Determination of glucosamine and carisoprodol in pharmaceutical formulations by LC with pre-column derivatization and UV detection.
A simple and reliable precolumn derivatization liquid chromatography method with ultraviolet detection has been developed and validated for the analysis of glucosamine (GS) in various dietary supplement formulations and raw materials. Additionally, the proposed method was used for analysis of carisoprodol (CR) found in ternary mixture with paracetamol (PR) and caffeine (CF). The linearity range...
متن کاملdevelopment and validation of a new method for determination of topiramate in bulk and pharmaceutical formulation using high performance liquid chromatography-uv detection after pre-column derivatization
in published high performance liquid chromatographic (hplc) methods for analysis of topiramate (tpm) in pharmaceutical dosage forms and raw materials refractive index detector (rid) has been used which is not available in many laboratories and has low sensitivity. we described a new, sensitive and simple hplc method for determination of topiramate in pharmaceutical forms and in-virto dissolutio...
متن کاملDetermination of urinary norepinephrine and epinephrine by liquid chromatography with fluorescence detection and pre-column derivatization.
We assayed norepinephrine and epinephrine by utilizing solvent extraction, fluorescence derivatization, and "high-performance" liquid chromatography. A 100-microL aliquot of urine was extracted twice according to Smedes et al. (J Chromatogr 1982;231:25-39) and subsequently incubated with 1,2-diphenylethylenediamine. A 100-microL aliquot of the resulting mixture was injected into a reversed-phas...
متن کاملDetermination of sodium hyaluronate in pharmaceutical formulations by HPLC–UV
A liquid chromatography (HPLC) method with UV detection was developed for determination of sodium hyaluronate in pharmaceutical formulation. Sodium hyaluronate is a polymer of disaccharides, composed of d-glucuronic acid and d-N-acetylglucosamine, linked via alternating β-1, 4 and β-1, 3 glycosidic bonds. Being a polymer compound it lacks a UV absorbing chromophore. In the absence of a UV absor...
متن کاملDetermination and validation of duloxetine hydrochloride in capsules by HPLC with pre-column derivatization and fluorescence detection.
A high-performance liquid chromatographic (HPLC) method is described for the determination of duloxetine hydrochloride in capsules. The method was based on pre-column derivatization with 4-chloro-7-nitrobenzo-2-oxa-1,3-diazole using the fluorimetric detection technique. Duloxetine hydrochloride was analyzed by HPLC using an Inertsil C18 column (5 μm, 150 × 4.6 mm) and mobile phase consisted of ...
