Abstract

The essential oils were obtained from Achillea carpatica Błocki ex Dubovik grass and Echinacea pallida’s (Nutt.) Nutt. roots by method of hydrodistillation. The quantitative content of the essential oil in A. carpatica grass was about 0.2%; in E. pallida (Nutt.) Nutt. roots – 0.7%. The chemical composition was determined by GC/MS analysis, performed on Hewlett-Packard gas chromatograph HP-6890 with mass-selective detector HP-5972. Identification of individual compounds was made by comparison of their mass spectra with their internal reference mass spectra electronic libraries Nist 02 and Wiley 138k. 41 compounds of Achillea carpatica Błocki ex Dubovik grass essential oil and 17 substances of Echinacea pallida’s (Nutt.) Nutt. roots have been identified.
