Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>Sulfated derivatives of polysaccharide from Momordica charantia L. (MCPS) with different degree of sulfation (DS) were synthesized by chlorosulfonic acid method with ionic liquids as solvent. Fourier transform infrared spectra and ¹³C nuclear magnetic resonance spectra indicated that C‐6 substitution was predominant in MCPS compared with the C‐2 position. Compared with the native polysaccharide from Momordica charantia L. (MCP), MCPS exhibited more excellent antioxidant activities in vitro, which indicated that sulfated modification could enhance antioxidant activities of MCP. Furthermore, high DS and moderate molecular weight could improve the antioxidant activities of polysaccharide. © 2013 Wiley Periodicals, Inc. Biopolymers 101: 210–215, 2014.</p> </abstract>
