Aim. To analyze the results of the quantitative content of the amount of organic acids in rhizomes with roots of Rumex confertus, rhizomes with roots of Sanguisorba officinalis, roots of Rosa majalis and roots of Rosa canina, roots of Arctium minus and roots of Arctium tomentosum, herb of Bidens tripartite by the potentiometric method, which is available in the monograph “Hibiscus” in the SPhU 2.0.
Materials and methods. The study subjects were batches of rhizomes with roots of Rumex confertus, rhizomes with roots of Sanguisorba officinalis, roots of Rosa majalis and roots of Rosa canina, roots of Arctium minus and roots of Arctium tomentosum, herb of Bidens tripartite. The quantitative content of the amount of organic acids was determined by the potentiometric method from the monograph “Hibiscus” SPhU 2.0 using a HI 2550 potentiometer of the “HANNA instruments” company (Germany).
Results and discussion. The highest content of the amount of organic acids, among the study subjects was in roots of Arctium minus (from 1.02 ± 0.04 % to 1.05 ± 0.04 %). At the same time, in roots of Arctium tomentosum this amount was almost 3 times lower (from 0.36 ± 0.01 % to 0.37 ± 0.01 %). In the batches of roots of Rosa majalis the content of this group of compounds was almost 2 times higher than in roots of Rosa canina. In rhizomes with roots of Rumex confertus and rhizomes with roots of Sanguisorba officinalis the content of the amount of organic acids differed insignificantly. In herb of Bidens tripartite the content of this group of compounds was 0.78 ± 0.03 – 0.79 ± 0.03 %. In different batches of one type of the raw material the quantitative content of the amount of organic acids varied slightly.
Conclusions. For the first time, the quantitative content of the amount of organic acids has been determined in the batches of rhizomes with roots of Rumex confertus, rhizomes with roots of Sanguisorba officinalis, roots of Rosa majalis and roots of Rosa canina, roots of Arctium minus and roots of Arctium tomentosum, herb of Bidens tripartite using the potentiometric method which is available in the monograph “Hibiscus” in the SPhU 2.0. It has been found that the highest content of the amount of organic acids is observed in roots of Arctium minus (not less than 1.02 %) and herb of Bidens tripartite (not less than 0.78 %). The results obtained will be used in further research when creating new herbal medicines with the anti-inflammatory and antimicrobial activity.
