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.

      Thin-layer chromatographic determination of the pKa values of organic acids and bases
      B. Tyman-Szram, R. Musiol, M. Sajewicz, J. Polanski* (*Department of Organic Chemistry, Institute of Chemistry, University of Silesia, 40-006 Katowice, Poland)

      J. Planar Chromatogr. 18, 323-325 (2005). TLC of salicylic and benzoic acid on silica gel and of phenol, paracetamol, quinoline, 8-hydroxyquinoline, 4-bromoaniline, 2-chloroaniline, salicylic acid and benzoic acid on silica gel modified with DC 200 silicone oil with methanol - buffer in different volume ratios. TLC can be a valuable method for the determination of the pKa values of organic acids and bases. It is a simple and inexpensive alternative to the HPLC procedure.

      Curcumin, a major component of food spice turmeric (Curcuma longa) inhibits aggregation and alters eicosanoid metabolism in human blood platelets
      K.C. SRIVASTAVA, A. BORDIA, S.K. VERMA, (Dept. of Environmental Med., Inst. of Community Health, Odense, Denmark)

      Prostaglandins Leukotr Essent Fatty Acids 52, 223-227 (1995). TLC of hydroxy derivatives of arachidonic acid (12-hydroxyheptadecatrienoic acid and 12-hydroxyeicosatetraenoic acid), thromboxane B2, prostaglandins and phospholipids on silica with the upper organic phase of ethyl acetate - isooctane - acetic acid - water 11:5:2:10 or hexane - ether - acetic acid 80:30:1. Detection by exposure to iodine vapor. After marking the spots were scraped off and counted for radioactivity in a liquid scintillation counter.

      Validated HPTLC method for skin lipids
      Karin ROTHENBUEHLER, E. REICH*, M. HAMBURGER (*CAMAG Laboratory, Sonnenmattstr. 11, 4132 Muttenz, Switzerland)

      CBS 104 5-6 (2010). HPTLC of skin lipids (squalene, triolein, palmitic acid, 1,2-dipalmitoyl-sn-glycerol, stearyl palmitate, cholesteryl palmitate, and cholesterol) on silica gel (prewashed with methanol) first with toluene to a developing distance of 80 mm, then with n-hexane - t-butyl methyl ether - acetic acid 80:20:1 to 45 mm in a twin-trough chamber saturated for 20 min. Detection by dipping in copper(II)sulfate regent followed by heating for 30 min at 140 °C. Densitometric absorbance measurement at 350 nm. Stability of standards and samples during 3 h in solution and on the plate was good. The differences of the hRf values of 7 compounds on 3 plates was good (< 3). The precision of measurement was lowest on HPTLC LiChrospher silica gel plates (RSD of < 5 %, n=9). The linear range for all but two compounds was between 100 and 350 ng/band and correlation coefficients were > 0.9975.

      A planar chromatographic method to detect adulteration of vegetable oils in ghee
      Neelam UPADHYAY*, A. KUMAR, A. GOYAL, D. LAL (*Dairy Chemistry Division, National Dairy Research Institute, Karnal – 132 001, Haryana, India, neelam_2912@yahoo.co.in)

      J. Planar Chromatogr. 27, 431-437 (2014). TLC of (1) cholesterol, (2) cholesterol acetate, (3) beta-sitosterol, (4) campesterol, (5) stigmasterol, (6) ergosterol, (7) alpha-tocopherol and (8) gamma-tocopherol on RP-18 (activated at 105 °C for 5 min) with ether – acetonitrile – methanol 1:2:2. Detection by spraying with 15 % phosphomolybdic acid solution, followed by heating at 100 ºC for 1.5–2 min. The hRF values of (1) to (8) were 17, 13, 14, 15, 16, 21, 26 and 31. The absence of beta-sitosterol in ghee allowed to identify adulterated ghee with other vegetable oils.
