Total % of identified compounds				91.1	84.7	78.1

Compounds were identified based on the compounds’ mass spectral data and retention indices compared with those of the NIST Mass Spectral Library (December 2011), the Wiley Registry of Mass Spectral Data, 8th edition, and many authentic standards. The content (%) was calculated in triplicate using the normalization method based on the GC-MS data. The presented data are the average of three replicas, tr—trace concentration less than 0.1%. Standard deviation did not exceed 3% for all values. KI^†: Kovats index calculated on VF-Wax CP 9205column.
