Abstract

In this study, sulfated derivatives of xanthan gum (XG) were synthesized and then characterized using FTIR, 1H NMR, 13C NMR, GPC, DSC, TGA, SEM, HPLC, Zeta (ζ) potential and elemental analysis. The degrees of substitution (DS) was 0.51 (SXG-1) and 1.23 (SXG-2). From the NMR spectrum and methylation analysis by GC–MS, it was concluded that the sulfate groups had completely introduced into the C-6 hydroxyl groups. The native XG and SXGs were further evaluated for their anticoagulant, antithrombotic and cytotoxic activities. The results suggest that the SXG-2 could be used as a promising anticoagulant and antithrombotic agent for clinical applications.
