Separation and identification of lipids and fatty acids of the marine algaFucus vesiculosus by TLC and GC—MS

Antitumor activity of fucoidan in anaplastic thyroid cancer via apoptosis and anti-angiogenesis

“…Extraction of fucoidan. F. vesiculosus was collected from the coast of the Baltic Sea and the identity of the specimens was confirmed as previously described (21,22). The fucoidan used in the present study was isolated from the extract of F. vesiculosus in 20:80 ethyl acetate:hexane using column Antitumor activity of fucoidan in anaplastic thyroid cancer via apoptosis and anti-angiogenesis chromatography and was characterized using 1 H nuclear magnetic resonance (NMR), 13 C NMR and mass spectrometry.…”

Sources of C20-polyunsaturated fatty acids for biotechnological use

“…Johns et al (1979) investigated the fatty acids of ten marine algae including green, red and brown representatives, and concluded that hexadecatetraenoic acid (16:4 o93) could be taxonomically distinguishing for species of Chlorophyta. Table 1 presents arachidonic and eicosapentaenoic acid contents of representative brown and red macroalgae (see also Rezanka et al 1988;Pettitt et al 1989a). In the few macroalgae studied so far, C20-polyunsaturated fatty acids were found mainly associated with polar lipids, viz.…”

Comprehensive thin layer chromatography×gas chromatography using headspace sampling modulation—A case study on fatty acid composition analysis

“…A two-dimensional TLC-GC approach has been performed several times up to date, not surprisingly, mostly for the analysis of lipids [23][24][25][26][27][28], since TLC can provide a selective separation of different lipid classes. Unfortunately, only a few of the existing approaches has been automated, at least to some degree.…”
