TLC of extracts of Ruyi Jinhuang Tie ointment on silica gel with 1) n-butanol - glacial acetic acid - water 7:1:2; 2) petroleum ether (30 - 60 ºC) - ethyl formate - formic acid 15:5:1; 3) toluene - ethyl acetate - acetic acid 13:9:1; 4) chloroform - methanol - formic acid 96:3:1; 5) ethyl acetate - methanol - water 100:17:3 and toluene - ethyl acetate - formic acid water 20:10:1; 6) n-hexane - benzene - ethyl acetate 14:3:3. Detection under UV 365 nm and by spraying with 1 % FeCl3 solution in ethanol or with a solution of 5 % p-dimethylaminobenzaldehyde 10 % ethanolic H2SO4 followed by heating at 80 ºC. Identification of the fingerprint. Quantitative determination of berberine chloride by HPLC. The results of three batches of real life samples are given.
Chromatographia 65 (3-4), 245-248 (2007). TLC of dimethyl phthalate, diethyl phthalate, dibutyl phthalate, di(2-ethylhexyl)phthalate (DEHP), benzyl butyl phthalate, diisodecyl phthalate, dimethyl adipate, diethyl adipate, di(2-ethylhexyl)adipate, triethyl citrate, tributyl citrate, tributyl acetyl citrate and n-butyl stearate on inorganic ion-exchanger stannic silicate with toluene - ethyl acetate 10:1 over 12 cm (25 min). Quantification of DEHP by densitometry at 280 nm. Limit of quantitation for DEHP was 0.50 µg/zone and limit of detection 0.05 µg/zone.
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.
