      steam-distillation conditions.

AB  - The effect of the distillation time on the yield and chemical composition of the 
      bark essential oil of Cedrelopsis grevei Baill. was investigated. Distillation 
      kinetics were determined for three batches of bark sampled from two sites, i.e., 
      Itampolo (batches IT1 and IT2) and Salary (SAL), located in a region in the south 
      of Madagascar with characteristically large populations of C. grevei. The bark 
      samples were subjected to steam distillation, and the essential oil was collected 
      at 3-h intervals. The total yield (calculated after 14 h of distillation) varied 
      from 0.9 to 1.7%, according to the batch tested. Moreover, the essential oils 
      obtained were characterized by GC-FID and GC/MS analyses. During the course of 
      the distillation, the relative percentages of the most volatile components 
      (monoterpenes and sesquiterpene hydrocarbons) diminished progressively, whereas 
      the least volatile ones (oxygenated derivatives) increased at a consistent rate. 
      Principal component analysis (PCA) and agglomerative hierarchical clustering 
      analysis (AHC) of the results, performed on 13 principal components, allowed 
      distinguishing three chemical groups, corresponding to the three batches, 
      irrespective of the distillation time. This indicated that the chemical 
      variability currently observed with commercial samples is not mainly linked to 
      the experimental conditions of the extraction process, as the distillation time 
      did not significantly alter the chemical composition of the essential oils.
