Clobetasol 17-propionate is used most potent topical glucocorticoid clinical effective in treatment of topical dermatitis, vitiligo and psoriasis. A rapid, simple, selective and precise UV- Visible Spectrophotometric method has been developed for the determination of Clobetasol 17-Propionate (CP) in bulk forms and dosage formulations. The spectrophotometric detection was carried out at an absorption maximum of 239 nm using ethanol as solvent. The method was validated for specificity, linearity, accuracy, precision, and robustness. The detector response for the CP was linear over the selected concentration range 2 to 40μg/ml with a correlation coefficient of 0.9999. The accuracy was between 99.1 and 101.4 %. The precision of 4μg/ml sample preparation three times in a day (intraday) was 0.1325%. The Limit of Detection (LOD) and Limit of Quantification (LOQ) are 0.84 and 2.55μg/ml, respectively. The recovery of CP was about 101.84%. The results demonstrated that the excipients in the commercial formulation did not interfere with the method and can be conveniently employed for daily routine quality control analysis of CP in bulk drug, marketed formulations.

A simple and sensitive ultraviolet spectrophotometric method for quantitative estimation of glipizide in presence of lipid turbidity is described to avoid false estimation due to diffraction by turbidity. UV detection was performed at 230 nm, 225 nm, and 235 nm, and the calibration curve was plotted between resultant of absorbance of [230 nm − (225 nm + 235 nm)/2] and concentration of analyte. The calibration curve was linear over the concentration range tested (1–20 μg/mL) with limit of detection of 0.27 μg/mL and limit of quantification of 0.82 μg/mL. Percent relative standard deviations and percent relative mean error, representing precision and accuracy, respectively, for clear as well as turbid solutions, were found to be within acceptable limits, that is, always less than 0.69 and 0.41, respectively, for clear solution and 0.65 and 0.47, respectively, for turbid solution. Conclusively, our method was successfully applied for the determination of glipizide in clear as well as turbid solutions, and it was found that the drug analyte in both types of solutions can be detected from the same calibration curve accurately and precisely and glipizide entrapped in the liposomes or in proliposomal matrix was not detected.

Acrylamide is a potential health hazardous compound occurring in baked and fried food as a result of excessive dry heating during the preparation and/or processing of foods. Exposure to a high level of acrylamide may cause cancer, neurotoxicity, and mutagenicity. In this study, an isocratic reversed-phase high-performance liquid chromatographic (HPLC) method using a C18 column was used for the determination of acrylamide in selected food. The mobile phase consisted of 0.1% formic acid in water: acetonitrile (98:02), and the flow rate was 1.0 mL min-1, elution was monitored at 200 nm. Validation in selected conditions showed that the chosen method is sensitive, selective, precise, and reproducible with a linear detector response for the determination of acrylamide. The limit of detection (LOD), and the limit of quantification (LOQ), were achieved at 0.41μg mL-1 and 1.25 μg mL-1respectively. The proposed method was also applied after validation to the most popular six brands of chips and French fries available in the Libyan market. Acrylamide was extracted by a simplified extraction method avoiding cleanup by solid-phase extraction (SPE), then analyzed by HPLC-UV. The highest level of acrylamide was found in one brand of chips with a concentration of 16.33 μg mL-1, whereas only one of the French fries products analyzed exhibited an acrylamide concentration of 10.26 μg mL-1.
