茶枝柑皮多糖的分离纯化及单糖组成分析
Isolation,Purification and Monosaccharide Composition Analysis of Citus reticulata Peel Polysaccharides
摘要
Abstract
Polysaccharides were extracted from dried powder of Citus reticulata peel with acidic water,followed by pigment removal on D-201 ion exchange resin,protein removal by Sevag,s method,dialysis and freeze-drying.The CPA-I fraction was achieved by sequential column chromatographies on DEAE-sepharose fast flow and Sephadex G-100.Monosaccharide composition analysis of CPA-I was carried out by HPLC based on pre-column derivatization with 1-phenyl-3-methy1-5-pyrazolone(PMP).High performance size exclusion chromatography(HPSEC) was used for purity analysis and relative molecular weight determination.UV-visible and infrared(IR) spectral analyses were conducted for structural characterization.The results showed that the molecular weight of CPA-I with high purity was 7.96×104,and the monosaccharide composition of the polysaccharide was composed of galacturonic acid and arabinose.The IR spectrum indicated that CPA-I was a galacturonic acid polysaccharide esterified by carboxylic acid.关键词
