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.
Vergleich UV/Vis und IR. (Spectral detection in thin layer chromatography - Comparison UV/Vis and IR). Dünnschicht-Chromatographie InCom Sonderband 1996, 1-13. Description of spectral UV/Vis detection and direct HPTLC-FTIR-in situ measurement, in particular for investigation of mixtures where spectral detection can be used directly for quantification. Discussion of detection limits and possibilities for identification. Substances chromatographed: 7,7'-diethylamino-4-methylcoumarin, perazine, caffeine, nitrazepam.
J. Chin. Trad. Med. (Zhongguo Zhongyao Zazhi) 21, 81-84 (1996). TLC on silica with 1) petrol ether - ether 15:1, 2) petrol ether - ethyl acetate 4:1. Detection by spraying with 10 % sulfuric acid in ethanol and heating at 105 °C for 10 min. Comparison of the chromatograms.
J. Planar Chromatogr. 9, 390-394 (1996). HPTLC of isoniazide and pyridoxine hydrochloride on silica with acetone - carbon tetrachloride - 6.5 M NH3 21:7:2. Densitometry at 275 nm. Precision within-day and between-day 0.88-1.21% and 0.45-1.02%, respectively. Simple, precise, and rapid HPTLC procedure.

Quantification of ligustilide by densitometry at 290 nm. Validation of the method by investigation of its precision (RSD 2.4 % n=5 within plate and 3.0 % n=5 plate-to-plate), reproducibility (2.5 % n=6 within three hours), and recovery (96.7 %, RSD 2.2 % n=5).
CBS 87, 6-7 (2001). HPTLC on silica gel with chloroform - methanol - water 6:4:1. Detection by spraying with 10 % ethanolic sulfuric acid solution, followed by heating at 120 °C. Quantitative determination by absorbance measurement at 450 nm.
CBS 91, 12-13 (2003). HPTLC of flavonoids with tetrahydrofuran - toluene - formic acid - water 16:8:2:1, diterpenes with toluene - ethyl acetate 9:2, and iridoids with ethyl acetate - methanol - water 77:15:8 (with chamber saturation), in horizontal developing chamber over 52 mm. Detection of flavonoids by dipping warm plate in natural products reagent (0.5 % in ethyl acetate) followed by dipping in PEG 400 solution (5 % in dichloromethane), of diterpenes by dipping in 10 % methanolic sulfuric acid followed by heating at 105 °C, and iridoids by dipping in 4-dimethylaminobenzaldehyde reagent (1 % in 1 N methanolic HCl). Visual evaluation at 366 nm (flavonoids), white light (diterpenes), and white light with sharp cut filter 560 nm (iridoids). Stability of extracts was investigated under drastic stress conditions (acid, base, light, heat, humidity).
