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. 2, 397-398 (1989). TLC separation of 5 alkaloids (atropine, berberine, brucine, ephedrine, quinine) on either cadmium sulfate, zinc sulfate or nickel chloride containing silica gel with butanol - formic acid 1:1 as eluent. Location of spots by iodine chamber.
Chinese J. Pharm. Anal. (Yaowu Fenxi Zazhi) 10, 258-260 (1990). TLC of strychnine (1), brucine (II) and ephedrine (III) on silica with chloroform – methanol – NH3 4:7:2. Detection under UV for I and II, and by spraying with ninhydrin reagent and heating at 110°C for III. Quantification by densitometry at 254 nm for I and II, and 510 nm for III. Comparison of the optimization methods for solvent system – orthogonal design, numerical analysis, simplex and uniform design.
J. Planar Chromatogr. 3, 193-195 (1990). TLC of alkaloids (lysergol, ergometrine, agroclavine, ergotamine, ergocristine, ergotaminine, ergocristinine) on silica with water - ethanol - ether 1:7:12 or acetonitrile - ethanol - toluene 17:2:1 was unsatisfactory with both normal HPTLC or OPLC; satisfying results were obtained with circular U-RPC. Quantification by densitometry (absorbance at 300 nm).

TLC of eight isoquinoline alkaloids on silica with toluene – methanol – diethylamine 60:5:2 saturated with formamide. Detection by exposing to iodine vapors and heating at 180 °C for 20 min. Quantification by fluoro densitometry at 350 nm/>400 nm.
J. Chinese Herb Med. (Zhongcaoyao) 23, 579-580 (1992). Preparative column chromatography using alumina. Monitoring of fractions by TLC on silica and alumina with chloroform - acetone 4:1 and 2:1. Detection by spraying with potassium iodobismuthate.
Chinese J. Pharm. Anal. 13, 236-237 (1993). TLC of morphine on silica with ethyl acetate - methanol NH3 85:10:5. Detection under UV 254 nm. Quantification by densitometry at 280 nm.
J. Planar Chromatogr. 7, 221-228 (1994). One and two-dimensional HPTLC of benzophenanthridine alkaloids on silica with benzene - methanol 6:1 and with chloroform - benzene - methanol - formamide 80:100:20:1. Visualization under UV. Quantification by coupling TLC-FAB. The combination of mass spectrometric detection with a chromatographic separation method provides analytical data of equal utility for characterization of this mixture as does capillary electrophoresis, but the higher loadings of material on the TLC plate enable easier identification of the mixture components. Despite the perceived lower reproducibility for TLC, it is shown that reproducibility in Rf and mass spectral data is excellent.
Chinese J. Pharm. Anal. (Yaowu Fenxi Zazhi) 15 (3), 46-47 (1995). TLC of alkaloids on silica with benzene - acetone - methanol - NH3 160:80:12:5. Detection by spraying with iodoplatinate reagent. Investigation of the detection limits.
