Abstract:

The volatile components of Qingshanlvshui Tea were extracted using solid phase micro-extraction (SPME) and accelerated solvent extraction (ASE), and then were identified by gas chromatography-mass spectrometry (GC-MS). It showed that ninety-one compounds were identified, including forty-nine by SPME, fifty-six by ASE, and fourteen by both of them. The main constituents were β-myrcene, 3,5,5-trimethyl-1,5-heptadiene, L-limonene, α-ocimene, β-ocimene, β-pinene, 2-methylbenzaldehyde, 5-(hydroxymethyl)-2-furfural. Both SPME and ASE have their advantages. SPME is excellent at simplicity, rapidity, solvent-free, high enrichment, low detection limit, environment friendly etc. ASE has characteristics of time and solvent saving, automation, simplicity, as well as high efficiency.

Key words: accelerated solvent extraction (ASE), gas chromatography-mass spectrometry (GC-MS), Qingshanlvshui Tea , volatile components, solid phase microextraction (SPME)
