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.

Detection by exposure to iodine vapors. Determination of tetrahydropalmatine before and after pernetration by spectrophotometry. Discussion of the effect of azone concentration added.
Arzneim.-Forsch./Drug Res. 48, 995-1006 (1998). TLC of metabolites of S-8921 (methyl 1-(3,4-dimethoxyphenyl)-3-(3-ethylvaleryl)-4-hydroxy-6,7,8-trimethoxy-2-naphthoate) on silica gel with benzene - dioxane - acetic acid 40:5:1 and on RP-18 with methanol - water - acetic acid 90:10:0.1. Detection of radioactive spots with an imaging plate and semiquantitative analysis using BAS 2000 (Fuji Film).
Lipids 17, 477-482 (1982). Preparative TLC of microbially produced metabolites of lithocholic acid and lithocholic acid-3 alpha-sulfate on silica with dichloromethane-methanol 95:5. Detection by spraying with anisaldehyde, followed by heating. The following metabolites were isolated: isolithocholic acid, 5 beta-cholanic acid, 3-keto-lithocholic acid, 5 alpha -cholestone and delta 3-cholenic acid.
Detection and determination of some beta-receptor blockers in urine by instrumental TLC. Fresenius Z. Anal. Chem. 330, 458-459 (1988). TLC on silica with ethyl acetate - methanol (saturated with formic acid) - water 800:200:1, two runs. Densitometry by fluorescence 366/>410 nm. Additional identification by 3 spray reagents: 1) 0.5 % fast blue B in water, 2) 0.2 % naphthoquinone-1,2- sulfonic acid Na salt in ethanol - water 1:1 and 3) formaldehyde in sulfuric acid followed by heating at 110°C. Acebutolol, Alprenolol, Atenolol, Carazolol, Labetolol, Metoprolol, Oxprenolol, Propranolol and Sotalol can be identified by different colors. Screening method for low concentrations of beta-blockers (reaction chromatography): 100 µL urine extract sprayed onto HPTLC silica; overspraying with dansylchloride in acetone, then with sodiumhydrogenecarbonate in water; heating for 15 min at 120 °C; then chromatographic development with acetone - chloroform 9:1. Evaluation by densitometry (fluorescence 366/>410 nm); detection limit 10 ng. The method of analysis is available as CAMAG Application booklet (in preparation).
