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.
Acta Chromatographica 21 (1), 29-38 (2009). Evaluation of different TLC systems for analysis of 21 amino acids in biological tissues and fluids. Detection by derivatization with ninhydrin reagent, and determination of Rf values by slit-scanning densitometry. The five most suitable systems were cellulose and silica gel plates developed with either 2-butanol - pyridine - acetic acid - water 39:34:10:26 or 2-butanol - pyridine - 25 % ammonia - water 39:34:10:26, and ion exchange plates developed with citrate buffer of pH 3.3. Detection with ninhydrin allowed the identification of all amino acids except for leucine and isoleucine in complex mixtures. Quantification is possible as well if the amino acid of interest is well separated from adjacent components of the mixture. The method is illustrated with example chromatograms on cellulose HPTLC layer showing the identification and separation of amino acids in snail tissue samples.
J. Liq. Chromatogr. Relat. Technol. 36, 2497-2511 (2013). HPTLC evidence of rapid peptidization of L-proline and DL-proline on silica gel with 2-butanol - pyridine - ammonia (25 %) - water 39:34:10:26 and on silica gel plates impregnated with Mn(II) and Cu(II) acetate with dioxane - water 13:7+1 drop 2 % acetic acid. HPTLC enantioseparation of DL-proline was performed with 2-butanol - pyridine - glacial acetic acid - water 15:10:3:12. Detection by dipping into 0.5 % ninhydrin solution in 2-propanol, followed by heating for 2 min at 110 °C. Quantitative determination by absorbance measurement at 340 nm.
Food Chem. 242, 601-610 (2018). Review of recent research on L-theanine, including the use of HPTLC for the rapid quantitative determination in Camellia sinensis and the combination with other non-chromatographic techniques.
of Chromatogr. 2, 138-140 (1984). (Chinese). (A new method of the quantitative determination of proline and hydroxyproline.) TLC of proline and hydroxyproline on silica with butanol- acetic acid - water 4:1:1. Detection by multiple immersion in a) acidified acetone solution of ninhydrin-cadmium, b) a solution of 0.5 % isatin, followed by c) solution of 15 % sodium silicate. Sensitivity 100 ng. Densitometry at 510 nm.
Determination by using autoradio - layer chromatographic recorder.
J. Chromatogr. 391, 343-345 (1987). TLC of N-carbamyl-D, L-tryptophan on silica containing a chiral stationary phase, 2S, 4R, 2'RS-4-hydroxy-1- (2-hydroxydodecyl) proline, and copper(II) with water - methanol system at reduced temperature. Detection by spraying with Ehrlich's reagent and heating at 105 °C for 5 min Sensitivity, 100 mg/mL.
J. Chromatogr. 436, 341-343 (1988). TLC of various amino acids on silica with methanol - chloroform - 3:1. Detection by spraying the plates first with 0.01% fluorescein isothiocyanate in 0.1 M aq. sodium hydroxide solution. After heating at 90 °C for 10 min., the plates are cooled and then sprayed with 0.25 % ninhydrin in acetone. Various different colors are obtained. Detection limit 0.5-1.0 µg.
J. of Medicinal Chemistry 32, 174-179 (1989). TLC on silica with 1-butanol - acetic acid - pyridine - water 5:5:4:1, 2-propanol - 25% NH3 - water 3:1:1, ethyl acetate - pyridine - acetic acid - 5:5:1:3 and butanol - acetic acid - water 4:1:5. Visualization with ninhydrin, fluorescamine and iodine vapor.
