“…Linear curve was preferred a priori for its simplicity. Other curves format were tested as well on the best fitting period, as previous work showed they could fit fatty acid content as influenced by environmental parameters (sigmoidal by Izquierdo and Aguirrezábal, 2008, second degree polynomial, Baux et al, 2008).…”

“…The number of reflux cycles was 50 and the complete extraction procedure lasted from 8 to 10 h. In turn, samples were extracted in B. napus has been known as a rich source of oil with a low content of saturated fatty acids (5-7%) and a high content of polyunsaturated fatty acids w ith about 7-10% α-linolenic and 17-21% linoleic acids. It is the refore considered as very health y edible oil (Baux et al, 2008). The improvement of seed quality is one of the most important objectives in Brassica breeding for satisfying future edible oil requirements (Shengwu et al, 2003).…”

Rapeseed (Brassica napus L.) is now the third most important source of edible oil in the world after soybean and palm oil. In this study seeds of five different rapeseed cultivars namely; pactol, silvo, topas, serw 4 and serw 6 were evaluated for their fatty acid composition, glucosinolate profile, amino acids, total tocopherols and phenolic content. Among all cultivars significant variability in fatty acids were observed. The oleic acid (C18:1) ranged from 56.31% to 58.67%, linoleic acid (C18:2) from 10.52% to 13.74%, α-linolenic acid (C18:3) from 8.83% to 10.32% and erucic acid (22:1) from 0.15% to 0.91%. The glucosinolate profile of rapeseed was also separated and identified using high-performance liquid chromatography. Small variations in the glucosinolate profile were observed among all tested cultivars; however, progoitrin and gluconapin were the major glucosinolate found. Additionally, silvo cultivar showed the highest total glucosinolate c ontents (5.97 μmol/g dw). Generally, the contents of aspartic, glutamic, arginine and leucine were high, while the contents of tyrosine and isoleucine were low among all cultivars. For total tocopherols, the results indicated that both serw 6 and pactol cultivars had the highest total tocopherol contents (138.3 and 102.8 mg/100 g oil, respectively). Total phenolic contents varied from 28.0 to 35.4 mg/g dw. The highest total phenolic content was found in topas while the lowest value was detected in serw 6. These parameters; fatty acid contents, glucosinolate profile and amino acids together with total tocopherols and phenolic contents, could be taken into consideration by oilseed rape breeders as selection criteria for developing genotypes with modified seed quality traits in Brassica napus L.

La colza (Brassica napus L.) es hoy en día el tercer cultivo más importante de aceites comestibles en el mundo tras el aceite de soja y de palma. En este estudio semillas de cinco cultivos diferentes de colza, denominadas pactol, silvo, topas, serw 4 y serw 6, fueron evaluadas mediante su composición en ácidos grasos, perfil de glucosinolato, aminoácidos, tocoferoles totales y contenido fenólico. En todos los cultivos, una significativa variabilidad en los ácidos grasos fue observada. El ácido oleico (C18:1) vario desde un 56.31% a un 58.67%, ácido linoleico (C18:2) desde un 10.52% a un 13.74%, ácido α-linolenic (C18:3) desde 8.83% a un 10.32% y ácido erúcico (22:1) desde un 0.15% a un 0.91%. El perfil de glucosinolatos de colza fue también separado e identificado usando cromatografía líquida de alta eficacia. Una baja variación en el perfil de glucosinolato fue observado en todos los cultivos ensayados; sin embargo, progoitrina y gluconapina fueron los principales glucosinolatos encontraos en todos los cultivos. Además, el cultivo silvo mostro el contenido de glucosinolatos totales más alto (5.97 μmol/g dw). Generalmente, el contenido de aspártico, glutámico, arginina y leucina fue alto, mientras que el contenido de tirosina y isoleucina fue bajo en tod...

“…Temperature during seed development is generally considered to account for most of the variations in fatty acid composition (Baux et al, 2008). Other important factors are solar radiation (Izquierdo et al, 2009) and water stress (Pavlista et al, 2011).…”
