Fluorescence detected magnetic resonance detection-identification

The individual separation, identification, and quantification of OL derivatives from natural extracts have been realized basically by chromatographic separation or capillary electrophoresis methods. Both gas and liquid chromatographies have been exploited, combined with several detection methods such as UV, fluorescence, and mass spectrometry (MS) [14], Soft spectroscopic techniques as midium infrared spectroscopy have been recently explored for rapid quantification of OL [61], while high-resolution spectroscopic techniques as nuclear magnetic resonance are considered interesting applicatimi in the analysis of the OL derivative structures [14].
