Abstract：
BACKGROUND:Stress is a result of disturbed homeostasis and can contribute to the development of many diseases. One of the methods of combating stress is aromatherapy, which uses essential oils with a calming and relaxing effect. The aim of the work was to perform a qualitative analysis of selected essential oils with a relaxing effect. MATERIAL AND METHODS:The research concerned 6 preparations available on the Polish market, which are attributed with anti-stress activity. The qualitative analysis was carried out by gas chromatography with mass spectrometry, which allows the determination of both main and trace substances in the tested oils. The components of individual samples were compared with data from the literature. RESULTS:In the samples tested 9-36 substances were identified. The following substances had the largest share in the composition of the studied samples: limonene (0.5-91%), linalool acetate (16.8-39.2%), citronellal (0.1-28.7%), linalool (0.8-46.5%), valerianol (17.6%), geraniol (16.4%), and citronellol (14%). CONCLUSIONS:According to literature data, the main components of the studied essential oils have low acute toxicity. They can be safely used as intended and in the quantities recommended by the manufacturer. However, one should remember the potential synergistic effect (as a result of exposure to the abovementioned substances from various sources, such as: food, cosmetics, cleaning agents, etc.), as well as sensitizing effects of some compounds contained in oils. Despite the different chemical structure of active substances contained in the tested oils, it is suggested that the mechanism of the relaxing effect is identical and is associated with the inhibition of glutamatergic neurotransmission, similar to the action of benzodiazepines. Med Pr. 2019;70(2):229-47. WSTĘP:Stres jest wynikiem zaburzenia homeostazy i może być przyczyną wielu chorób. Jedną z metod walki z nim jest aromaterapia, wykorzystująca olejki eteryczne o właściwościach rozluźniających i odprężających. Celem pracy była analiza jakościowa wybranych olejków eterycznych o działaniu relaksacyjnym. MATERIAŁ I METODY:Badania dotyczyły 6 preparatów dostępnych na polskim rynku, którym przypisuje się funkcje antystresowe. Analizę jakościową przeprowadzono techniką chromatografii gazowej ze spektrometrią mas, która pozwala oznaczyć w badanych olejkach zarówno substancje główne, jak i śladowe. Składniki poszczególnych próbek porównano z danymi z piśmiennictwa. WYNIKI:W badanych próbkach zidentyfikowano 9–36 substancji. Największy udział w składzie badanych próbek mają: limonen (0,5−91%), octan linalilu (16,8−39,2%), cytronelal (0,1−28,7%), linalol (0,8−46,5%), walerianol (17,6%), geraniol (16,4%) i cytronelol (14%). WNIOSKI:Według danych z piśmiennictwa główne składniki badanych olejków eterycznych mają niską toksyczność ostrą. Mogą być zatem, w ilościach zalecanych przez producenta i zgodnie z przeznaczeniem, bezpiecznie stosowane. Należy jednak pamiętać o potencjalnym działaniu synergistycznym w wyniku narażenia na substancje z różnych źródeł (żywność, kosmetyki, środki czystości itp.), a także o właściwościach uczulających niektórych związków obecnych w olejkach. Sugeruje się, że – pomimo różnej budowy chemicznej substancji czynnych zawartych w badanych olejkach – mechanizm działania relaksacyjnego wiąże się z hamowaniem neuroprzekaźnictwa glutaminergicznego, podobnym do działania benzodiazepin. Med. Pr. 2019;70(2):229–247.
