^A Linear retention index, obtained through the modulated chromatogram, reported for DB-5MS apolar column; ^B linear retention index reported for DB-5MS column or equivalents reported in the literature; ^C content is the peak volume percentage of compounds in the essential oil sample; ^D 1 = retention index identical to bibliography; 2 = identification based on comparison of MS; 3 = retention time identical to authentic compounds. Compounds are classified in order of linear retention time of non-polar column. ^E Sign: significance at p < 0.05. Results followed by different letters in the same line are significantly different (p < 0.05) according to Tukey’s multiple range test.
