Typical G.C. analysis

artemisia absinthium herb oil poland
In 1993, Kalemba et al. compared the composition of oils obtained from Artemisia absinthum (absinthe) grown in Poland, using GC and GC/MS as their method of analysis. Oils produced from plants harvested at the pre-flowering stage, in full bloom and after flowering were found to possess quantitative differences in their compositions as shown in Table XI. In addition, the authors found that the oil was strongly toxic to Rhizopertha dominca (lesser grain boror), mildly toxic to Tribolium confusum (darkling grain beetle) and Sitophilus granarius (grain weevil). Also, it was repellent to S. granarius. Only the full-flowering analysis will be shown here.
