Thin Layer Chromatographic Separation of Benzodiazepine Derivates

abstract: In this paper we describe the thin layer chromatographic separation of eight of the most frequently used benzodiazepine derivates (alprazolam, bromazepam, chlorazepate potassium, chlordiazepoxide, diazepam, nitrazepam, oxazepam) and their degradation products after acid hydrolysis. Our aim was not only to develop a simple, rapid and efficient method for their separation but also the o...

Modeling of thin-layer chromatographic separation of androstane isomers

Modeling of thin-layer chromatographic separation of androstane isomers to find the optimum mobile phase is described in this paper. The isomers of androstane are present in a variety of samples, so achieving their optimum thin-layer chromatographic separation is very important. A mathematical model was developed and tested. The model takes into account the interaction between solvents and uses...

Polyamide thin-layer chromatographic separation of DOPA metabolites and related compounds.

The use of L-DOPA* in therapy of Parkinsonisml has stimulated interest in the metabolism of this compound in normal’ and pathologic3 states. Goodall and Alton’ separated 35 DOPA metabolites from the urine of healthy subjects by GLC. Seventeen of these metabolites, including 11 acidic compounds, were unidentified. Recently, 3-hydroxyphenylacetic acid, 3-methoxy-4-hydroxyphenyllactic acid, and 4-...

A thin-layer-chromatographic procedure for the separation of pethidine and its metabolites in urine [proceedings].

Pethidine, first used in 1940, has retained its position as the most widely used obstetrical analgesic (Burt, 1971 ; Jaffe & Martin, 1975; ODonoghue, 1971 ; O'Driscoll etal., 1973; Rosen, 1971). The metabolismof pethidine in the pregnant woman gives rise to norpethidine, pethidinic acid and norpethidinic acid, and conjugated pethidinic acid and norpethidinic acid respectively. A simple t.1.c. p...

Improved thin-layer chromatographic method for the separation of cholesterol, egg phosphatidylcholine, and their degradation products.

Degradation products of egg phosphatidylcholine (EPC) and cholesterol were analyzed with different normal- and reversed-phase thin-layer chromatography (TLC) systems. The best separation, in terms of the highest number of degradation products from both analytes, was obtained with a reversed-phase system, using butanol-methanol-water-96-98% (v/v) acetic acid (40 + 40 + 20 + 4, v/v/v/v) as the mo...
