In order to study the hydrolytic characterization of an and-inflammatory prodrug(RI-1) m vitro,an effective,accurate and reliable method for the simultaneous determination of the prodrug and itS two hydrolytic active compounds is developed using reverse phase high-performance liquid chromatography (RP-HPLC).The chromatographic separation is performed on an ODS-2 C18,column(250 mm×4.6 mm,5.0 μm particle size)with a simple elution program.The mobile phase is V(methanol):V(0.1%phosphoric acid solution)=90:10(adjust pH to 2.3).A wavelength of 225 nm and a mobile phase flow rate of 1.0mL/min are utilized for the quantitative analysis.Excellent linear behaviors over the investigated concentration ranges are observed with values of R2 higher than 0.999 for all the analytes.The validated method is successfully applied to the simultaneous determination of the prodrug and its active components can be used to detect hydrolytic characterization in vitro.
