High Pressure Liquid Chromatography of Eicosanoids

1985
Arachidonic acid (20:4) and other polyunsaturated fatty acids can be oxygenated in many tissues by cyclooxygenase or a variety of lipoxygenases. The intermediates formed in these reactions are then converted enzymatically to a variety of other products.

Analysis of vitamin A in eggs by high pressure liquid chromatography

Food / Nahrung, 1991
AbstractA high speed liquid chromatographic method was described for the rapid determination of vitamin A in eggs. After saponification and extraction, the sample was separated on a reversed‐phase column (C18) with acetonitrile ‐ methylene‐chloride ‐ methanol as the mobile phase. Quantitative determination was accomplished by monitoring the ultraviolet

ChemInform Abstract: LIQUID‐LIQUID PARTITION COEFFICIENTS BY HIGH‐PRESSURE LIQUID CHROMATOGRAPHY

Chemischer Informationsdienst, 1975
Lipid-water partition values can be rapidly and reliably measured by high-pressure liquid chromatography (HPLC) on bonded octadecylsialne supports. This method has been developed and applied to a family of hypotensive triaminopyrimidine 3-oxides. The measured column retention values for this class of compounds correlate well with the values calculated ...
