      TLC of selected bile acids Detection and separation. J. Liq. Chromatogr. Relat. Technol. 31, 1373-1385 (2008). TLC of cholic acid, glycocholic acid, glycolithocholic acid, deoxycholic acid, chenodeoxycholic acid, glycodeoxycholic acid, and lithocholic acid on silica gel with concentration zone, prewashed with methanol and dried for 24 h at room temperature, in a saturated chamber. Best separation of the bile acids was achieved with n-hexane - ethyl acetate - methanol - acetic acid 202052. Detection by dipping for 15 s in sulfuric acid - methanol 119, followed by heating at 90 °C for 20 min provided better results than derivatization by spraying with 10 % phosphomolybdic acid in ethanol. Quantitative determination by absorbance measurement between 190 and 800 nm.

      J. Planar Chromatogr. 19, 52-57 (2006). TLC and HPTLC of cholesterol, cholic and lithocholic acid, and taurodeoxycholic acid sodium salt on silica gel with methanol - dichloromethane 14, and on RP18 with methanol - water 41 with chamber saturation. Detection by spraying with phosphomolybdic acid solution and placing the plates in a gravity convection oven. The plates were heated to different temperatures from 40 to 120 °C for different periods of time (from 2 to 40 min). Best conditions for sensitive and robust detection on silica gel and RP18 were low derivatization temperatures around 60 °C and long heating times of more than 15 min.
