Phytochemical investigation, antioxidant, anti-inflammatory and cytotoxic activities of Tunisian medicinal .

The current study aimed to evaluate Tunisian Tamarix africana Poir biological activities. In this study, novel biological activities of the shoot extracts related to their phenolics investigated. Secondary metabolite contents, antioxidant, anti-inflammatory and cytotoxic activities of four extracts (hexane, dichloromethane, methanol and water) were investigated.

New Sulphated Flavonoids from Tamarix africana and Biological Activities of Its Polar Extract.

The phytochemical investigation of Tamarix africana Poir. (Tamaricaceae) shoot polar extract afforded three new sulphated flavonoids, (2,4)-5,7,4'-trihydroxyflavan-4-ol 5,7-disulphate (), (2)-5,7,4'-trihydroxyflavan 7--sulphate (), and (2)-naringenin 4'--sulphate (), together with ten known compounds. Their structures were determined by spectroscopic methods including 1D and 2D NMR analysis and HRMS.

Antioxidant, anti-inflammatory and anticancer activities of the medicinal halophyte Reaumuria vermiculata.

Reaumuria vermiculata is a xero-halophytic specie widely distributed in the south of Tunisia. In the current study, antioxidant, anti-inflammatory and anticancer activities of Reaumuria vermiculata shoot extracts as well as its phenolic compounds were investigated in different solvent extracts (hexane, dichloromethane, methanol and water). Results showed a strong antioxidant activity, using the ORAC method and a cell based-assay, in methanol extract as well as an important phenolic composition (117.
