BACKGROUND: Combination of betamethasone valerate and neomycin sulfate in cream is used to treat the itching, redness, dryness, scaling, inflammation and discomfort of various skin conditions caused by infection. The combination of active ingredients has side effects which can cause dry skin, thinning of the skin, hypertrichosis, and stretch marks. AIM: The purpose of this study was to make a formula containing vitamin E and quantitative analysis of betamethasone valerate and neomycin sulfate in creams using High Performance Liquid Chromatography and Spectrophotometry Area Under Curve methods. METHODS: Cream preparation includes smelting and emulsification processes, with oil phases namely stearic acid and vitamin E as well as water phases are glycerin, sodium bi-borate, tri-ethanolamine. Physical tests for the cream were organoleptic, homogeneity, pH, evaluation of dispersion, and viscosity. HPLC analysis for cream was carried out using C18 column, and the mobile phase of methanol: water with comparison optimization beforehand. Spectrophotometry analysis for cream was carried out using application of Area Under Curves methods. RESULTS: The formula used was betamethasone valerate 5 mg, neomycin sulfate 25 mg, stearic acid, glycerin, sodium bi-borate, tri-ethanolamine, vitamin E and distilled water. The obtained cream was in the form of semi-solid, odorless, white (colorless), homogeneous, pH 7, the dispersion power of 500 mg cream is 4.0-4.3 cm in diameter and viscosity is 7500 Cps. Analysis of the determination of the levels of the two components was carried out by the HPLC method C-18 column with the mobile phase of methanol: water (90: 10). Betamethasone valerate and neomycin sulfate levels in formulas made HPLC methods were 94.15%, and 136.56%, respectively and using AUC spectrophotometry methods were 107.98% and 94.81%. CONCLUSION: Cream that made by new formula with vitamin E shows good result in physical evaluation. HPLC methods with a mobile phase of methanol: water (90:10) was not recommended, while the AUC spectrophotometry method shows the valid result of quantitative analysis of betamethasone valerate and neomycin sulfate in cream.

Abstract A reliable and sensitive HPLC method was developed for the quantitation of tadalafil transdermal permeation through human skin. An RP column with UV detection at 290 nm was used for chromatographic separation at ambient temperature. The mobile phase was acetonitrile–water containing 20 mM pH 7 phosphate buffer (35/65, v/v) with a flow rate of 1.0 mL/min. The LOQ achieved was 1 ng/mL, and the calibration curve showed good linearity over the concentration range of 5–2000 ng/mL for tadalafil, with a determination coefficient (R2) of 0.998. The RSD values of intraday and interday analyses were all within 7%. Parameters of validation proved the precision of the method; this validated method was applied for the determination of tadalafil in transdermal permeation and drug deposition in human skin studies.

Using the high performance liquid chromatography (HPLC) method, bifenthrin isomers can be split at a polysaccharide derivatives chiral stationary phase column, and two well distinguished peaks of bifenthrin isomers are obtained. The effects of mobile phase ratios, temperatures, and detection wavelengths on the separation results are discussed. The optimal chromatographic conditions are as follows: the mobile phase ratio is methanol: ammonium acetate salts = 80:20, the column temperature is 35°C, and the wavelength is set as 220 nm. Under the optimal conditions, the resolution of bifenthrin enantiomer can be as large as 3.0.

This study presents an HPLC method for simultaneous analysis of astaxanthin and its carotenoid precursors from Xanthophyllomyces dendrorhous. The HPLC method is accomplished by employing a C18 column and the mobile phase methanol/water/acetonitrile/ dichloromethane (70:4:13:13, v/v/v/v). Astaxanthin is quantified by detection at 480 nm. The carotenoid precursors are identified by LC-APCI-MS and UV-vis absorption spectra. Peaks showed in the HPLC chromatogram are identified as carotenoids in the monocyclic biosynthetic pathway or their derivatives. In the monocyclic carotenoid pathway, 3,3’-dihydroxy- β,ψ-carotene-4,4’-dione (DCD) is produced through γ-carotene and torulene.

