GC-MS Analysis on Aroma Components in Three Basils
The aroma components of three basils (Ocimum basilicum, Ocimum tashiroi Hayata, Ocimum gratissimum)were analyzed by GC/MS technology. The results showed that there were differences in both aroma kinds and relative contents among the three basils. There were 37 kinds of aroma components in Ocimum basilicum, and the relative content was 91.15%. 21 kinds of aroma components in Ocimum tashiroi Hayata and the relative content was 95.08%. 29 kinds of aroma components in Ocimum gratissimum and the relative content was 89.49%. The major compounds of aroma were alcohol and hydrocarbons, their total relative contents were 84.39%、 78.61% and 77.88% in the three cultivars respectively. The three basils shared one major aroma component, Bicycloheptane, 6, 6-dimethyl-2-methylene-, (1S)of. Eucalyptol, Benzene, 1-methoxy-4-(1-propenyl)-and Cyclofenchene were the proper major aroma components of Ocimum basilicum, Ocimum tashiroi Hayata and Ocimum gratissimum, respectively.
