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.
Acta Chimica 126, 81-97 (1989). TLC of 2-methylenecephalosporins on silica with benzene - ethyl acetate 1:1 and benzene - ethyl acetate - acetic acid 7:3:1. Visualization under UV and by exposing to iodine vapor.

Chinese J. Pharm. Anal. (Yaowu Fenxi Zazhi) 8, 348-349 (1988). TLC of secoiridoids on polyamide with ethyl acetate - methanol 5:1. Detection under UV 254 nm or 365 nm. Identification by comparison of the Rf values and spot colors with standards.
J. Chinese Herb Med. (Zhongcaoyao) 21, 148-150 (1990). TLC of organic acids on silica with ethyl ether - chloroform - formic acid - methanol 10:4:3:1. Detection by spraying with 0.02% bromophenol blue in ethanol and heating for 2 h at 120°C. Quantification of ursolic acid by densitometry at 430 nm.
Biochemical Systematics and Ecology 17, 5-10 (1989). TLC of Dragendorff-positive compounds on silica and cellulose with butanol - acetic acid - water 12:3:5 or 8:2:2, phenol - water 3:1. Visualization with Dragendorff’s reagent, ninhydrin, by exposing to iodine vapor and under UV 254 nm.
J. Chromatogr. 489, (1989). TLC of anabolics on silica with chloroform - acetone 9:1 and cyclohexane - ethyl acetate - ethanol 31:8:1. Detection by spraying with 10% sulfuric acid in methanol and heating for 10 min. at 90°C, and under UV 366 nm. Identification by comparing Rf values and color of the spots.
Chromatogr. Sci. 49, 85-106 (1990). A review with 87 references on the sorbents, mobile phases, sample applications, development techniques used in pharmaceutical analyses, etc.
J. Planar Chromatogr. 2, 203-206 (1989). The chromatography of six N-oxides (nicotinic acid N-oxide, metyrapone N-oxide, p-cyano-N, N-dimethyl aniline N-oxide, 3-acetyl pyridine N-oxide, 3-benzylpyridine N-oxide, and pyridine N-oxide) was described for both C-18 and CN-bonded silica gel TLC plates. Using methanol-water solvent systems containing up to 60% methanol the N-oxides had higher Rf values than their respective parent compounds. At concentrations of methanol of 80% or more the order of migration was reversed. Separation of critical pairs was possible by careful selection of one or other of the phases.
