Dünnschichtchromatographischer Nachweis von vier therapeutisch wichtigen imidazolinderivaten

Chromatography

“…Common barbiturates have been analyzed by TLC on cellulose plates using a sodium sulfate-mercurous nitrate color reagent at a sensitivity of about 0.4 Mg (78). Other drugs which have been analyzed by thin-layer chromatography include imidazoline derivatives (134), appetite depressants, e.g. Preludin, Ritulin (325), anticonvulsant drugs (341), and acetanilide-based analgesics (135).…”

A fluorescence optosensor for analyzing naphazoline in pharmaceutical preparations

“…There are several analytical methods to determine NPZ; the majority are photometric [2,3] and chromatographic methods: thin layer chromatography [4], gas chromatography [5] and high performance liquid chromatography [6,7]. Capillary electrophoresis [8][9][10] and atomic absorption and emission [11] methods have also been published.…”

Flow-injection chemiluminescence determination of phentolamine based on its enhancing effect on the luminol–potassium ferricyanide system

“…The monitoring of such drug is important for quality assurance in preparations and for obtaining optimum therapeutic concentrations. For its measurement, several methods have been reported, such as spectrophotometry [8], thin-layer chromatography [9,10], spectrofluorimetry [11], gas chromatography (GC) with electron capture detection [12], high-performance liquid chromatography (HPLC) with UV [10,13,14], electrochemical [15,16] or mass spectrometric detection [10,17]. However, most of them have one or more drawbacks.…”
