Extraction Process, Structural Characteristics And Biological Activity Of Mesona Chinensis Polysaccharide, Dong Wei, Ma Sheng-Jian, Guo Jun-Xian, Luo Hao, Tao Mei-Hua

Food and Machinery

Objective: This study focused on improving the extraction rate and application of Mesona chinensis polysaccharide (MCP). Methods: MCP was obtained from fresh M. chinensis by thermally alkaline extraction, protein removal by trichloroacetic acid and purification by dialysis bag. The chemical structure was analyzed by ultraviolet and infrared spectrum scanning, X-ray diffraction and SEM scanning. The antioxidant activity was determined by in vitro antioxidant capacity, and the antibacterial activity was determined by antibacterial experiment. Results: The optimal extraction conditions of MCP were solid-liquid ratio of 1∶5.47 (g/mL), soaking time of 10.71 min, sodium bicarbonate concentration of 1.64%. Under …
