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.

Establishment of hRf values decreasing when the oxygen atom in b-diketonato ligand substituted by a less electronegative sulfur atom, and the substitution of acac ligand resulting in hRf value decreasing, and a linear dependence between RM values of the complexes and the number of acac ligands substituted by phacphSac ligands.

Calculation of seventeen structure parameters of the ginsenosides for QSRR study, including topologic indices and physicochemical properties. A novel parameter "E" was presented according to the differences of the parent substances the ginsenosides are composed of. Selection of Aw, 8B and E among the parameters by optimization, which were employed in the derived multi-parameter regression equation. Discussion of the relationships between the retention and the molecular structure of the compounds.
