RP-HPTLC method for determination of Voriconazole in bulk and in cream formulation

Voriconazole is used as an antifungal agent. A new rapid, simple, economical and environmental friendly Reversed -Phase High-Performance Thin-Layer Chromatography (RP-HPTLC) has been developed and validated for quantitative determination of voriconazole in bulk and in cream formulation. RP-HPTLC separation was performed on aluminium plates precoated with silica gel 60RP-18F-254S as the stationary phase using Acetonitrile: Water (60:40% v/v) as mobile phase. Quantification was achieved by densitometric analysis at 257 nm over the concentration range of 200-1200 ng/band. The method was found to give compact and well resolved band for Voriconazole at Retention factor (Rf) 0.48 ± 0.02. The linear regression analysis data for calibration graph showed good linear relationship with r2 = 0.999. The method was validated for precision, recovery, robustness, ruggedness and sensitivity as per International conference on Harmonization (ICH) guidelines. The Limit of Detection (LOD) and Limit of Quantification (LOQ) were found to be 19.99 ng and 60.60 ng, respectively. The proposed developed RP-HPTLC method can be applied for identification and quantitative determination of Voriconazole in bulk and in cream formulation.
