“…The most applied analytical techniques are gas chromatography with flame ionization detection (GC-FID) [18] and gas chromatography-mass spectrometry (GC-MS). [19] They are used in essential oil therapy research to identify, compare and quantify their components.…”

Essential oils are gaining increasing interest for their antimicrobial and antiviral properties, as well as for their preventive and therapeutic actions against many human pathologies. Herein, we present an overview on new discoveries in essential oil research, discussing antimicrobial activity, as well as immunomodulatory, anti‐apoptotic, anti‐angiogenic and anti‐tumoural properties. In addition, we emphasize recent advances in the identification of bioactive components and understanding of their mechanism of action. We discuss their molecular diversity and wide spectrum of activity as well as their structure–activity relationships and capability of targeting paradoxical responses triggered by different genes and pathways. Finally, we emphasize the effort required to isolate and identify the bioactive components of essential oils and to determine their cytotoxicity as their specificity. Thus, new approaches to specifically address bioactive components to selected targets could enhance the latter property in order to accommodate any cytotoxicity towards dysfunctioning loci.

“…In this context, vibrational spectroscopy methods (nearinfrared, mid-infrared (MIR) and Raman spectroscopies) combined with chemometric treatments have been successfully introduced for a non-destructive determination of metabolites present in essential oils [11][12][13][14][15][16][17][18][19][20][21][22]. Momentarily, it is only by applying statistical methods that EOs near-infrared spectra can be interpreted, whereas the bands that are characteristic of the individual compounds can easily be seen in the MIR and Raman spectra, therefore making it possible to discriminate between essential oils.…”

International audienceLavender (Lavandula angustifolia) and lavandin (sterile hybrid of L. angustifolia P. Mill. x Lavandula latifolia (L.f.) Medikus) are widely cultivated in the Mediterranean area for produce essential oils. In this study, 80 lavandin and 55 lavender essential oil samples from various varieties were analyzed. Firstly, a chemometric treatment of mid-infrared spectra was used to evaluate the capacity of Partial Least Squares Discriminant Analysis (PLS-DA) regression to discriminate French lavandin and lavender essential oil (EO) samples and their varieties (Abrial, Fine, Grosso, Maillette, Matherone, Sumian and Super), and secondly, to quantify the main compounds such as linalyl acetate, linalool, eucalyptol and camphor by PLS regression using reference data from gas chromatography. The examination of PLS and PLS-DA regression coefficients allowed the identification of metabolomic markers. The lavender/lavandin EOs and their varieties were very well classified (100% for lavender/lavandin EOs and between 98 and 100% for varieties). The calibration models obtained by PLS regression for the determination of the main compound contents revealed good correlation (>0.86) between the predicted and reference values. This method can be used to control the authenticity and traceability of lavender/lavandin and their varieties. Finally, mid-infrared and Raman spectroscopy results were compared

“…Furthermore, there are few chiral studies on EOs of L. £ intermedia (Flores et al 2005) and it accounts for some specific molecules. Chiral distribution is an important aspect of the EO composition, it helps identifying natural EOs from those adulterated (Smelcerovic et al 2013), even when the samples come from different places of the Earth (Tranchida et al 2012). In addition, the chirality in biomolecules is highly important due to the different bioactivities and organoleptic properties of each of the enantiomers (Baser and Buchbauer 2010).…”

Lavandin (Lavandula × intermedia Emeric ex Loiseleur) essential oils (EOs), from Abrial, Super and Grosso cultivars, cultivated and extracted in the South East of Spain, were analysed by using GC/MS to determine their composition, in both relative (peak area) and absolute (using standard curves) concentrations. Linalool (34-47%), linalyl acetate (17-34%), camphor (4-9%) and eucalyptol (3-7%) were determined as the main molecules. This characterisation was completed with the enantioselective gas chromatography, where ( - )-linalool, (+)-camphor and ( - )-linalyl acetate were determined as the main components. Antioxidant activity was evaluated positively by several methods: activity against free radicals, chelating and reducing power, probably due to linalool and linalyl acetate. Mild inhibitory activity on lipoxygenase was observed supporting potential anti-inflammatory activity, mainly due to linalool and camphor. These properties support the potential use of L. × intermedia essential oils as natural cosmetic and natural pharmaceutical ingredient to fight several skin diseases.
