Improved in vitro antioxidant and antimicrobial capacities of polysaccharides isolated from Salicornia arabica.

A newly profiling of Salicornia arabica (SAPS) polysaccharides was investigated. The water-soluble polysaccharide extract extracted from the Tunisian halophyte (SA) contained sulfate (9.64 ±â€¯0.003%), carbohydrate (86.33 ±â€¯0.003%), protein (1.24%), and uronic acids (3.33 ±â€¯0.37%). The analysis of the monosaccharide composition revealed the presence of arabinose, Glucopyranose galactose, Glucuronic acid and glucose. The identified polysaccharide was considered as heterogeneous and highly branched via gaz chromatography, Fourier Transform Infrared Spectrometer (FT-IR), Thin layer chromatography (TLC) analysis. It also displayed an important radical scavenging and reducer power as well it exhibited effective antimicrobial properties.
