Buckwheat sprout is widely consumed as a potential functional and healthy vegetable. Although buckwheat abundant in soluble dietary fibers (SDFs), the information about their structural properties biological functions remains unclear, which largely limits applications foods. Therefore, to promote rational usage of SDFs from sprouts food industry, physicochemical were investigated. Results revealed that rich (41.2–43.3, mg/g). isolated both common Tartary possessed similar chemical structures, mainly consisting rhamnogalacturonan-I with arabinan arabinogalactan side chains. However, molecular masses different, ranged 2.526 × 105 (common buckwheat) 17.781 Da (Tartary buckwheat). In addition, presence large number pectic-polysaccharides may contribute remarkable vitro beneficial effects SDFs, such antioxidant, antiglycation, anti-cancer effects. These findings can be conducive better understanding sprouts, laying foundation for ingredients.
