Abstract :

This study discusses and shows as to determine the degree of polymerization (DP) of inulin, exemplified by samples obtained from roots of Brazilian medicinal plants as Stevia rebaudiana and Pfaffia glomerata, using different analytical methodologies as colorimetric methods, gel permeation chromatography coupled to multiangle laser light scattering and refractive index detectors (GPC/MALLS), nuclear magnetic resonance (NMR), gas chromatography coupled mass spectrometry (GC/MS), electron spray ionization mass spectrometry (ESI/MS) and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDITOF MS). It will be shown that these techniques and others can be used together to give complementary information thus providing a more accurate estimate of the overall DP of the inulin like molecules.
