Determination of active ingredient in synthetic pyrethroid formulations by high-performance thin-layer chromatography/densitometry.
A new, simple, precise, and rapid high-performance thin-layer chromatography (HPTLC) method was developed for the analysis of commercial emulsifiable concentrate (EC) formulations of cypermethrin, alpha-cypermethrin, and lambda-cyhalothrin. A known amount of reference grade synthetic pyrethroid and its EC formulation was subjected to TLC, and the amount of pesticide present in the active ingred...
متن کاملDetermination of polyphenolics in extracts of Potentilla species by high-performance thin-layer chromatography photodensitometry method.
INTRODUCTION Separation of polyphenolics in different plant materials using high-performance thin-layer chromatography (HPTLC) represents an effective method for their detection and quantification. OBJECTIVE To develop a simple, specific, precise, sensitive and accurate method for the simultaneous quantification of tiliroside (TRS), methyl brevifolincarboxylate (MBR) and ellagic acid (EA) in ...
متن کاملDetermination of gatifloxacin and ornidazole in tablet dosage forms by high-performance thin-layer chromatography.
A simple and sensitive high-performance thin-layer chromatography (HPTLC) method has been developed for the quantitative estimation of gatifloxacin and ornidazole in its combined dosage forms. Gatifloxacin and ornidazole were chromatographed on silica Gel 60 F(254) TLC plate using n-butanol:methanol:ammonia (6 M) (8:1:1.5 v/v) as the mobile phase and scanned at 302 nm using a Camag TLC Scanner ...
متن کاملDetermination of oxycodone hydrochloride in oral solutions by high-performance thin-layer chromatography/densitometry.
A thin-layer chromatography/densitometry method was developed and validated for the determination of oxycodone hydrochloride in oral solutions by using silica gel plates. A horizontal technique was used for development of the plates. The optimum composition for the mobile phase, which provided a suitable Rf value of 0.6 for oxycodone, was propanol-acetic acid-water-25% ammonia-methanol (20 + 1 ...
متن کاملDetermination of Ochratoxin A in Wine by High-Performance Thin-Layer Chromatography using Charged Coupled Device
Um método foi desenvolvido e validado para a determinação de ocratoxina A (OTA) em vinho. Foi utilizado um sistema contendo um detector de carga acoplada (CCD) para adquirir as imagens fluorescentes da micotoxina obtidas a partir das placas de cromatografia em camada delgada de alta eficiência (HPTLC) sob luz ultravioleta. O método desenvolvido mostrou recuperação média de 90,4%. O limite de qu...
