High tocopherol and triacylglycerol contents inPinuspineaL. seeds

Abstract

Oleaginous seeds are among the functional foods most recognized for their tocopherols and triacylglycerols because of their role in lipid metabolism. In this paper, the tocopherol and triacylglycerol contents in seeds of several Pinus pinea L. populations around the Mediterranean Basin were investigated. Lipids were extracted from fully ripen seeds with petroleum ether. The tocopherol (alpha-tocopherol, gamma-tocopherol, and delta-tocopherol) contents were, respectively, 15.34+/-3.75 ppm, 1,681.75+/-404.03 ppm and 41.87+/-9.79 ppm. Lipids (mainly triacylglycerols) in P. pinea seeds averaged 48% on a dry weight basis. Triacylglycerols with an equivalent carbon number of 44 (32.27%) and of 46 (30.91%) were dominant. The major triacylglycerol was LLO (24.06%). Tocopherols and triacylglycerols were present at remarkably high levels, thus making P. pinea oil a valuable source of antioxidants and unsaturated fatty acids with varying levels across the geographical range of P. pinea.

Triacylglycerols and Phospholipids Composition of Caper Seeds (Capparis spinosa)

“…These results agree with other researchers who reported that the TAG content of Pinus pinea can vary among populations [18]. Moreover, TAG composition can vary among species [19,20].…”

Triacylglycerols and aliphatic alcohols from fruits of three Tunisian Pistacia lentiscus populations

“…A determination of the TAG composition of Pistacia atlantica fruit, a related species belonging to the Anacardiaceae family, shows the prevalence of PLO (8%) and POO (15%), which is consistent with our results. In contrast, the occurrence of TAG molecular species in some vegetable oils showed that in almond, olive and Pinus pinea , the major species are, respectively, LLL, OOO and LLO . Furthermore, our results show that P. lentiscus oil is rich in di‐ and tri‐unsaturated TAGs (OLP, POO etc.)…”

Fatty acids and triacylglycerols composition from Tunisian Acacia species seed oil

“…The obtained results were slightly different to that of some common seed oils in which the linoleic acid is the major fatty acid such as soybean oil (16% OLL, 7% LLLn, 2% OOO, and 8% OOL) and Pinus pinea seed oil which has 24.38% LLO, 17.82% LOO, 11.31% PLO, and 7.5% POO (Padley, 1994;Nasri et al, 2009). Our results agreed with other authors Figure 1 Chromatogram of TAG from Acacia species.…”

“…Our results agreed with other authors Figure 1 Chromatogram of TAG from Acacia species. Tunisian Acacia species seed oil who reported that the TAG content can vary among populations and also can vary among species (Crane et al, 2005;Nasri et al, 2009). Spady and Dietschy (1985) have suggested that saturated dietary TAG inhibit the activity of hepatic LDL receptors in the Hamster.…”
