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. Planar Chromatogr. 17, 369-371 (2004). TLC of 9-phenylxanthene derivatives (fluorescein, erythrosine, eosin, rhodamine B, and their allyloxy-derivatives) on silica gel with benzene - methanol 5:1, toluene - ethanol 7:1, acetontrile - water 7:1, toluene - ethyl acetate - methanol 1:5:2. Detection under UV light at 254 nm or with iodine vapor. Quantitation by densitometric scanning.
J. AOAC Int. 91, 1387-1396 (2008). HPTLC on silica gel with chloroform - methanol 9:1 in the first direction for curcumin, demethoxycurcumin, bis(demethoxy)curcumin, and the synthetic dye metanil yellow, and with toluene - hexane - acetic acid 50:50:1 for sudan I and sudan IV in the second direction. Quantitative determination by absorbance measurement at 420 nm for curcumin and metanil yellow, at 491 nm for sudan I, and at 520 nm for sudan IV.
J. Planar Chromatogr. 28, 6-11 (2015). TLC of nine reactive dyes, seventeen fluorescent brighteners (nine of them are triazine-stilbene derivatives and eight of them are 2-aminodimethylterephthalate derivatives) and their intermediates (twenty four in number), all of them containing 4-amino-2,2,6,6-tetramethylpiperidine stabilizer fragment, on silica gel with n-propanol - ammonia - ethyl acetate 3:2:4 or heptane - propanol 1:1. Detection at UV 254 nm.
J. Planar Chromatogr. 30, 113-120 (2017). HPTLC of brilliant green, green fat, green S, iochrome black, oil red, natural red, rhodamine, patent blue, brilliant blue, brilliant black, azorubin, ponceau 4R, allura red, tartrazine, 1-aminoanthraquinone, (4-[2-pirydylazo]resorcinol), quinoline yellow, thymol blue and curcumin on RP-18 by isocratic elution with different concentrations of methanol in water (0-100 % v/v) with addition of 100 mM trifluoroacetic acid (TFA); and by gradient elution using a 2012 proposed horizontal developing chamber for stepwise gradient elution in reversed-phase mode, with different concentrations of methanol and buffer (pH=3.0, 3 mM citric acid and 1.5 mM disodium hydrogen phosphate in deionized water). When the citrate buffer was replaced by TFA the front of the mobile phase was more uniform and the phenomenon of flow of the mobile phase to the surface of the adsorbent layer was not observed; therefore, the substance zone was well shaped. The best gradient separation was obtained with a 4-step convex gradient: the concentrations of methanol in subsequent fractions of the mobile phase were 40, 60, 70, and 80 % (v/v) and the migration distances of the fractions were 10, 10, 20 and 30 mm, respectively. The total development distance was 70 mm. The results showed high repeatability within the same plate and between studies. The highest values of precision (%RSD >2 %) were obtained for the most strongly retained substances (oil red, dye No. 8, and fat green, dye No. 2).
The effect of support and the organic phase in the eluent. Chromatographia 25, 908-914 (1988). Determination of the lipophilicity of some photosynthetic pigments by reversed-phase TLC on silica, alumina, cellulose, polyamide and diatomaceous earth with water - acetone and water - ethanol. Investigation of the effect of support and the organic phase in the eluent.
