Essential Oil Composition ofPinus halepensisMill. from Three Different Regions of Algeria

Abstract

Needles of Pinus halepensis Mill. were collected from three different locations at Sidi Feradj (SF), Djelfa (Dj) and Saïda (Sd) in Algeria. Their oils isolated by hydrodistillation yielding 0.5% from SF, 0.8% from Dj and 0.9% from Sd, have been investigated for their components by means of GC and GC/MS techniques. More then 41 compounds were identified in the needle oils of Sidi Feradj (SF) and Saïda (Sd) and 39 compounds in Djelfa (Dj). The main constituents of three samples of P. halepensis leaf oil were β-caryophyllene (19.8-25.8%), followed by α-humulene (6.2%) in SF and 10.5% in Sd and aromadendrene (8.5%) in Dj, while the third constituents were aromadendrene (4.2%) in SF and α-pinene (5.2%) in Dj and 6.4% in Sd.

Chemical variability and antioxidant activities among Pinus halepensis Mill. essential oils provenances, depending on geographic variation and environmental conditions

“…The observed yields were comparable to those reported in the literature (Tazerouti et al, 1993;Roussis et al, 1995;Hmamouchi et al, 2001;Macchioni et al, 2003;Dob et al, 2007;Tumen et al, 2010;Abi-Ayad et al, 2011;Ustun et al, 2012).…”

“…Our results showed the presence of caryophyllene oxide (0-12.5%) as a major component, which was also the major component at 48.2% and 0.4-7.8% in the essential oils from Ghazaouet (T 1 ) and Turkey, respectively, but, it was absent in the case of Greece, Italy, Morocco, Turkey and the rest areas from Algeria. Furthermore, the humulene oxide and thumbergol were present in the essential oils from Ghazaouet (T 1 ) at 6.7% and 8.3%, respectively, while, they were absent in our results and those of the previous studies (Tazerouti et al, 1993;Roussis et al, 1995;Hmamouchi et al, 2001;Macchioni et al, 2003;Dob et al, 2007;Tumen et al, 2010;Abi-Ayad et al, 2011;Ustun et al, 2012). This chemical variability among provenances led to conclude that geographic variation may influence the essential oils components either in quantitative and qualitative extent.…”

“…P. halepensis is known by their medicinal properties as well as its economic importance (Acherar et al, 1984;Barbero et al, 1990;Polge, 1992;Tatoni et al, 1994;Nasri et al, 2005;Kurose et al, 2007). Chemical composition, antimicrobial activities and genetic side of this species have been reported (Nahal, 1962;Debazac and Tomassone, 1965;Calamassi, 1986;Schiller et al, 1986;Schiller and Grundwald, 1987;Tazerouti et al, 1993;Roussis et al, 1995;Baradat et al, 1995;Kaundun et al, 1998;Hmamouchi et al, 2001;Macchioni et al, 2003;Dob et al, 2007;Tumen et al, 2010;Abi-Ayad et al, 2011;Ustun et al, 2012). These studies report that diversity in P. halepensis did not follow a regular pattern and was a complex mixture of natural migration and human interventions.…”

“…20 . However, this yield was different in other regions, as in three different locations at Sidi Feradj, Djelfa and Saïda in Algeria, whose oils hydrodistillation yields were 0.5 , 0.8 and 0.9 56 , respectively. Moreover, the terpenic compounds of P. halepensis have bactericidal, fungicidal, insecticidal, anticarcinogenic, pesticidal, antioxidant, analgesic and sedative effects 57 .…”

Chemical analysis of phenolic compounds and determination of antioxidant, antimicrobial and cytotoxic activities of organic extracts of Pinus coulteri

“…Some pine such as P. pinaster, P. halepensis, P. brutia, P. radiata, P. pinea, P. nigra and other have been extensively researched (chemical composition and biological activities, morphological and geographical variation, gene ecology and genetic side) (Ait Mimoune et al, 2013;Dob et al, 2007;Ustun et al, 2012;Yesil-Celiktas et al, 2009;Calamassi, 1986), there are comparably few studies that have been conducted on the biological activities and the phenolic composition of the extracts from other pine species.…”
