The dynamic headspace sample( DHS) and automatic thermal desorption-gas chromatography-mass spectrometric( ATD-GC-MS) system were applied to analyze the volatile composition of four cultivars( Zipo,Yanlong,Yankui and Zaofeng) of chestnut flowers. The results showed that 2,2,3,3,4,4-hexamethyltetrahydrofuran, tetrahydro-2,5-dimethyl-2h-pyranmethanol,2-propyl-1-pentanol,tert-butyl-3,3-dimethylbutyl ether and 2,6-diphenylphenol were main volatile compounds in four cultivars. Esters and alcohols were major volatile components in chestnut flowers. Volatile components of four cultivars were compared and the relative contents of main volatiles in Zipo were higher than those of other three cultivars. Meanwhile,Zipo has the strongest smell among four.
