Abstract
A novel sample clean-up procedure for the determination of free 3-methoxy-4-hydroxyphenylglycol (MHPG) in plasma is described. MHPG was purified with Sep-Pak alumina B cartridge followed by ethyl acetate extraction from the Cartridge. High-performance liquid chromatography with amperometric detection was used for separation and detection of MHPG and the internal standard 3-ethoxy-4-hydroxyphenylglycol (EHPG). This method provided good, clean chromatograms with base-line separation of the appropriate peaks. This technique is sensitive, reliable and less time-consuming than other methods. Thus, only 0.5 ml of plasma is needed and.
