Quantitative determination of hippuric and m-methylhippuric acids in urine by high-speed liquid chromatography.
High-speed liquid chromatography employing an ultraviolet photometric detector has been applied to the simultaneous determination of hippuric and m-methylhippuric acids in urine. Reversed-phase partition chromatography is carried out on a muBondapak C18 column with methanol-water as the eluent system. This method obviates the necessity for isolation or reaction of these acids before assay. The ...
متن کاملThin-layer chromatography of hippuric and m-methylhippuric acid in urine after mixed exposure to toluene and xylene.
The separation of hippuric and m-methylhippuric acid as toluene and m-xylene metabolites present in urine of people exposed simultaneously to toluene and xylene is described. Chloroform was used for hippuric and m-methylhippuric acid extraction. Satisfactory separation of these metabolites was obtained on TLC plates covered with silica gels and developed in chloroform acetic acid-water (4:1:1);...

15 صفحه اولA high-performance thin-layer chromatographic method for chlorogenic acid and hyperoside determination from berry extracts
The present study investigates a quantitative high performance thin layer chromatographic (HPTLC) method for chlorogenic acid and hyperoside determination from berry extracts. Chlorogenic acid and hyperoside were extracted using a methanol and water mixture and separated on a HPTLC 60F254 silica gel plates with ethyl acetate, acetic acid, formic acid and water 10:1.1:1.1:2.3 (v/v/v/v) as mobile...

Buchet, J. P., and Lauwerys, R. R. (1973). British Journal ofIndustrial Medicine, 30, 125-128. Measurement of urinary hippuric and m-methylhippuric acids by gas chromatography. A gas chromatographic method for the determination of hippuric and m-methylhippuric acids in urine is described. A known amount of heptadecanoic acid (internal standard) is added to the urine before its extraction with e...
