Thimerosal Determination by High-Pressure Liquid Chromatography

Journal of Pharmaceutical Sciences, 1978
A sensitive and useful high-pressure liquid chromatographic method for the determination of intact thimerosal was developed. This method is extremely fast and reliable, and its inherent specificity makes it a breakthrough over other common wet chemical methods.

Analysis of leukotrienes by high-pressure liquid chromatography

Analytical Biochemistry, 1981
Abstract A reversed-phase high-pressure liquid chromatographic procedure has been developed to separate and quantitate leukotrienes. This procedure is based on the ultraviolet absorption of the conjugated triene moiety of these compounds and is sensitive to the nanogram level.

High pressure liquid chromatography of neutral glycosphingolipids

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1972
Abstract A system for the separation of neutral glycosphingolipids by high pressure liquid chromatography of their benzoylated derivatives has been devised. Serum mono-, di-, tri-and tetraglycosylceramides are completely resolved within 25 min. A full scale recorder response can be obtained with approximately 1.0 nmole of glycolipid.

Analysis of Trisulfapyrimidines by High-Pressure Liquid Chromatography

Journal of Pharmaceutical Sciences, 1973
Abstract: The application of high-pressure liquid chromatography to the separation and analysis of trisulfapyrimidines in pharmaceutical dosage forms is demonstrated. The preparation of samples of both tablet and suspension dosage forms is simple and rapid.

Anthracycline Assay by High-pressure Liquid Chromatography

Journal of Pharmaceutical Sciences, 1981
A general method of analysis of anthracycline concentrations was developed. Drug is extracted from plasma with organic solvent and separated from metabolites by high-pressure liquid chromatography on an aminocyanosilica column. Detection and quantitation are by the endogenous fluorescence of compounds having an intact tetracyclic ring structure. Limits

Assay of Cefotaxime by High-Pressure-Liquid Chromatography

Chemotherapy, 2009
A high-pressure-liquid chromatographic (HPLC) procedure for quantitative assay of cefotaxime (CT) and its major metabolite in serum of normal individuals, desacetyl cefotaxime (DACT), is described. It employs Lichrosorb RP-8, elution with phosphoric-acid-methanol and UV absorption at 310 nm.

Mexiletine in Plasma by High Pressure Liquid Chromatography

Therapeutic Drug Monitoring, 1981
We report here a novel high pressure liquid chromatographic (HPLC) technique for use in therapeutic monitoring of the primary amine antiarrhythmic drug mexiletine in plasma samples. Mexiletine and its structural analogue, the internal standard Ko 768, are extracted with heptane after alkalinization of the sample. The extracts are evaporated to dryness,

High-pressure liquid chromatography of steroidal alkaloids

Journal of Chromatography A, 1976
High-pressure liquid chromatography was used to separate the following steroidal alkaloids: tomatidine, solanidine, solasodine, rubijervine, veratramine and jervine. The method was used to prepare crystalline solanidine from a crude mixture of aglycones obtained from Solanum chacoense, and to separate radioactive solanidine from extracts of potato ...

Determination of hydroxyproline by high pressure liquid chromatography

Analytical Biochemistry, 1992
A rapid, precise, and simple HPLC method provides an assay of hydroxyproline from tissue extracts or solutions of collagen. Samples are hydrolyzed with 6 N HCl, derivatized with phenyl isothiocyanate, and chromatographed on a small, C18 reverse-phase HPLC column. Hydroxyproline (Hyp) is separated from other amino acids and detected by absorption at 254

Determination of Thiopental by High Pressure Liquid Chromatography

Acta Pharmacologica et Toxicologica, 1979
AbstractA specific and rapid reverse phase HPLC‐method for the determination of thiopental in serum and in protein free solutions is described. No extraction is used. The detection limit is about 0.090 μg/ml for serum and about 0.030 μg/ml for buffer solutions. The retention time is 3.80 min.
