Immunostimulatory activity of soybean hull polysaccharide on macrophages.

ABSTRACT: Water-soluble polysaccharide isolated from soybean hull and fractionated using ion-exchange chromatography were investigated to determine their molecular characteristics and immunostimulating activity. In the present study, soybean hull polysaccharide (SHP) was separated and purified to obtain three main fractions (F1, F2 and F3), and their chemical and monosaccharide compositions were analyzed. SHP was mainly composed of carbohydrates (64.3%), proteins (16.2%) and sulfates (12.5%), with minor levels of uronic acid (3.2%), and predominantly contained glucose and mannose as monosaccharides. Moreover, when compared with cells treated with RPMI medium, SHP was revealed to promote the proliferation and pinocytosis of RAW264.7 cells, and to enhance the production of nitric oxide (NO), tumor nec
