| ABSTRACT: The effect of the addition of natural antioxidants on oxidative stability of ray ( Rhinoptera bonasus) liver oil was evaluated. Different concentrations of rosemary extract, α-tocopherol, and caffeic acid (w/w) were added to the oil. Afterwards, concentration of each antioxidant that gave the highest stability was used in an accelerated stability test (Schaal method). The protective effect was established by the retention in the oil of fatty acids eicosapentaenoic (EPA) and docosahexaenoic (DHA), and concentration of volatile compounds. The best concentrations were: 2.5% of rosemary extract, 0.5% of α-tocopherol, and 0.06% of caffeic acid. Rosemary extract showed to be the product with the greatest ability to retard oxidation, followed by... |

| ABSTRACT: Plants belonging to genus Jatropha has arisen interest because of its high oil content that could be used to produce biodiesel. It is also widely reported that the main fatty acids in Jatropha oilseed are oleic and linoleic acids. However, there are scarce studies related to native species of Jatropha from Northwestern Mexico which are adapted to arid conditions, and the expression of genes involved in fatty acid synthesis for these species is still unknown. Therefore, the aim of this study was to analyze the expression of five genes, ACP1, KASII, D9SD, FAD2-1 and FAD2-2, which are involved in the oleic and linoleic acids synthesis in mature wild-seeds of Jatropha cinerea, a native species from Sonoran Desert, using semi-quantitative RT-PCR.
