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. 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.
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).
Biologically active compounds from the marine sponge Geodia baretti. J. of Natural Products 51, 1277-1280 (1988). TLC of nucleosides on silica with ethanol - NH3 (25%) 8:2 or chloroform - methanol 1:1. Visualization under UV 254 nm and 366 nm; also by spraying with ninhydrin or vanillin-sulfuric acid.
J. Chromatogr. 612, 277-285 (1993). Two-dimensional TLC of deoxy-deazapurines (deaza-dNMPS) on polyethyleneimine-cellulose. Detection by 32P-labeled cold DNA, and scintillation and laser densitometry.
J. Chromatogr. B 706, 149-156 (1998). TLC of cyanocobalamin derivatives on silica gel with 2-butanol - acetonitrile - water 143:1:56. Identification by using Rf values in comparison to retention times in RP-HPLC.
J. Liq. Chromatogr. Relat. Technol. 40, 50-57 (2017). HPTLC of six nucleobases, guanosine (1), guanine (2), cytosine (3), adenine (4), uracil (5), and thymine (6) in sea buckthorn leaves on silica gel with dichloromethane – methanol – formic acid 160:45:16. Detection at UV 254 nm. The hRF values for (1-6) were 17, 23, 32, 38, 64 and 73, respectively. The bands were eluted using a TLC–MS interface and subjected to electrospray ionization-mass spectrometry (ESI-MS)._x000D_
(Chinese): Chinese J. Pharm. Anal. (Yaowu Fenxi Zazhi) 8, 316-317 (1988). TLC of propylthiouracil on silica with 1) chloroform - isopropanol - acetic acid 50:6:1, 2) cyclohexane - ethyl acetate 2:8, 3) benzene - ethyl acetate 1:1, 4) hexane - acetone - ethanol 60:20:2. Detection under UV 254 nm and by exposing to iodine vapor.
