“…First, ethanol and isopropanol are less polar than methanol in the BD method [as observed by Zief and Kiser (18)]; second, the solubility of polar lipids is low in hydrocarbon solvents, such as hexane, when compared with their solubility in chloroform (15). When the results obtained using the chloroform/ methanol/water solvent system were compared with that of hexane/propan-2-ol/water (19), the former had a higher extraction yield.…”

Nine extraction methods (three using chlorinated and six nonchlorinated solvents) were compared for determining lipids in samples of low-(<5%) and high-fat (>20%) ground beef. The nine methods investigated were: Folch, Lees, and Sloane Stanley (FLS); Bligh and Dyer (BD); Bligh and Dyer modified by Undeland, Harrod, and Lingnert (BDU); Bligh and Dyer modified by Smedes (BDS); Hara and Radin (HR); Schmid, Bondzynski, and Ratzalaff (SBR); Roese-Gottlieb (RG); Burton, Webb, and Ingold (BWI); and Soxhlet (SE). The BDS and HR methods do not include solvents such as chloroform and methanol and can be recommended for meat samples that have both low and high fat content. If the use of organic solvents is not critical, the FLS and the BD extraction methods yield the highest results, but the FLS is more expensive owing to the high amount of solvent required. Without considering the toxicity of the solvents, the three BD extraction methods provided the best yields.

“…It has been shown that chloroform/methanol extraction could result in higher overall lipid yields than other solvents or solvent pairs by dissolving more polar substances, such as polar lipids (Gunnlaugsdottir and Ackman, 1993). In order to reduce the solvent toxicity from chloroform, alternative solvents or solvent pairs have also been tested, such as methyltert-butyl ether (Matyash et al, 2008), hexane (Danielewicz et al, 2011), and hexane/isopropanol (Hara and Radin, 1978).…”

Diatoms are one major group of algae in oceans that accounts almost half of marine primary food production and have also been identified as a promising candidate for biofuel production for their high level accumulation of lipids. They have gained increasingly attention for their potential applications in pharmaceuticals, cosmetics, nutrient supplements, and biofuels. This review aims to summarize the recent advances in diatom lipid study. Chemical structures and bioactivities of different lipid classes are discussed with a focus on valuable lipids such as fatty acids, polar lipids, steroids, and oxylipins from various diatoms species. Further, current extraction and fractionation approaches are compared and recent analytical techniques and methods are also reviewed with an emphasis on lipid class composition and fatty acid profiling. Biosynthetic pathways and key catalyzing enzymes are illustrated for a better understanding of fatty acid metabolism. Past engineering attempts toward generating appropriate diatom strains for lipid production are discussed with examples using mutagenesis, environmental stimulants, and genetic modification methods. Some possible future directions and applications of diatom-derived lipids are also proposed.

“…Nos últimos anos diversos pesquisadores realizaram trabalhos 16,17,[19][20][21][22][23] em que o objetivo foi encontrar o método mais eficiente para a obtenção da fração lipídica desejada e determinar sua composição. Além disso, também buscaram métodos que não alterassem a qualidade do óleo e utilizassem solventes menos tóxicos que a mistura clorofórmio e metanol.…”
