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

J. Chinese Trad. Patent Med. (Zhongchengyao) 22 (7), 483-485 (2000). TLC on silica gel with 1) petroleum ether (60-90°C) - ethyl acetate - methanol 16:3:1, 2) ethyl acetate - ethanol - water 18:2:1, 3) chloroform - methanol - water 30:10:1. Detection 1) by spraying with vanillin - ethanol - sulfuric acid 1:90:10 and heating at 100° for 5 min, 2) by spraying with p-dimethylaminobenzaldehyde - ethanol - sulfuric acid 1:90:10 and heating at 105°C for 5 min. Comparison of the fingerprints, and of the UV spectra.
Proc. Intern. Symp. on Planar Separations, Planar Chromatography 2001, pp. 363-371. HPTLC of selected flavan-3-ols [(-)-epicatechin-3-gallate, (+)-catechin, (-)-epicatechin and (-)-epigallocatechin] on cellulose with aqueous solutions of sodium chloride (10 mg/ml) containing different concentrations of b-cyclodextrin. Acetone and 1-butanol were used as organic modifiers. An unsaturated horizontal developing chamber was used for the separations. Detection under UV 366nm. After that the spots were visualized by dipping the plates in anisaldehyde-sulfuric acid reagent. A Video Documentation System was used for recording and analyzing the images of the developed TLC plates.

by thin-layer chromatography.) (Chinese). J. Chinese Trad. & Herb. Drugs (Zhongcaoyao) 33 (6), 513-515 (2002). TLC on silica gel with a solvent system composed of benzene, acetone and methanol. Optimization by systematically adjusting the proportions of the solvent components, the system benzene - acetone - methanol 9:3:2 was the best.
J. Planar Chromatogr. 15, 433-436 (2002). Improvement of separation TLC of (+)-catechin and (-)-epicatechin on cellulose with 1-butanol - water - acetic acid 4:2:1, developed in horizontal chambers (tank and sandwich configuration), with and without preconditioning. Prewashing of the plates, preconditioning, and the type of developing chamber had a large effect on the chromatographic results. Without prewashing of the TLC plate unsatisfactory or misleading results were obtained. Anisaldehyde-sulfuric acid dipping reagent proved to be more selective than vanillin - phosphoric acid as detection reagent for flavan-3-ols; the latter was, however, more sensitive.
