Variations in the Chemical Composition of the Essential Oil of Lavandula angustifolia Mill., Moldoveanca 4 Romanian Variety

Abstract

In this research, the variations in the chemical composition of the Lavandula angustifolia Mill. essential oil, the Romanian variety Moldoveanca 4, obtained from the same culture, in the same harvesting and extraction conditions, during the years 2016-2018, representing the years 2-4 of culture. Lavandula angustifolia Mill. flowers were supplied from an ecological-crops from N-E Romania and the essential oils were obtained by hydro distillation of freshly harvested flowers. To determine the chemical composition, the essential oil was semi-quantitatively analysed by using gas chromatography coupled with mass spectrometry (GC-MS). In all the samples, 30 organic compounds were identified, linalool and linalyl acetate being in similar concentrations (23.51-27.39% for linalool and 26.60-40.66% for linalyl acetate). Changes in chemical composition were observed in 2017 and 2018. Also, in 2017 was determined an increase in the quantity of linalyl acetate (from 26.60 to 40.66 %), and a slight decrease in linalool content; in 2018, the concentration in linalyl acetate remained approximately the same as in 2017 (38.03 versus 40.66 %) and there was an increase in linalool compared to the previous years (27.39 %, compared to 23.51 % in 2017 and 26.22 % in 2016). The chemical composition of the essential oils obtained from flowers of Lavandula angustifolia L., Moldoveanca 4 variety, showed substantial changes of the chemical profile describing the compounds during the analysed three years, as was determined by GC-MS analyses.

Bio-Evaluation of the Wound Healing Activity of Artemisia judaica L. as Part of the Plant’s Use in Traditional Medicine; Phytochemical, Antioxidant, Anti-Inflammatory, and Antibiofilm Properties of the Plant’s Essential Oils

“…Several parameters have been reported as influencing factors affecting essential oil production, constituents, and quality; the parameters include the maturity stage of the plant, the oil extraction processes, and the drying methods applied to the aromatic plant samples, as well as the environmental conditions where the aromatic plant grows [ 62 , 63 , 64 , 65 ]. The essential oil of wild ArJ growing in the Northern Qassim region of Saudi Arabia has been isolated by the hydro-distillation technique using a Clevenger apparatus from the shade-dried aerial parts of the plant.…”

Chemical Profile, Antioxidant Capacity, and Antimicrobial Activity of Essential Oils Extracted from Three Different Varieties (Moldoveanca 4, Vis Magic 10, and Alba 7) of Lavandula angustifolia

“…The chemical composition of LEOs fluctuates according to variety and pedoclimatic conditions and influences their action [ 11 , 27 , 28 ]. The complete chemical composition of the mentioned LEOs ( 1 —LEO Var.…”

“…EO of lavender (LEO) is one of the most popular EO known that can be extracted from several varieties of this plant; moreover, four significant varieties of lavender must be mentioned as the most relevant for this plant, namely, Lavandula angustifolia (recognized as the commercial lavender and being the most extensively cultivated), Lavandula latifolia , Lavandula stoechas , and Lavandula x intermedia (which is a sterile cross between L. angustifolia and L. latifolia ) [ 10 ]. All EOs obtained from different varieties of lavender are volatile, being composed of aromatic substances, more precisely mixtures (synthesized by plants organs) of secondary metabolites mainly comprising groups of correlated biosynthetic compounds (i.e., C10–C15 terpene, known as isoprene derivatives, aromatics, and/or aliphatic compounds, having low molecular weight) which are giving the characteristic smell (aroma) of this plant [ 11 ].…”

“…), and the procedure used to obtain the EO (extraction with an organic solvent, extraction of the supercritical fluid/liquid using carbon dioxide, maceration, percolation, steam or fractional distillation, etc.) [ 11 ].…”

Current Trends for Lavender (Lavandula angustifolia Mill.) Crops and Products with Emphasis on Essential Oil Quality

“…The common monoterpenoids in lavender essential oil are: alcohols, esters, ketones and oxides [ 24 ]. The main component in lavender essential oil is linalool, both esterified in the form of linalyl acetate as well as free [ 92 ].…”
