雀石蕊经三氯甲烷抽提除去色素，用热水提取，乙醇沉淀，经重结晶微晶纤维素柱层析纯化，得CLS多糖。经SephadexG－150层析为均一性多糖，糖的含量为81．2％。气相色谱检测由鼠李糖（Rha）、阿拉伯糖（Ara）、木糖（Xyl）、甘露糖（Man）、葡萄糖（Glc）和半乳糖（Gal）组成，摩尔比为1∶0．71∶0．45∶4．68∶9．94∶3．64，平均分子量为1．3×106。经高碘酸氧化，Smith降解主要由1→2和1→6甙键连结而成的杂多糖。红外光谱分析具有多糖的特征吸收。
Lucidum was extracted with chloroform and removed pigment, extracted with hot water, precipitated with ethanol and purified by recrystallization microcrystalline cellulose column chromatography to obtain CLS polysaccharide. Sephadex G-150 chromatography is a homogeneous polysaccharide with a sugar content of 81.2%. The gas chromatographic analysis consisted of rham, arabinose, xylose, mannose, glucose, and galactose (Gal) at a molar ratio of 1:0.71: 0.45:4.68:9.94:3.64, the average molecular weight was 1.3 x 106. By periodate oxidation, Smith degrades heteropolysaccharides mainly composed of 1→2 and 1→6 bonds. Infrared spectroscopy has characteristic absorption of polysaccharides.
