The Melaleuca plant genus is included in the myrtle family and is found from the Indochina Peninsula to Tasmania. The greatest diversity of plants in this family is found mainly in Australia. Essential oils extracted from plants of the Melaleuca genus are a mixture of valuable chemicals that exhibit a broad spectrum of biological properties. Studying the chemical composition of these oils can provide information on their active ingredients, which has applicationsin the pharmaceutical and cosmetic industries, as well as in aromatherapy. The essence of the study was to conduct an analysis to determine the chemical composition, learn about the main volatile compounds, as well as their percentage content in essential oils extracted from different varieties, namely: Melaleuca alternifolia (TTO), Melaleuca viridiflora (niaouli oil) and Melaleuca cajuputi (cayeput oil). Methods of analysis included gas chromatography coupled with mass spectrometry (GC-MS) to identify and determine the chemical components present in the samples. Two different chromatographic columns were used in the study - a non-polar column and a polar column. The results of the analysis indicated the presence of a variety of chemical components in essential oils of the Melaleuca genus. The composition of the chemical compounds present varied depending on the column used for analysis and the type of plant from which the oil was extracted. The main components of niauli and cayeput oils are: 1,8-cineole (eucalyptol), α-terpineol and α-pinene. TTO, on the other hand, contains terpinene-4-ol, p-cymene and γ-terpinene. These compounds exhibit antibacterial, anti-inflammatory activity.

Zasadność stosowania leków roślinnych w chorobach układu oddechowego wynika z tradycji i w wielu przypadkach dobrze udokumentowanego działania. W niniejszej pracy zaprezentowano ich podział na leki hamujące odruch kaszlowy, działające do nich przeciwnie, tzn. wykrztuśnie, przedstawiono także surowce o silnym działaniu przeciwbakteryjnym i takie, które powodują efekt spazmolityczny w mięśniach gładkich dróg oddechowych.

The relevance of herbal medicine in respiratory system diseases is a result of the traditional use and, in many cases, well-documented activity of plant raw materials. In the present work the pertinent medicaments are divided into the drugs inhibiting cough and the ones with the opposite, that is expectorant activity. There are also presented raw materials of strong antibacterial activity and those inducing spasmodic effect on the smooth muscles of the respiratory tract.
