“…Table 1 and for lavandin EOs in Table 2 . ( −)-Linalool (13.11-53.73%) and ( −)-linalyl acetate (17.34-54.89%) were the main constituents and their enantiomeric composition was in accordance with literature [36,38,44] : linalyl acetate was found with high ee ( > 99%), while the two enantiomers of linalool were confirmed in all the varieties studied (ee between 88 and 94%). Enantiomeric distribution of linalyl acetate and linalool, the main compounds of lavender/lavandin EOs were already used to identify adulteration [45] have not been detected in EOs. This enantiopurity is a characteristic of Mediterranean EOs as already reported by Mosandl and coll.…”

Polarimetric HPLC detector was used to acquire chromatograms for lavender/lavandin essentials oils (EOs) on different chiral stationary phases. Amylose tris-(3,5-dichloro-phenylcarbamate) immobilized on silica allowed the best separation of the numerous chiral phytomarkers and was thus used to obtain a chiroptical fingerprint for 158 samples of French lavender/lavandin EOs. Samples from different varieties (Abrial, Fine, Grosso, Maillette, Matherone, Sumian and Super) were collected over three crop years (2012, 2013 and 2014), from four different locations in France ("Alpes-de-Haute-Provence", "Ardèche", "Drôme" and "Vaucluse") to take into account seasonal and geographic origin variations. The combination of the polarimetric fingerprints and chemometrics was tested for varietal discrimination. We assessed the ability to discriminate the EOs samples and their variety by partial least squares-discriminant analysis (PLS-DA). This case study showed that liquid chromatography with polarimetric detector in tandem with chemometric analysis was efficient to differentiate the varietal origins of French lavender/lavandin EOs.

“…Considering the relevance of the enantiomeric composition of linalool and linalyl acetate in authenticity studies previously demonstrated by other authors [16,17], our interest was to take advantage of the potential of SFE for enantiomeric studies. Initially, the enantiomeric separation was accomplished on a 25 m60.25 mm fused silica capillary column with a 0.25 lm layer of Chirasil-b-Dex by GC-MS.…”

Characteristic aroma compounds in plants and essential oils of Lavandula from different varieties were examined. The study of the qualitative and quantitative composition of the major volatile components was faced by developing a method based on the use of supercritical fluid extraction-GC-MS (SFE-GC-MS). The optimization of a variety of parameters affecting SFE extraction enabled RSDs from three replicates lower than 2% to be achieved. Equally, recoveries of up to 59% were obtained by applying the proposed method. The use of multidimensional GC was necessary to enantiomerically resolve the target compounds. The obtained results showed enantiomeric purities >90% for all studied compounds in all varieties considered, proving the natural invariability of the enantiomeric composition of the compounds of interest. This information can be useful in authenticity studies as well as in selecting natural sources of enantiomerically pure compounds.

“…Only this species reached comparable essential oil yields to those of typical aromatic crops, such as those belonging to the botanical family of Lamiaceae, that is Satureja hortensis L. (about 2%, Baher et al ., ), Lavandula spp. (2–9%, Renaud et al ., ) and Origanum vulgare L. (2.5–4%, Azizi et al ., ). The other species belonging to the genus Artemisia ( A. verlotiorum ) showed comparable yields to others reported for the Mediterranean environment (Vernin, ).…”

Weeds for weed control: Asteraceae essential oils as natural herbicides

et al. 2017

The aim of this study was to test the botanical family of\ud Asteraceae as a source of natural herbicides. Twenty\ud Asteraceae species were collected during flowering time\ud and evaluated in terms of the yield and quality of essential\ud oils (germination inhibition and growth of weeds).\ud Half the species showed a sufficient yield of essential oil\ud (from about 0.1% to 1.43%) when testing these phytochemicals\ud in vitro as germination inhibitors of two typical\ud weeds, Amaranthus retroflexus and Setaria viridis.\ud Despite the higher tolerance of S. viridis, the concentration\ud of 100 lg L\ud 1 of essential oils of the two Artemisia\ud species and Xanthium strumarium could totally inhibit\ud germination. In addition, at 10 lg L\ud 1, the same essential\ud oils showed full inhibition of A. retroflexus seeds. A\ud comparison of their effectiveness at suboptimal doses\ud led to a further selection of the most promising sources\ud of essential oils. After their chemical characterisation,\ud the essential oils were tested as post-emergence herbicides\ud on seedlings of the above-cited weeds. After spraying\ud the weeds at different concentrations (10, 100 and\ud 1000 mg L\ud 1) during two different phenological stages\ud of weed seedlings (cotyledons and the third true leaf),\ud the essential oils of Artemisia annua and X. strumarium\ud showed the best performance. The essential oils of\ud X. strumarium were then tested again on both weeds to\ud monitor the dynamics of plant injury. A reduction in\ud plant fresh weight (about 20%–30% after 10 days) and\ud chlorophyll content (destroyed, after the same amount\ud of time) was found, thus confirming the total and rapid\ud effectiveness of these essential oils. In summary, A. annua\ud and X. strumarium have elicited considerable agronomic\ud interest and appear to be suitable as a source of\ud essential oils to act as natural herbicides
