The Effect of Solvents and Extraction Procedure on the Recovery of Phenolic Compounds and the Antioxidant Capacity of Algerian Bassia Muricata L. Extracts

Abstract

This paper focuses on the study of the effect of extraction solvent choice on phenolic compounds contents and antioxidant activity of Bassia muricata. In this study, five different solvents namely: water, acetone, ethanol, methanol and hexane, and three extraction techniques were used to extract phenolic compounds: microwave-assisted extraction, Soxhlet and maceration. Total phenolics, total flavonoids and condensed tannins contents were determined. The results showed that different solvents with different polarity had a major effect on polyphenolic contents and antioxidant activity. Microwave-assisted extraction was the best suited for the extraction of antioxidant molecules when compared to Soxhlet and maceration.
