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:

- 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. Planar Chromatogr. 16, 220-226 (2003). TLC of 24 amino acids (i.a. glycine, L-hydroxyproline, DL-alanine, DL-serine, L-proline, L-tyrosine, DL-valine, L-leucine, DL-iso-leucine, DL-nor-leucine, L-lysine monohydrochloride) on silica gel impregnated with micellar copper sulfate solution as stationary phase and a water-in-oil microemulsion as mobile phase. This system has been proposed for selective separation of DL-phenylalanine from other amino acids.
J. Planar Chromatogr. 22, 65-71 (2009). Presentation of two simple and rapid HPTLC methods for early detection of the effects of herbicides using two different groups of plant biomarkers, which were developed as field tests (Herbicide Weed Response test - HWR-Test). Phytochemical changes can be detected before any morphological changes are visible on the plants. These changes are defined as biomarkers and can be detected by HPTLC-screening. After overall identification of the phytochemical biomarker pattern, two different biomarker groups, carbohydrates and amino acids, were detected using modified reagents for color reactions. Evaluation under daylight and videodensitometric analysis of digital images by VideoScan software. The screening method was previously described [H. W. Ravn, M. Hjorth, L. Lauridsen, P. Kudsk, S. K. Mathiassen, L. Mondolot, Bull. Environ. Contam. Toxicol. 75, 236-245 (2005)].
J. Planar Chromatogr. 26, 180-189 (2013). HPTLC of 2,4-dinitrophenyl-5-L-valine amide derivatives of some amino acids (leucine, isoleucine, valine, asparagine, cysteine, tryptophane) L and D-enantiomers on RP-18 with aqueous buffer pH 2.2 (1.47 mM citric acid, 0.06 mM disodium hydrogen phosphate) and acetonitrile 50 %. The statistic evaluation of the migration distance compared with pressurized planar electrochromatography (PPEC) shows similar RSD.
J. Ethnopharmacol. 202, 97-102 (2017). HPTLC of betaine in the roots of Achyranthes aspera on silica gel with methanol – water 9:1. Detection by spraying with Dragendorff's reagent, followed by 10 % ethanolic sulfuric acid and drying at 110 °C for 5 min. Quantitative determination by densitometry at 520 nm. The hRF value for betaine was 36. Linearity was between 1 and 5 μg/band. The intermediate precision was below 2 % (n=6). LOD and LOQ were 0.13 μg/mL and 0.10 μg/mL, respectively. (Note: The reported LOD and LOQ do not make sense, as LOD is higher than LOQ.)
II. Problems in the choice of the solvent system. Proc. Intern. Symposium on TLC with special Emphasis on OPLC, Szeged, 94-95 (1984). OPLC (OPTLC) of beta-amino-isobutyric acid on silica with chloroform - butanol- DMF - acetic acid 91:2:2:1. Detection with ninhydrin reagent. Densitometry. Separation of urine constituents for the purpose of determining beta-amino-isobutyric acid (a possible tumor maker).
J. Chromatogr. 355, 354-357 (1986). Enantiomeric HPTLC separation of racemic mixtures of amino acids on RP-18 plates impregnated with copper(III)complexes of chiral ligands of the type AA-NN-n. In these ligands two L-amino acids are joined via an amide bond by ethylene and trimethylene bridges. As solvents, mixtures of acetonitrile - water at different pH are used. Also two-dimensional HPTLC of Dans-amino acids with 1) water - acetonitrile 7:3 and 2) water -acetonitrile 58:42, pH 7.5, after treatment with the Cu(II)-Phe-NN-2 complex (4 mM).
Acta Pharmaceutica Jugoslavica 36, 371-381 (1986). TLC on silica with ethyl acetate - benzene 2:1. Detection by spraying with ninhydrin, benzidine and silver nitrate.
J. Liquid Chrom. 10, 1299-1325 (1987). Study of the influence of e.g. organic matter, saline and alkaline salts, cations and pH on the mobility of mono-, dicarboxylic, basic and aromatic amino acids using soil thin-layer chromatography. Discussion of mobility in terms of Rf values of amino acids under different treatments.
