2. Mass Spectrometry of Biologically Active Small Molecules : Focusing on polyphenols, alkaloids and amino acids
Abstract : The foci of this dissertation are on advanced liquid chromatography (LC) separation and mass spectrometry (MS) techniques for the analysis of small bioactive molecules. In addition to discussing general aspects of such techniques the results from analyses of polyphenols (PPs), alkaloids and amino acids published in five appended studies are presented and discussed.
