Figure 1From: CYP450 phenotyping and metabolite identification of quinine by accurate mass UPLC-MS analysis: a possible metabolic link to blackwater feverMSEidentification of quinine quinuclidine ring metabolites. Shown in panels A-D are the corresponding MSE spectra (i) for quinine and each quinine quinuclidine ring metabolite. The m/z values for each ion are indicated as well as the assigned quinine fragment. The assigned metabolite structures are shown in (ii). The observed parent ion m/z, mass error, and CYPs responsible for production of each metabolite are indicated under each structure.Back to article page
