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.

Detection reagents which were used: a) silver-acetate 1 % in water, b) mercuric sulfate solution, c) diphenylcarbazone 0.01 % in acetone / water, d) 0.5 % sulfuric acid, e) iodoplatinate, f) iodine-potassium iodide reagent, all acc. to Kaistha, Jaffe et al., J. Pharm. Sci. 61, 679 (1972).
Phytochem. Anal. 17, 394-397 (2006). HPTLC of phyllanthin and hypophyllanthin from Phyllantus species, e.g. Phyllantus amarus, on silica gel with hexane – acetone – ethyl acetate 37:6:4. Detection by spraying with vanillin in concentrated sulfuric acid and ethanol. Quantitative determination by absorbance measurement at 580 nm. Recovery of phyllanthin is 98.7 % and of hypophyllanthin 97.3 %.The method was validated and the peak purities and limits of detection and quantification were determined.
