Abstract: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.
Key words:pyrogallol;gallic acid;HPLC;quantitative determination
