“…This was also studied by Trabelsi et al (2011), who showed the same profile for oleic and palmitic acids and a highest percentage of the linoleic one. This could be related to the difference in the method used for oil extraction or to the year of fruits harvest.…”

This study was performed on oil extracted from mature fruits of Pistacia lentiscus L. harvested from Northern and North Western Tunisia. Extraction was done by two methods: Traditional method practiced by women in forest areas and pressing method that was proposed to improve the yield and the quality of oil. Fatty acid composition was determined by gas chromatography-mass spectrometry (GC/MS). Oleic acid was the main fatty acid with more than 56%, followed by palmitic with 27%. Antioxidant activity of these oils was improved by pressing method; the percentage of inhibition of DPPH was increased from 21 to 43% for Nefza provenance and from 19 to 29% for Bizerte one. Similarly, the highest values of trolox equivalent antioxidant capacity (TEAC) were reached by oils extracted by pressing method. Antibacterial activity was tested against three strains: Escherichia coli, Salmonella typhimurium and Clostridium perfringens. The results showed the existence of a significant bactericidal effect in the case of C. perfringens for oils from Bizerte with an inhibition diameter of about 13 mm for the oil extracted by pressing method and 8 mm for that extracted by traditional one. The effect was not significant in the case of E. coli and S. typhimurium.

“…The protective effect of PLo is owed to its high contents of powerful antioxidants, which certainly play an important role in vivo, particularly the unsaturated and saturated fatty acids such as oleic acid, palmitoleic acid, linoleic acid, palmitic acid and stearic acid (Charef et al, 2008;Djerrou, 2014;Trabelsi et al, 2012), polyphenols, including tannins and flavonoids (Bhouri et al, 2010), a-tocoperol (Kivçak & Akay, 2005), sterols and monoterpenes (Gardeli et al, 2008).…”

Context: Pistacia lentiscus L. (Anacardiaceae) is an evergreen shrub widely distributed throughout the Mediterranean region. Pistacia lentiscus oil (PLo) was particularly known in North African traditional medicine. Thus, people of these regions have used it externally to treat sore throats, burns and wounds, as well as they employed it internally for respiratory allergies. PLo is rich in essential fatty acids, vitamin E and polyphenols. As a very active site of metabolism, liver is reported to be susceptible to arsenic (As) intoxication.Objective: The present study evaluates the protective effect of PLo against sodium arseniteinduced hepatic dysfunction and oxidative stress in experimental Wistar rats. Materials and methods: Twenty-eight rats were equally divided into four groups; the first served as a control, the remaining groups were respectively treated with PLo (3.3 mL/kg body weight), sodium arsenite (5.55 mg/kg body weight) and a combination of sodium arsenite and PLo. After 21 consecutive days, cellular functions were evaluated by hematological, biochemical and oxidative stress markers. Results: A significant decrease in the levels of red blood cells, haemoglobin (p 0.001), hematocrit (p 0.001), reduced glutathione and metallothionein (p 0.05) associated with a significant increase of malondialdehyde (p 0.001) were noticed in the arsenic-exposed group when compared to the control. The As-treated group also exhibited an increase in hepatic antioxidant enzymes namely superoxide dismutase, glutathione peroxidase (p 0.01) and catalase (p 0.05). However, the co-administration of PLo has relatively reduced arsenic effect. Conclusion: The results showed that arsenic intoxication disturbed the liver pro-oxidant/ antioxidant status. PLo co-administration mitigates arsenic-induced oxidative damage in rat.

“…The vegetable oil extracted from the same region in 2014 has shown a high level of Monounsaturated Fatty Acids (MUFA: 55.76%), a 20.45% of Poly Unsaturated Fatty Acids (PUFA), a 23.53% of Saturated Fatty Acids (SFA) with a good ratio of PUFA/SFA (ratio = 0.86) (Djerrou, 2014). The unsaponifiable fraction of P. lentiscus fatty oil contains sterols (cholesterol, campesterol, stigmasterol and β-sitosterol), tocopherols and phenolic components (Djerrou et al, 2010;Trabelsi et al, 2012). Several components existing in this oil were investigated and confirmed to be implicated in preventing hyperlipidemia, LDL oxidation and prevention of atherosclerosis as: Oleic acid (C18:1), Omega-3 PUFAs, Conjugated Linoleic Acids (CLAs), α-tocopherol, squalenes and phenolic components (Harris et al, 1997;Newmark, 1997;Kohr et al, 1998;Kris-Etherton, 1999;Visioli et al, 2002).…”

Abstract:The study aimed to evaluate Pistacia Lentiscus Virgin Fatty Oil (PLVFO) effects on lipidemic profile and carcass characteristics in rabbits. 15 male adult rabbits were allocated in three groups of 5 each. The first was not treated and served as control (CRL), the second was gavaged by Egg Yolk (EY) at a dose of 7 mL kg −1 BW (6/7 days), the third was treated as EY and then PLVFO was applied at a dose of 1 mL kg −1 BW (6/7 days). At 28th day of experiment, the biochemical profiles were determined and then animals were sacrified for anatomopathological studies and carcass characteristics investigation. PLVFO has resulted in non significant decrease of total cholesterol, a significant decrease of LDL-C (PLVFO Vs EY, ANOVA, p<0.01) and a significant increase of HDL-C (PLVFO Vs EY, ANOVA, p<0.001) with a significant amelioration of atherogenic index (PLVFO Vs EY, ANOVA, p<0.01). This oil has also increased non significantly ALT with a significant increase of AST (PLVFO Vs EY, ANOVA, p<0.01). Anatomo pathological investigations have not shown significant disturbances by PLVFO, this later has reduced significantly dissectible fat (PLVFO Vs EY, ANOVA, p<0.05). The study concludes that PLVFO prevent hyperlipidemia and obesity at tested dose. However, its prolonged use may increase transaminases enzymes activities.
