Identification of Essential Oil Constituents of Caraway (carum Carvi) Using Ultrasonic Assist with Headspace Solid Phase Microextraction (ua-hs-spme)

چکیده
Ultrasonic assist with headspace solid phase microextraction (UA-HS-SPME) have been applied, for the first time, for the extraction of volatile organic compounds of Carum carvi L. from Iran. The oils obtained were analyzed by GC–MS. Different experimental parameters such as fiber's coating type, sonication time, extraction time and temperature, and desorption time were investigated. Results showed that in the presence of UA-HSSPME the highest extraction efficiency was achieved with a 100 μm polydimethylsiloxane (PDMS) fiber. Essential oil analysis showed that 10 compounds were identified through UA-HS-SPME-GC/MS method .The major component were carvone (57.7 %) and limonone (35.5 %).
