Abstract: | The composition of the essential oil from the wormwood sage (Artemisia frigida Willd., Asteraceae) of populations growing in the Altai Territory, the Altai Republic, the Khakass Republic, the Tuva Republic,
and the East-Kazakhstan region of the Republic of Kazakhstan and the representative species of the silver-leaved wormwood
Artemisia argyrophylla Ledeb. growing in the Republic Altai has been studied by chromato-mass spectrometry. An analysis of 15 samples of the essential
oil from A. frigida obtained over a period from 1999 to 2007 indicates that samples from different populations have similar sets of the main
components: α-pinene (0.2–7.8%), camphene (1.9–5.8%), 1,8-cineole (8.9–33.8%), camphor (6.7–40.0%), borneol (3.9–12.3%), terpine-4-ol
(1.5–6.5%), bornyl acetate (1.4–22.0%), and germacrene D (1.4–14.6%). Some samples contain substantial amounts of α- and β-thujones
(in total up to 19.1%), which are completely absent in other samples. Some samples contain santolina alcohol (up to 13.8%)
and its acetate (up to 4.8%). As differentiated from A. frigida, the essential oil of A. argyrophylla contains yomogi alcohol (1.2%), artemisia ketone (12.9%), artemisia alcohol (3.1%), artemisia alcohol acetate (3.9%), and
small amounts of camphor (3.2%), borneol (0.3%), and bornyl acetate (0.2%). |
