aKIexp = retention indices are determined using n-alkanes (C7-C17).
bKIlit = retention indices of reference compounds from literature.
cID = Identification methods; MS = comparison of the mass spectrum with those of the computer mass libraries, and Adams (2007); RI = comparison of calculated RI with those reported in the literature.
dCompounds are listed in order of their retention time; the names and the percentages of main compounds are indicated in bold.
