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. The saved items can be printed to PDF using the print function of your web browser.

      The signatures of energy-transducing organic molecules in meteorites
      S. GHOSAL (Natreon-Inc., CL-18A, Sector II, Salt Lake City, Kolkata 700091, India)

      Sci. Cult. 74 (1-2), 22-30 (2008). Bio-organic molecules such as oxygenated dibenzo-a-pyrones, their aminoacyl conjugates, and polyprenylbenzo-quinones have earlier been reported as transducers of energy in animals and human cells and were now found in four samples of meteorites. HPTLC on silica gel 60 with 1) n-butanol - acetone - acetic acid - water 7724 for amino acids, followed by detection with ninhydrine reagent and densitometric evaluation at 610 nm; 2) n-butanol - acetic acid - water 312 for sugars, followed by detection with p-anisidine reagent and densitometric evaluation at 380 nm; and 3) chloroform - methanol 91 for dibenzopyrones, followed by densitometric evaluation at 240 nm and 360 nm.

      The signatures of energy-transducing organic molecules in meteorites
      S. GHOSAL (Natreon-Inc. CL-18A, Sector II, Salt lake City, Kolkata 700091, India, vishnu20024@rediffmail.com)

      Science & Culture Jan.-Feb., 22-30 (2008). Isolation and identification of some unique chemical compounds is reported using chemical, chromatographic and spectroscopic methods such as GC-MS, HPTLC and HPLC. The presence of bio-organic molecules such as oxygenated dibenzo-a-pyrones (DBPs), their amino acyl conjugates (DCPs) and polyphenyl benzoquinones (PBQs) was observed in all the four samples of meteorites. HPTLC on silica gel with 1) n-butanol - acetone - acetic acid - water 7724 for amino acids, detection with ninhydrine reagent and absorbance measurement at 610 nm; 2) n-butanol - acetic acid - water 312 for sugars, detection with p-anisidine reagent and absorbance measurement at 380 nm; 3) chloroform - methanol 91 for DBPs and absorbance measurement at 240 nm and 360 nm.

      Effect-directed analysis of environmental samples
      G. REIFFERSCHEID, Denise SPIRA*, S. BUCHINGER* (*Federal Institute of Hydrology, Department Bio-Chemistry & Ecotoxicology (G3), Am Mainzer Tor 1, 56068 Koblenz, Germany, spira@bafg.de, buchinger@bafg.de)

      CBS 112, 5-7 (2014). HPTLC-AMD of sediment samples and standards 17?-ethinylestradiole, 17ß-estradiole, estrone and bisphenol A on silica gel with a two step gradient, first step with methanol to 20 mm, second step with ethyl acetate - n-hexane 11 to 80 mm. Detection with the p-YES-bioassay by dipping in yeast cell suspension (the cell number of the genetically modified yeast strain (Saccharomyces cerevisiae BJ3505) was determined by photometry and diluted to 150 ± 50 Formazin Attenuation Units) followed by incubation for 3 h at 30 °C in a saturated steam atmosphere. Then the enzyme substrate solution (0.5 mg/mL 4-methylumbelliferyl-ß-D-galactopyranoside solution) was sprayed on the TLC plate followed by a second incubation for 30 min at 37 °C. Detection under UV 254 nm and quantitative fluorescence measurement at UV 320/>400 nm. Two blue fluorescent zones with estrogenic activity were detected at hRF 65 and 80.

      Application of principal-components analysis to the choice of optimum solvent system for the separation of polycyclic aromatic hydrocarbons by TLC
      A. BOTA, C. SARBU, C. MARUTOIU*, V. COMAN (*Inst. of Chem. Raluca Ripan, str. Fintinele nr. 30, R-3400 Cluj-Napoca, Romania)

      J. Planar Chromatogr. 10, 358-361 (1997). TLC of seven PAHs (7-, 8-hydroxy-, trans-7,8-, trans-9,10-dihydroxybenzo(a)pyrene, benzo(a)pyrene, 1,2,5,6-dibenzanthracene, chrysene) on cellulose acetate with various solvent systems and application of principal-components analysis (PCA) to the experimental results in order to find the optimum solvent system for the separation of the hydrocarbons of interest.
