“…Given that previous reports indicate that Thunnus specimens are rich in PUFAs, particularly in omega‐3 fatty acids such as DHA (Visentainer et al ., ; Chotimarkorn et al ., ; Eom et al ., ; An & Choe, ), it is fair to hypothesise that the chemical treatment used in this method may have interfered and/or modified the fatty acid profile of the oil. This is in agreement with several studies showing that changes in extraction efficiency can affect the fatty acid profile due to the degradation of these molecules by the chemical solvent used (Xiao et al ., ; Vaisali et al ., ). As such, extraction parameters such as the chemical solvent may result in the removal of desirable oil components, such as PUFAs.…”

“…This observation supports the views of Jabeen & Chaudhry () and Xiao et al . () that claim that the ratio of omega‐3 fatty acids: omega‐6 can be a useful quality indicator, and the nutritional value of fish oils. Comparing the quality of the oils obtained through different extraction methods indicated that EHO is the method that best preserves the characteristics of the oil obtained from tuna by‐products.…”

Summary This study evaluated the quality of oil extracted from yellowfin tuna (Thunnus albacares) by enzymatic hydrolysis (EHO) compared with oil extracted by traditional methods, such as the physical method of cooking and pressing after fishmeal production and the chemical solvent method. The oil extracted by EHO presented the lowest acidity (1.96% oleic acid) and peroxide indexes (5.14 mEq O2 kg−1 of oil) and the highest levels of eicosapentaenoic acid (6.05g 100 g−1) and docosahexaenoic acid (27.15 g 100 g−1), two omega‐3 fatty acids with high nutritional value. Importantly, oil extraction from yellowfin tuna heads using EHO produced oil rich in omega‐3s with no oxidation. This study shows that this extraction method greatly increases the value of fish by‐products and increases the competitiveness of the fishing industry.

“…37,38 Nestes métodos, é realizada a evaporação total do solvente e a dosagem lipídica é quantificada pela diferença do peso da vidraria vazia ao se iniciar a análise e vidraria com a fase lipídica, após a extração lipídica. 39 Dentre as metodologias amplamente empregadas para a extração lipídica, destacase o procedimento proposto por Soxhlet (1879), que utiliza a extração a quente com o refluxo de solvente puro, que pode ser éter de petróleo, éter dietílico ou n-hexano. Porém, este método deve ser evitado para a extração lipídica de LH, pois contribui para que ocorra processos de peroxidação e hidrólise lipídica.…”

Human milk is considered the ideal and most complete food for the neonate, due to its balanced nutritional composition, which contributes to the full physical and neurological development of the infant. The lipids present in human milk are sources of saturated, monounsaturated and polyunsaturated fatty acids. The polyunsaturated fatty acids of the omega-6 series, such as linoleic acid and omega-3 series, such as α-linolenic acid, are essential and are also precursors of long-chain polyunsaturated fatty acids, such as arachidonic acid, eicosapentaenoic acid and docosahexaenoic acid, which are involved in a number of functions, such as the development of the nervous system during childhood and the increase in the intelligence quotient of the infant. Due to the lipid importance of human milk, the aim of this review article was to present the analytical methods that are currently being employed to determine its lipid composition. There are few scientific advances in lipid extraction methods and to date, most studies have evaluated the composition of fatty acids by gas chromatography. Liquid chromatography and mass spectrometry have been widely used to identify and quantify different classes of lipids of human milk. O leite humano é considerado o alimento ideal e mais completo para o neonato, devido à sua composição nutricional equilibrada, contribuindo para o pleno desenvolvimento físico e neurológico do lactente. Os lipídios presentes no leite humano são fontes de ácidos graxos saturados, monoinsaturados e poliinsaturados. Os ácidos graxos poli-insaturados da série ômega-6, como o ácido linoleico e da série ômega-3, como o α-linolênico, são essenciais e também são precursores de ácidos graxos poli-insaturados de cadeia longa, como o ácido araquidônico, ácido eicosapentaenoico e ácido docosahexaenoico, que estão envolvidos no desenvolvimento do sistema nervoso e no aumento do quociente de inteligência do lactente. Devido à importância lipídica do leite humano, o objetivo deste artigo de revisão foi apresentar os métodos analíticos que têm sido atualmente mais empregados para determinar sua composição lipídica. Há poucos avanços científicos quanto aos métodos de extração lipídica e até o presente momento, grande parte dos estudos avaliaram, a composição em ácidos graxos, a partir de cromatografia em fase gasosa. A cromatografia líquida e a espectrometria de massas têm sido utilizadas para identificação e quantificação de distintas classes lipídicas presentes no leite humano.

“…Fatty acids (FAs) are another class of bioactive compounds that make up an important part of the human diet (de Koning et al 2001). They could be classified into unsaturated and saturated fatty acids, which both play an inevitable role in human health and nutrition (Smith et al 2013;Xiao et al 2012). Also, poly-unsaturated fatty acids (PUFAs), as a health-supporting nutrients, have the unique medicinal and preventing properties toward inflammatory, heart diseases, atherosclerosis, autoimmune disorder, diabetes, eczema, dermatitis, asthma, rheumatoid arthritis, atherosclerosis, diabetes, obesityeven cancer and other diseases (Belch and Hill 2000;Leventhal et al 1993; Sierra-Cantor and Guerrero-Fajardo 2017; Kaurinovic et al 2011;Xiao et al 2012;Ramadan et al 2006).…”

Background: In this research, different active phytochemical constituents present in Cleome heratensis (C. heratensis) from Capparaceae family were investigated. Moreover, the fatty acids present in the seed and aerial parts of the plant were identified by gas chromatography (GC) after esterification of the oil. Antioxidant activity of the aerial parts and seed of C. heratensis methanolic extract over 2,2′-diphenylpicryl-1-hydrazyl (DPPH) was investigated using ultravioletvisible (UV-Vis) spectrophotometer. Methods: To study total phenolic compounds and flavonoids, the plant was extracted from ethanol by ultrasonic method, then further extracted with other solvents. Amounts of anthocyanins and tannins/condensed tannins were determined by their corresponding ethanolic and acetone extracts. Antioxidant activity of the plant species was studied by a spectrophotometric method using 80% methanolic extract. Results: The high content of phenolics as 16.915 mg tannic acid equivalents per gram of dry matter (TAE/g DM), tannins (12.231 mg TA/gr DM) and condensed tannins (4.086 mg TA/g DM) was obtained for the C. heratensis extract. The most flavonoids content was found 4.444 rutin equivalents (in mg) per gram of dry matter (mg RE/g DM) in plant's aerial extract. The most amount of anthocyanin (0.48 mmol/gr WM) was observed in flowering stage. Antioxidant activity of the aerial parts and seed of C. heratensis methanolic extract were 11.92 and 63.54 mg/mL IC 50 , respectively. Conclusion: High level of phenolic components including flavonoids, proanthocyanidins and tannins was detected in the extract of aerial parts of the plant. The oil of seed of this plant is a rich source of saturated and unsaturated fatty acids. Finally, C. heratensis aerial part extract was found as an excellent natural antioxidant.
