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

Biochem. Biophys. Res. Commun. 478, 1403-1408 (2016). Centrifugal TLC of xanthorrhizol in the rhizomes of Curcuma xanthorrhizza on silica gel with hexane mixed with increasing ratios of chloroform. Concentric spherical bands of the separated compounds were monitored under UV 254 nm and 366 nm on the rotor. When a single band came to the edge of the rotor, the eluate was collected.
J. Chromatogr. Sci. 55 (9), 954-960 (2017). Presentation of a simple, cost-effective and rapid stability-indicating assay for densitometric quantification of methyltestosterone, a synthetic testosterone derivative commonly used for the treatment of testosterone deficiency in males, in pharmaceutical formulation. TLC of methyltestosterone on silica gel with hexane – acetone 13:7. Quantitative determination by densitometry at 254 nm in absorbance mode. Evaluation via peak areas using linear regression. The LOD and LOQ were 2 and 6 ng/zone, respectively. Investigation of the degradation of methyltestosterone by applying various stress conditions such as hydrolysis under acidic, basic and neutral conditions, heating in anhydrous conditions and exposure to light. Good separation of the degraded products caused by photodegradation, acidic and basic hydrolysis, and identification of acid degraded product as 17,17-dimethyl-18-norandrosta-4,13(14)-dien-3-one by spectroscopy. Explanation of the reactivity of methyltestosterone under applied stress conditions by quantum chemical calculations. The developed method proved to be repeatable, selective and accurate for quantification of methyltestosterone and can be employed for routine analysis.
