Factorial design applied to concentrate bioactive component of Cymbopogon citratus essential oil using short path distillation

The effect of each variable studied on the dependent variable (CCD), is indicated by influence of EVT and Q on CCD. The increase of EVT increases CCD to 2.048 × 103 mg citral/g sample, when compared with the initial sample of essential oil, which presented a CCD of 9.908 × 102 mg citral/g sample. The linear model, statistically significant, describes the dependence of the variable CCD with the variables of the process inside the experimental range.
