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.
J. Planar Chromatogr. 13, 217-220 (2000). TLC of L-lysine, L-threonine, L-homoserine on silica gel with 2-propanol - 25 % NH3 11:9, 1-propanol - acetone - water - 25 % NH3 25:25:7:6 and 2-propanol - ethyl acetate - 25 % NH3- water 40:40:3:50. Visualization by dipping in a 1 % ninhydrin solution in acetone. TLC of vitamin B12 and its derivatives on aluminium oxide with 2-methylpropan-1-ol - 2-propanol - water 3:2:2. - Quantitation by densitometry at 500 (for ninhydrin-amino acid complexes) resp 548 nm (for cobalamines).
J. Liq. Chromatogr. & Relat. Technol. 29, 2153-2158 (2006). TLC of a bacterial vitamin B12 extract and vitamin B12 on silica gel with 2-propanol - 28% ammonia - water 7:1:2 in the dark. After drying extraction and determination of the B12 activity by a microbiological B12 assay method.
J. Planar Chromatogr. 22, 211-215 (2009). TLC of fat soluble vitamins (ergocalciferol, cholecalciferol, (+/-)-alpha-tocopherol, tocopherol acetate, retinol, retinol acetate, retinol palmitate, menadione, and phytonadione) on RP-8 and RP-18 (prewashed with methanol) with methanol - water in different volume proportions, with chamber saturation for 20 min at ambient temperature. Determination of hRf values by densitometry. Linear relationships were obtained between the RM values of the fat-soluble vitamins and the volume fraction of methanol in the mobile phase.
(Hungarian) (Changes in the content of vitamin C of quickfrozen strawberry cream during its storage.) TLC of ascorbic acid, dehydroascorbic acid EDAS osazone) on silica with chloroform - ethanol 96:4.
J.A.O.A.C. 68, 547-548 (1985). Estimation of niacin and niacinamide on silica with water; detection by UV.
Chinese Anal. Chem. 15, 939-941 (1987) (Fenxi Huaxue). TLC on silica with benzene - acetic acid - ethanol - water 70:25:10:3. Detection under UV 365 nm. Quantification by densitometry at 255 nm.
International Laboratory News, February, 8A-8B (1994). HPTLC of clenbuterol in various matrices on silica in horizontal developing chamber from both sides with ethyl acetate - methanol - acetic acid 8:1:1 with chamber saturation. Derivatization by spraying with Bratton-Marshall reagent (first 1% sodium nitrite in 1 N HCl, then 0.4% N-(1-naphthyl)-ethylenediamine dihydrochloride in methanol). Quantification by densitometry (absorbance) at 525 nm. Detection limit 2.5 ng; determination limit 10 ng. Further betablockers can be detected with this method, like atenolol at hRf 8, salbutamol at 14, propranolol at 25, clenbuterol at 40 and labetalol at 44. Sample preparation includes deproteinization, defattening and final extraction from an alkaline aqueous phase. Very fast method - chromatography of 18 resp. 36 samples within 10 min.
