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. The saved items can be printed to PDF using the print function of your web browser.
J. Liq. Chromatogr. Relat. Technol. 33, 922-935 (2010). TLC and HPTLC of 22 different pyridinium aldoximes on silica gel with water - acetonitrile - acetic acid 8:1:1, water - acetone - acetic acid 8:1:1, and acetone - 50 mM aqueous sodium acetate 1:4 using unsaturated and saturated vapor phase as well as OPLC. Detection under UV 254 nm.
J. Liq. Chromatogr. & Relat. Technol. 30, 557-574 (2007). TLC of trigonelline (3-carboxy-1-methylpyridinium hydrochloride) and degradation products on silica gel with n-propanol - methanol - water 4:1:4 in a twin-trough chamber. Quantitative determination by absorbance measurement at 269 nm.
J. Liq. Chromatogr. Relat. Technol. 33, 1038-1046 (2010). TLC of nicotinic acid and methyl, ethyl, isopropyl, butyl, hexyl, and benzyl nicotinate (heated for 1 to 7 h at 120 °C) on silica gel pre-washed with methanol using methanol - benzene (for nicotinic acid) and acetone - hexane 2:3 for nicotinic acid esters. Quantitative determination by densitometric absorbance measurement at the respective absorption maximums (263 nm for nicotinic acid, 220-222 nm for nicotinic acid esters). The hRf of nicotinic acid was 44, and of methyl, ethyl, isopropyl, butyl, hexyl, and benzyl nicotinate 48, 46, 51, 54, 56, and 44, respectively.)
62nd Indian Pharmaceutical Congress Abstract No. F-389 (2010). TLC of amlodipine and telmisartan on silica gel with chloroform – methanol – toluene 10:7:3. The hRf values were 23 and 75 for amlodipine besylate and telmisartan respectively. Quantitative determination by absorbance measurement at 238 nm. The sample was also analysed by spectophotometry and the results by both methods were comparable.
62nd Indian Pharmaceutical Congress Abstract No. F-256 (2010). TLC of amlodipine besylate and enalapril maleate on silica gel with toluene – isopropanol – glacial acetic acid – methanol 50:20:6:5. The hRf values were 15 and 23 for amlodipine besylate and enalapril maleate, respectively. Quantitative determination by absorbance measurement at 223 nm.
62nd Indian Pharmaceutical Congress Abstract No. F-254 (2010). TLC of amlodipine besylate and telmisartan on silica gel with ethyl acetate – methanol – 25 % ammonia – glacial acetic acid 75:15:1:2. The hRf value was 34 and 60 for amlodipine besylate and telmisartan, respectively. Quantitative determination by absorbance measurement at 226 nm. The linearity was in the range of 500-6000 ng/band for amlodipine and 1000-8000 ng/band for telmisartan. The sample was subjected to various stress conditions and all the degradation products were well resolved from the pure drugs. The method can be used for stability studies.
Budapest Chromatography Symposium June 13, 1985. Optimization of TLC separation of biologically active acridine glycosides; more than 50 solvent systems and 10 "straight" and reversed-phase layers investigated. Best results with MERCK silica gel and isobutanol - ethanol - water - NH3 55:20:20:5.
Chromatographia 20, 249-252 (1985). HPTLC of methyl nicotinate on silica with ether - dichloromethane - hexane 5:3:2. Detection by spraying with 0.1 % solution of the ammonium salt of 8-anilino-naphthalene-1-sulfonic acid in water. Quantification by densitometry at 263 nm. 1) 3-pyridine carboxaldehyde was used as internal standard. 2) After quantification of methyl nicotinate the same plate was used for the identification of the cream base excipients with methanol - chloroform 3:2.
