QUANTITATIVE DETERMINATION OF TANNINS IN SOOTHING PREPARATION №2
The aim of the study was quantification of tannins in the composition of soothing preparation №2 using spectrophotometry techniques and permanganometry and comparative assessment of their effectiveness. As the materialwe used soothing preparation №2, prepared according to the standard recipe at the Department. We used the standard method of titration proposed by the State Pharmacopoeia XIII ed., as well as pharmacopoeial method of spectrophotometric titration, modified by several authors. As a result, we determined the quantitative content of tannins in the soothing preparation №2 by two methods. This allowed to compare the results, and propose a method of spectrophotometric determination of tannins as the most preferred, because of the accuracy of the results.
