Resolution of promethazine, ethopropazine, trimeprazine and trimipramine enantiomers on selected chiral stationary phases using high-performance liquid chromatography
Autor: Garratt W. Ponder, James T. Stewart, Chandra Sekar Ramanathan, Amanda G. Adams, Sandra L. Butram
Publikováno v: Journal of Chromatography A. 692:173-182
The separation of the enantiomers of three phenothiazines and a dibenzazepine were investigated on several different chiral stationary phases without the use of derivatization or column switching. The phenothiazines selected were promethazine, ethopr

High-performance thin-layer chromatographic determination of digoxin and related compounds, digoxigenin bisdigitoxoside and gitoxin, in digoxin drug substance and tablets
Autor: James T. Stewart, Garratt W. Ponder
Publikováno v: Journal of Chromatography A. 659:177-183
A high-performance thin-layer chromatographic (HPTLC) method for the determination of digoxin and its related compounds digoxigenin bisdigitoxoside (DBD) and gitoxin in digoxin drug substance and tablets was developed. Separation of the three compoun

A liquid chromatographic method for the determination of promethazine enantiomers in human urine and serum using solid-phase extraction and fluorescence detection
Autor: James T. Stewart, Garratt W. Ponder
Publikováno v: Journal of pharmaceutical and biomedical analysis. 13(9)
A LC method was developed for the concurrent assay of R(+) and S(-) promethazine from human urine and serum. The method involves the use of solid-phase extraction for sample clean-up. Chromatographic resolution of the enantiomers was performed under
