemical analysis indicated that the extract contained phenols, flavonoids, alkaloids, tannins, quinone, glycosides, carbohydrates, saponins, terpenoids, chlorophyll and proteins. The present study publicized that Aloe vera is a promising plant for phytochemicals and natural antioxidants.
