General protocol for NMR Analysis of Unknown Compounds or Metabolites

7 GENERAL PROTOCOL FOR NMR ANALYSIS OF UNKNOWN COMPOUNDS OR METABOLITES [Pg.389]

The application of NMR for the analysis of metabolite structures is a multi-step process that is fundamentally based on spectral comparisons. The first step [Pg.389]

HPLC system connected to the NMR flow probe (30-120 pi) via a UV detector. Experiments can be performed in on-flow, stop-flow, and loop collection modes [Pg.390]

DAD UV detector used for peak detectionRegular reversed-phase Cl8 (4.6 x 150 mm) columns [Pg.390]

CHjCN or CHjOHiHjO with trifloroacetic acid or formic acid as a modifier. [Pg.390]
