J. Liquid Chromatogr. 18, 837-848 (1995). Description of the essential steps of displacement TLC and its applications for the separation of ecdysteroids. Discussion of the conditions of displacement TLC for plant ecdysteroids including the optimization of mobile phase composition, mobile phase flow rate, and preelution before displacement development.
Neighbouring group participation in hypobromous acid addition to 19-substituted 5 alpha-cholest-1-enes and in acid cleavage of their epoxy analogs. Coll. czechoslov. chem. comm. 47, 3062-3076 (1982). TLC of cholestane derivatives on silica with a) heptane-ether 4:1, b) petrol ether - ether - acetone 90:5:5, c) benzene - ether 1:1, 4:1 and 7:3. Quantification after elution.
J. Chromatogr. 257, 157-161 (1983). TLC of various phytoecdysones on silica with the lower layer of chloroform - methanol -water 13:7:4. Detection by UV 254 nm. TLC is used in order to select the solvent system for droplet countercurrent chromatography (DCCC).
J. High Resol. Chromatogr. 9, 285-288 (1986). Presentation and discussion of equations for predicting analysis time in thin-layer chromatography as a function of spot separation, solvent velocity constant, DELTA Rf and Rf
J. Chromatogr. 452, 377-398 (1988). Evaluation of the chromatographic properties of about 100 sterols, select steroids of plant origin and triterpenoids by TLC or argentation TLC and other techniques. Visualization of TL Chromatograms by spraying with 50% methanolic sulfuric acid and heating at 60°C. Discussion of the utility of each methodology.
J. Planar Chromatogr. 4, 207-212 (1991). HPTLC of mixtures of most frequently used anabolic compounds (mixture A: estradiol benzoate, trenbolone acetate, chlormadinone acetate, ethinylestradiol, diethylstilbestrol; mixture B: nortestosterone decanoate, testosterone propionate, methyltestosterone, medroyprogesterone acetate, zeranol; mixture C: stanozolol, boldenone, methylboldenone, chlortestosterone acetate) on silica gel RP-18 resp. CN with 7 different eluents. Detection by dipping into a 5% ethanolic solution of sulfuric acid for 30 sec., acceleration of fluorescence induction by heating the plates at 95 °C for 10 min; visualization under UV 366 nm and under visible light (also two-dimensional separation. Simple, relatively quick routine TLC procedure.
Chromatographia 39, 97-102 (1994). HPTLC of several steroid hormones on NH2-bonded silica with 1) chloroform - ethanol - formic acid 5:1:1, 2) chloroform - methanol 95:5, 3) chloroform - 1-propanol - formic acid 50:10:5. Detection by heating at 150 °C for 3 - 4 min. Discussion of the qualitative analysis of selected steroid hormones, i.e. the pharmacologically relevant compounds cortisone and hydrocortisone, estrodiol, estrodiol benzoate, estriol, estrone, methyltestosterone, pregnandiol and triol, pregesterone and Reichstein's S.
LC-GC Europe 14, Issue 10, 626-631 (2001). TLC of 20-hydroxyecdysone on silica gel, pre-washed with methanol. Different mobile phases are investigated, the mixture of chloroform — methanol — benzene 25:5:3 was used for quantification. Densitometry at 254 nm. TLC of ecdysteroids under the same conditions, detection at 254 nm, in white light and at 366/>400 nm (fluorescence) after spraying with a vanillin-sulphuric acid reagent. Identification was facilitated with two-dimensional TLC, displacement TLC (D-TLC) and forced flow TLC (FF-TLC). Comparison with HPLC.
