Abstract
Official abstract text for this publication.
[Problem] To provide a method of scavenging an unstable radical derived from a lipid and analyzing structures of those radicals.[Means for solution] A fluorescent nitroxide (NBD-Pen) is made to act to scavenge a lipid radical or a fragment radical thereof, and fluorescent detection liquid chromatography (LC/FL) and mass spectrometry (MS) are combined to identify lipid-derived radicals contained in a lipid extract.
