Introduction. One of the promising directions in the intensively developing pharmaceutical industry is the study of wild plants closely related to pharmacopoeial species in order to expand the raw material base of medicinal plants. In this aspect, the genus Artemisia L., which is one of the numerous species in the family Asteraceae, is of interest. There are about 800 species of Artemisia in the world flora. Plants of the genus Artemisia L. contain secondary metabolites of various chemical structures, of which phenolic compounds are one of the leading groups. In the Saratov region plants of this genus are poorly studied in terms of chemical composition.
Objective: comparative study of chromatographic profile of extracts of above-ground parts of non-pharmacopoeial Artemisia species growing in Saratov region.
Material and methods. The objects of the study were samples of herbs of A. austriaca Jacq., A. marschalliana Spreng., A. santonica L., А. dracunculus L. collected in 2021 in the Saratov region during the period of mass flowering. Thin-layer chromatography of the extracts was carried out in the solvent system: ethyl acetate – anhydrous methanoic acid – purified water (40:4:6). The adsorption zones were detected by UV light after sequential treatment with 1% solution of diphenylboronic acid aminoethyl ether alcoholic solution and 5% solution of macrogol 400 alcoholic solution.
Results. Chromatographic profiles of extracts of four species of Artemisia growing in the Saratov region were obtained. The study revealed both similarities and differences in the values of retention factors, colouring, intensity of adsorption zones of the tested extracts.
Conclusion. The experimental data obtained represent practical interest in establishing the authenticity of these wormwood species, as well as in standardisation of pharmaceutical phytosubstances based on them.
