Marine Drugs 21(1), 2 (2023). Samples were methanol extracts of cultivated marine bacteria Thalassomonas actiniarum, T. viridans and T. haliotis (Colwelliaceae), as well as cholesterol, cholic acid, and deoxycholic acid as standards. TLC on silica gel with n-hexane – ethyl acetate – methanol – acetic acid 20:20:5:2. After drying at room temperature, visualization by spraying with phosphomolybdic acid (10 % in ethanol) and heating with a heat-gun. For isolation of cholic acid (hRF 80), present in all samples, preparative TLC on silica gel with the same mobile phase, the corresponding band was scraped off with a surgical blade and extracted with methanol overnight. The isolated cholic acid was identified by LC-MS.
J. Planar Chromatogr. 33, 271-279 (2020). Two-dimensional HPTLC of cholic, ursodeoxycholic, chenodeoxycholic, deoxycholic, and lithocholic bile acids on silica gel with 0.0001 M cetylpyridinium chloride at pH 9 with the addition of aliphatic alcohol modifiers 4 % 1-butanol (direction II) and 0.6 % 1-pentanol (direction II). Detection by drying the plate for 2-3 min in the oven at 120 ºC, followed by spraying with 8 % sulfuric acid in ethanol. Qualitative determination under UV light at 365 nm.
J. AOAC Int. 102, 708-713 (2019). TLC of snake bile in 20 species from three families (Elapidae, Colubridae, and Viperidae) on silica gel with xylene – isopropanol – methanol – glacial acetic acid – water 80:40:30:20:3. Detection by spraying with a 10% sulfuric acid ethanol solution, followed by heating at 105 ºC. Qualitative identification under UV light at 366 nm. TLC coupled with quadrupole–time-of-ﬂight–MS analysis of each zone was used for compound identification and evaluation.
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 20:20:5:2. Detection by dipping for 15 s in sulfuric acid - methanol 1:19, 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 1:4, and on RP18 with methanol - water 4:1 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.
J. Shenyang Pharm. Coll. (Shenyang Yaoxueyuan Xuebao) 6, 197-198 (1989). TLC of bile components on silica with isopentanol - acetic acid - water 18:5:3. Identification by comparing the Rf values with those of standards.
