“…Similar results were observed for PC species profiles (Figure 10). There may be an overrepresentation of cyclic FA species in ESI-MS, but, in general, the TAG and PC lipid compositions by MALDI-MSI were similar to those obtained by conventional quantitative techniques, and these were all in good agreement with values reported in the literature for cottonseed lipid species quantified by other methods (e.g., high performance liquid chromatography/ thin layer chromatography/GC; Lísa and Holcapek, 2008;Dowd et al, 2010;Dowd, 2011). It should be noted that the same approach has been taken by Murphy and coworkers in comparison of each PC molecular species of rat brain cross sections between MALDI-MSI and liquid chromatography-MS/MS analysis, and quantitative agreement was found regardless of the tissue type (Hankin and Murphy, 2010).…”

Spatial Mapping of Lipids at Cellular Resolution in Embryos of Cotton

Advances in mass spectrometry (MS) have made comprehensive lipidomics analysis of complex tissues relatively commonplace. These compositional analyses, although able to resolve hundreds of molecular species of lipids in single extracts, lose the original cellular context from which these lipids are derived. Recently, high-resolution MS of individual lipid droplets from seed tissues indicated organelle-to-organelle variation in lipid composition, suggesting that heterogeneity of lipid distributions at the cellular level may be prevalent. Here, we employed matrix-assisted laser desorption/ ionization-MS imaging (MALDI-MSI) approaches to visualize lipid species directly in seed tissues of upland cotton (Gossypium hirsutum). MS imaging of cryosections of mature cotton embryos revealed a distinct, heterogeneous distribution of molecular species of triacylglycerols and phosphatidylcholines, the major storage and membrane lipid classes in cotton embryos. Other lipids were imaged, including phosphatidylethanolamines, phosphatidic acids, sterols, and gossypol, indicating the broad range of metabolites and applications for this chemical visualization approach. We conclude that comprehensive lipidomics images generated by MALDI-MSI report accurate, relative amounts of lipid species in plant tissues and reveal previously unseen differences in spatial distributions providing for a new level of understanding in cellular biochemistry.

“…The fatty acid (FA) profile of CSO comprises linoleic (55.38%), oleic (14.53%), and palmitic (27.39%) acids residues (Okonkwo and Okafor, 2016). Because of its FA content, CSO has been cited as suitable for shortenings, margarines, salad oil and biofuels (Dowd, 2011). Furthermore, CSO contains bioactive compounds such as antioxidants, including tocopherols, sterols, and flavonoids (Mariod and Mattäus, 2011;Nix et al, 2017), as well as pigments (gossypol; Tian et al, 2016), which can be useful for the enrichment, fortification of flavour and stabilization of shelf life for food and medical applications.…”

“…Subroto et al found that increasing the moisture content of the kernel increases the phosphorus content of the oil (Subroto et al, 2015). (O'Brien, 2002). Indeed, B.aegyptiaca and C.pentandra oils contain a significant quantity of polyunsaturated acids 45.38 and 39.43%, respectively.…”

The metals in vegetable oils derived from raw materials or transported by contact with the manufacturing or storage equipment reduce the oxidation stability of the oils involved in rancidity processes (O'Brien, 2002;Agarwal et al, 2003;Garrido et al, 1994). The presence of iron and copper in hexane extracted oils indicates their natural origin.…”

Non-edible vegetable oils have a huge potential for many industrial applications. Most of them are expressed by mechanical pressing, but data on the different operating conditions to achieve optimal extraction yields and high-quality oil are scarce. Hence, the objective of this study was to optimize key hydraulic extraction parameters at ambient temperature (25 °C) of Balanites aegyptiaca and Ceiba pentandra oils by increasing the oil recovery. Optimal holding time, applied pressure, compression speed, and press cage charge were determined for whole and crushed oleaginous material. The results indicate that the B.aegyptiaca kernels and C.pentandra seeds contained 2.7 and 5.7% moisture, as well as 46.3 and 26.2% fat, respectively. Under the optimal operating conditions, the oil recovery (wt.%. d.b.) from whole (crushed) material was 73.4 (69.8) B.aegyptiaca kernels and 38.2 (41.2) C.pentandra seeds. The extracted oils have a high content of unsaturated fatty acids including of about 74 wt.% for B. aegyptiaca and 69 wt.% for C.pentandra. They were particularly rich in linoleic ω-6 acid, 45.32 and 38.77 wt.%, respectively. The chemical characteristics of cold-extracted B. aegyptiaca and C.pentandra oils were 10 and 20 ppm phosphorus, 2.8 and 3.5 ppm iron, 0.0 ppm copper, 0.06 and 0.1% water-volatile matter, respectively. These valuable material properties make the B.aegyptiaca and C.pentandra oils an ecological and renewable resource for multipurpose applications.
