Comparative Assessment of Antioxidant Activity and Phytochemical Analysis of Plants Peels Belongs to Rutaceae Family Using Different Extraction Techniques

Abstract

This study was designed to evaluate the antioxidant activity of three plants peels of Rutaceae family. The extraction was done by individual cold percolation (Petroleum ether, acetone, methanol, aqueous), Infusion, maceration (methanolic & ethanolic), decoction, ultrasonication and microwave assistant extraction methods. The antioxidant activity was evaluated using antioxidant assay, 2,2-diphenyl-1-picryl hydrazyl free radical scavenging assay. Total phenol and flavonoid content was also measured. The varied level of radical scavenging activity was observed in different extracts. This suggests that significantly influences the choice of solvent and methods for extraction. This study demonstrated that peels of all plants, could serve as good source of antioxidants for use in the preparation of dietary supplements or nutraceuticals, food ingredients, pharmaceutical, and cosmetic products.
