Abstract
Essential oils of aromatic and medicinal plants generally have a diverse range of activities because they possess many active constituents that work through a several modes of action. Artemisia, the largest genus of the family Asteraceae, has a number of effects against human and plant diseases. The main purpose of the present study was to investigate chemical compositions of essential oils of two Artemisia species, Artemisia palustris L and Artemisia sericea Weber ex Stechm from the Mongolian steppe zone using gas chromatography and gas chromatography-mass spectrometry. The essential oil of A.palustris was characterized by the presence of monoterpene hydrocarbons such as trans-β-ocimene (59.1%), cis-β-ocimene (11.6%) and myrcene (7.1%), while the oil of A.sericea was dominated by the presence of three oxygenated monoterpenoids as 1,8-cineole (25.8%), borneol (22.5%) and camphor (18.8%) which are used for preparation of a fragrance and medicinal products.
Highlights
The Asteraceae family is endowed with essential oilyielding plants, in particular, the genus Artemisia occupies a top position for its bio-prospection [1]
The essential oil from the A.palustris was characterized by the presence of monoterpene hydrocarbons, among which (E)-β-ocimene(trans) and (Z)-β-ocimene(cis) were dominated (Figure 1)
In the study, chemical compositions of the essential oils of A.palustris and A.sericea, from Mongolia were investigated for the first time
Summary
The Asteraceae family is endowed with essential oilyielding plants, in particular, the genus Artemisia occupies a top position for its bio-prospection [1]. In Mongolian traditional medicine, the leaves of A.palustris show the beneficial influence for treatment of skin diseases, while the seeds are useful for treatment of bronchitis and tuberculosis [6]. The aerial parts of A.palustris growing in Siberia, Russia have known to contain flavonoids (luteolin, quercetin, hyperozide, cinarozid, and chalcones), coumarin (umbelliferone) and essential oil which mainly consisted of trans-β-ocimene (50%), cis-βocimene (40%), myrcene (2%) and some sesquiterpenes [10]. To the best of our knowledge, A.sericea has not been previously investigated for its chemical compositions and in particular, the essential oil. In the present work we analyzed the chemical compositions of the essential oils of the aerial parts A.palustris and A.sericea occurring in Mongolia and compared them with oils of other Artemisia species to determine their characteristic profile
