“…Approximately in 40% of the articles devoted to the analysis of fatty acids the matrix was oil (vegetable or animal) [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32], and all of them employed gas chromatography with FID or MS detectors. The analysis by GC-FID of fatty acids in rice oil have been carried out in several works [27][28][29][30][31][32], discussing the importance of, this matrix as source of fatty acids.…”

In this article, we present a review work on different nutraceuticals found in natural matrices together with the analytical techniques used to identify and/or quantify them with special emphasis in the period January 2005-May 2010. The work is distributed according to the different families of nutraceuticals (lipids, vitamins, proteins, glycosides, phenolic compounds, etc.) discussing the analytical techniques employed for their determination (separation, spectroscopic, hyphenated techniques, etc.). Information about the claimed health promoting effects of the different families of nutraceuticals is also provided together with data on the natural matrices in which they can be found (e.g., fruits, vegetables, plants, microalgae, cereals, milk, etc.).

Tocopherols are compounds present in oilseeds with major effect on nutritional and technological properties of seed oils. Brassica spp. mainly contain varying concentrations of a-tocopherol, with high vitamin E value, and c-tocopherol, which contributes to oil stability. The objective of this research was to select for contrasting tocopherol content and profile in Ethiopian mustard (Brassica carinata A. Braun). A collection of 211 F 4:5 lines was evaluated for tocopherol content and profile, and divergent selection was conducted till the S 3:4 generation. Selection resulted in two lines with increased tocopherol content (244 and 243 mg/ kg seed as average of four environments), one line with reduced tocopherol content (117 mg/kg), two lines with reduced a/c-tocopherol ratio (0.22 and 0.28) and two lines with increased a/c-tocopherol ratio (3.74 and 3.34). Control line C-101 averaged 196 mg/kg with a/c-tocopherol ratio of 1.10. Reduced a/c-tocopherol ratio was controlled by recessive alleles at a single locus. Seed to plant correlation was high (r = 0.92), which suggests the feasibility of selecting at the single-seed level.

“…Further research will try to elucidate whether the three genes correspond to fad3 loci and, if that is the case, which of the B or C genomes of B. carinata carries a duplicated copy of fad3 Previous studies have reported greater desaturation efficiency in B. carinata than in B. napus (Velasco et al, 1998), which resulted in much higher linolenic acid content in all zero‐erucic acid germplasms of B. carinata developed so far (Alonso et al, 1991; Getinet et al, 1994; Fernández‐Martínez et al, 2001) as compared with zero‐erucic acid germplasm of B. napus (Scarth and McVetty, 1999). The high desaturation efficiency of B. carinata has allowed the development of specialty oil types with high levels of polyunsaturated fatty acids (Nabloussi et al, 2008). Such a high desaturation efficiency of B. carinata could respond to an extra active copy of fad3 , which would explain the three‐gene model identified in the present research for low linolenic acid content in this species.…”

“…In contrast, zero‐erucic acid lines of Ethiopian mustard ( Brassica carinata A. Braun) have about twofold higher linolenic acid content in their seed oils, around 210 g kg −1 (Alonso et al, 1991; Getinet et al, 1994; Fernández‐Martínez et al, 2001). Such a high linolenic acid content relates to a particularly high desaturation efficiency in Ethiopian mustard germplasm (Velasco et al, 1998), which has enabled the development of lines with very high polyunsaturated fatty acid content (Nabloussi et al, 2008). However, the high linolenic acid content of Ethiopian mustard seed oil is an undesirable characteristic for most of the potential uses of the oil.…”

Zero‐erucic acid Ethiopian mustard (Brassica carinata A. Braun) seed oil has very high linolenic acid content (210 g kg−1), which confers low oxidative stability to the oil. The line AB4 with low linolenic acid content (<30 g kg−1) has been developed. The objective of this research was to study the inheritance of low linolenic acid content in AB4. Plants of AB4 were reciprocally crossed with plants of the line 25X‐1, with wild‐type linolenic acid content. A genetic study was conducted through the analysis of the fatty acid profile of F1, F2, and F3 seed generations. Low linolenic acid content in AB4 seeds was partially recessive and not subject to maternal nor to cytoplasmic effects. F2 seeds segregated following a 1:63 (<17:>23 g kg−1) ratio, which suggested segregation of alleles at three independent loci. The three‐gene model was confirmed in the analysis of linolenic acid content in F2:3 families. Nine out of 341 F2:3 families had stable low linolenic acid content, which fitted the 1:63 ratio observed in the F2 Additionally, 1:2:1 (<8:12–33:>35 g kg−1), 1:4:11 (<8:25 – 40:>43 g kg−1), and 1:6:57 (<7:27 – 43:>47 g kg−1) segregation ratios were identified in F2:3 families, which confirmed a genetic model of three independent loci with additive effects for low linolenic acid content in the Ethiopian mustard line AB4.
