RESEARCHES REGARDING THE ESSENTIAL OIL COMPOSITION OF SOME ARTEMISIA L. SPECIES

The chemical composition of the essential oils of Artemisia sp. L. growing in Romania has been studied. Analysis of the essential oil extracted by hydrodistillation was performed by GC-MS and emphasised the presence of some major similar compounds in Artemisia austriaca Jack, A. lerchiana Weber ex. Stechm and A. santonica L.: eucaliptol, camphor, cis-verbenone and borneol or iso-borneol. The essential oil extracted from another species had a specifically composition. Thus, A. annua L. essential oil contained 60,20% artemisia ketone; A. dracunculus L. contained 42,34% sabinene and 24,92% methyl eugenol; A. vulgaris L. contained 41,46 germacrene D and 11,19% -caryophyllene; A. dzevanovskyi Leonova in Wulf. 57,13% eucaliptol and 20,37% borneol; A. absinthium L. contained 41,65 % -pinene and 12,77 % myrtenil acetate; A. abrotanum L. contained 12,27 % eucaliptol and 9,23 % borneol.
