A novel High-Performance Thin-Layer Chromatography (HPTLC) method was portrayed for the determination of Fenticonazole Nitrate (FTZ) in Bulk and Vaginal Capsules. The estimation of Fenticonazole Nitrate was achieved on aluminium pre-coated sheets of silica gel 60 F(10 cm × 10 cm) using mobile phase Toluene: Methanol: Triethylamine (4:1:0.5 v/v/v). Densitometry detection of Fenticonazole Nitrate was performed at 254nm. Fenticonazole nitrate demonstrated a strong correlation with a coefficient of correlation of 0.999 over the concentration range of 500 – 3000 ng/band. The Rvalue for Fenticonazole Nitrate was found to be 0.65. As per International Conference on Harmonization the established method was successfully validated to various parameters like accuracy, precision, sensitivity, specificity, robustness and shows the satisfactory results for all parameters. The recognized method is simple, accurate, precise, robust, sensitive and economical in nature. This method can be used for quality control analysis of Fenticonazole Nitrate in bulk and vaginal capsules.

Abstract In this paper, a high-performance thin-layer chromatography (HPTLC) method combined with densitometry has been described. Chromatography was performed on silica gel Si 60F254 plates using dichloromethaneethyl acetateformic acid (9.5 + 0.5 + 0.1, v/v) mobile phase. This method has been successfully applied for the determination of phenobarbital in pharmaceuticals. Obtained results were comparable with traditionally used column high-performance liquid chromatography (HPLC) methods. For the proposed procedure, linearity (r > 0.999), sensitivity (limit of detection 0.4 g/spot), recovery (97.8102.1%), and repeatability were found to be satisfactory. The HPTLC-densitometry method has many advantages, such as simplicity, reasonable sensitivity, rapidity, and low cost, and it can be successfully used in routine quality control of multidrug preparations containing barbiturates.

Background: Boswellic acids (BAs) are extracted from oleo gum of Boswellia serrata and are utilized as potential anti-inflammatory, hypolipidemic, immunomodulatory and antitumor specialists. The present examination was meant to assess KBA and AKBA in Boswellia serrata separate by High-Performance Thin Layer Chromatography (HPTLC). Methods: The separation of bioactive compounds was performed utilizing mobile phase glacial acetic acid, n-hexane, ethyl acetate and toluene (0.3: 1: 8: 2) (v/v/v/v) and distinguished at wavelength 254 nm. The technique was approved for linearity, precision, accuracy, limit of detection (LOD), limit of quantification (LOQ), and so forth by International Conference on Harmonization guidelines. Results: The calibration range was observed to be 2- 14 μg/band for both the bioactive compounds. KBA was isolated with an Rf estimation of 0.39 ± 0.02 and AKBA with an Rf estimation of 0.42 ± 0.02. The accuracy was seen to be as high as 99.17% and 97.42 for KBA and KBA, respectively. The percentage RSD value for intra-day and between day varieties was under 2%. The system indicated high affectability and specificity. Conclusion: The developed HPTLC method was simple, precise, robust, specific, rapid, and costeffective and could be used for quality control analysis and quantification of KBA and AKBA in different herbal formulations containing the plant species.

Background: Jingzhiguanxin (JZGX) tablet, a traditional Chinese prescription, is commonly used for treating coronary heart disease and angina pectoris in the clinic. There are six active components (Danshensu (DSS), Protocatechuic aldehyde (PD), Paeoniflorin (PF), Ferulic acid (FA), Salvianolic acid B (Sal B) and Tanshinone IIA (TA)) in JZGX tablet. </P><P> Objective: In this paper, a simple and reliable method was used for simultaneous determining the six active components by high-performance liquid chromatography coupled with diode array detector (HPLC-DAD). Methods: These six active components were separated on an Agilent Zorbax Eclipse XDB-C18 column (150 mmx4.6 mm, 5 µm) at 30 °C. Acetonitrile (A), methanol (B) and 0.5% H3PO4 aqueous solution (C) were used as mobile phase for gradient elution. The flow rate was 1 mL/min and the detection wavelengths were set at 280 nm for DSS, PD and Sal B, 230 nm for PF, 320 nm for FA and 270 nm for TA, respectively. Results: All of the six components showed good linearity regressions (r2≥0.9997) in the detected concentration range. The recovery rates and coefficient of variation (CV) for all analytes were 98.66%- 100.18% and 0.75%-1.89%, respectively. This method was successfully applied to simultaneously determine the six components in JZGX tablet from different batches and manufacturers. Conclusion: The validated method can be used in routine quality control analysis of JZGX tablet without any interference.

A simple, rapid and accurate and stability indicating RP-HPLC method was developed for the determination of valsartan in pure and tablet forms. The method showed a linear response for concentrations in the range of 50-175 µg/mL using 0.01 M NH4H2PO4(pH 3.5) buffer: methanol [50:50] as the mobile phase with detection at 210 nm and a flow rate of 1 mL/min and retention time 11.041 min. The method was statistically validated for accuracy, precision, linearity, ruggedness, robustness, forced degradation, solution stability and selectivity. Quantitative and recovery studies of the dosage form were also carried out and analyzed; the % RSD from recovery studies was found to be less than 1. Due to simplicity, rapidity and accuracy of the method, we believe that the method will be useful for routine quality control analysis.

Abstract Tephrosia purpurea (L.) Pers., commonly known as “sarpunkha” and “wild indigo”, is being used in traditional systems of medicine to treat liver disorders, spleen and kidney. In the present study, a validated High Performance Thin Layer Chromatography (HPTLC) method was established for the estimation of lupeol, β-sitosterol and rotenone in various extracts of T. purpurea with the aim to see the effect of seasons on the quantity of aforesaid phytoconstituents. The plant material was collected in summer (April), rainy (August) and winter (December) during 2013–2014 from Lucknow, India. The method was validated in terms of precision, repeatability, specificity, sensitivity linearity and robustness. The method permits reliable quantification and showed good resolution on silica gel with toluene-ethyl acetate-formic acid (9:1:1 v/v/v) as mobile phase, and characteristic bands of β-sitosterol, rotenone and lupeol were observed at Rf 0.38, 0.45 and 0.52, respectively. The content of aforesaid phytoconstituents varies from season to season and extract to extract. Our finding indicated that winter season (December) may not be appropriate for collection of T. purpurea for the preparation of therapeutic formulations because of the high content of rotenone, a known insecticide that is responsible for Parkinson’s disease and associated with heart failure, fatty liver and liver necrosis.

A rapid and simple high performance liquid chromatography method was developed and validated at λ=275 nm for simultaneous determination of methocarbamol, paracetamol and diclofenac sodium (lamotrigine as an internal standard) from pharmaceutical preparation. The separation was performed using methanol: water: GAA, in the ratio of 400:600:05 (v/v) as the mobile phase. The detector response was linear in the range of 5 to 45 μg, 3.25 to 29.25 μg, 0.5 to 4.5 μg for methocarbamol, paracetamol and diclofenac sodium respectively. The percentage assay of methocarbamol, paracetamol and diclofenac sodium was found between 100, 99.76 and 99.31% respectively. The described method has the advantage of being rapid and easy hence it can be applied for routine quality control analysis.
