Abstract: A rapid determination method of volatile compounds in litchi juice was developed by headspace solid phase micro-extraction and gas chromatography-mass spectrometry (HS-SPME and GC-MS). The optimal operating conditions for headspace solid phase micro-extraction and GC-MS are as follws: extracting for 40 min at 50℃ and desorbing for 5 min at 250 ℃. The RSD of this method is 4.27%~9.33%. It is suitable for the quality control of litchi. 41 aroma compounds in" Feizixiao" litchi are determined, which are alcohols, terpenic hydrocarbons, alcohols, aldehydes, esters and fatty acids.

Key words: litchi, headspace solid phase micro-extraction, GC-MS, aroma compounds
