This study investigated the volatile phytochem. diversity of 30 samples obtained from exptl. hybrid and com. H. lupulus L. plants. Essential oils distilled from these samples were analyzed by high resolution gas chromatog. coupled with accurate mass time-of-flight mass spectrometry (GC-accTOFMS). A total of 58 secondary metabolites, mainly comprising 18 esters, 6 monoterpene hydrocarbons, 2 oxygenated monoterpenes, 20 sesquiterpene hydrocarbons, 7 oxygenated sesquiterpenes, and 4 ketones, were pos. or tentatively identified. A total of 24 metabolites were detected in all samples, but com. cultivars (selected for brewing performance) had fewer compounds identified compared to exptl. genotypes. Chemometrics analyses enabled distinct differentiation of exptl. hybrids from com. cultivars, discussed in terms of the different classes of compounds present in different genotypes. Differences among the mono- and sesquiterpenoids, appear to be related to either: i) the genetic origin of the plants; or ii) the processes of bioaccumulation of the identified secondary metabolites. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Synthetic Route of C8H16O2).
Methyl heptanoate (cas: 106-73-0) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
