Chromatography of microbial metabolites of aromatic amino acids.


A mixture of hydroxy-, methoxy- and aminobenzenecarboxylic acids (aromatic acids) was studied by gas (GC) and liquid (LC) chromatography. The gas and high-performance liquid chromatographs were attached to a computer. The GC method yielded elution data for trimethylsilyl derivatives of a large number of aromatic acids on four stationary silicone phases, OV… (More)
