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

Phytochemistry. 119, 51-61 (2015). HPTLC of cochloxanthine (1) and dihydrocochloxanthine (2) in Cochlospermum species on silica gel with acetone - hexane 1:1. Detection by spraying with anisaldehyde reagent, followed by heating at 110 °C for 5-10 min. Identification under UV light at 254 nm and 366 nm. The hRF values for (1) and (2) were 53 and 49, respectively.
J. of Medicinal Chemistry 31, 1575-1579 (1988). TLC of 2-[(2,2-diethoxyethyl)thio]acetamide and 4-[2,3, 5-tri-O-benzoyl-ß-D-ribofuranosyl]-1,4-thiazin-3-one on silica with hexane - ethyl acetate 90:1 and hexane - ethyl acetate 85:15. Visualization under UV or by spraying with ethanol - p-anisaldehyde - sulfuric acid 100:1:1.
J. Chromatogr. 612, 57-61 (1993). TLC of nucleotide glycation reaction products on silica with propanol - methanol - NH3 - water 3:1:1:1. Detection under UV 254 nm. Also HPLC.
J. Planar Chromatogr. 10, 416-419 (1997). Complete validation of an HPTLC method for the quantitative determination of caffeine in Coca-Cola has been performed according to ICH guidelines, taking into consideration the special features of the method. The validation parameters were: selectivity, stability of the analyte, linearity, precision, (repeatability and intermediate precision), and robustness. Quantification with a slit-scanning densitometer and with an image-analyzing system. The same plates were used in both validation procedures to reveal possible differences between the different modes of quantification. The results obtained show no difference in validation parameters - because all the results are within the range of criteria recommended for TLC validation. Both systems can be used for quantitative evaluation of TLC plates.
J. Chromatogr. 612, 295-301 (1993). TLC of 32P-postlabeled DNA adducts on polyethyleneimine-cellulose with different mobile phases. Detection by intensifying screen-enhanced autoradiography. Quantification by Cerenkov counting with adducts expressed in counts per minute. Discussion of the separation, resolution, recovery, retention of background noise, and developing time.
Acta Chimica 113, 443-458 (1983). TLC of 4-0-acetyl-2,5-anhydro-6-azido-1-(4,5-dicarbo-methoxyl-2,3-triazolyl)-1,6-dideoxy-3-0-methyl-sulfony-L-iditol; 3-0-acetyl-2,5-anhydro-1,6 bis (4-carboxanido-5-amino-1,2,3-triazolyl)-1,6-di-deoxy-L-iditol on silica with a) CCI4 ethyl acetate 1:2 or 1:3, b) dichloroethane - ethyl acetate 1:1 or 5:1, c) ethyl acetate. Detection by spraying with 0.1 M KMnO4 -1 M sulfuric acid 1:1 and heating at 105 °C.
Chinese J. Herb Med. (Zhongcaoyao) 25 (3), (1994). TLC of allantoin on silica with methanol - acetone - formic acid - water 40:2:1:6. Detection by spraying with p-dimethylaminobenzaldehyde in ethanol. Densitometry by absorbance at 445 nm.
CBS 113, 9 (2014). HPTLC of caffeine in energy drinks (applied neatly without sample preparation) on silica gel MS-grade with 2-propanol – n-heptane – water 7:3:1. Detection under UV 254 nm and by dipping into anisaldehyde reagent. Quantitative evaluation by absorbance measurement at 273 nm. The hRf of caffeine was 55. For confirmation of results, zones were eluted with the TLC-MS Interface (acetonitrile – water 19:1 with 0.1 % formic acid, flow rate 0.1 mL/min) and directly transferred to a mass spectrometer and measured in ESI(+) full scan mode (m/z 100 – 500).
