The extracts obtained from sweet basil (Ocimum basilicum L.) by hydrodistillation and supercritical fluid extraction (SFE) were qualitative and quantitative analyzed by GC-MS and GC-FID. Essential oil (EO) content of basil sample, determined by an official method, was 0.565% (V/w). The yields of basil obtained by SFE were from 0.719 to 1.483% (w/w), depending on the supercritical fluid (carbon dioxide) density (from 0.378 to 0.929 g mL-1). The dominant compounds detected in all investigated samples (EO obtained by hydrodistil- lation and different SFE extracts) were: linalool, as the major compound of basil EO (con- tent from 10.14 to 49.79%, w/w), eugenol (from 3.74 to 9.78%) and δ -cardinene (from 3.94 to 8.07%). The quantitative results of GC-MS from peak areas and by GC-FID using exter- nal standard method involving main standards, were compared and discussed.
