| "Wormwood (Artemisia absinthium L.) essential oil obtained by steam distillation has been investigated by GC and GC/MS. The main component was determined to be either [[https://de.wikipedia.org/wiki/Thujone|(α + β) thujone]] or cis-chrysanthenol, depending upon the maturation state of the plant. In wormwood harvested after flowering period (October or November), the amount of cis-chrysanthenol may reach more than 60%. The wormwood growing in Auvergne could be considered to be a new chemotype; a cis-chrysanthenol chemotype." \\ | "Wormwood (Artemisia absinthium L.) essential oil obtained by steam distillation has been investigated by GC and GC/MS.

| "Several essential oils obtained from Artemisia absinthium L. from four localities in the Spanish Pyrenees were analyzed by GC/MS. Two chemotypes were detected; a cis-epoxyocimene type (with more than 50% of this compound) which was predominant in all the populations, and a cis-epoxyocimene + chrysanthenyl acetate type (with 25-65% of cis-epoxyocimene and 15-50% of chrysanthenyl acetate). The distribution of these chemotypes had no relation with the altitude of the samples. None of the plants tested contained thujone, a fact which could be very interesting for the food industry." \\ | "Several essential oils obtained from Artemisia absinthium L. from four localities in the Spanish Pyrenees were analyzed by GC/MS.
