Alkaline solvent systems for thin-layer chromatography of bile acids.
Thin-layer chromatographic separation of the common bile acids and their taurine and glycine conjugates in chloroform-methanol-ammonia is reported. An alkaline system offers advantages for the separation and nondestructive staining of bile acid conjugates.
متن کاملNew solvent systems for thin-layer chromatography of bile acids.
A modified thin-layer chromatographic technique separates small amounts of glycochenodeoxycholic from glycodeoxycholic acid and the major taurine conjugates and unconjugated bile acids from one another.
متن کاملImproved thin-layer chromatography of disaturated phosphatidylcholine in amniotic fluid.
We describe an indirect test of fetal lung maturity: the quantitation of disaturated phosphatidylcholine in amniotic fluid. The lipids in samples of amniotic fluid from 172 patients were reacted with osmium tetroxide, and disaturated phosphatidylcholine was then isolated by thin-layer chromatography. Interfering substances were retained by a pre-adsorbent layer. The charred disaturated phosphat...

متن کاملThin-Layer (Planar) Chromatography
Synthetic dyes comprise a large group of organic, organic salt and organometallic compounds which number in the thousands. Most individual dyes are assigned colour index (CI) numbers which helps to identify structure and properties as well as identity where a series of names have been used by the manufacturers for the same dye. Pigments are also listed and can be either organic or inorganic in ...
