SPE/TLC/Densitometric Quantification of Selected Synthetic Food Dyes in Liquid Foodstuffs and Pharmaceutical Preparations
Selected synthetic food dyes (tartrazine, Ponceau 4R, Brilliant Blue, orange yellow, and azorubine) were isolated from liquid preparations (mouthwashes and beverages) by Solid Phase Extraction on aminopropyl-bonded silica with diluted aqueous sodium hydroxide as an eluent. The extraction step was followed by thin layer chromatography on silica gel 60 with chloroform-isopropanol-25% aq. ammonia ...
متن کاملA validated stability-indicating TLC-densitometric method for the determination of stanozolol in pharmaceutical formulations
BACKGROUND Stanozolol is a synthetic derivative of dihydrotestosterone (DHT), and one of the frequently detected anabolic steroids in doping analysis. The current work describes the development and validation of the stability-indicating TLC-densitometric method for sensitive and specific estimation of stanozolol even its degradation product being there. Precoated silica gel TLC aluminium plates...
متن کاملTLC--densitometric method for qualitative analysis of betamethasone and its related compounds in pharmacautical preparations.
A new simple and rapid TLC-densitometric procedure for the separation and identification of betamethasone and its related substances, betamethasone-17,21-dipropionate, betamethasone-17-valerate, betamethasone-21-valerate and also betamethasone disodium phosphate was developed. One of the chromatographic systems proposed in this study, which has been satisfactory applied in separation of four pa...
متن کاملSpectrophotometric Determination of Diclofenac in Pharmaceutical Preparations
Neste trabalho é proposto um método espectrofotométrico modificado para a determinação de diclofenaco em preparações farmacêuticas. Usa-se solução de cobre(II) como reagente, o que leva à formação de um complexo cobre(II)-diclofenaco de cor verde, com máximo de absorção em 680 nm. Foram estudadas as influências: do pH; da concentração de cobre(II); do uso de ácido acético na solução de cobre(II...
متن کاملSpectrophotometric Determination of Metronidazole in Pharmaceutical Preparations
A rapid and sensitive spectrophotometric method is proposed for determination of Metronidazole. The method depends on the reduction of Metronidazole molecule with zinc dust and hydrochloric acid flowed by diazotation and coupling with 8-quinolinol to give colored chromogens easily measured spectrophotometrically which has λmax= 437 nm. The experimental conditions were optimized and berr’s law w...
