Detection by UV 365 nm. Determination of the eluates by UV spectrometry at 265 nm for praziquantel and 320 nm for the impurities.
Chinese J. Pharm. Anal. 8, 27-29 (1988) (Yaowu Fenxi Zazhi). TLC on silica with chloroform - ethanol 100:4 or 100:6. Quantification after elution with chloroform - ethanol 15:1 by UV spectrophotometry at 301 nm.
J. Chromatogr. 439, 441-444 (1988). Two-dimensional TLC of 37 steroid hormones and metabolites on silica with dichloromethane - methanol - water 225:15:1.5 for the first direction and petrol ether (37-55°C) - ether - acetic acid 48:50:2 for the second. Detection under UV or by spraying with antimony trichloride and heating at 130°C for 5-10 min.
Anal. Letters 21, 2227-2240 (1988). TLC of sulfonamide chemotherapeuticals on silica with chloroform - methanol 9:1. Quantification by densitometry at 285 nm.
(Determination of drugs in urine: Conformity and divergence of methods.) Bull. Soc. Sui. Chim. Clin. 31/3, 49-55 (1990). TLC methods developed for drug screening in human urine from a single 30 mL sample: opiates species, methadone amphetamines, barbiturates; cocaine and benzoylecgonine; benzodiazepines; and tetrahydrocannabinol carboxylic acid. Separation on HPTLC plates and identification with proper reagents. Intermethod comparisons of results with enzyme immuno assay technique (EMIT) show very good agreement. Lower limits of detection and better reliability make TLC a good complement to EMIT. References to individual methods cited.
Pharm. Anal. (Yaowu Fenxi Zazhi) 11, 150-153 (1991). TLC of geniposide on silica with ethyl acetate - acetone - acetic acid 3:2:1. Quantification by densitometry at 240 nm.
Chinese J. Pharm. Ind. (Zhongguo Yiyao Gongye Zazhi) 22, 174-175 (1991). TLC of timolol and its three intermediates on silica with different solvent systems, e.g. ethyl ether – tetrahydrofuran 1:15. Detection under UV light.
Chinese J. Pharm. Anal. (Yaowu Fenxi Zazhi) 13, 33-34 (1993). TLC of antipyrine and aminopyrine on silica with benzene - acetone 2:1. Quantification by densitometry at 260 nm.
