Abstract

A simple and rapid HPLC method with fluorescence detection(FLD) for quantitation of penciclovir in human plasma using a monolithic column was developed and validated. Penciclovir and ganciclovir(internal standard, I.S.) were separated on a Chromolith column RP-18e (<TEX>$4.6{\times}100mm$</TEX>) with a mobile phase consisting of a mixture of (A) methanol/50 mM sodium phosphate buffer containing 200 mg/L sodium dodecyl sulfate (3/97, pH 2.5) and (B) methanol/50 mM sodium phosphate buffer containing 200 mg/L sodium dodecyl sulfate (50/50, pH 2.5) at a flow gradient of <TEX>$1.6{\sim}4.0mL/min$</TEX>. The retention times of penciclovir and internal standard were less than 4.0 min. Calibration curve was linear (<TEX>$R^2
