Figure 1. Chromatographic separation of miconazole dissolved in saliva or PBS.
Miconazole, dissolved in 10% human saliva or PBS, was isolated on a C-18 HPLC column as described in the Methods section. Panel A: Chromatogram of 0.2 µg/mL miconazole dissolved in 10% saliva. Miconazole elutes at 6.7 mins and the area under the curve (proportional to concentration) is shown in the box and calculated by the HPLC. Panel B: Chromatogram of 0.2 µg/ml miconazole dissolved in PBS. Miconazole elutes in an equivalent manner as found in Panel A. Panel C: A representative standard curve for miconazole dissolved in 10% saliva. Each point represents the mean±SEM for 5 determinations. Irrespective of the solvent used, dose-dependency and linearity were equivalent to that shown.
