甘草残渣中多糖的分离纯化及性质分析
ISOLATION, PURIFICATION AND ANALYSIS OF A POLYSACCHARIDE FROM RESIDUES OF GLYCYRRHIZA URALENSIS FISCH
【摘要】 甘草残渣经水浸提、去色素、除蛋白、透析、DEAE-Cellulose(DE-32)和SephadexG-75凝胶柱层析得到纯的水溶性物质(GPS),DNS法检测和IR分析证实,GPS为多糖类物质,比旋度[α]15D+125°(c0.1,H2O),经纸层析(PC)、元素分析、IR测定、13CNMR分析,确定其基本结构为α-(1,4)键连接的单一葡聚糖.
【Abstract】 The polysaccharide (GPS) was isolated and purified from residues of Glycyrrhiza uralensis Fisch by water extraction, pigment and protein removal, dialysis, ion exchange chromatography on DEAE cellulose (DE 32) and gel filtration (Sephadex G 75). Optical rotation of GPS is [α] 15 D+125°(c0.1,H 2O).Paper chromatography (PC), elemented analysis, infrared spectrum (IR) and 13 CNMR showed that GPS is a α (1,4) linked glucan.
