High Pressure Liquid Chromatography of Anthocyanins

Canadian Institute of Food Science and Technology Journal, 1975
Abstract An investigation of several high pressure liquid chromatographic (hplc) systems, potentially useful in rapidly separating mixtures of anthocyanins, indicated that a polyamide material called Pellidon performed the best. Three monoglucosides of malvidin, petunidin and peonidin were successfully separated in less than 20 minutes on a ⅛″ × 4 ...

High-pressure liquid chromatography of carbohydrates

Journal of Chromatography A, 1974
Abstract A procedure is described for the separation of water-soluble wood polysaccharides on Bio-Glas (granular porous glass) and Bio-Gel P (polyacrylamide) packed columns using high-pressure liquid chromatography (HPLC). An example of HPLC employing non-aqueous solvent systems and EM Gel OR-PVA (vinyl acetate copolymer) type packing materials is ...

Laboratory Automation of High‐Pressure Liquid Chromatography

Journal of Pharmaceutical Sciences, 1975
An automated system for high-pressure liquid chromatography was developed. The system is built around commercial modules wherever possible, modified to varying degrees. An automatic sampler, a sample pump, a high-pressure sampling valve, a recorder with an integrator, and a high-pressure liquid chromatograph comprise the commercial instruments. Relays,

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

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

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,
