Identification of arachidonate epoxides/diols by capillary chromatography-mass spectrometry.

open access: yesJournal of Lipid Research, 1995
The identification of epoxide regioisomers of arachidonic acid (EETs) as methyl esters is difficult because they coelute during gas chromatography and possess similar mass spectra.

Isolation and characterization of a novel uronic acid-containing acidic glycosphingolipid from the ascidian Halocynthia roretzi

open access: yesJournal of Lipid Research, 2007
A novel uronic acid-containing glycosphingolipid (UGL-1) was isolated from the ascidian Halocynthia roretzi. UGL-1 was prepared from chloroform-methanol extracts and purified by the use of successive column chromatography on DEAE-Sephadex, Florisil, and ...
