Separation of lipid classes by chromatography on florisil

Large-scale separation of fatty acid methyl esters by column chromatography on acid-washed Florisil impregnated with silver nitrate.

Rapid separation and quantification of lipid classes by high performance liquid chromatography and mass (light-scattering) detection.

The major lipid classes in animal tissues, varying in polarity from cholesteryl esters to lysophosphatidylcholine, can be separated and accurately quantified by high performance liquid chromatography on a short 3-mu silica column and using a mass (light-scattering) detector. Sample sizes of 0.2 to 0.4 mg are optimum and the analysis is completed in only 20 min. The column is reactivated and rea...

Separation of hydroxyanthraquinones by chromatography

Было изучено хроматографическое поведение гидроксиантрахинонов. Хорошее разделение было достигнуто при использовании предложенных новых хроматографических систем: бумажная хроматография смесью уксусной кислоты и воды на простой бумаге или бумаге импрегнированной оливковым мас­ лом, тонкослойная хроматография на целлюлозе импрегнированной диметилформамидом и на силикагеле без или с импрегнацией ...

Ribonucleotides of RNA: separation by chromatography on sheets of diethylaminoethylcellulose.

The four main ribonucleotides of RNA can be separated on diethylaminoethylcellulose paper sheets, with results comparable to column chromatography, by irrigation with 0.05M formic acid for 2 to 3 hours, and then reversing the direction of irrigation with 4M formic acid.

Separation of Folk Acid Compounds by Gel Chromatography on Sephadex

The separation of folate compounds has been achieved by gel chromatography and the effect of buffer concentration on the elution pattern of folate derivatives was investigated by Sephadex G-15 and G-25 column chromatography. Highly conjugated polyglutamates appear in the effluent considerably sooner when eluted with water than would be expected from their molecular weights. Monoglutamates, exce...
