^aKI_exp = retention indices are determined using n-alkanes (C₇-C₁₇).
^bKI_lit = 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.
