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. China Assoc. Inst. Anal. 6, 19-22 (1987) (Fenxi Ceshi Tongbao). TLC on silica with chloroform - methanol - acetic acid - water 80:10:8:2. Detection by exposing to iodine vapour. Quantification by densitometry at 520 nm.
Analyst 112, 1663-1665 (1987). TLC on silica with chloroform - methanol 85:15. Detection under UV 366 nm. Quantification by densitometry.
J. Planar Chromatogr. 2, 65-70 (1989). For qualitative analysis monodansyl cadaverine (MDC) was employed without further purification. Column-chromatographic purification is recommended for the quantification of short chain carboxylic acids. For in situ derivatization the carboxylic acid sample solutions were applied to the HPTLC plates as bands with a maximum length of 10 mm. These were then „overlayed“ with MDC solution containing N,N’-dicyclohexylcarbodiimide to activate the acids. Short-chain carboxylic acids were separated on normal silicagel phases with toluene - ethyl acetate - ammonia mixtures as mobile phase. Stepwise and gradient developments allow the baseline separation. Long-chain carboxylic acids are better separated on RP-18 phases with acetonitrile-tetrahydrofuran mixtures and methanol as mobile phase.
Chromatographia 32, 307-316 (1991). HPTLC on NH2-bonded silica with different solvent systems. Detection by heating at 150 °C. Quantification by densitometry in fluorescence mode at 366 nm. The detection limits in any case, below the physiological range.
Chromatographia 35, 627-630 (1993). TLC separation of free fatty acids into two fractions, a more mobile group of saturated and monounsaturated fatty acids and a less mobile group containing polyunsaturated fatty acids, on silica with hexane - acetic acid - water 50:2:1. Detection by exposure to iodine vapor, and under UV 254 nm. Determination of polyunsaturated fatty acids by HPLC.

Detection by spraying with 10% sulfuric acid in ethanol and heating at 105 °C for 5 min. Quantification by fluorodensitometry at 365 nm.
J. Chin. Trad. Med. (Zhongguo Zhongyao Zazhi) 20, 216-217 (1995). TLC on silica with chloroform - methanol - formic acid 40:1:1. Detection by spraying with 10 % sulfuric acid and heating at 90 °C for 10 min. Quantification by densitometry at 510 nm.
Acta Chromatographica 8, 5-12 (1998). HPTLC of EHMC on RP-18 with preadsorbent spotting area (prewashed with dichloromethane - methanol 1:1 and equilibrated with the mobile phase for 15 min) with methanol - tetrahydrofuran - deionized water 50:35:15. Detection under UV 254 nm. Quantitation by densitometry at 302 nm. Validation of accuracy, determination of precision. The relative standard deviation was 6.80% with a range 1.40 - 9.87% (n = 4). Average recoveries were 101.7 and 104.0%.
