| Outline of Final Research Achievements |
In this study, we analyzed functional and structural features of free oligo- saccharides prepared from Zatsu mame (defined as edible beans other than soybean and peanut in Japanese) to find out good sources of latent bioactive oligosaccharides.
At first, we prepared several kinds of glycopeptides and oligosaccharide fractions from Adzuki and Tebo by a combination of cation exchange chromatography and gel filtration. Using bean glycopeptides and γ-polyglutamic acid, we developed a novel glyco-polymer bearing several hundreds of oligosaccharides and assayed stimulating activity to antigen presentation cells, T-cell proliferation, and production of cytokines. Prebiotic activities of the bean-oligosaccharides on growth of bifidobacteria and lactobacilii were determined by measuring the number of these bacteria, suggesting that Adzuki and Tebo contain prebio-active oligosaccharides or glycopeptides.
