Component composition of extracts 14 medicinal materials kinds was study by gas chromatography with mass-spectrometric detection for revealing of the marker compounds specific for particular plant species. Extraction of components from the investigated objects was carried out by extraction of dry ground raw material with ethanol. For the analysis of polar compounds, the extracts were further derivatized to give the corresponding trimethylsilyl derivatives. Identification of components was carried out using commercial (NIST11, Wiley14) and own custom mass-spectrometer libraries. A number of compounds with species specificity were found for Schisandra chinensis, Ginkgo biloba, Oplopanax elatus, Oplopanax horridus, Ferula soongarica, Epimedium brevicornu, Epimedium koreanu, Cnidium Monnieri, Tribulus terrestris. The possibility of practical application of identified marker compounds for establishing the authenticity and quality control of multicomponent plant gathering and biologically active food additives on the example of the analysis BAA «Vertera Endo mix», «REDTEST», «Devil’s Club» is shown. Based on the analysis of extracts Panax ginseng, Aralia mandshurica, Rhodiola rosea, Eurycoma longifolia and Eleutherococcus senticosus, it was not possible to identify marker compounds
