Chemical Variability of the Needle Oil of Juniperus communis ssp. alpina from Corsica

Abstract

The composition of 109 samples of essential oil isolated from the needles of Juniperus communis ssp. alpina growing wild in Corsica was investigated by GC (in combination with retention indices), GC/MS, and 13C-NMR. Forty-four compounds accounting for 86.7-96.7% of the oil were identified. The oils consisted mainly of monoterpene hydrocarbons, in particular, limonene (9.2-53.9%), beta-phellandrene (3.7-25.2%), alpha-pinene (1.4-33.7%), and sabinene (0.1-33.6%). The 109 oil compositions were submitted to k-means partitioning and principal component analysis, which allowed the distinction of two groups within the oil samples. The composition of the major group (92% of the samples) was dominated by limonene and beta-phellandrene, while the second group contained mainly sabinene beside limonene and beta-phellandrene.

Chemical Composition, Cytotoxic and Antibacterial Activities of Essential Oils of Cultivated Clones of Juniperus communis and Wild Juniperus Species

“…communis and J . indica leaves and berries showed the presence of α ‐pinene, sabinene, limonene, myrcene and terpinene as major constituents . This study also explored the presence of sabinene, α ‐pinene, limonene, 4‐terpineol, cis ‐sabinene hydrate, β ‐myrcene, α ‐terpinene, τ ‐cadinol and α ‐cedrol as major volatile components in J .…”

Essential Oils Chemistry

“…Sabinene An important compound in carrot -Daucus carota seed (Marzouki et al 2010) and in Juniperus communis oils (Ottavioli et al 2009) that also contributes to the spiciness of black pepper. This compound is used as a perfume additive (Zhang et al 2014) and has been explored as a component for the next generation of aircraft fuels (Rude and Schirmer 2009).…”

Chemical characterization and radical scavenging activity of leaves of Juniperus foetidisima, J. excelsa and J. communis from Macedonian flora

“…There is a lot of literature data concerning the chemical composition of different Juniperus species, predominantly reporting the essential oil composition of berries and leaves. Thus, for J. communis considerable variations in the leaf oil composition were observed depending on the plant origin, however the essential oils is characterized with-α-pinene, sabinene and myrcene, followed by trans-(E)-caryophyllene, muurolene, germacrene D and B and humulene (Orav et al, 2010a;Chatzopoulou and Katsiotis, 1993;Kumar et al, 2003, Ottavioli et al, 2009Filipowicz et al, 2009;Shahmir et al, 2003;Orav et al, 2010b). The major oxygen containing terpenoids were terpinen-4-ol (Chatzopoulou and Katsiotis, 1993), rarely citronellol (Koukos and Papadopoulou, 1997) and terpenyl acetate (Angioni et al, 2003).…”
