title: Extraction, chemical analysis of Angelica sinensis polysaccharides and antioxidant activity of the polysaccharides in ischemia-reperfusion rats.
abstract: Angelica sinensis polysaccharides were analyzed using high performance liquid chromatography (HPLC) and Fourier Transform Infrared (FT-IR). The major sugar of the polysaccharide was saccharose (18.55%); and the sugar constituted about 83% of the monomer content. Glucose and fructose were found as minor components of the polysaccharides. The FT-IR spectra of A. sinensis polysaccharides are used for determination of their structural features. The FT-IR spectrum of A. sinensis polysaccharides showed bands at 1641 cm(-1), 1415 cm(-1), 1050 cm(-1) and 926 cm(-1) characteristic for the carboxylic group. Absorptions at 2920-2930 cm(-1) are attributed to asymmetrical stretching vibration of CH(2)-group. Medium stretch observed in the range 1650-1400 cm(-1) is assigned to C-C stretching of polysaccharides. Cardioprotective effects of A. sinensis polysaccharides were evaluated by using myocardial ischemia/reperfusion (IR) rats. A. sinensis polysaccharides treatment significantly reduced myocardial infarction size, enhanced CT-1 and antioxidant enzymes activity, downregulated caspase-12 mRNA expression in rats. The study strongly suggests the cardioprotective activity of A. sinensis polysaccharides in limiting ischemia-reperfusion induced myocardial injury.
