Aim: To develop new selective and sensitive reverse-phase high-performance liquid chromatography (RP-HPLC) approach for the quantification of antifungal drug Luliconazole integrate with corticosteroid drug Clobetasol Propionate in a synthetic mixture. Methods: The method was validated to achieve International Conference Harmonization (ICH) requirements. Chromatographic separation was carried out by isocratic technique on a reversed-phase Inertsil C18 column (5 µm, 250mm x 4.6mm i.d with the mixture of Acetonitrile: Water pH adjusted with H3PO4 (60: 40) and UV detection at 264 nm. The compounds were eluted at a flow rate of 1.0 mL/min with an injection volume of 20μL. Results: The calibration curves were linear (r2 > 0.999) over the concentration range 10-200 μg/mLfor Luliconazole and 5-100 μg/mL for Clobetasol Propionate. The average retention times for Luliconazole and Clobetasol Propionate were 3.16 and 6.94 min, respectively. The % RSD   for the proposed method was found to be less than %2. The % recovery was found to between 99.22-99.48% for the developed method. Conclusion: The developed method is simple, rapid, precise, and accurate and hence was successfully applied for the determination of Luliconazole and Clobetasol Propionate in a synthetic mixture.

Satranidazole is a new nitroimidazole derivative with potent antiamoebic action and is available in market in the form of tablet and dry syrup either alone or in combination with Ofloxacin. The present study involves the development of simple, accurate, precise, and reproducible reversed phase high performance liquid chromatography (RP-HPLC) method for determination of Satranidazole from its granular dosage form. Isocratic elution at a flow rate of 1.0 mL/min was employed on BDS Hypersil C18 (250 mm × 4.6 mm, 5 μm) column at 25°C temperature. The mobile phase consists of 0.16% v/v orthophosphoric acid solution, pH 3: acetonitrile in the ratio of 60 : 40 v/v. The UV detection wavelength was 320 nm, and 20 μL sample was injected. The retention time for Satranidazole was about 4.3 minutes. The method was validated for various parameters such as system suitability, precision, recovery, robustness, and ruggedness as per ICH guidelines. The validated RP-HPLC method was found to be specific, linear, precise, and accurate and can be successfully employed for the assay of Satranidazole taste masked granules coated with Eudragit E100 and marketed tablets.

Abstract The aim of the study was to develop a rapid, efficient, and cheap chromatographic method for determining four selected antihypertensive active flavonoid compounds in medicinal plants in Botswana. The determination of rutin, quercetin, and kaempferol in selected medicinal plants was conducted in less than 6 min using the developed reverse phase-high performance liquid chromatography (RP-HPLC) method with a 2.7 µm Ascentis C18 express column (150 × 4.60 mm i.d) at 340, 360, and 368 nm detection wavelengths and mobile phase of methanol and 0.068% of formic acid solution in isocratic elution. Validation results showed good selectivity, linearity (r 2 > 0.99), high percentage recoveries (90.2–104.7%), and precision (% RSD < 2) for n = 3, confirming suitability of the method for determination of the investigated flavonoids in Zingiber officinale (ginger). Application of the developed RP-HPLC method was performed in selected medicinal plants (Lippia javanica ) (mosukujane), Myrothanmus flabellious (galalatshwene), and Elephantorrhiza elephantina (mositsana) used to manage hypertension by herbalists in Botswana. M. flabellious a very commonly used plant for managing hypertension was found to contain highest amounts of rutin and myricetin, whereas nothing was detected for E. elephantina.
