【 摘 要 】

Burdock Fructooligosaccharide (BFO) were acetylated using acetic anhydride. The maximal degree of acetylation (DSAC) was 2.15, which was obtained by varying the reaction factors such molar ratio of acetic anhydride to fructofuranose unit (FU). The FT-IR,1H NMR and13C NMR spectra showed the introduction of acetylate group, and the reaction occurred at C-6, C-4 and C-3 in the fructofuranose unit of BFO. The molecular weight estimated by HPGPC were 5527.9-6816 g/mol for A-BFO (DSAC=1.0).
