从淡肤根石耳和网脊石耳提取了多糖,并应用分光光度法进行多糖含量测定。经蒽酮-硫酸显色,波长615nm处测定其多糖含量分别为网脊石耳为13.71%,淡肤根石耳为11.52%,研究结果表明蒽酮硫酸法简便,样品溶液显色稳定,重复性好,仪器精密度良好,平均回收率分别为网脊石耳为98.35%,RSD=1.35%(n=3),淡肤根石耳为99.32%,RSD=1.97%(n=3)。 Polysaccharides were extracted from the eyedrops of the eyedrops and the emeralds, and polysaccharide content was determined by spectrophotometry. The anthrone-sulfuric acid color, the wavelength of 615nm at the polysaccharide content of the mesh stone ear were 13.71%, light skin root fungus was 11.52%, the results show that anthrone sulfuric acid method is simple, the sample solution color stability, repeatability The average recovery was 98.35% for net ridge ridges, RSD = 1.35% (n = 3), pale edible root ear was 99.32%, and RSD was 1.97% (n = 3).
