title: Chemical Composition Variability of the Herb Essential Oil in the Ontogenesis of Artemisia campestris subsp. campestris.
abstract: The essential oil from the herb of Artemisia campestris L. subsp. campestris harvested at five ontogenesis phases was analyzed by GC, GC/MS and 1H NMR spectroscopy. More than 130 compounds were identified. Terpene hydrocarbons dominated in the oil. Germacrene D (20.3-30.1%), β-pinene (3.7-15.4%) and γ-humulene (6.6-9.8%) were the main constituents. The contents of germacrene D and γ-humulene decreased from the phase before bud formation to the beginning of flowering, then increased until the post-flowering phase. The content of β-pinene at the same periods firstly increased, and then was reduced.
