Abstract:

The conditions of solid phase micro-extraction (SPME) for extraction of volatile components in vanilla grown in
Hainan were optimized and its effectiveness was compared with that of simultaneous distillation extraction (SDE) for the
analysis of volatile components in vanilla by gas chromatography coupled with mass spectrometry (GC-MS). The results
showed the optimal SPME conditions were established using a 75 μm carboxen®/polydimethylsiloxane (CAR/PDMS) fiber
at 80 ℃ for 20 min. A total of 105 volatile components were identified, among which, 73 volatile compounds were extracted
by SDE and 78 by SPME. This study has shown that more volatile components can be extracted and identified with a
combination of SPME and SDE.

Key words: vanilla, solid phase micro-extraction, simultaneous distillation extraction, optimization
