Composition of the essential oil and of some extracts of the aerial parts of Artemisia ludoviciana var. latiloba Nutt
AUTHOR(S): Guy Collin, Alexis St-Gelais, Maxime Turcotte and Hélène Gagnon
ABSTRACT:The essential oil of Artemisia ludoviciana is generally characterized by a high percentage of oxygenated monoterpenes (> 70%) such as camphor (~20%), borneol (~15%), and 1, 8-cineole (>10%). These three components seem very common in the essential oil obtained from plants collected in various part of the world, although percentages may be very different as we observed in our own samples. Microwave and CO2 supercritical extracts were also studied. Several of the terpenes observed in the essential oil are also identified in these extracts with camphor and borneol as the main monoterpenes. Noticeable is the presence of irregular terpenes such as artemisia alcohol and its acetate, yomogi alcohol… particularly in the microwave extract. Several guaianolides, particularly leucomisin, achillin, austricin, matricarin… as well as 4H-1-benzopyran-4-one derivatives (eupatilin, chrysosplenetin…) are present in the extracts. Finally, from the mass spectra and retention indices, 5-n-nonadecyl-, 5-n-heneicosyl- and 5-n-tricosyl-1,3-benzenediols (resorcinols) are proposed as new compounds.
