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. Chromatogr. A 1533, 208-212 (2018). Development of a rapid method for the determination of caffeine, theobromine and theophylline in Mate beer and Mate soft drinks. Sample preparation through filtration followed by degassing, dilution with acetonitrile in the case of Mate beers for protein precipitation and centrifugation. HPTLC of the extracts on silica gel with acetone – toluene – chloroform 4:3:3, detection and quantification by densitometry at UV 274 nm. The LOD and LOQ were 1 and 4 ng/zone for caffeine, theobromine and theophylline, respectively, and recoveries were close to 100%. Demonstration of the method by applying to the analysis of the concentrations of three methylxanthines in Mate beers as well as Mate beers and Mate soft drinks available from the market proved to be sensitive, accurate and reliable.
J. of Medicinal Chemistry 32, 1547-1551 (1989). TLC of nucleosides on silica with ethyl acetate - ethanol 6:1 and 9:1. Detection by UV and with 10% sulfuric acid in methanol followed by heating.
