ABSTRACT
The 13C and the 1H of nuclear magnetic resonance spectroscopy of heparin were studied in research. Interpretation of the spectra of the standard and test samples shows obvious similarities in the peaks at various spectra. These spectra numbers are at peak 1.976 and 1.847 ppm representing N-acetyl group in the N-glucosamine resonance 2.0 and 2.3 ppm, and the test sample and the standard showing doublet peaks at 4.700 ppm, Heparin depict a peak at 5.363 and 5.141ppm, of the glucuronic acid and the N-acetylglucosamin. The additives and the halogenated groups are observed in the test sample (figure 4.2) at 6.872,8.862, 8.546, 8.536 and 8.168, 7.463, 7.548 ppm respectively theses peaks were observed to be absent in the standard. there is a quadruplet observed in the region of 3.212 to 4.269 of both the test sample and the standard. These spectra are responsible for the characterization of heparin using nuclear magnetic resonance spectroscopy.
