摘要
在选定高效液相色谱操作条件下,研究了使用没食子酸作为标准测定焦性没食子酸含量的方法,对两者的浓度比值与其色谱响应值比值的关系进行了回归分析,方法标准偏差0.059,变异系数0.036,线性相关系数0.9999,回收率101.2%。
A simple but effective HPLC method for the quantitative determination of pyrogallol using gallic acid as internal standard was explored.A regression model was established between the peak area ratio and the concentration ratio of pyrogallol and gallic acid.The results showed that the proposed method could accurately determine pyrogallol content.The standard deviation,coefficient of variation,recovery and linear relative coefficient were 0.059,0.036%,101.2% and 0.999 9,respectively.
