Comparison of chemical composition of selected essential oils used in respiratory diseases

摘要

Background: Essential oils are fragrances extracted from plants. They have a smooth consistency and pleasant smell. Essential oils havebeen applied in aromatherapy, cosmetics, food and pharmaceutical products. The aim of the study was to analyze the composition ofselected essential oils used in respiratory diseases. Material and Methods: The qualitative analysis was performed by gas chromatographywith mass spectrometry. For the study 6 essential oils available in Polish shops and used in various respiratory diseases were chosen.The results were compared with the information provided by the manufacturer and the literature. Results: The method used in the presentedwork allowed to qualitatively identify the main components in studied essential oils. In the analyzed samples generally occurred:α- i β-pinene, limonene, terpinen-4-ol and caryophyllene. In addition to limonene, the presence of linalool, eugonol and geraniol, potentiallyallergenic substances, were also detected. Conclusions: The qualitative composition of the studied essential oils comply withthe existing literature data. Their main ingredients show antimicrobial and antiviral activities, therefore they are used to eradicate thesymptoms of infection. However, the attention should be paid to the composition of the products because they often comprise potentialallergens. Information on the presence of such a substance in the preparation should be clearly marked by the manufacturer on thepackaging. Fragrances are also found in a number of household products that increase their concentration in the air of living premises,thereby increasing the risk of side effects especially in people with allergies or sensitive.
