“…An interesting finding in this study was that only Middle-Friuli lavender flowers had, after distillation, the highest levels of linalyl acetate (31.7 %) and linalool (45.0 %) and the lowest of camphor (0.5 %). As it was known that good lavender contains a high proportion of linalyl acetate and linalool and a low proportion of camphor [1], [2], [3], the Middle-Friuli lavender could be evaluated as the highest quality by its content of linalyl acetate which was maintained in the essential oil.…”

“…The essential oils of lavender are generally obtained by steam distillation of the fresh flowering spikes, but this can result in the degradation of thermolabile compounds or/and an incomplete collection of compounds responsible for the fragrance. The oil produced by L. angustifolia is called lavender oil and it is characterized by high levels of linalool and linalyl acetate and a low proportion of camphor [1], [2], [3]. Commercialy, the first use of lavender essential oil was in the fragrance industry, including soaps, colognes, perfumes, deodorants and cosmetics or as an insect repellent.…”

Headspace solid-phase microextraction (HS-SPME) coupled to gas chromatography and mass spectrometry using the divinyl/carboxen/polydimethylsiloxane (DVB-CAR-PDMS) fibre was applied for the analysis of aroma profiles of Lavandula angustifolia L. flowers and the corresponding essential oils. The optimal sampling time was determined by studying the equilibrium time profile of the major volatile compounds for the lavender flowers (50 min) and the essential oil (20 min). Comparative analysis of L. Angustifolia L. cultivated in Friuli Venezia Giulia (northeastern Italy) highlighted that the contents of linalool and linalyl acetate were the major differences between the composition of flowers and the hydro-distilled products. Lavender essential oil from Middle-Friuli Venezia Giulia was evaluated as the highest quality for its high level of linalyl acetate (31.7 %) and linalool (45.0 %) and low percentage of camphor (0.5 %). The use of headspace SPME was shown to be a convenient and effective analytical tool for the sampling of volatile compounds and it could be used to test the quality of flowers and essential oils from Lavandula species.

“…The essential lavender oil grown in India consisted of linalool (28.06%) and linalyl acetate (47.5%) [34]. The major compounds of a Lavandula hybrid grown in Northern Italy were linalyl acetate and borneol, which together accounted for 70% [35]. In our study, the sum of these two compounds did not exceed 25.8% and LEO revealed a high content of linalool (41.6%), while linalyl acetate reached 23.0%; 1,8-cineole (5.2%) and camphor (6.0%) were present as secondary compounds.…”

Liquid and Vapour Phase of Lavandin (Lavandula × intermedia) Essential Oil: Chemical Composition and Antimicrobial Activity

et al. 2019

Essential oils from Lavandula genus and the obtained hybrids are widely used for different purposes such as perfume production in the cosmetic field and for its biological properties. This is the first study on the liquid and vapour phase of Lavandula × intermedia “Grosso” essential oil grown in the Lazio Region, Italy, investigated using headspace coupled to gas chromatography and mass spectrometry (HS-GC/MS). The results showed the most abundant components were linalool and linalyl acetate, followed by 1,8-cineole and terpinen-4-ol, while lavandulyl acetate and borneol were identified as minor compounds, maintaining the same proportion in both the liquid and vapour phase. Furthermore, we tested lavandin liquid and vapour phase essential oil on gram-negative bacteria (Escherichia coli, Acinetobacter bohemicus, and Pseudomonas fluorescens) and gram-positive bacteria (Bacillus cereus and Kocuria marina).

“…Moreover, several authors (Eckert et al, 2008;Raguso, 2008) have stated that the infra-specific difference in secondary metabolite production in plants has been explained by genetic drift, relaxed selective pressure, introgression of traits through hybridization, gene pleiotropic effects, and phenotypic plasticity. For instance, qualitatively and quantitatively variations in secondary metabolites have been recorded among populations of the same species (Peracino et al, 1994;Muñoz-Bertomeu et al, 2007). Three main compounds of essential oil, 1,8-cineole (20.1%), β-pinene (12.4%), germacrene D (11.6%), from NHLA decreased more than four folds compared to NHHA population.…”

Effect of altitude on essential oil composition and on glandular trichome density in three "Nepeta" species ("N. sessilifolia", "N. heliotropifolia" and "N. fissa")

et al. 2019

In the current study, the trichome density and the chemical variation of the hydrodistillated essential oils were determined along the altitudinal gradient in Nepeta sessilifolia, N. heliotropifolia, and N. fissa. The capitate glandular trichomes were predominant in all populations studied. Denser leaves indumentum was observed in high altitude populations of N. heliotropifolia, and in low altitude populations of N. sessilifolia and N. fissa. Moreover, the inter-population chemical polymorphism was detected. In the lower population of N. sessilifolia, spathulenol (14.2%) was the major compound of essential oils. This oil had great amount of oxygenated sesquiterpene (35.3%), while the oil of high altitude population had great amount of diterpenes, namely phytol (32.8%). In N. fissa, the main compound in lower population was β-caryophyllene (33.1%), whereas in the higher population it was caryophyllene oxide (21.5%). In N. heliotropifolia, 1,8-cineole (20.1%) was as the principal oil compound in low altitude population and β-caryophyllene (18.8%) in the high altitude population. We suggested that the amount of different types of monoterpenes decreases along the altitudinal gradient and the amount of oxygenated compounds increases with the elevation.
