Název v původním jazyce

Spectroscopic estimation of feruloyl groups in sugar beet pulp and pectin

Popis výsledku v původním jazyce

Ferulic (4-hydroxy-3-methoxycinnamic) acid is an important biologically active phenolic compound. It is a widespread component of plant cell walls and present in plant polysaccharides isolated from cell wall raw materials. Ferulic acid can form dimers through oxidative cross-linking and, therefore, take part in integration of polysaccharides, lignin and protein into the mesh-like network of the cell wall. Feruloyl groups (FG) are covalently linked by ester bound to neutral sugar side chains of sugar beet pectin. Spectroscopic estimation of FG in sugar beet pulp and pectin is described. UV-Vis absorption, Vis-NIR, FT-IR and FT-Raman spectra of the samples of sugar beet pulp and pectin were measured and the specific bands assigned to FG were used in quantification. According to all described methods, FG content was 0.1-0.4 % in sugar beet pulps and 0.6-2.0 % in sugar beet pectins. The results of presented spectroscopic methods were in good agreement with the conventional HPLC method. The
