Abstract
Objective To study the memberane separation technology of preparating polysaccharide of Pinus koraiensis corns .Methods Microfiltration (MF) and ultrafiltration (UF) was used to preparate polysaccharide of Pinus koraiensis corns .Effects of concentration ,temperature ,pressure of feed on exudate flux of MF was studied ,and the best condition was found by orthogonal test . Membrane ,molecular cut off was 100 ,50 ,10 and 6kDa ,was used to separated polysaccharide of Pinus koraiensis corns .Results The best condition of MF was 25g/L ,40 ℃ ,0 .10 MPa .Ultrafil-tration purified polysaccharide content increased from 7 .20% to 35 .16% .The pine cone polysac-charide molecular weight distribution ,the results are as follows :Polysaccharide with molecular weight >100 kDa content accounting for 9 .50% ,50-100 kDa content accounting for 70 .20% ,10-50 kDa content accounting for 3 .20% .6-10 kDa content accounting for 17 .1% ,Conclusion Mem-brane separation technology can be used to preparate and purify polysaccharide of Pinus koraien-sis corns .关键词
