(Detection and identification of flunitrazepam (RohypnolR) in urine by TLC.) T+K 61 (3), 74-79, (1994). Sample preparation by acid hydrolysis followed by solid phase extraction (Extrelut); reduction of the nitro group by TiCl3. Chromatography on silica with chloroform - acetone - NH3 60:30:5, post chromatographic derivatization with Bratton-Marshall reagent; detection limit 100-150 ng/mL urine. Advantages over GC/MS: less interference by large concentrations of other drugs; low time requirement.
J. Planar Chromatogr. 10, 133-134 (1997). TLC of thiopentone (5-ethyl-5-(1-methylbutyl)-2-thiobarbituric acid) and butobarbitone, phenobarbitone, pentobarbitone, phenytoin, and quinalbarbitone on silica with hexane - acetone 4:1 with chamber saturation. Detection by spraying with an acidified potassium iodate - starch solution. Preparation of acidified 1% potassium iodate solution by dissolving 1 g potassium iodate in 100 mL distilled water and acidifying with hydrochloric acid; 1% aqueous starch solution; reagent solution: mixing of 20 mL acidified 1% potassium iodate solution and 5 mL starch solution immediately before use.
(Arzneimittelfälschungen). Dtsch. Apoth. Ztg. 140, 63-70 (2000). TLC of anabolic steroid hormones (i. a. metandienone, stanozolol, methyltestosterone, clenbuterol hydrochloride) on silica gel with ethyl acetate - n-hexane 1:1. Evaluation under UV at 254 nm. Detection by spraying with 25 % sulfuric acid in ethanol and heating for 10 min at 1208C until optimum development of the colors of the spots. Simple and fast method.
J. Planar Chromatogr. 25, 108-111 (2012). HPTLC of indole acetic acid (1), indole butyric acid (2), and absisic acid (3) in watermelon seeds exposed to heavy metals on silica gel with cyclohexane - methanol - 2-propanol 4:2:1 +1 drop ammonia. Quantitative determination by absorbance measurement at 230 nm. Limit of quantification was 10 ng/zone for (1) and (2) and 6 ng/zone for (3).
I. Classification procedure by thin-layer chromatography.) Classification of pesticides, hypnotics, psychotropics, narcotics, local anesthetics etc. by their Rf values related to standard markers on silica TLC. The standard markers used: methyl yellow, methyl red, tetrabromophenol phthalein ethyl ester, malachite green and rhodamine B.
Chinese J. Chromatogr. (Sepu) 9, 113-116 (1991). TLC on silica with isopropanol - acetic acid - water 14:1:5. Detection by dipping into a solution of potassium hydroxide in ethanol and heating at 160 °C for 10 min. Quantification of fluoro densitometry at 230 nm. Detection limit 40 ng. The calibration curve was linear over the range of 40 - 350 ng with the correlation coefficient of 0.998.
Part 3. Identification of drugs and their metabolites by PCA of standardized TLC data. J. Planar Chromatogr. 7, 233-241, (1994). Principal components analysis of standardized Rf values of 443 drugs and their metabolites chromatographed with four eluent systems provided a two-component model accounting for 70.8% of the total variance. The "scores" plot enabled either identification, or restriction of the range of inquiry to few candidates. This simple, cheap and fast analytical method is of vital importance in the identification of an unknown drug in cases of overdose intoxication or poisoning, and is particularly valuable in the unaided search for drugs and their metabolites in instances when the substance is very polar and cannot be identified by gas chromatography.
Proc. 9th Internat. Symp. Instr. Chromatogr., Interlaken, April 9.-11., 155-159 (1997). HPTLC of D/L- methadone and L-methadone on diol with toluene - hexane - diethylamine 3:6:1. Detection by derivatization with modified Dragendorff reagent; quantification by densitometry at 254 nm.
