Abstract:
UMH polysaccharide was isolated and purified with alcohol precipitation from hot water extract of Umbilicaria hypococcinea Liano. By Sephadex G-150 column chromatography, UMH was shown to be a single homogeneous substance, sugar content 90.4%. By gas chromatogra phy analysis, UMH was composed of glucose, mannose and glucuronic aeid, their molecule ratio was about 45:1:9. Its mean molecular weight was estimated to be 40?104. IR analysis Periodate oxidation and Smith degradation showed that the main chain of UMH is composed,of ?(1→6) and (1→4) linkage, and was an acidic hetrosaccharide.
