(a) Effects of purified oligosaccharides and 1 mg/mL of fructo-oligosaccharide (FOS) on the viability of RAW264.7 murine macrophages (5 × 104 cells/well). (b) Effects of the purified oligosaccharides on NO production in RAW264.7 murine macrophages (5 × 105 cells/well). Data are presented as means ± standard deviation of three independent experiments. * p < 0.05, ** p < 0.01, and *** p < 0.001 vs. non-treated oligosaccharides.
