A rapid, simple and validated reversed-phase high-performance liquid chromatographic method has been developed for analysis of aripiprazole in tablet dosage form. Aripiprazole was separated on an ODS analytical column with a 40:60 (v/v) mixture of acetonitrile and triethanolamine buffer (5 mM, pH 3.5 ± 0.05 adjusted by addition of 85% phosphoric acid) as mobile phase at a flow rate of 1.5 mL min-1. The effluent was monitored by UV detection at 254 nm. Calibration plots were linear in the range of 20 to 60 µg mL-1and the LOD and LOQ were 0.411 and 1.248 µg mL-1, respectively. The high recovery and low relative standard deviation confirm the suitability of the method for routine quality control determination of aripiprazole in tablets.

Tea tree oil, an active ingredient of skin, hair and nail care cosmeceuticals, has claims for topical antimicrobial, analgesic and anti-inflammatory activity. Its complex composition is governed by ISO 4730:2017. Terpinene-4-ol is the principal constituent of the oil (35% - 48%) followed by γ-terpinene (14% -28%), α-terpinene (6%-12%) and 1,8-cineole (≤15%). A reversed-phase, isocratic high performance liquid chromatographic method has been developed and validated for routine determination of tea tree oil based on1,8-cineole content in bulk and commercially available cosmeceuticals using C18 column, methanol-water (70:30 v/v) as mobile phase and flow rate of 1mL/min. UV detection was done at 200 nm. Linearity of the method was established for 20-100μL/mL (R2 = 0.9992) with LOD, LOQ values of 0.5594 μL/mL and 5.5941μL/mL respectively. The % RSD values for robustness and precision were <1% and recovery ranged between 99.09-102.96%. The method was successfully applied for determination of 1,8-cineole content in cosmeceuticals.

Abstract A rapid, accurate, and sensitive high-performance liquid chromatographic (HPLC) method was developed and validated for the determination of ceftazidime in pharmaceuticals. The method validation parameters yielded good results and included range, linearity, precision, accuracy, specificity, and recovery. The excipients in the commercial powder for injection did not interfere with the assay. Reversed-phase chromatography was used for the HPLC separation on a Waters C18 (WAT 054275; Milford, MA) column with methanolwater (70 + 30, v/v) as the mobile phase pumped isocratically at a flow rate of 1.0 mL/min. The effluent was monitored at 245 nm. The calibration graph for ceftazidime was linear from 50.0 to 300.0 g/mL. The values for interday and intraday precision (relative standard deviation) were &lt;1. The results obtained by the HPLC method were calculated statistically by analysis of variance. We concluded that the HPLC method is satisfactory for the determination of ceftazidime in the raw material and pharmaceuticals.

Highly nutritious dairy products are ingested regularly by all ages of population. Adulteration of dairy products to enhance the inherent stability and acceptability to common consumers by different harmful and toxic ingredients like formalin, an unpermitted preservative, has been a burning issue in Bangladesh over the last few years. The aim of this paper was to analyze the concentration of formaldehyde in dairy products most commonly sold in Bangladeshi markets by a validated reversed phase high performance liquid chromatographic (RP-HPLC) method to reveal the on-going alarming scenario in a scientific way. After pre-derivatization with 2,4- dinitrophenylhydrazine, formaldehyde was detected at 345 nm using a C18 column with acetonitrile and water (45:55) as mobile phase at a flow rate of 2.0ml/min. The validated method has been applied to 41 marketed dairy products, including pasteurized milk, UHT milk, banana- mango- and chocolate-milk, flavored yoghurt, lassi, buttermilk, and skimmed milk. However, no formaldehyde was detected among the tested dairy products.Dhaka Univ. J. Pharm. Sci. 15(2): 187-194, 2016 (December)

A high performance liquid chromatographic method for determination of rifabutin in human plasma was  developed. The method involved deproteinisation of the sample with acetonitrile and analysis of the  supernatant using a reversed-phase C18 column (250mm) and UV detection at a wavelength of 265nm.  The assay was specific for rifabutin and linear from 0.025 to 10.0μg/ml. The relative standard deviation  of intra- and inter-day assays was lower than 10%. The method was able to remove interfering materials  in plasma, yielding an average recovery of rifabutin from plasma of 101%. Due to its simplicity, the assay  can be used for pharmacokinetic studies of rifabutin.

A simple, selective, linear, precise and accurate isocratic RP-HPLC method was developed and validated for rapid assay of Vandetanib, an anticancer drug, in both bulk and tablet dosage form. Elution at a flow rate of 1ml/min was employed on a symmetry C18 column at ambient temperature. The mobile phase consisted of acetonitrile, water and orthophosphoric acid in the ratio of 90:08:02 (v/v/v). Linearity was observed in concentration range of 50-200 ppm. The retention time for Vandetanib was 3.326 min. The method was validated as per the ICH guidelines. The proposed method can be successfully applied for the estimation of Vandetanib in pharmaceutical dosage forms. Moreover the detection alone was also verified through LC-MS of the Vandetanib drug using ESI method which provides future scope for study of this drug using LC-MS method also.

A reversed-phase high-performance liquid chromatographic (HPLC) method was developed and validated for the determination of encapsulation efficiency of zidovudine in nanoparticules. The method was carried out in isocratic mode using 0.040M sodium acetate: methanol: acetonitrile: glacial acetic acid (880:100:20:2) as mobile phase, a C8 column at 25ºC and UV detection at 240 nm. The method was linear (r2 ˃ 0.99) over the range of 25.0-150.0 μg/mL, precise (RSD ˂ 5%), accurate (recovery = 100.5%), robust and selective. The validated HPLC-UV method can be successfully applied to determine the rate of zidovudine in nanoparticules.

A reversed phase high performance liquid chromatographic (RP–HPLC) method was developed and subsequently validated for the determination of atomoxetine hydrochloride in bulk and pharmaceutical formulation. The separation was done by a PerkinElmer Brownlee analytical C8 column (260 mm x 4.6 mm, 5 µm) using methanol: 50 mM KH2PO2buffer (PH adjusted to 6.8 with 0.1 M NaOH), 80:20 v/v as an eluent. UV detection was performed at 270 nm at a flow rate 1.0 mL/min. The validation of the method was performed, and specificity, reproducibility, precision accuracy and ruggedness were confirmed. The correlation coefficient was found to be 0.997 for atomoxetine hydrochloride. The recovery was in the range of 99.94 to 100.98% and limit of quantification was found to be 5.707 µg/mL. The method is simple, rapid, selective and economical too and can be used for the routine analysis of drug in pharmaceutical formulations.

A simple, sensitive and precise high performance liquid chromatographic method for the analysis of pantoprazole sodium and lansoprazole has been developed, validated and used for the determination of compounds in commercial pharmaceutical products. The compounds were well separated an isocratically on a C18column [Inertsil C18, 5μ, 150 mm x 4.6 mm] utilizing a mobile phase consisting of acetonitrile: phosphate buffer (60:40, v/v, pH 7.0) at a flow rate of 1.0 mL/min with UV detection at 230 nm. The retention time of pantoprazole sodium and lansoprazole was found to be 2.017 min and 2.538. The procedure was validated for linearity (Correlation coefficient=0.999). The study showed that reversed-phase liquid chromatography is sensitive and selective for the determination of pantoprazole sodium and lansoprazole using single mobile phase.
