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.
CBS 111, 5-6 (2013). HPTLC of caffeine, taurine, and arginine in shampoo samples extracted with isopropanol, on silica gel over 50 mm with isopropanol - n-heptane - water 7:3:1 for caffeine and isopropanol - water 4:1 for arginine and taurine. Detection under UV 254 nm (caffeine) and after spraying with ninhydrin reagent under white light (arginine and taurine). Quantitative absorbance measurement at UV 254 nm for caffeine and UV 600 nm for arginine and taurine. The hRF of caffeine was 54. Precision (%RSD) for the polynomial calibration of caffeine was 3.9 % (n=3). The hRf of taurine was 24. Arginine remained at the start position under these conditions. The content of taurine and caffeine found in shampoos corresponded to the usual amount of 0.1 % active ingredient in a formulation.
Proc. Intern. Symposium on TLC with special Emphasis on OPLC, Szeged, 62-63 (1984). OPLC (OPTLC) of amino acids on silica with chloroform - CCl4 -MEK -propanol -methanol - acetic acid 30:30:20:30:15:2. Detection by UV 366 nm. Quantification by densitometry.
(Separation of derivatized amino acids on HPTLC-precoated plates with cyanomodification.) GIT 2, 105-108 (1986). New cyano-modified HPTLC precoated plates demonstrated by the separation of PTH-, DNP- and DNS amino acids. Layers are suitable for employing straight phases as well as RP-phases and ion pair reagents.
J. Chromatogr. 355, 273-280 (1986). Two-dimensional TLC of 7 aminobutyric acids on cellulose with 1) pyridine - dioxane -25 % NH3 - water 35:35:15:15 and 2) butanol - acetone - acetic acid - water 35:35:7:23. Detection by spraying with ninhydrin and heating at 80 °C. Also GLC analysis.
Anal. Chim. Acta 196, 259-265 (1987). TLC of the products of enzyme reaction of lysine, ornithine and glutamic acid decarboxylases on silica with acetone - 33% aqueous dimethyl amine - isopropanol 18:25:56. Evaluation by radioactivity linear analyser connected to a computer based on a simple modification of the integrated Michaelis-Menten equation. Direct fit of the experimental points to the equation by iterative techniques, the validity of which is tested on the simulated data.
J. Chromatogr. 448, 11-30 (1988). TLC of proteinogenic and non-proteinogenic amino acids, dipeptides and a-hydroxy acids. Separation of the enantiomers, without derivatization, on a chiralplate. Quantification by densitometry. Determination of the respective enantiomers at trace levels (0,25%). Detection limits: 0.1% of the minor enantiomer. Other examples from the field of +-methyl, N-alkyl and halogenated amino acids.
J. of Medicinal Chemistry 32, 445-449 (1989). TLC of amino acids on silica with chloroform - methanol - acetone - water 70:30:6:3, chloroform - methanol - acetone - water - ethyl acetate 35:15:3:1. 5:1, chloroform - methanol 90:10, ethyl acetate - pyridine - acetone - water 60:20:6:11 or 40:20:6:11, ethyl acetate - pyridine - acetone - water 50:20:6:11. Visualization under UV with iodine vapor, ninhydrin or Ehrlich’s reagent.
