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.
Biochemical Systematics and Ecology 17, 455-457 (1989). TLC on polyamide with benzene - MEK - methanol 30:13:7. Visualization under UV before and after spraying with diphenyl borate-ethanol-amine complex in 50% methanol.
Biochemical Systematics and Ecology 17, 509-517 (1989). TLC of sesquiterpene lactones on silica with dichloromethane - acetone - ethyl acetate 5:4:1. Visualization by spraying with Ehrlich’s reagent.
J. Planar Chromatogr. 2, 77-79 (1989). HPTLC of urine extracts on silica with ethyl acetate - methanol - NH3 25% 85:10:5. Doping control by post-chromatographic derivatization. Esidrex and similar drugs as well as their metabolites are converted into azo dyes. Drug monitoring by densitometry. Determination limit of the method described is 0.2 mg/L and the sensitivity limit is 0.1 mg/L. The procedure allows the analysis of a large number of samples in a short period of time with minimal operating costs.
Chromatographia 29, 44-50 (1990). HPTLC of azidothymidine and its degradation product thymine on silica with a) methanol - chloroform 5:95, 7:93, 10:90, 15:85, b) butanol - heptane - acetone - NH3 26% 4:3:3:1. Quantification by densitometry at 268 nm. The calibration curve for HPTLC was linear over the range of 25 - 100 ng thymine/spot. Also, reversed-phase HPLC.
J. Planar Chromatogr. 3, 55-60 (1990). A strategy for the optimization of chromatographic conditions in TLC-separation of the lipid classes in lecithins of egg yolk, rapeseed, and soybean origin was developed. This approach utilizes factorial design in sequential blocks to screen the variables (in this work, 15 in number), principal component analysis to map the experimental domain, and partial least squares regression for the final optimization. Chromatography on silica, postchromatographic derivatization with 3% cupric acetate in 8% o-phosphoric acid heated at 180°C for 8 min, substances appear as brownish spots. Scanning by absorbance at 350 nm.
Biochemical Systematics and Ecology 18, 307-316 (1990). TLC of canthaxanthin, native xanthophylls, peridinin and peridininol on silica – CaCO3 1:1 with petrol ether – acetone – isopropanol 69,5:25:4:1,5, or on silica – Ca(OH)2– MgO – CaSO4 10:4:3:1 with petrol ether – acetone – benzene – isopropanol 69.5:25:2:1.5.
Don Hara.) (Chinese). Chinese J. Pharm. Anal. (Yaowu Fenxi Zazhi) 10, 227-230 (1990). TLC on silica with toluene – ether – methanol – formic acid 1:2:0.2:0.1. Quantification by densitometry at 280 nm. The calibration curve was linear over a range of 0.13 – 176 µg/spot. Recovery 98%.
Chinese J. Pharm. Anal. (Yaowu Fenxi Zazhi) 10, 105-107 (1990). TLC on silica with acetone first, and then with ethyl acetate – isopropanol – water 10:7:3. Detection by spraying separately with Vaskovsky’s reagent, ninhydrin, and Dragendorff’s reagent for different components. Quantification of total phospholipids by colorimetry after elution, or by comparison of spot areas.
