THE COMPOSITION OF ESSENTIAL OILS OF ARTEMISIA GENUS AND ARTEMISIA SECTION PLANTS GROWING WITHIN THE REPUBLIC OF BURYATIA

Abstract

The composition of essential oils of Artemisia’s section representatives was presented in this paper. Essential oils of Artemisia vulgaris L. and Artemisia selengensis Turcz. were investigated. They were obtained by hydrodistillation method from the dried aerial parts of plants. Raw materials were collected during field works in 2016. Gas chromatography-mass spectrometry (GC-MS) analyses was conducted to determine the composition of essential oil. Gas chromatography (GC) analyses was performed on an Agilent Technologies 6890 gas chromatograph equipped with quadrupole mass selective detector HP 5973 (MS) and an HP-5MS capillary column (30 m × 0.25 mm × 0.2 μm). Artemisia vulgaris L. is a perennial herbaceous plant. Camphene, neointermediol and spathulenol were the dominant components of the essential oil of Artemisia vulgaris growing within the Republic of Buryatia. Artemisia selengensis is a perennial plant which has a lignified heel of the bine. It is widely used in a traditional Chinese medicine, it has anticancer, antiobesity, and anti-inflammatory activities. The chemical composition of Artemisia selengensis species plants, growing within the territory of Buryatia, has not been studied yet. The dominant components of essential oil were monoterpenoids – 1,8-cineole, linalool, borneol, α-terpineol, terpineol-4, trans-sabinenhydrate, and sesquiterpenoids – caryophyllene oxide, copaborneol. The comparison of the composition of obtained essential oils with literature data using Principle component analysis showed that the composition of essential oils is meant to be a diagnostic indicator of Artemisia species plants only in a combination with other features of the species – morphologic and ecological.
