Abstract
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).
Highlights
The genus Lavandula belongs to the Lamiaceae family, a medicinal aromatic plant family whose essential oils (EOs) are widely used for applications in food, perfumery, and in the field of cosmetics; it is important for human health given its potential biological activities [1,2,3,4,5,6].Lavandula species are found worldwide and consist of over 39 species, besides various intraspecific taxa and hybrids, which differ in colour and period of flowering, foliage, and resistance to low temperatures [7]
Lavandula angustifolia, Lavandula latifolia, and Lavandula × intermedia Emeric ex Loisel, a natural sterile hybrid obtained by crossing L. angustifolia × L. latifolia are mainly used to produce EOs
Gas Chromatography–Mass Spectrometry (GC–mass spectrometer (MS)) analysis of the liquid phase showed the presence of 26 compounds (Table 1), of which
Summary
Lavandula species are found worldwide and consist of over 39 species, besides various intraspecific taxa and hybrids, which differ in colour and period of flowering, foliage, and resistance to low temperatures [7]. Lavandula angustifolia ( called L. officinalis or L. vera), Lavandula latifolia (spike lavender), and Lavandula × intermedia Emeric ex Loisel (lavandin or lavandulil), a natural sterile hybrid obtained by crossing L. angustifolia × L. latifolia are mainly used to produce EOs. L. Lavandin is a much larger plant than the L. angustifolia varieties and is much appreciated for its EO yield. This product is widely used all over the world by the fragrance industry and is a common ingredient in soaps, laundry detergents, skin care, perfumes, and cleaning products
