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.

      A new method of derivatization in planar chromatography
      E. POSTAIRE*, C. SARBACH, P. DELVORDRE, C. REGNAULT, (*Anal. Development Lab., Central Hospitals’ Pharmacy, 7 Rue de Fer à Moulin, 75005 Paris, France)

      J. Planar Chromatogr. 3, 247-250 (1990). TLC of tryptophan on cellulose with 1-butanol - acetic acid - water 4:1:5. Detection by overpressure derivatization (OPD), which is carried out by pressing an absorbent polymeric pad (prewetted with derivatization reagent) on the TLC plate. Relative standard deviations obtained showed that OPD was more reproducible than spraying. Quantification by densitometry (absorbance at 420 and 288 nm after derivatization).

      J. Planar Chromatogr. 3, 149-152 (1990). HPTLC of vitamin B1 on silica with methanol - NH3 (25%) - acetic acid - chloroform 18:2:1:1. Postchromatographic derivatization with tert-butyl hypochlorite or potassium hexacyanoferrate(III) - sodium hydroxide. After fluorescence enhancement by dipping the plates into a mixture of chloroform - liquid paraffin - triethanolamine 6:1:1. Quantification by in situ fluorometry. Detection limit: 500 pg vitamin B1 per chromatogram zone.

      Quantitative HPTLC determination of cyproterone acetate and ethynyl estradiol in pharmaceuticals
      J. NOVAKOVIC, I. NEMCOVA*, M. VASATOVA, (*Fac. of Natural Sci., Dept. of Anal. Chem., Charles Univ., Albertov 2030, 12840 Prague 2, Czechoslovakia)

      J. Planar Chromatogr. 3, 407-409 (1990). HPTLC of cyproterone acetate and ethynyl estradiol on silica with cyclohexane - ethyl acetate 6:4 as mobile phase and 17ß-estradiol as internal standard. quantification by densitometry (absorbance at 284 nm). Detection limit for cyproterone acetate was 5 ng, for ethynyl estradiol 30 ng. The relationship between the spot concentration and the cyproterone acetate 17ß-estradiol area ration was linear over a range of 5 to 120 ng; for ethynyl estradiol the linear range was 120 to 1200 ng. The proposed assay is suitable for routine drug control.
