“…Given its relatively high content in Terminalia catappa oil, this oil could constitute a potential risk for cardiovascular disease, as some authors have pointed out Keys A, Dubois V et al [15,16]. Oleic acid is the majority fatty acid in olive oil with contents ranging from 55 to 83% [17]. The beneficial health effect attributed to olive oil is partly due to its high oleic acid content, which is attributed a cholesterol-lowering effect [17].…”

The oleic acid contents of Coula edulis, Moringa oleifera Cyperus esculentus oil are within a range of the oleic acid contents of olive oil.…”

Aims: This study aims to determine the fatty acid, sterol and total polyphenol composition of Ricinodendron heudelotii, Terminalia catappa, Moringa oleifera, Cyperus esculentus, Sesamum indicum and Coula edulis oils. Study Design: Plant material consisting of almonds of Ricinodendron. heudelotii, Terminalia catappa, Moringa oleifera, rhizomes of, Cyperus esculentus, seeds of Sesamum indicum and hazelnuts of Coula edulis were collected in different producing areas of Côte d'Ivoire in 2017. Place and Duration of Study: This study was conducted between November 2017 and June 2018 at the Laboratory of Industrial Processes, Synthesis, Environment and New Energies, National Polytechnic Institute Félix Houphouët-Boigny, Côte d'Ivoire. Methodology: The extraction of oil from the oil-bearing organs of different plants was carried out by maceration of the crushed parts of these organs in hexane at a crushed/solvent ratio of 1:10 (grams/volume) for 6 hours at cold temperature. These oils were analyzed by gas chromatography for the determination of fatty acid profile, then by gas chromatography coupled with a mass spectrometer for the determination of sterols and Ultraviolet-visible spectrophotometer for the quantification of polyphenols. Results: The results show a fatty acid composition of the different oils dominated by four fatty acids: oleic (18.89 - 93.93%), linoleic (1.03 - 43.2%), palmitic (2.65 - 35.6%) and stearic (1.09 - 11.66%). We also note average unsaponifiable matter (0.5 - 1.71%) and sterols dominated by sitosterol, stigmasterol and campesterol. Concerning polyphenols, the values obtained range from 52.09 to 863.67 µg gallic acid equivalent/g oil. Conclusion: The presence of sterols, phenolic compounds and unsaturated fatty acids in interesting proportions show that these oils are important sources of edible oils beneficial to human health.

“…SFA content of PO is close to that of lard, which is composed of 45% SFA [ 15 ]. Olive oil (OO) is very rich in unsaturated fatty acids [ 16 ] and polyphenols [ 17 ]. These properties give it nutritional benefits [ 18 , 19 ].…”

Palm oil (crude or refined) and lard are rich in SFA, while olive oil is rich in polyunsaturated fatty acids. SFA are considered harmful to health, while polyunsaturated fatty acids are beneficial to health. The aim of this study was to determine the effect of diets rich in crude PO, refined PO, OO, or lard on the mitochondrial membrane, the activity of mitochondrial respiratory chain complexes, and mitochondrial biogenesis. This was an experimental study in male Wistar rats fed a diet containing 30% of each oil. Rats had free access to food and water. After being fed for 12 weeks, animals were sacrificed and liver mitochondria were collected. This collection was used to determine membrane potential and ROS production, membrane phospholipid and fatty acid composition, citrate synthase activity and respiratory chain complex, cardiolipin synthase protein expression, and expression of selected genes involved in mitochondrial biogenesis. We found that diets rich in olive oil, palm oil, or lard altered mitochondrial biogenesis by significantly decreasing Pgc1α gene expression and altered the fatty acid composition of rat liver mitochondrial membrane PL.

Oxidation has been related to several diseases in humans. Indeed, to protect the body from high free radical damages, organism requires natural resources of antioxidant compounds, such as phenols, tocopherols (α, β, γ, and σ) which have important roles in the cell antioxidant defense system. In Mediterranean areas, olive oils and pepper fruits are considered among the best foods in a diet, which keeps on attracting the interest of scientists due to the health benefits linked with its consumption. The Olive oil and pepper fruits are among the most consumed nutrients in the Mediterranean diet; their richness in naturally powerful antioxidants, such as alpha-tocopherols, polyphenols, carotenoïds, and capsaicinoïds (specific of capsicum species), and monounsaturated fatty acids in olive and seed pepper oils, constitutes good health protection against oxidative damages and inflammation. Also, these phytochemicals shield and prevent the human body from many diseases such as cardiovascular, coronary, Alzheimer’s diseases, and cancers.
