The article presents the results of the research on the development of the procedure for determining related impurities by high-performance reversed-phase chromatography in the tablets “Ranolazin-NAN”. The conditions for samples preparation of ranolazine tablets, optimal conditions for the gradient mode of chromatography were selected using Zorbax Eclipse Plus C18 column: eluent A - 0,1% triethylamine buffer with pH 6,0 ± 0,1 (diluted with orthophosphoric acid) and acetonitrile in a ratio 70:30 v / v and eluent B - acetonitrile. The effect of pH medium (2,0, 6,0 and 9,0) on the efficiency of the column while studying the solutions of ranolazine and identified impurities was established. The suitability of the chromatographic system was proven and the specificity of the method for determining unidentified and identified impurities was proven. Linearity in the entire range of the procedure usage (from the quantitation limit to 125% (of the content of a single impurity)), correctness as well as precision at the level of reproductivity and intermediate precision, and the stability (robustness) of the method with small changes in the flow rate and column temperature were proven for the procedure of related impurities determination in Ranolazin-NAN 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 Atorvastatin calcium is a synthetic HMGCoA reductase inhibitor that is used as a cholesterol-lowering agent. A simple, sensitive, selective, and precise RP-HPTLCdensitometric determination of atorvastatin calcium both as bulk drug and from pharmaceutical formulation was developed and validated according to International Conference on Harmonization guidelines. The method used aluminum sheets precoated with silica gel 60 RP18F254s as the stationary phase, and the mobile phase consisted of methanolwater (3.5 + 1.5, v/v). The system gave a compact band for atorvastatin calcium with an Rf value of 0.62 0.02. Densitometric quantification was carried out at 246 nm. The linear regression analysis data for the calibration plots showed a good linear relationship with r = 0.9992 in the working concentration range of 100-800 ng/band. The method was validated for precision, accuracy, ruggedness, robustness, specificity, recovery, LOD, and LOQ. The LOD and LOQ were 6 and 18 ng, respectively. The drug underwent hydrolysis when subjected to acidic conditions and was found to be stable under alkali, oxidation, dry heat, and photodegradation conditions. Statistical analysis proved that the developed RP-HPTLCdensitometry method is reproducible and selective and that it can be applied for identification and quantitative determination of atorvastatin calcium in bulk drug and tablet formulation.

Abstract An HPTLC method with densitometric quantification using fluorescence at 313 nm was developed and validated for the determination of ofloxacin residue in controlling pharmaceutical equipment cleanliness. Simulated samples at a residue level of 1 mg/m2 were prepared by spreading the calculated amount of ofloxacin solution on 1, 5, and 10 dm2 stainless steel surfaces. After evaporation of the solvent, the residue was removed by two ethanol wetted cotton swabs, which were thereafter extracted with the mixture of ethanol and Na2EDTA–water solution at pH 11 for 15 min with sonication. The extract and standards were applied on HPTLC silica gel 60 plates and then developed in a horizontal developing chamber from both sides using ethanol-conc. ammonia (4 + 1, v/v) as the mobile phase. The mean recovery (n = 6) at 1 mg/m2 from 1, 5, and 10 dm2 was 95.3, 88.6, and 89.7% with the CV values 3.78, 4.41, and 4.97%, respectively. The absolute detection limit was 0.6 ng and the quantitation limit was 2 ng, but it was shown that these can be improved by immersion of the developed plate into a solution of liquid paraffin–n-hexane (1 + 2, v/v) to approximately 0.25 and 0.9 ng, respectively. The LOD of the method using detection without paraffin–n-hexane was 3, 0.6, and 0.3 μg/m2 by swabbing 1, 5, and 10 dm2, respectively. The method can be applied to routine control of pharmaceutical equipment cleanliness by sampling from stainless steel surface areas of 1 to 10 dm2 with acceptable residue limit/surface of 1 mg/m2.

Amoxicillin, substance-related to semisynthetic penicillin, has been widely used to treat infections caused by various microorganisms, however reports of suitable methods for the quantitative determination and indicative of the stability of formulations containing this substance are rare. Due to lack of studies on the forced degradation of the substance and on the need to monitor the quality of this type of formulation was proposed and validated a method for the determination of amoxicillin content in capsules by high-performance liquid chromatography - HPLC for the quality control of amoxicillin capsules, allowing the provision of useful information about the characteristics of this type of formulation and its stability. The method was validated for parameters of linearity, specificity, accuracy, precision, and robustness

Isocratic Mode

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.

Haedoksamul-tang (HST) is a traditional medical prescription comprising eight medicinal herbs: Angelica gigas, Cnidium officinale, Coptis japonica, Gardenia jasminoides, Paeonia lactiflora, Phellodendron amurense, Rehmannia glutinosa, and Scutellaria baicalensis. HST is used to treat blood circulation disorders and has anti-inflammatory, hemostatic, and anticonvulsant effects. In this study, a high-performance liquid chromatography/photodiode array detector (HPLC–PDA) method was developed and validated for the simultaneous determination of four marker compounds in HST, namely, berberine, palmatine, geniposide, and paeoniflorin. Four standard solutions and HST sample solutions were analyzed using a reverse-phase SunFire®C18 column (4.6 × 250 mm, 5 μm) using a 0.05% aqueous formic acid/methanol gradient. The column temperature, flow rate, injection volume, and wavelengths used were 28 ± 2 ℃, 1.0 mL/min, 10.0 μL, and 230 nm and 240 nm, respectively. Calibration curves of the four marker compounds showed good linearity (r2 ≥ 0.9994), and limits of detection (LODs) and quantification (LOQs) were in the ranges 0.131–0.296 μg/mL and 0.398–0.898 μg/mL, respectively. Ranges of intra- and inter-day precisions and accuracies values were 96.74–102.53% and 97.95–100.83%, respectively, and relative standard deviation (RSD) values were all <4%. Recoveries averaged 92.33–116.72% with RSD values <5%. Quantitative analysis for the four marker compounds showed geniposide (10.77 mg/g) was most abundant in HST.
