Abstract
Study on ultrasonic-solvent assisted extraction technology of soluble polysaccharuie from pine nut shell. Through single factor test and orthogonal experiment L9 ( 34 ) optimize extraction process. The removal efficiency of pine nut shell polysaccharide on hydroxyl radicals (OH · ) and superoxide anion (O2- · ) detected was investigated through removal experiment. The result demonstrate that the ultrasonic-assisted extraction optimum technological conditions as follows: ultrasonic time 30. 0 min, extraction temperature 60 ℃, solid-liquid ratio 1 : 50(m : V) , and ultrasonic extraction times 1; the pine nut shell polysaccharides have a strong scavenging capacity effect on hydroxyl radicals(OH · ) ,but a general scavenging capacity effect on superoxide anion (O2- · ).关键词
