coupled with an ion trap mass detector and equipped with a capillary column Elite-ms5, methylpolysiloxane (5% phenyl, 30 m, 0.25 mm i.d. and 0.25 mm coating thickness) was used. The chro- matographic conditions were 40?C initial temperature for 3 min; rate 1 of 10?C/min until to reach 100?C; rate 2 of 15?C/min until to reach 245?C. The injector temperature was 250?C. Direct liquid injection (1 mL) of the essential oil using a 5 mL Hamilton syringe was performed for analysis.
