a RIdet, retention index determined relative to C7–C30 saturated alkanes run under identical chromatographic conditions; b RIref, reference retention index retrieved from online databases of NIST Chemistry WebBook [18] (https://webbook.nist.gov/chemistry/, accessed on 20 March 2021) and ChemSpider [19] (https://www.chemspider.com/, accessed on 21 March 2021). Certain RIref values were retrieved from our previous studies [8,9]; c Compounds identified by mass spectra and retention indices; d Code for cultivar name, see Table 1. Percentages of individual components are presented as mean value of triplicate samples (RSD basically below 10% for major components); tr, trace, percentages lower than 0.05%; -, not detected; * Compounds tentatively identified.
