Correlation between retention behaviour and GC-FTIR data in the study of flavonoids.
Trimethylsilyl derivatives of 10 different hydroxy- and methoxyhydroxyflavonoid compounds were studied by the GC-FTIR technique. Optimal deviation parameters were determined for the flavonoids studied. The correlation found between retention and gas-phase IR data can successfully be used in structural identification of compounds having very similar chromatographic behaviour. The shift of the carbonyl frequency gives information on the presence of substituting agents.
