Cumulative CAMAG Bibliography Service CCBS
Our CCBS database includes more than 11,000 abstracts of publications. Perform your own detailed search of TLC/HPTLC literature and find relevant information.
The Cumulative CAMAG Bibliography Service CCBS contains all abstracts of CBS issues beginning with CBS 51. The database is updated after the publication of every other CBS edition. Currently the Cumulative CAMAG Bibliography Service includes more than 11'000 abstracts of publications between 1983 and today. With the online version you can perform your own detailed TLC/HPTLC literature search:
- Full text search: Enter a keyword, e.g. an author's name, a substance, a technique, a reagent or a term and see all related publications
- Browse and search by CBS classification: Select one of the 38 CBS classification categories where you want to search by a keyword
- Keyword register: select an initial character and browse associated keywords
- Search by CBS edition: Select a CBS edition and find all related publications
Registered users can create a tailor made PDF of selected articles throughout CCBS search – simply use the cart icon on the right hand of each abstract to create your individual selection of abstracts. You can export your saved items to PDF by clicking the download icon.
Acta Pharmaceutica Jugoslavica 39, 225-231 (1989). TLC on cellulose with propanol - water 7:3. Visualization under UV; densitometric absorbance at 295 nm.
Arzneim.-Forsch. 39, 328-224 (1989). TLC of tiropramide and metabolites on silica with butanol – acetic acid – water 5:2:1, isoamyl alcohol – acetone – water 5:2:1 and chloroform – ethyl acetate 7:3. Detection under UV 254 nm; identification and quantification by scintillation measurement.
Magyar Kémiai Folyóirat, 97, 196-205 (1991). TLC of 2-methylenecephalosporins and 2-spirocyclopropyl-cephalosporins on silica with benzene - ethyl acetate 1:1, benzene - ethyl acetate - acetic acid 7:3:1, hexane - ethyl acetate 1:1, chloroform - ether 3:2 or 9:1. Detection under UV and by spraying with ammonium molybdate.
J. Planar Chromatogr. 5, 184-191 (1992). RM values of some basic drugs (used mainly against Parkinson’s disease) and related compounds have been measured by RPTLC with a variety of ion pair reagents in the mobile phase or stationary phases. Retention and separation selectivity were readily controlled by changes in the eluent pH, methanol (modifier) content, or type and concentration of the ion pair reagent. - The strongest effect on the retention of the compounds was obtained when ion pair reagent was incorporated into the stationary phase.
Teil 2 - Simple thin-layer chromatographic identification of active principles in finished products. Part 2. Pharm. Ind. 55, 259-267 (1993). TLC of acetylsalicylic acid on silica with ethyl acetate - methanol - acetic acid 80:19:1. Detection under UV 254 and by exposure to iodine vapor. TLC of paracetamol and of ibuprofen on silica with toluene - acetone - formic acid 50:48:2 and 70:28:2, respectively. Detection under UV 254 and by exposure to iodine vapor. TLC of a series of other drugs from the Essential Drug List were reported, which allow a fast and relatively sure basic quality control in finished products.
J. Planar Chromatogr. 7, 458-460 (1994). HPTLC on silica with chloroform - acetic acid - toluene - methanol 8:1:1:1, previously saturated for 1 h. Quantification by densitometry at 366 nm. Detection limit 0.2 ng. A simple, highly sensitive, and fast HPTLC method.
J. Planar Chromatogr. 9, 185-188 (1996). HPTLC of buspirone, gepirone, ipsapirone, zalospirone and their resp. impurities on silica with the upper layer of n-butanol - acetic acid - water 4:1:2, isopropanol - butanone - NH3 50:50:1, or isopropanol - acetone - NH3 70:30:1; quantification by densitometry at 237 nm. Detection of a specific impurity by spraying with hydroxylamine solution. - Detection limits of a few nanograms were obtained at a signal-to-noise ratio 3:1. The relative standard deviation values for the main components and related impurities were between 2.2 and 3.4%.
J. Planar Chromatogr. 9, 382-387 (1996). TLC of oxazepam, diazepam, nitrazepam, chlordiazepoxide, and medazepam on silica with 6 different mobile phases and on RP-18 with 7 different mobile phases. Visualization under UV 254 nm, by spraying with 2% ethanolic dinitrobenzene solution and after drying with 10% ethanolic sodium hydroxide solution, by exposure to HCl vapor, by placing the plate into a cooled TLC chamber with nitrous gases, or by spraying with Dragendorff's reagent. Quantification by densitometry. Best separation on RP-18 with methanol - pH 3.0 acetate buffer 3:1, detection under UV 254 nm. Detection limits for diazepam and nitrazepam 0.005 mg/mL.
