Gas-liquid chromatographic determination
A method for the determination of total bile acids in human feces that is suitable for routine application is described and discussed. Bile acids are extracted from freezedried feces with acetic acid and toluene, in the presence of the i?ternal standard 23-nordeoxycholic acid. After saponification of the extract, bile acids and the internal standard are methylated and converted by mild chromic ...

متن کاملGas-liquid chromatographic determination of nicotine and cotinine in plasma.
We report a procedure for determining nicotine and cotinine in plasma. Nicotine is extracted from 1 ml of plasma with diethyl ether, back extracted, and analyzed by gas-liquid chromatography with a nitrogen/phosphorus detector. Nicotine and its internal standard, modaline, had retention times of 1.9 and 2.9 min, respectively. Cotinine is then extracted from the same plasma with dichloromethane ...
متن کاملGas-liquid chromatographic determination of vitamin D in multivitamin preparation.
Gas-liquid chromatographic (GLC) determination of vitamin D in multivitamin preparations was investigated and a simple routine method was established. The unsaponifiable matters of a sample was applied to a thin-layer chromatography (TLC) plate using Kieselgel GF254 as an adsorbent and a mixture of n-hexane-ethyl acetate (4:1) as a developing solvent. The scraped zones corresponding to vitamin ...
