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. 19, 238-240 (2006). HPTLC of plant extracts, using pellitorine and dihydropiperlongumine as markers, on silica gel in a twin-trough chamber saturated with the mobile phase hexane - ethyl acetate 3:1. Quantitation by densitometry in absorbance/reflectance mode at 260 nm.
J. Chromatogr. 264, 336-338 (1983). For forensic purposes, this TLC method for the clean-up of urinary extracts is an important step in isolating the metabolite. The elution for the TLC spot corresponding in Rf and Fast Blue B stain color to delta 9-THC-COOH provided an extract for gas chromatographic (GC)-mass-spectrometric (MS) determination. TLC of 11-nor- delta 9-tetrahydrocannabinol-9-carboxylic acid on silica with chloroform - methanol - NH3 70:30:2. Detection with Fast Blue B.
Phytochem. Analysis 17, 409-413 (2006). HPTLC of gymnemic acid as of gymnemagenin from callus cultures of Gymnema sylvestre on silica gel with chloroform – methanol 4:1. Quantitative determination by absorbance measurement at 205 nm. Linearity of determination of gymnemagenin is between 2 and 10 µg and its average percentage recovery from leave callus extracts is 98.6 - 99.2 %.
(Problems in the separation of isomeric 2-aminobenzo phenones as intermediates in the preparation of anellated 1,4-benzodiazepines.) Fresenius Z. Anal. Chem. 318, 241-242 (1984). TLC of isomeric 2-amino benzo phenones on silica with cyclohexane - ethyl acetate 5:5. Detection by UV 254 nm.
V. Thin-Layer Chromatography on silica gel vs. alumina of 3,4-disubstituted isochroman-1-ones including spiro analogues. J. Liq. Chromatogr. Relat. Technol. 28, 2539-2550 (2005). TLC of 8 substituted isochromanones and 4 spiro analogues on silica gel and alumina with 10 computer selected mobile phases. The procedure takes into account the adsorption properties of the mobile phase (parameter epsilon and tuning parameters m and P’), stationary phase and sample structure expressed by the relevant group. Silica gel was more effective and did not cause decomposition in contrast to the alumina phase.
J. Microchem. 31, 298-303 (1985). TLC determination of 5-aza-2'-deoxycytidine and degradation products on cellulose with butanol - acetic acid - water 10:1:3. Detection by UV 254 nm and with FCNP reagent (10 % aq. NaOH solution, 10 % aq. potassium ferricyanide solution, 10 % aq. sodium nitroprusside solution, water 1:1:1:3 - one part of this solution is mixed with acetone 1:1 before spraying.
J. Liq. Chromatogr. Relat. Technol. 29, 877-887 (2006). HPTLC of curcuminoids (curcumin, demethoxycurcumin, and bis-demethoxycurcumin) on spherical silica gel with chloroform - methanol 49:1 with chamber saturation. Densitometry at 366 nm in adsorption-reflection mode.
J. Planar Chromatogr. 3, 20-23 (1990). HPTLC separation and identification of open intermediates and final products in synthesis of 6 and 7-substituated 3-methylquinoxalin-2(1H)-ones on silica gel with benzene – methanol 9:1. Visualization by UV 254 and 366 nm. The diaza-isomers appeared as dark blue spots on green background at 254 nm, and had light blue fluorescence at 366 nm on blue background. Open products did not fluoresce at 366 nm. Concentrations of samples were about 10-4 to 10-6 M for the intermediates.
