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.
Anal. Letters 28, 1305-1306 (1995). HPTLC of 12 synthetic dyes, eluted in an XAD-2 column with acetone, methanol and water, on silica with i-propanol - n-propanol - n-butanol - NH3 - water 8:4:4:2:1. Quantification by densitometry at the maximum wavelength of the 12 colorings. Detection limit 4 - 10 ng/spot.
J. Planar Chromatogr. 16, 276-279 (2003). Study of the effects of eluent modifications TLC of 9 frequently used water-soluble food dyes (tartrazine, sunset yellow FCF, quinoline yellow FCF, amaranth, ponceau 6R, erythrosine, indigo carmine, brilliant blue FCF, brilliant black BN) on RP-18 with ammonium sulfate solutions (0.1, 0.5, and 1.0 mol/l) in water - organic modifier (ethanol or acetone) of widely variable composition.
of Chromatogr. A 1231, 59-65 (2012) Reversed-phase HPTLC of lutein, lycopene and beta-carotene standards on RP-18 (pre-washed by development with dichloromethane – methanol 1:1) with methanol – acetone 1:1 with 0.1 % of 2-tert-butylhydroquinone. The hRf value was 4 of lutein esters, 24 of beta-carotene, 32 of lycopene, and 68 of lutein. Quantitative determination of lutein by densitometry at 450 nm. The repeatabilities were %RSD = 3.4, 1.3 and 1.6 at levels of 5 ng, 15 ng and 25 ng, respectively (n = 6). The calibration curve was best fit with a polynomial function in the range of 5-30 ng. The LOD was 1.5 ng, the LOQ 5 ng. With these chromatographic conditions also dietary carotenoids lutein esters, lycopene, free lutein and ß-carotene from food supplements were identified. It was shown that the standards remain stable on the plate for 1 h after chromatogram development.

Measuring the visible absorption spectra in the range of 370-700 nm by scanning densitometry with its maximum absorption wavelength at 455 nm.
