【摘要】 采用还原糖测定仪测定熟地黄中还原糖(还原性成分)含量。结果表明,还原糖测定仪标准偏差(S)=0.14、变异系数(CV)=0.006(n=8),回收率为99.9%。同常规费林氏滴定法相比,还原糖滴定仪不受样品中颜色的干扰,而且快速、简单,精密度、准确度较高。更多还原

【Abstract】 The reducing sugar in the prepared Rhizoma Rehmannia was determined with an reducing sugar analyzer.The results show that the analyzer’s standard deviation(S) is 0.14,the coefficient of variation(CV) is 0.006(n=8),and the recovery rate is 99.9%.Compared with the conventional Fehling’s titration,the analyzer is more convenient,rapid and accurate for determination of reducing sugar with less interference of the black sample.更多还原
