Water-soluble polysaccharides were extracted sequentially from Retama raetam. Dried AlcoholInsoluble Residues (AIR) ofRetama raetam were treated sequentially with deionised water, ammonium oxalate
and basic solutions and purified by ultrafiltration. The resulting pectin extracts analysed for some physicochemical parameters. The results show that pectin yield (62% dry AIR), uronic acid (260-640 mg g^-1),
neutral sugars (320-540 mg g^-1), degree of methylation (20-31%) aud acetylation (2-19%), molar mass (8. 93x 10^4-3.42x 10^5 g mol^-1) and intrinsic viscosity (27- 47 mL g^-1) varied with the various extraction methods used. Extraction with ammonium oxalate solution gave the highest pectin yield, with high molar mass and degree of methylation.
