Tanacetum vulgare L. is widespread herb in Ukraine, having a substantial resource base. The absence of national normative documentation for this type of herbal material points to the relevance of research in this area and development of modern methods for identification of phenolic compounds as a main group of biologically active substances.
Aim. Development of harmonized with European Pharmacopoeia (PhEur) requirements method for identification of phenolic compounds in Tansy flowers.
Methods. For the purpose mentioned above, a standardized TLC-method described in the State Pharmacopoeia of Ukraine (SPhU) monographs for identification of phenolic compounds in different types of herbal material was used. Validation parameters of the method for the studied herb were determined.
Results. A TLC method for identification of phenolic compounds in Tansy flowers considering modern PhEur approaches to standardization of herbs was developed. Validation of the identification method was carried out for the following validation parameters: specificity, robustness, and precision. This method was offered for implementation to the SPhU monograph «Tansy flowers».
Conclusion. TLC method for identification of phenolic compounds in Tansy flowers was developed for the first time. As a result of validation of the given method for identification of phenolic compounds, by validation parameters (specificity, robustness, and precision), following chromatography conditions were selected: Silica gel coated Aluminum-backed TLC plates, application volume for both test samples and reference samples was 10 μl, mobile phase: formic acid concentrated – water – methyl ethyl ketone – ethyl acetate (10:10:30:50 V/V/V/V), detection – spraying with solutions of aminoethyl diphenylborinate in methanol and macrogol in methanol and view under 365 nm UV. The method for quantitative determination of phenolic compounds in Tansy flowers was offered for implementation in «Tansy flowers» draft monographReferences
