| Abstract: | APS-2 is a non-starch polysaccharides with white and flocculent appearance,in which the contents of neutral sugar,uronic acid and protein were 66.8%,9.3% and 8.4%,respectively. The associated protein portions in APS-2 consisted of 13 different amino acids. To their monosaccharide composition,APS-2 consisted primarily of Ara(55.0mol%),Gal(26.1mol%),and Glc(11.3mol%),accompanied by some Man(5.7mol%)and Rha(1.9mol%)which were tested by FT-IR and GC. |
