Essential oil mixture

Analysis The identification of the composition of a substance. Physical methods used for essential oil mixtures include GC-MS. The identification of substances is called qualitative analysis, while the estimation of the amounts of components present is quantitative analysis. 

A 50-ml Erlemneyer flask is connected with a glass tube (U-shaped, 10- to 15-cm long, 5 mm in diameter). 1 g powdered drug and 10 ml water are then heated to boiling in the flask and a distillation via the U-tube is performed slowly until about 1 ml of the water-essential oil mixture has been collected in the test tube. With 1 ml pentane, the lipophilic compounds are dissolved by shaking in the upper phase the lipophilic solution is removed with a pipette and 20-100 pi is used for TLC investigation. 

Supplementation of 200 ppm essential oil mixture (EOM) that included oregano, clove, and anise oils (no species name or composition given ) in broiler diets was said to sign cantly improve the daily live weight gain and feed conversion ratio (FCR) during a growing period of 5 weeks (Ertas et al., 2006). Similar results were obtained with 400 mg/kg anise oil (composition not known ) (Ciftci et al., 2005).

Using the results of your GC-MS analysis, prepare a brief report describing your experimental method and presenting the results of your analysis. In your report, be sure to identify each important component of the essential oil you analyzed, draw its complete structural formula, and indicate the relative percentage of that substance in the essential oil mixture.
