Chromatographic analysis of anticancer drugs
Journal of Chromatography B: Biomedical Sciences and Applications, 1990The present review on the methods for the analysis of anticancer drugs should be seen as an addition to the excellent work of Eksborg and Ehrsson published half a decade ago in this journal (Vol. 340, p.31). The style and format have been followed closely, with the focus again on chromatographic techniques.

Chromatographic analysis of plasmalogens
Chromatographic Reviews, 1968Abstract Chromatography has been widely used in the studies on plasmalogens. It has been used for the following purposes: 1. A rapid and simultaneous determination in total lipid extracts of phosphatide classes and their constituent plasmalogens by reaction two-dimensional thin-layer chromatography. 2.

Polyhydroxy alkaloids: chromatographic analysis
Journal of Chromatography A, 2002Polyhydroxy alkaloids are a burgeoning category of natural products that encompass several structural types and generally exhibit potent activity as inhibitors of glycosidases. As presently defined the group consists of monocyclic or bicyclic aLkaloids of the pyrrolidine, piperidine, pyrrolizidine, indolizidine and tropane classes, bearing two or more ...

Chromatographic analysis of photosensitizing dyes
Journal of Chromatography A, 1966Abstract Simple one-phase solvent systems were developed which are useful for the chromatography of a variety of water-soluble acid and alkaline dyes. Using these solvents the purity of several commercial preparations of thiazine, azine, acridine, and xanthene dyes was assayed, and it was shown that such preparations can contain up to sixty percent ...

Gas chromatographic analysis of monoalkylhydrazines
Journal of Chromatography B: Biomedical Sciences and Applications, 1987A quantitative electron-capture gas chromatographic assay procedure was developed for the analysis of monoalkylhydrazines in biological samples. Application to the analysis of phenelzine was demonstrated. Four monoalkylhydrazines were analyzed in whole blood by reaction with pentafluorobenzaldehyde to form stable hydrazone derivatives which were ...

The chromatographic analysis of reserpine preparations
Journal of the American Pharmaceutical Association (Scientific ed.), 1955Abstract Methods are presented for the analysis of reserpine preparations by chromatography on paper and on liquid‐liquid partition columns. The former is used for the qualitative examination of samples and the latter for the quantitative assay of reserpine contents.

Ion Chromatographic Analysis of Hydroxyapatite
Analytical Letters, 2009An ion chromatographic method was developed for the determination of cations and anions in hydroxyapatites. It involved high pressure microwave-assisted acid digestion in closed TFM vessels in order to achieve complete dissolution of samples in less than half an hour.

Tandem technologies in chromatographic analysis
Chinese Journal of Chromatography, 2018The acquisition of chemical compounds information from samples depends on the separation as well as detection techniques. Usually, it is difficult to achieve the separation and identification of all components in complex samples by a simple one-dimensional chromatographic method.

Chromatographic analysis of alkylresorcinols and their metabolites
Journal of Chromatography A, 2004Alkylresorcinols (AR) are phenolic lipids present in high amounts in the bran fraction of wheat and rye. AR are of scientific interest as bioactive compounds, as markers for the presence of wholegrain or bran fractions of wheat and rye in food products, and as possible biomarkers of intake for wholegrain wheat and rye.
