Chemical profiling of maceration and decoction of Tamarix gallica L. organs and in vitro biological properties

ABSTRACTTamarix gallica L. is a halophytic medicinal shrub traditionally used in the treatment of liver disorders. Leaf and flower infusions are widely used for anti-diarrheic and anti-inflammatory preparations. In this work, we have explored the combined effect of method (Maceration and Decoction) and solvent extraction (70% Methanol, 70% Ethanol, 70% Acetone, and Water) on phenolic composition and biological activities (antioxidant and anti-inflammatory) of different T. gallica organ extracts (Leaves, Flowers, Stems, and Fruits). Obtained results showed that Tamarix leaves reveal more potent antioxidant activity. Methanol (70%) was the best maceration solvent for the extraction of leaves and flowers with high total antioxidant and anti-radical capacities. HPLC analysis showed that catechin, isorhamnetin-3-O-glucoside, isoquercetin were the major phenolics in 70% methanolic extract. Furthermore, this extract showed considerable anti-inflammatory activity. This prospect could be of great importance in the valuation of this halophyte as a source of natural antioxidants and anti-inflammatory drugs.KEYWORDS: Tamarix gallica L.phenolic compoundsantioxidant activityanti-inflammatory activity Disclosure statementNo potential conflict of interest was reported by the author(s).Supplementary materialSupplemental data for this article can be accessed online at https://doi.org/10.1080/09603123.2023.2256679Additional informationFundingThis work was supported by the Tunisian Ministry of Higher Education and Scientific Research (LR19CBBC06).
