For each sample, data are mean values of three replicates. RIt, relative retention indices on polar column reported in literature by www.pherobase.com; www.flavornet.org; www.ChemSpider.com; webbook.nist.gov (accessed on 1 July 2022); Risp, relative retention indices calculated against n-alkanes (C8-C40) on HP-Innowax column; ID, identification method as indicated by the following: RI, Kovats retention index on a HP-Innowax column; MS, NIST and Wiley libraries spectra; S, co-injection with authentic standard compounds on the HP-Innowax column.
