High-resolution 1H NMR spectroscopy of aqueous humour from rabbits
1MR Center, SINTEF UNIMED, Trondheim, Norway.
Background:
Detection of different substances in aqueous humour is important for evaluation of the disorders affecting the eye. The purpose of the present study was to apply high-resolution proton (1H) nuclear magnetic resonance (NMR) spectroscopy for extensive characterisation of the metabolites in the aqueous humour from rabbits.
Methods:
High-resolution 1H NMR spectroscopy, including two-dimensional shift correlated (COSY) technique, was performed on aqueous humour from rabbits.
Results:
More than 20 metabolites were simultaneously detected and identified in high-resolution 1H NMR spectra of aqueous humour from rabbits. Some of these were also quantified.
Conclusion:
High-resolution 1H NMR spectroscopy is a valuable method for simultaneous detection of many different metabolites in aqueous humour.
