Thin-layer Chromatographic Separation of Penicillins on Stannic Arsenate–cellulose Layers
نویسندگان
چکیده
Thin-layer chromatographic separation of penicillins has been performed on stannic arsenate–cellulose layers. RF values of penicillins were determined after use of different mobile phases. Amoxycillin and ampicillin were selectively separated from binary and ternary synthetic mixtures. Amoxycillin and ampicillin in commercially available drugs were also separated and were quantitatively determined.

Selective Tlc Separation of Lysine and Threonine in Pharmaceutical Preparation
Thin-layer chromatography of α-amino acids has been performed on layers prepared from a 1:4 stannic arsenate–cellulose mixture. RF values of the amino acids were determined after development with a variety of mobile phases. Important synthetic ternary separations have been achieved on the basis of different RF values. Lysine and threonine have been selectively separated and quantitatively deter...
متن کاملSome simple thin-layer chromatographic systems for the separation of purines and purine nucleosides.
Studies on nucleic acid metabolism often require the analytical separation of nucleic acid derivatives and are facilitated by chromatographic methods which are rapid and convenient. Column chromatography on ion exchange resins (1)) paper chromatography (2)) and paper electrophoresis (3) are among the methods used routinely for such separations. Even though these techniques have been employed wi...

PURPOSE The paper describes some thin layer chromatographic procedures that allow simple and rapid separation and identification of penicillins and cephalosporins from complex mixtures. METHODS Using silicagel GF254 as stationary phase and selecting different mobile phases we succeeded in the separation of the studied beta-lactamins. Our aim was not only to develop a simple, rapid and efficie...
متن کاملStationary phases for thin-layer chromatography.
This paper presents a review of the literature concerning development of the stationary phases for thin-layer chromatography (TLC) in the last ten years. The silica gel remains the most important adsorbent for TLC separation. The kinetic properties of the silica-gel thin layer and the new TLC plates have been presented. Other materials used as stationary phase were alumina, zirconium oxide, Flo...
