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

CBS 114, 9-10 (2015). HPTLC of phosphodiesterase type 5 inhibitors Viagra (sildenafil), Levitra (vardenafil), Cialis (tadalafil) and their analogs (hydroxyacetildenafil, homosildenafil, thiohomosildenafil, acetildenafil, acetaminotadalafil, propoxyphenyl, hydroxyhomosildenafil, hydroxyhomosildenafil, and_x000D_
hydroxythiohomosildenafil) on silica gel with t-butyl methyl ether – methanol – 28 % ammonia 20:2:1 with chamber saturation, migration distance 70 mm. Detection under UV 254 and 366 nm. Densitometric evaluation by absorbance measurement at 232 nm. Identification of the substances based on their hRf values and distinctly different UV spectra.
J. AOAC Int. 100, 414-421 (2017). HPTLC of two binary mixtures containing pyridoxine hydrochloride (1) with either cyclizine hydrochloride (2) or meclizine hydrochloride (3) on silica gel with dichloromethane – acetone – methanol 14:2:1. Quantitative determination by absorbance measurement at 220 nm. The hRF values for (1-3) were 7, 25 and 80, respectively. Linearity was in the range of 0.2-5 μg/zone for (1) and 0.2-4 μg/zone for (2) and (3). The LOD and LOQ were 60 and 190 ng/zone for (1), 50 and 170 ng/zone for (2) and 60 and 170 ng/zone for (3), respectively. The intermediate precision was <2 % (n=3). Average recovery rate was 99.9 % for (1) and (3) and 100.1 % for (2).

J. Planar Chromatogr. 31, 477-487 (2018). HPTLC of thiocolchicoside on silica gel with toluene – acetone – water 3:15:2. Quantitative determination by absorbance measurement at 370 nm. The hRF value for thiocolchicoside was 53. Linearity was between 100 and 500 ng/zone. LOD and LOQ were 4 and 12 ng/zone. The intermediate precision was <2 % (n=3). Recovery was between 99.4 and 101.7 %.
