Distribution of fatty acids in triacylglycerols from ungrafted Desi Mango (Mangifera indica) kernel lipids

Journal of Saudi Chemical Society, 2010
The lipids of ungrafted ‘Desi’ mango (Mangifera indica) kernel were extracted with chloroform/methanol, purified and triacylglycerols (82.6%) were separated by thin layer chromatography (TLC). The pure triglycerides are fractionated into five bands by 25%

Chemiluminescence detection of gangliosides by thin-layer chromatography.

Journal of Lipid Research, 1995
We describe a method for the detection of gangliosides on thin-layer chromatography plates using enhanced chemiluminescence. In contrast to previously published colorimetric techniques, the use of chemiluminescence of detect antibody binding to ...

Preparative thin-layer and column chromatography of prostaglandins

Journal of Lipid Research, 1969
Analytical and preparative chromatographic methods for monounsaturated prostaglandins are described. The systems were developed specifically for separation of the various hydroxy epimers of prostaglandin E1 and F1 but also offer superior separations for ...

Oxalate-silica gel thin-layer system for free 2-hydroxy fatty acids and for fatty acyl coenzyme A

Journal of Lipid Research, 1972
The 2-hydroxy fatty acids tend to yield streaks in thin-layer chromatography on silica gel plates. If potassium oxalate is included with binder-free silica gel, good spots are obtained.

Synthesis of fibroin/silica adsorbent for thin layer chromatography

Хімія, фізика та технологія поверхні
The main aim of this work is to synthesize microspherical fibroin/silica adsorbent through a one-step in situ synthesis that integrates silk fibroin into the hydrolytic polycondensation of tetraethoxysilane (TEOS). The kinetics of the sol-gel process is

Thin-layer chromatography of tissue lipids without extraction

Journal of Lipid Research, 1970
Frozen tissue sections were applied directly to silica gel plates, and the lipids were separated by developing the plates in different solvent systems.

Co-57-based intercomparison of TLC scanners and dose calibrators for low-activity radiochemical purity assessment in radiopharmaceutical quality control

EJNMMI Radiopharmacy and Chemistry
Background Thin layer chromatography scanners and dose calibrators are commonly used to assess radiochemical purity of radiopharmaceutical preparations. Strict quality assurance programs surveyed by regulatory bodies exist for dose calibrators, but they ...
