The chemical composition of the residues in seven ancient amphorae (IV century B.C.E.) discovered during excavations on the top of Mithridates mountain (Crimea) was investigated using a complex of complementary analytical methods, namely, FTIR spectrometry, gas chromatography, and mass spectrometry. Basing on the compounds identification, it was found that the residue contains the resin of Pinaceae...
The use of the large retention index database for identification and filtering of false positive hits in GC–MS analysis of the ylang-ylang essential oil is illustrated. Differences between experimental retention indices and database values of retention indices of candidate compounds provide additional constraints on the list of candidates for a target compound. Over 100 components of ylang-ylang essential...
