Analytical methods for food antioxidants including ascorbic acid, erythorbic acid, ascorbyl palmitate (AP), and ascorbyl stearate (AS), were validated using high performance liquid chromatography. Validation parameters such as linearity, limit of detection (LOD), limit of quantification (LOQ), and recovery were tested using lard and cider as food model systems. Linearity of ascorbic acid and erythorbic acid were both higher than (R2> 0.99), LOD of these compounds were 0.46 and 0.48 μg/mL, respectively and LOQ were 1.39 and 1.45 μg/mL, respectively. The recovery rates of these compounds were

A simple, sensitive and accurate RP-UPLC method has been developed for the determination of Linezolid in Tablet formulation. The mix of the Linezolid was found to be 251nm in Acetonitrile: Buffer [40:60(v/v)]. The method shows high sensitivity with linearity 5 to 30μg/ml (regression r2 = 0.999). This method was tested and validated for various parameters according to ICH guidelines and USP. The Detection limit and quantitation limit were found to be 50mg ml–1 and 150 mg ml–1 in Acetonitrile: Buffer [40:60(v/v)] respectively.

The main objective of method validation of Lurasidone HCl as a tablet dosage form is to validate the method as in-house method. As this tablet dosage form is not registered in any of Pharmacopeia, so the method is developed and validated for further studies.

Abstract An interlaboratory study of the liquid chromatographic (LC) determination of tetracyclines—oxytetracycline (OTC), tetracycline (TTC), and chlortetracycline (CTC)—in animal tissues was conducted. Isolation was performed with oxalic buffer followed by dechelation and deproteination with oxalic acid–acetonitrile. The extract was cleaned with a styrene–divinylbenzene cartridge. LC analysis was performed with a PLRP-S column and 0.01 M oxalic acid–acetonitrile (75 + 25, v/v) as mobile phase. Participants analyzed 2 control and 10 fortified porcine muscle and kidney samples.

Endosulfan lactone is a metabolite obtained from the biological oxidation of the insecticide endosulfan by action of the microorganisms present in the soil. This metabolite is more toxic and persistent than the parent compound. Therefore, it is extremely important to be able to determine the presence of this metabolite in the soil. However, accessible methods for extraction of endosulfan lactone in soil were not found in published literature. For this reason, the aim of this study was to evaluate two conventional methods of liquid–solid extraction for the determination of endosulfan lactone in

A simple and focused HPLC method is described for phentermine measurement. With a C18 column and a mobile phase made up of 40 volumes of methanol, 40 volumes of acetonitrile, and 20 volumes of water, the chromatographic separation was completed at a wavelength of 263 nm. For Phentermine, the method demonstrated linearity in the 50–150 µg/ml range (r2 = 0.990), and the drug amounts found using this suggested method nearly matched the label claim. It is clear from the previously described testing results and parameters that this newly developed approach for phentermine estimate is simple, accura
