摘    要:为选出一种比较准确、方便的测定真菌多糖的方法,以桦褐孔茵茵丝体发酵液提取的粗多糖为原料,对苯酚一硫酸法、蒽酮-比色法、斐林滴定法3种方法进行比较.3种方法比较而言,苯酚-硫酸法与蒽酮-比色法测得的糖含量相差甚微,分别为61.07%、62.25%.苯酚-硫酸法显色不稳定,蒽酮-比色法比较容易操作,测定的多糖含量和回收率均最高,回收率为125%;斐林滴定法回收率较低45%,测得的多糖含量偏低为33.12%,最终确定蒽酮-比色法为最佳测定方法.

关 键 词:桦褐孔菌  苯酚-硫酸法  蒽酮-比色法  斐林滴定法  多糖含量

Abstract:In order to select an accurate, convenient method of fungi polysaccharide determination, the methods of Anthrone-sulfuric method, phenol-sulfuric method and direct-titration method were compared. The results showed: Among the three methods, there were not many differences between Phenol-sulfuric method and Anthrone-sulfuric method,contents of the polysaccharide were 61.07 %,62.25 %. Phenol-sulfuric method showed color development was not very steady while Anthrone-sulfuric method was easier to operate. Anth...
Keywords:Phaeoporus obliquus  phenol-sulfuric method  anthrone-sulfuric method  direct-titration method  polysaccharide content
