Abstract
Abstract Xylan polysaccharides previously obtained from argan (Argania spinosa) leaves by sequential alkaline extractions and purified by chromatography on Sepharose CL-4B were fragmented by acid hydrolysis in 2 M HCl. The resulting fragments were separated by gel filtration on Biogel P2. The oligosaccharide fractions obtained were then characterized by gas–liquid chromatography (GLC) and matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). The results show the presence of acidic oligosaccharide motifs, some of which composed of xylose and 4-O-methylglucuronic acid and other ones comprising rhamnose and galacturonic acid.
