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 Chromatographica 3, 59-69 (1994). TLC of 16 heterocyclic compounds with ring nitrogen atoms on florisil and aluminium oxide with polar solvents. Interpretation of the experimental results in terms of a molecular model of adsorption, by graphical analysis of plots of RM against the logarithm of mole fraction of the polar solvent.
J. Planar Chromatogr. 21, 259-261 (2008). TLC of 6 porphyrins (5,10,15,20-tetra-(4N-pyridyl)porphyrin, 5-(4-acetamidophenyl)-10,15,20-tri-(4N-pyridyl)porphyrin, 5,10-di-(4-acetamidophenyl)-15,20-di-(4N-pyridyl)porphyrin, 5,15-di-(4-acetamidophenyl)-10,20-di-(4N-pyridyl)porphyrin, 5,10,15-tri-(4-acetamidophenyl)-20-(4N-pyridyl)porphyrin, and 5,10,15,20-tetra-(acetamidophenyl)porphyrin) on RP-18 with methanol - chloroform 7:3. Visual detection. The lipophilic properties of the porphyrins were expressed by use of log PRecker, HLB (hydrophilic-lipophilic balance), and HK (determines the percentage contribution to hydrophilicity of one or more functional amido groups (-NH-CO-CH3)).
HPTLC of porphyrines (uro-I-, heptacarboxy-I-, hexacarboxy-I, pentacarboxy-I-, copro-I- and meso-IX-) on RP-18 silica with ethanol – dioxane (1:1) for 15 mm, then with acetonitrile – ammonium acetate buffer pH 4.1 – N-cetyl-N,N,N-trimethylammonium bromide 9:5:5 for 70 mm. Dipping into paraffin – hexane solution for 1 sec, drying and detection under UV 366 nm. Fluorimetric quantification after 1 h.
J. Planar Chromatogr. 17, 388-390 (2004). HPTLC of uroporphyrins I and III, coproporphyrins I and III, and protoporphyrin on silica gel with binary mobile phases prepared by mixing pure esters, ketones, and xylenes with DMSO in proportions from 0 to 100 %. Detection under UV light at 254 nm. The separation of the porphyrins required the presence of DMSO in the mobile phase.
Journal of Natural Products 51, 129-135 (1988). TLC of indole-3-carboxaldehyde and indole-3-acetonitrile on silica with dichloromethane and with dichloromethane - methanol 95:5 and 90:10. Color reaction after spraying with Ehrlich’s reagent.
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.
J. Planar Chromatogr. 20, 365-371(2007). Estimation of retention data by use of correlation equations and physicochemical properties is a useful tool in liquid chromatography. HPTLC of an homologous series of 9 s-triazines on RP-18, cyano-, and amino phase in unsaturated chambers with aqueous solutions of the organic solvents acetonitrile, tetrahydrofuran, and dioxane. After development the dried plates were examined under UV light at 254 nm.
62nd Indian Pharmaceutical Congress Abstract No. F-301 (2010). TLC of brimonidine tartrate on silica gel with methanol – toluene – triethylamine 10:35:2. The hRf value was 48. Quantitative determination by absorbance measurement at 247 nm. The method was linear in the range of 100-600 ng/band. The sample was subjected to different stress conditions (acid, base, oxidative, thermal and photolytic). With the proposed method all the degradation products were well resolved from the drug.
