| Abstract: | The composition of the essential oils of 16 individual plants of Artemisia herba-alba Asso ssp. valentina (Lam.) Marcl. (at the full bloom stage) growing wild in four different locations from southern Spain were investigated by capillary GC and GC–MS in combination with retention indices. Among the 60 identified constituents (accounting for 80.6–95.0% of the oils), 33 have been reported for the first time in Spanish A. herba-alba oil and 17 of them have not been previously described in A. herba-alba oil. From the analysis of the oil samples, it could be deduced that a noticeable chemical polymorphism typified this taxon. Four groups of essential oils exhibited a single compound with percentages near 30% or higher: davanone, 1,8-cineole, chrysanthenone and cis-chrysanthenol. Two further oil types showed p-cymene and cis-chrysanthenyl acetate as major components in moderate amounts (ca. 20%). All of these types of essential oils have not been previously found in A. herba-alba from Spain and the appearance of such considerable amount of p-cymene is described here for the first time in A. herba-alba. |
