Representative HPLC Chromatograms for (A) a standard buffer solution spiked with griseofulvin (500 ng/mL) and the IS (warfarin; 50 μg/mL); (B) blank rat plasma; (C) blank rat plasma spiked with griseofulvin (500 ng/mL) and the IS (50 μg/mL); (D) rat plasma sample obtained 5 hr after a 50 mg/kg oral dose of griseofulvin; (E) Limit of detection (LOD) of griseofulvin in rat plasma: 1 ng/mL; and (F) Limit of quantification (LOQ) of griseofulvin in rat plasma: 10 ng/mL. Peak 1 = griseofulvin and Peak 2 = IS.
