Abstract

Buckwheat (F. tartaricum Gaertn) has many functions of dietotherapy and health care, which are beneficial to the treatment of diabetes, hypertension, cardiovascular disease, anti-cancer and so on. Buckwheat polysaccharide is one of important functional ingredients of Buckwheat. In this paper, the extracting technologies of polysaccharide from Tartary buckwheat were investigated. The results showed that the optimum parameters for the extraction is solid to liquid ratio 1:20, temperature 85?, duration 120min, extraction for 2 times, alcohol concentration 80%.
