Abstract
Plants of the genus Mentha sp. have been used by humans for centuries. Currently, they are used in various industries. Due to the characteristic composition of the essential oil of each species, different species can be used for specific needs. Mint samples were collected near the village of Dziesławice on a wet meadow near a watercourse. Initially, the plant was identified as Mentha aquatica L. Profiling of organic volatile compounds was performed with the use of a gas chromatograph coupled with a mass spectrometer with using solid-phase micro extraction (SPME) technique. The largest amounts of piperitone oxide were identified (74.66%), α-farnesene (4.48%), γ-amorphene (3.18%). The occurrence of piperitone oxide was confirmed using the 13 C NMR technique. Isomer identification was performed using a polarimeter, identifying it as a cis compound. Publications indicate the presence of piperitone oxide in Mentha aquatica L. up to 25%, and sometimes it is unidentifiable. Mentha suaveolens Ehrh has the most similar chemical composition to the analyzed mint. It contains piperitone oxide in the range of 80%-25% and its composition of organic volatile compounds is similar. However, morphologically it looks different. To sum up, our research indicates the identification of Mentha sp., which contains over 74% cis-piperitone oxide. It may be a new chemotype of Mentha aquatica L. or morphologically changed Mentha suaveolens Ehrh. Another explanation may be the influence of the specific environment and season in which the mint samples were collected or the identification of a new hybrid.
