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.

TLC of glycine, valine, norvaline, hysine, phenylalanine, tyrosine, cystine, homocystine, aspartic and glutamic acid on silica with butanol - acetic acid - water 4:1:1, 4:1:5 and butanol - acetic acid - pyridine - water 15:3:12:10. Visualization under UV and by exposing to iodine vapor.
Analyst 119, 2655-2658 (1994). TLC of 40 hormones on silica with chloroform - acetone 9:1, and cyclohexane - ethyl acetate - methanol 117:78:11. Detection by spraying with 10% sulfuric acid in methanol and heating at 95 °C for 10 min. Visualization under UV 366 nm. Detection limit were given. The method enables screening of 39 hormones illegally injected.
J. Planar Chromatogr. 20, 423-427 (2007). TLC of 8 essential amino acids (L-lysine, L-valine, L-isoleucine, DL-threonine, L-methionine, L-leucine, DL-phenylalanine, DL-tryptophan) on silica gel with 17 mobile phases, of which the mixed aqueous surfactant solution Triton X-100 (0.001 mM) - sodium dodecyl sulfate, 0.081 mM - acetone 1:1:5 was identified as the best mobile phase for specific separation of lysine. Visualization by spraying with 0.3 % ninhydrin in acetone. Limit of detection was 0.5 µg/zone.
J. Planar Chromatogr. 23, 255-259 (2010). Synthesis of a new ligand by anchoring anthracene to L-methionine. The ligand allows identification of amino acids on TLC plates based on distinguishable colors. A theoretical calculation (Hartree–Fock) was performed to investigate interaction of the ligand with the amino acids. TLC of 22 amino acids on silica gel with n-propanol - water 7:3. Detection by spraying with 0.01 % anthracenylmethyl L-methionine in acetone, followed by drying and spraying with 0.25 % ninhydrin in acetone. After drying and heating at 110 °C for 10 min the zones were evaluated visually. Detection limits were between 1 and 200 ng/zone.
J. Planar Chromatogr. 27, 210-216 (2014). HPTLC of 5-hydroxy-L-tryptophan (1), 5-methyltryptamine (2), L-tryptophan (3) and melatonin (4) on silica gel with propan-2-ol - 25 % ammonia - water 8:1:1. Quantitative determination by absorbance measurement at 280 nm. The hRF values for (1) to (4) were 47, 79, 53 and 85, respectively. Linearity was in the range of 48-720 µg/zone for (1), 38-646 µg/zone for (2), 100-2000 µg/zone for (3) and 108-1737 µg/zone for (4). The intermediate/interday/intra-day precisions were below 3 % (n=5). The LOD and LOQ were 16 and 49 ng/zone for (1), 40 and 122 ng/zone for (2), 116 and 352 ng/zone for (3) and 145 and 439 ng/zone for (4). Mean recovery was between 97.4 and 100.1 % for (1) to (4).
