Capillary gas-liquid chromatography of glycine-conjugated bile acids without prior hydrolysis.
Journal of Lipid Research, 1986 A method is described for the gas-liquid chromatographic (GLC) analysis of intact glycine conjugates of the major bile acids present in human plasma. It is, therefore, now possible to analyze glycine-conjugated and unconjugated bile acids together on a ...

Alkanes from plants of the genus achillea [PDF]
Journal of the Serbian Chemical Society, 1999 The hydrocarbon fractions of three species of Achillea L. have been analysed by capillary gas chromatography (GC) and GC-mass spectrometry(GC-MS) and were shown to consist of the conventional, odd-carbon number dominant distributions of n-alkane
