Abstract
The volatile components of fennel bean were extracted by head space solid phase microextraction(HS-SPME) and analyzed by gas chromatography mass spectrometry(GC-MS).The optimum operating conditions for SPME were determined as following: head space adsorption at 55 ℃ for 60 min using a 75 μm Carboxen/PDMS fiber.A total of 38 compounds were identified,representing 86.87% of the total peak area and consisted of 15 hydrocarbons,13 aldehydes and ketones,3 alcohols,3 phenols,3 ethers and 4 other compounds.The prevailing compounds were 1-methoxy-4-(1-propenyl) benzene(40.75%),nonanal(4.16%),cis-anethole(3.77%),limonene(3.48%),and estragole(2.9%).
