Chemical Composition of the Essential Oil of the New Cultivars of Lavandula angustifolia Mill. Bred in Ukraine

Abstract

Lavender, otherwise known as Lavandula angustifolia Mill., is widely used in landscaping, and its oil is a valuable raw material used in many industries. Therefore, new varieties of this plant are bred. The essential oil composition obtained from fresh flowers of thirteen new Ukrainian cultivars of L. angustifolia were analysed by GC-MS, and eighty-two components were identified. Linalool and linalyl acetate were principal constituents of all of the samples, and ranged from 11.4% to 46.7% and 7.4% to 44.2%, respectively. None of the studied samples fulfilled the requirements of Ph. Eur. and ISO 3515:2002. The main reason was a high content of α-terpineol (0.5–4.5%) and/or terpinene-4-ol (1.2–18.7%). Our results are in line with multiple researchers showing that the studied lavender oils do not comply with the industry standards despite their authenticity. We also investigated the effect of the growth year on the chemical composition of five tested cultivars grown on the same plots and noticed a considerable variability between years. The obtained experimental data did not show a significant inter-year trend for the content changes of the major components. Our results allow us to deeply characterize the new cultivars and evaluate their oil for a possible use in the industry, or to designate them for future selective breeding.

Comparative Evaluation of the Essential Oil of the New Ukrainian Lavandula angustifolia and Lavandula x intermedia Cultivars Grown on the Same Plots

“…β -ocimene may be present in true lavender EOs at levels of 2–18% and 0.5–6% for cis - and trans -isomers, respectively, and in lavandin oil at levels of 2–15% and 0.2–9% for cis - and trans -isomers, respectively [ 11 , 15 , 16 , 17 ]. High levels of eucalyptol and camphor may also be present in LA oil (from 0.1 to 44 and from traces to 28%, respectively) but the mentioned high values predominate in the essential oils from lavender leaves and stems or flowers from some unique special chemotypes [ 11 , 18 , 19 ]. Usually, the oils obtained from flowering tops of L. angustifolia contain low levels of these compounds—from traces up to 2%.…”

Examination of VOC Concentration of Aroma Essential Oils and Their Major VOCs Diffused in Room Air

“…Essential oils: Four types of essential oils (scientific name and vender), lavender (Lavandula angustifolia, Ryohin Keikaku Co., Ltd., Tokyo, Japan), tea tree (Melaleuca alternifolia, Ryohin Keikaku Co., Ltd., Tokyo, Japan), eucalyptus (Eucalyptus, Ryohin Keikaku Co., Ltd., Tokyo, Japan), and melissa (Melissa officinalis, Insent Co., Nagano, Japan), were used in this study. Major components in the essential oils are researched from a text of phytotherapy [ 11 ] and reference papers and internet websites [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ], as listed in Table 1 .…”

Challenges in Medicinal and Aromatic Plants DNA Barcoding—Lessons from the Lamiaceae

“…(English Lavender), L. stoechas L. (French Lavender), L. latifolia Medik. (Mediterranean lavender) and L. × intermedia (lavandin, which is a cross between L. latifolia and L. angustifolia) [ 185 ]. Lavender oil, obtained from the flowers of L. angustifoliais chiefly composed of linalyl acetate (3,7-dimethyl-1,6-octadien-3yl acetate), linalool (3,7-dimethylocta-1,6-dien-3-ol), lavandulol, 1,8-cineole, lavandulyl acetate, and camphor [ 186 , 187 ].…”
