Abstract:

This paper describes a rapid headspace-solid phase microextraction (HS-SPME) and gas chromatography-mass spectrometric (GC-MS) method for determining the volatile compounds in ‘Chuliang’ longan. Qualification was performed by both mass spectral and retention index library searching. For semi-quantification, an internal standard solution (IS) of cyclohexanone was used. Operating conditions for headspace solid-phase micro-extraction and GC-MS were optimized. The precision RSDs for the predominant compounds in ‘Chuliang’ longan ranged from 2.12% to 9.08%. Forty-one volatile compounds were detected in ‘Chuliang’ longan and trans-ocimene (81.2%), ethanol (1.92%), allo-ocimene (1.39%), γ-terpinene (0.30%), β-myrcene (0.30%) and linalool (0.26%) were the predominant compounds. The presented method is of simple operation and most suitable for the determination of volatile compounds in ‘Chuliang’ longan.
