Synthesis and Physiochemical Properties of Sulphated Tamarind (<i>Tamarindus indica</i> L.) Seed Polysaccharide.

ABSTRACT: Tamarind seed polysaccharide (TSP) is a neutral water-soluble galactoxyloglucan isolated from the seed kernel of Tamarindus indica with average molecular weight (Mw) 600-800 kDa. The high viscosity of TSP slows solubilisation, and the absence of charged substituent hinders the formation of electrostatic interactions with biomolecules. TSP was sulphated in a one-step process using dimethylformamide as a solvent, and sulphur trioxide-pyridine complex as a sulphating reagent. Studies of chemical structure, molecular weight distribution and viscosity were conducted to characterise the synthesised products. The sulphation degree was established by conductimetric titration; the sulphate group distribution was studied by NMR spectroscopy and liquid chromatography-mass spectrometry, and sul
