Variation in volatile components was studied in green tea manufactured in Suncheon region of Korea. The volatile compounds were characterized by headspace-GC/MS. 3-Hydroxy pentene, 2-propenal, ethyl hexanol, ethylene-heptanal acetaldehyde, methyl decanoate, isopentyl dodecanoate, and ethyl phenylacetate were the major volatile components in the green tea. High-grade green tea is manufactured in spring (from end of April to early in May) in Suncheon region. The volatile compound was detected on 28 April (1st), 5 May (2nd), 12 May (3rd) and 19 May (4th), 2012. The qualitative and quantitative differences were shown in volatile components between the first half sample (1st and 2nd samples) and the second half sample (3rd and 4th samples). The number of volatile components of the first half sample was more than that of the second half sample, and on the other hand the content of major constituents of the second half sample was more than that of the first half sample with the exception of isopentyl dodecanoate and ethyl phenylacetate.
