The paper presents the results of a comparative analysis of the component composition of alcoholic extracts of particles of Calendula officinalis L. decorative Neon mark: stalks, roots, leaves, flowers, etc., by gas chromatography/mass spectrometry. As a result of the study, more than 30 biologically active compounds (BAС) were identified that belong to different classes of organic compounds (including sesquiterpens, hydrocarbons, fatty acids and their ethyl esters, phytosterols). Their relative quantitative assessment was calculated by the method of internal normalization. It was found that the mass yield of extractable substances depends on the part of the plant used: the maximum (about 10%) from the petals and flowers, the minimum (less than 1%) from the roots. It has been established that the detected BAC is contained in all parts of the plant, but their content varies greatly: the most enriched are petals and flowers, the least - the stems, leaves, roots. Vitamin E is found only in flowers, flower petals and calyxes. The presence of a large number of phytosteros in Calendula officinalis L. is of interest for further pharmacognostic studies of this plant.
