摘要

The presence of free fatty acid (FFA) in unbuffered solution containing 2-methyl-l,4-naphtoquinone (VK3) causes a prepeak of the quinone reduction wave on the voltammogram, and the prepeak height is increased with the FFA concentration. Based on this catalytic prepeak, we previously developed a new HPLC with electrochemical detection (HPLC-ECD) using VK3 for determining plasma FFAs. In the previous paper [1], we reported the monitoring plasma FFA with blood glucose level before and after meal ingestion. It has been interesting to clearify the relation between FFAs and valproic acid (VA), a drug for seizures and acute psychotic mania. In this study, the HPLC-ECD system has been improved in terms of sensitivity and separation of each FFAs and of VA by a C30 microbore column and 3,5-di-t-butyl-l,2-benzoquinone (DBBQ) as the quinone reagent, and the determination of plasma FFAs and VA in normal and diabetic rats was carried out using the present method.
