Phytochemicals, antioxidant and antimicrobial potentials and LC-MS analysis of hydroalcoholic extracts of leaves and flowers of Erodium glaucophyllum collected from Tunisian Sahara

Abstract Erodium glaucophyllum collected from Tunisian Sahara was never presented in the relevant literature yet. In this study, the phytochemical profiles, chemical compositions, antioxidant and antimicrobial activities, and Kill-time assay of the hydroalcoholic extract of flowers and leaves were investigated. The highest content in phenols, flavonoids and tannins was shown in flowers extract (350 ± 5 mg GAE/g, 34 ± 1 mg QE/g and 221.8 ± 0.0 mg β-carotene E/g, respectively). The carotenoids amount in leaves was about 6-fold higher than it’s in flowers. Conducted LC/MS analysis revealed ...
