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.

      Analysis of lycopene in nutritional supplements by silica gel high-performance thin-layer chromatography with visible-mode densitometry
      J.D. VASTA*, J. SHERMA (*Lafayette College, Department of Chemistry, Easton PA 18042-1782, USA)

      Acta Chromatographica 20(4), 673-683 (2008). Presentation of a quantitative method for the analysis of lycopene in nutritional supplements consumed to reduce the risk of prostate cancer and other forms of cancer and cardiovascular disease. HPTLC on silica gel with petroleum ether – dichloromethane 9:1. Quantification by densitometry at 416 nm. Four products containing 300 µg, 3 mg, 5 mg, or 10 mg lycopene plus other ingredients were quantified using a lycopene standard: the measured amounts ranged from 77.7 to 98.1 % of the stated label values. The accuracy by spiked blank analysis was within 1.90 % of theoretical values for the 3 mg softgels and 1.10 % of theoretical values for the 10 mg softgels. The precision of replicate analyses showed a RSD of 1.44 % for the 10 mg softgels and 2.39 % RSD for the spiked blank for the 3 mg softgels. The results obtained for Lycopene standards available from two other companies showed 55.6, 57.6, and 20.0 % of the minimum amount expected from the stated label values.

      Phosphorescence quenching of dyes adsorbed to silica thin-layer chromatography plates
      B.H. HAN, I. MANNERS, M.A. WINNIK* (*Department of Chemistry, University of Toronto, 80 St. George Street, Toronto, ON M5S 3H6, Canada)

      Anal. Chem. 77 (24), 8075–8085 (2006). Description of photoluminescence quenching experiments by oxygen for a series of transition metal dyes adsorbed on silica gel. The quenching kinetics showed differences regarding the behavior of the same dyes adsorbed to the well-defined surfaces of SBA-15 mesoporous silica particles and adsorbed to a thin layer-by-layer polymer film. Pore size and pore size distribution are larger for TLC silica than for mesoporous silica. On TLC silica the dye photoluminescence decay profiles show smaller deviations from an exponential form, and larger differences between the intensity and lifetime Stern-Volmer plots. Dyes adsorbed to TLC silica gel are three times more sensitive to quenching by oxygen.
