All data are presented as means ± SD and are expressed as % of peak areas in the gas chromatograms. The identification of the peaks have been performed by authentic references and the identified peaks were >97% of the total GC peaks.
Superscripts show the results of ANOVA analysis, as follows:
^aHigher than UNT-Y, p < 0.05;
^bLower than UNT-Y, p < 0.05;
^cHigher than UNT-O, p < 0.05;
^dLower than UNT-O, p < 0.05;
^eHigher than HT, p < 0.05;
^fLower than HT, p < 0.05;
^gHigher than LT, p < 0.05;
^hLower than LT, p < 0.05.
