“…En outre, L'acide oléique (C18 : 1 ω9) était le principal acide gras monoinsaturé chez les feuilles les deux cultivars. De même, l'acide oléique était l'acide principal dans la composition en acides gras saturés de plusieurs espèces végétales telles que labrusca et V. vinifera (Santos et al, 2011), Achillea millefolium (Dias et al, 2013) et certaines espèces de Fabaceae (Keskin et al, 2013). Les feuilles des arbres fruitiers sont plus riches en acide gras polyinsaturé.…”

This work falls within the framework of quantitatively evaluating the primary metabolites and qualitatively the secondary metabolites of the three inedible organs (bark, leaves and flowers) of the two pomegranate cultivars (Nabli and Gabsi) in order to better enhance this natural resource. . The main objective is to carry out a global study which focuses on both the study of the biochemical composition and the organoleptic study of inedible organs. The results show that protein, sugar and fatty acid composition accumulate differently depending on the cultivar. These by-products can be considered as a potential crop that could be useful in designating pomegranate by-products as an ingredient in food processing, which could provide potential health benefits. In addition, the infusions of bark, flowers and leaves have organoleptic characteristics adapted to the requirements of the panellists. We can conclude that these extracts can be used in human food.

Objective:The aim of the study was to investigate quantitative and qualitative fatty acid profiles of the gonad and liver tissue of femaleMethods:Total lipids were extracted with 5 mL of chloroform-methanol (2:1 v/v). Samples containing gonad and liver lipid were transesterified with acidified methanol. The fatty acid methyl esters were extracted with hexane. Fatty acids were detected by gas chromatography (GC).Results:The major saturated fatty acids (SFAs) were myristic acid (C14:0), palmitic acid (C16:0) and stearic acid (C18:0) in both gonad and liver tissue. Oleic acid (C18:1 ω-9) and palmitoleic acid (C16:1 ω-7) were the prominent monounsaturated fatty acid (MUFA). The dominant polyunsaturated fatty acids (PUFAs) were linoleic acid (LA, C18:2 ω-6), arachidonic acid (AA, C20:4 ω-6), docosapentaenoic acid (C22:5 ω-3) and docoesahexaenoic acid (DHA, C22:6 ω-3). The ratio of ω-3/ω-6 ranged from 1.55 to 3.44 and 1.18 to 2.71 in the gonad and liver tissue, respectively.Conclusion:The findings of this study will be useful for understanding the seasonal distribution of fatty acid composition in the liver and gonad of spiny eel.

Abstract:Adenocarpus complicatus is distributed throughout the Anatolian peninsula and is widely used for human and animal nutrition. The purpose of this work was to study the antioxidant properties and fatty acid composition of different parts of this plant (fruits and mixed materials). The species was collected from Golyuzu village of the Seydisehir district near Konya province, Turkey. Fruit and mixed parts obtained from this species were ground and a 15g sample was used to prepare methanolic extracts. Powdered plant samples were extracted with 100mL methanol in a mechanical shaker. The obtained extracts were filtered and concentrated to dryness under reduced pressure and were subsequently stored at -20°C. Antioxidant components, namely total phenolic and flavonoid content, were detected for each extract using spectrophotometric methods. Antioxidant capacity was evaluated by various assays including phosphomolybdenum, DPPH free radical scavenging capacity, metal chelating activity, and ferric and cupric ion reducing power. The fatty acid profiles of plant parts were also determined by using gas chromatography. The total phenolic content of fruit (36.21mgGAE/g) was higher than that of mixed materials (13.79mgGAE/g). The methanolic extract of mixed material had higher amounts of flavonoid than fruit extract. The free radical scavenging activity of extracts was expressed as iC 50 value (µg/mL) (amount required to inhibit DPPH radical formation by 50%). The lower iC 50 value reflects better free radical scavenging action. The radical scavenging activity of the samples was compared with BHT, it showed the mixed material to be almost two times more potent than the fruit extract. However, BHT is an excellent free radical scavenger with an iC 50 of 34.061µg/mL. The ferric and cupric reducing power potentials of the extracts were expressed as EC 50 value (the effective concentration at which the absorbance was 0.5). Fruit extract exhibited strong ferric reducing power with an EC 50 of 871.25µg/mL. The metal chelating activity of the extracts increased with concentration. Chelating effect was 83.60% for fruit extract at 1mg/mL concentration. Oil content of fruit and mixed parts were detected as 6.71 and 6.14%, respectively. A total of 32 fatty acids were found in the oil. Essential fatty acids (linoleic and α-linolenic acid) were identified as the most abundant fatty acids in the oil. These results demonstrated that this plant species can be considered as an alternative to synthetic antioxidants. Likewise, the oil obtained from the plant can be used as a source of essential fatty acids for food and pharmacological applications. Rev. Biol. Trop. 62 (1): 337-346. Epub 2014 March 01.
