摘 要 ：红石耳用热水提取，乙醇沉淀，精制得ＵＭＨ多糖，经ＳｅｐｈａｄｅｘＧ─１５０柱层析证明为─组均一性多糖。气相色谱检测由葡萄糖、甘露糖、葡萄糖醛酸组成，克分子比为４５：１：９，是一组酸性杂多糖。

Abstract:UMH Polysaccharide has been obtained fron Umbilicaria hypococcinea Llano. By sephadex G-150 column chromatography, UMH was shown to be single substance. By G. C.analysis was composed of glucose mannose and glucuronic acid, molecule ratio was about 45:1:9.
