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. 2, 355-361 (1989). Description of the use of SIMS in the direct analysis of samples separated by TLC (bile acids and diuretics). Discussion of the correct selection of extraction/sputtering solvent, the influences of extraction solvent volume and primary ion beam parameters.
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.
J. Sep. Sci. 33, 3110-3118 (2010). HPTLC of bile acids and their derivatives on 1) RP-18, 2) RP-18W and 3) cyano phase with methanol - water mixtures. The volume fraction of organic solvent in the mobile phase ranged from 70-90 % for (1), 50-70 % for (2) and 45-65 % for (3). Detection by spraying with a solution of manganese chloride in sulfuric acid, followed by heating at 100-120 °C for 10 min. Quantification by absorbance measurement at 254 nm and 365 nm.
) (Chinese). J. Shenyang Pharm. Coll. (Shenyang Yaoxueyuan Xuebao) 6, 197-198 (1989). TLC of bile components on silica with isopentanol - acetic acid - water 1853. Identification by comparing the Rf values with those of standards.
III. Separation on various stationary phases. J. Liq. Chrom. & Rel. Technol. 27, 2613-2623 (2004). TLC of cholic, glycocholic, glycolithocholic, deoxycholic, chenodeoxycholic, glycodeoxycholic, and lithocholic acid on different preparations of silica gel and a mixture of silica gel and Kieselguhr with n-hexane - ethyl acetate - acetic acid in various volume compositions; successful separation was achieved with the compositions 441 and 22215. Detection by 10 % aqueous sulfuric acid followed by heating at 120 °C for 20 min. Densitometric measurement at 250 nm.
J. Planar Chromatogr. 28, 380-385 (2015). HPTLC of taurocholic acid (1), glycodeoxycholic acid (2) and taurodeoxycholic acid (3) in ten Thai edible plants on silica gel with chloroform - methanol - acetic acid 721. Quantitative determination by absorbance measurement at 366 nm. Linearity was in the range of 34-2200 ng/zone for (1), 33-2100 ng/zone for (2) and 30-1900 ng/zone for (3). LOD and LOQ were 10 and 50 ng/zone for (1), 20 and 40 ng/zone for (2) and 10 and 50 ng/zone for (3). The intermediate precision was below 1.2 % (n=6). Average recovery for (1) to (3) was 99, 100 and 100 %, respectively.
J. Chromatogr. 497, 139-146 (1989). TLC of faecal bile acids on silica with isooctane - 2-propanol - acetic acid 30101 for the 1st development and isooctane - ethyl acetate - acetic acid 10102 for the 2nd. Detection by dipping into 0.2% 2,7-dichlorofluorescein ethanol solution. Quantification by fluoro densitometry at 366 nm. Good correspondence between this method and GC.
