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. Chromatogr. 519, 171-178 (1990). TLC of 3-hydroxypyridin-4-ones on RP-18 silica with acetic acid - ethyl acetate - hexane - tetrahydrofuran 51:181:101:167, also with same solvent containing 10 mg CPO 94 per 100 mL. Comparison with HPLC. Investigation of the chromatographic behavior in both systems, and discussion of the mechanism. The TLC method is suitable for routine analysis of the compounds in biological matrices.
J. Planar Chromatogr. 4, 333-334 (1991). TLC separation of pyridine, g-picoline, pyrazine, quinoxaline quinoline, their dimers and derivatives on silica with carbon tetrachloride - ethanol - acetone 50:1:2. Detection by spraying with Dragendorff’s reagent and intrinsic color.
J. Planar Chromatogr. 14, 291-295 (2001). TLC of 36 4-benzylthio derivatives of 2-pyridinecarbothioamide and 2-pyridinecarbonitrile on silanized silica gel (impregnation by overnight (15.5 h) development with diethyl ether - silicone oil 19:1) with phosphate buffer of pH 7.4 or 3.0 or 5% ammonia as aqueous component of the mobile phase and acetone or methanol as organic modifier. Visualization at 254 nm.
J. Liq. Chrom. & Rel. Technol. 25, 1515-1520 (2002). HPTLC of nicotinic and iso-nicotinic acid derivatives (3- and 4-[N-4-(2,2,4,4-tetramethyl-piperidinil-1-oxyl)]-carboxamide-1-R (whereR = methyl or R = dodecyl)-pyridinium iodide free radicals)) on silica gel with anhydrous (!) methanol - water 24:1 in a saturated N-chamber. Coupling of HPTLC with EPR involves removing each spot together with the stationary phase from the plate, deposition on the quartz capillary and analysis.
J. Agric. Food Chem. 50, 1200-1206 (2002). TLC of 1-methylpyridinium on silica gel with ethyl acetate - methylethylketone - formic acid - water 5:3:2:1. Detection under UV.
J. Liq. Chromatogr. Relat. Technol. 33, 922-935 (2010). TLC and HPTLC of 22 different pyridinium aldoximes on silica gel with water - acetonitrile - acetic acid 8:1:1, water - acetone - acetic acid 8:1:1, and acetone - 50 mM aqueous sodium acetate 1:4 using unsaturated and saturated vapor phase as well as OPLC. Detection under UV 254 nm.
J. Liq. Chromatogr. & Relat. Technol. 30, 557-574 (2007). TLC of trigonelline (3-carboxy-1-methylpyridinium hydrochloride) and degradation products on silica gel with n-propanol - methanol - water 4:1:4 in a twin-trough chamber. Quantitative determination by absorbance measurement at 269 nm.
J. Liq. Chromatogr. Relat. Technol. 33, 1038-1046 (2010). TLC of nicotinic acid and methyl, ethyl, isopropyl, butyl, hexyl, and benzyl nicotinate (heated for 1 to 7 h at 120 °C) on silica gel pre-washed with methanol using methanol - benzene (for nicotinic acid) and acetone - hexane 2:3 for nicotinic acid esters. Quantitative determination by densitometric absorbance measurement at the respective absorption maximums (263 nm for nicotinic acid, 220-222 nm for nicotinic acid esters). The hRf of nicotinic acid was 44, and of methyl, ethyl, isopropyl, butyl, hexyl, and benzyl nicotinate 48, 46, 51, 54, 56, and 44, respectively.)
