Compositional characteristics of the essential oil of Artemisia campestris var. glutinosa

The chemical variations of the essential oil from the aerial parts of Artemisia campestris var. glutinosa have been studied. Plant material has been harvested at each phenological status (vegetative, before anthesis, full flowering and seed-bearing). Analysis by GC and GUMS of the essential oils have allowed to identify 51 components. The main components were gamma-terpinene, capillene, 1-phenyl-2,4-pentadiyne, spathulenol, methyleugenol, p-cymene and pinene. Aromatic polyacetylens have been characterized for the first time in this species. Flowering involves an increase of these compounds in the essential oil. (C) 2002 Elsevier Science Ltd.