The goal of the current study was to establish and authenticate an isocratic reverse-stage High-Performance Liquid Chromatography (HPLC) method for quantifying ketotifen fumarate (KF) in pharmaceutical liquid dosage compositions. Easy, quick, accurate, exact, and accurate reverse-stage high-performance liquid chromatography was advanced for the simultaneous assessment of ketotifen fumarate in the liquid syrup dosage type. The HPLC system using isocratic elution method with reverse-phase Inertsil ODS-(250 mm × 4.6 mm, 3 μm) column was detected by ultraviolet absorbance at 297 nm with no interference from widely using excipients, the mobile phase (A) is a mixture of triethylamine and water (175 μl in 500 ml of water), and the mobile phase (B) is a mixture of triethylamine and methanol (175 μl in 500 ml of methanol) at a flow rate of 1.5 mL/min (mobile phase A 40 %:mobile phase B 60%) at column temperature using 40 ° C, the retention time for ketotifen fumarate was 6.4±0.5 min. The concentration curves were linear in the range of 10.0 to 35.0 μg / ml (R2 = 0.9999). The developed method was tested for the specificity, precision, linearity, precision, reliability, robustness, and consistency of the solution. The regeneration of ketotifen fumarate in formulations was found to be 99.75 %, 99.91 %, and 100.05 % respectively. The percent RSD for percent recovery was found to be 0.21 and 0.17 and 0.10 for ketotifen fumarate. In the conclusion, the suggested technique was successfully used for the quantitative determination of ketotifen fumarate in formulations.

The present work demonstrates a simple, rapid, precise, specific, and sensitive reverse-phase high-performance liquid chromatography (RP-HPLC) method for analyzing glimepiride in pure and tablet forms. The present method was developed using a C18 column 150 × 4.6 mm, with 5 μm, and packing L1 maintained at a temperature of 30°C. The mobile phase was prepared by dissolving 0.5 gram of monobasic sodium phosphate in 500 mL of distilled water, pH of the solution adjusted to 2.1 to 2.7 with 10% phosphoric acid, and added 500 mL of acetonitrile. The mobile phase was pumped in the highperformance liquid chromatography (HPLC) system at a flow rate of 1 mL/min, and separation was carried out at 228 nm, using an ultraviolet (UV) detector. The chromatographic separation was achieved with peak retention time (RT) at about 9.30 minutes, and the method was found to be linear over a concentration range of 40 to 140 μg/mL. The specificity of the method represented no interference of the excipients during the analysis, and stability testing after 24 hours also showed that the method is suitable and specific. The accuracy was between 99.93 to 99.96%, with limit of detection (LOD) and limit of quantitation (LOQ) being 0.354 μg/mL, 1.18 μg/mL, respectively. Satisfactory results were found for precision and robustness parameters during the development and validation stage for the analytical method. The proposed method was also adopted for the analysis of glimepiride tablets to improve the overall quality control. Using this method, symmetric peak shape was obtained with reasonable retention time. The retention time of glimepiride for six repetitions is 9.3 ± 0.1 minutes; the run time is 21 minutes. The proposed RP-HPLC method is a modification of the United States Pharmacopeia (USP) method, and it was found to be valid for glimepiride within concentration ranges 40 to 140 μg/mL, using C18 analytical columns, and isocratic elution with UV detection, and at 1 mL/min of flow rate.

A research about a comparative study of spectrophotometry UV-Vis and HPLC method for the analysis of vitamin E in saponified red palm oil has been done. This research aims to compare the results of analysis using Spectrophotometer UV - Vis and HPLC to determine the concentration of vitamin E in red palm oil previously saponified and extracted. HPLC analysis was carried out using an RP-18 column and mobile phase composed a methanol and water ( 86:14 ), with a flow rate of 1 ml/min and UV detection at 290 nm. For the Spectrophotometric UV-Vis analysis, hexane was used as a solvent and the wavelength at 298,5 nm was selected for the detection. The results are the concentration of vitamin E using spectrophotometric and HPLC method was respectively 104.5 ppm and 127 ppm.Keyword: Vitamin E, Red Palm Oil, saponification, extraction, spectrophotometry Ultra Violet -Visible, High Performance Liquid Chromatography
