AB  - A new hyphenated extraction method composed of ultrasound assisted extraction 
      (UAE)-optimized ultrasound assisted emulsification microextraction (USAEME) was 
      developed for the extraction and preconcentration of the essential oil of 
      Elettaria cardamomum Maton. The essential oil was analyzed by gas 
      chromatography-mass spectrometry (GC-MS) and optimization was performed using gas 
      chromatography-flame ionization detection (GC-FID). Ultrasound played two 
      different roles in the extraction of the essential oil. First, as a source of 
      sufficient energy to break the oil-containing glands in order to release the oil, 
      and second as an emulsifier to disperse the organic phase within water. The 
      effective parameters (factors) of USAEME including volume of extraction solvent 
      (C(2)H(4)Cl(2)), extraction temperature and ultrasonic time were optimized by 
      using a central composite design (CCD). The optimal conditions were 120 muL for 
      extraction solvent volume, 32.5  degrees C for temperature and 10.5 min for ultrasonic 
      time. The linear dynamic ranges (LDRs) were 0.01-50 mg L(-1) with the 
      determination coefficients in the range of 0.9990-0.9999. The limits of detection 
      (LODs) and the relative standard deviations (RSDs) were 0.001-0.007 mg L(-1) and 
      3.6-6.3%, respectively. The enrichment factors were 93-98. The main components of 
      the extracted essential oil were alpha-terpenyl acetate (46.0%), 1,8-cineole (27.7%), 
      linalool (5.3%), alpha-terpineol (4.0%), linalyl acetate (3.5%).
