Fatty acids, bioactive lipids and radical scavenging activity of Celastrus paniculatus Willd. seed oil

Chemical Characterization and Antioxidant Activity of Amazonian (Ecuador) Caryodendron orinocense Karst. and Bactris gasipaes Kunth Seed Oils

“…2 . The significant strongest antiradical action of C. orinocense oil, as reported in literature for other vegetable oils 30 may be due to different factors as a the higher level of α-tocopherol, which posesses in vitro the most antioxidant effectiveness among all tocopherols, together with the total amounts of vitamin E that are both considerably higher than B. gasipaes oil and slightly lower than extravirgin oil, b the highest unsaponifiable value 30 , c the highest content of PUFA polyunsaturated fatty acids , specifically linoleic acid with respect to other two oils. In fact, the susceptibility of fatty acids to oxidation that is their antioxidant properties is thought to be directly dependent on their degree of unsaturation.…”

“…Even if some differences between α-and δ-tocopherol amounts have been detected with previously published data 8 for Nuez de Barinas of Venezuela, the total content of vitamin E was in good agreement, corresponding to the 1.0 of unsaponifiable matter. In B. gasipaes, Vitamin E quantity was 1.9 of unsaponifiable matter, with the predominance of α-tocopherol, known to have the most effective antioxidant capacity among the isomers 30 . These quantitative data are considerably higher than that reported in literature 59 ppm vs 12-18 ppm 6 .…”

Characterization of fatty acids, bioactive lipids, and radical scavenging activity of Canterbury bells seed oil

“…The RSA of C. medium oil and olive oil was assayed with DPPH radical previously dissolved in toluene according to Ramadan et al (2009). A toluene solution of DPPH radicals was freshly prepared at a concentration of 10 −4 M. The radical was stable for more than 2 h of kinetic assay in the absence of antioxidant compounds.…”

“…Non-traditional seeds are being considered because their constituents have unique properties and may augment the supply of functional products. Owing to their medicinal properties and the health-boosting constituents, non-conventional oils are used in the healthcare industry (Ramadan et al, 2009). Apart from triacylglycerols, crude natural oils containa number of bioactive lipid compounds with a very diverse chemical makeup.…”

Bioactive lipids and fatty acids profile of Cistanche phelypaea

“…They are of interest due to their impact on health. Recently, sterols have been added to vegetable oils as an example of a successful functional food (Ntanios 2001;Ramadan et al 2009). This type of products is now available and has been scientifically proven to lower blood LDL-cholesterol by around 10-15 % as part of a healthy diet (Jones et al 2000).…”
