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.
Tetracyclinhydrochloric (Oxytetracyclinhydrochorid), Chlortetracyclinhydrochlorid, Demeclocyclinhydrochlorid, Doxycyclinhydrochlorid, Minocyclinhydrochlorid. (German). Deutsche Apotheker Zeitung 129, 1841-1842 (1989). TLC of tetracycline on cellulose with 5g MgCl2•6 H2O and 0.3 g Na2EDTA•2 H2O in 100 mL water + 2 mL acetic acid. Detection by spraying with NH3 and under UV 365 nm. TLC of tetracycline and oxytetracycline on cellulose with isopropanol - acetone - water 75:15:15. Detection under UV 365 nm.
Application of methylation with diazomethane for the detection of lac color. J.A.O.A.C. 72, 48-51 (1989). TLC of reaction products of natural red colors methylated with ethereal diazomethane on silica with chloroform - methanol - water 90:10:1 resp. on cellulose with methanol - ethanol - 10% acetic acid 6:1:3.
Acta Biologica Hungarica 39, 59-74 (1988). TLC of cannbichromene and tetrahydrocannabinoid on silica with 2% fast blue salt in 70% ethanol (OPTLC method).
HPTLC of flavonoid glycosides on silica with ethyl acetate - formic acid - water 6:1:1. Detection by spraying with 1% methanolic solution of ethanolamine diphenylborate and 5% ethanolic solution of polyethylene glycol 400, and under UV 360 nm. Quantification by densitometry at 445 nm.
J. Planar Chromatogr. 2, 92-94 (1989). TLC of 9 amino acids on silica with pH values of 3.0, 4.5, 6.0, 7.5 and 9.0 and impregnated with 5% paraffin oil in hexane; detection with ninhydrin. Mostly, retention decreases with increasing surface pH value. Dibasic amino acids (Arg, Lys, Orn) increase with increasing pH of the silica surface.
J. Chromatogr. 469, 390-395 (1989). TLC of some common natural products on silica with 7 different solvent systems. Detection by densitometry. Identification by comparison of their characteristic Rf values, absorbance ration, etc.
Phytochemical Analysis 1, 44-47 (1990). HPTLC of 17 different flavone aglycones with unsubstituted B rings on silica with chloroform or petrol ether (40-60°C) – ethyl acetate 1:1. Detection under UV 360 and 254 nm. Correlations between structural features, Rf values and elution order have been established. In addition, characteristic fluorescent colors under UV 360 nm depend only on the substitution pattern on the A ring and are useful for identification purposes.
Biochemical Systematics and Ecology 18, 251-252 (1990). TLC of a-allo-cryptopine and dictamnine (alkaloids), limonin, limonexic acid and calodendrolide (limonids) on silica with chloroform – methanol 3:1.
