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.

J. Agric. Food Chem. 38, 2164-2168 (1990). TLC of the unsaponifiable fraction (containing sterols, triterpenes, tocopherols, hydrocarbons) on silica with petrol ether (60-80°) - ether 1:1; detection by spraying with 50% sulfuric acid and heating at 115 °C for 10 min. Quantification after elution via gravimetry.

Presentation of results obtained by one-dimensional (displacement) and two-dimensional (elution - displacement) TLC and description of the use of pilot systems for determining the optimum conditions for displacement TLC.
Analyst 119, 2655-2658 (1994). TLC of 40 hormones on silica with chloroform - acetone 9:1, and cyclohexane - ethyl acetate - methanol 117:78:11. Detection by spraying with 10% sulfuric acid in methanol and heating at 95 °C for 10 min. Visualization under UV 366 nm. Detection limit were given. The method enables screening of 39 hormones illegally injected.
J. Liq. Chromatogr. Relat. Technol. 31, 2673-2685 (2008). TLC of dehydroepiandrosterone on silica gel with chloroform - acetone 17:3 with chamber saturation for 30 min. Detection by dipping into 0.05 % aqueous solutions of visualizing agents (methylene violet, gentian violet, janus blue, methylene blue, malachite green, rhodamine B) and methanolic chloramine T/methanolic sulfuric acid solution. Quantitative determination by densitometry at 200 nm (before derivatization and for methylene violet), 657 nm (gentian violet), 487 nm (janus blue), 488 nm (malachite green), 580 nm (rhodamine B), and 361 nm (chloramine T).
