On the other side, we performed the 1D and 2D - NMR analysis as complementary information to the other techniques in the present work. Such analysis was performed to try to replace the traditional acid hydrolysis, methylation/acetylation and GC-MS used in glycoside analysis. On the opposite to NMR, we do not have access to this analysis, and we could not find it as a service.
According to the 1H NMR spectrum, it can be assumed that EPS has a complex branched structure.
