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.
(About the detection of the content of a type of mushroom of the class of panaeolus.) Pharmazie 40, 431-432 (1985). 100 samples from a panaeolus foenisecii species analyzed by TLC on silica with butanol - water - acetic acid - isopropanol 8:5:2:3; staining with Ehrlich reagent. Psilopsibine not found, but indole derivatives such as tryptamine, 5-oxy-tryptamine, 5-hydroxy-indole acetic acid.
(Simple qualitative determination of pharmaceutical active ingredients in urine.) Swiss Pharma 8, 6-17 (1986) Qualitative identification of 19 drugs by 1. isolation from the matrix, 2. separation from accompanying substances using TLC and 3. detection (i. a. via fluorescence and fluorescence quenching, chemical reaction. TLC on silica with toluene - isopropanol - NH3 3:6:1. Detection with trichlorobenzoquinone imine, Dragendorff reagent, diphenylcarbazonel mercury II, UV 366 nm.
J.A.O.A.C. 70, 842-844 (1987). TLC on HPTLC silica with hexane - methanol 95:5. Quantification after treatment of the plate with fluorescence-enhancing spray consisting of 15% AlCl3 in ethanol and silicane - ether 18:82. Method acc. to O.J. Francis et al., J.A.O.A.C. 68, 643-645 (1985).
J. of Natural Products 51, 966-968 (1988). TLC identification of (5-hydroxy-6,7,3',4',5'-penta-methoxyflavone) on silica with butanol - benzene 2:8. Visualization under UV and by spraying with 10% SbCl3 in chloroform.
J. Planar Chromatogr. 2, 86-89 (1989). TLC and OPLC of formaldemethone and dimedone on silica with chloroform - dichloromethane 35:65 and with acetone. Densitometry by absorbance at 275 nm without and at 535 nm after derivatization with Dragendorff’s reagent.
J. Planar Chromatogr. 3, 336-339 (1990). TLC of diphenylamine, carbazole, indole and p-dimethylaminobenzaldehyde on silica, alumina, and silica mixed either with alumina or cellulose using cyclohexane and benzene in various proportions as mobile phase. Separation of carbazole from diphenylamine has been achieved on alumina with cyclohexane - benzene 1:1.
J. Planar Chromatogr. 6, 112-116 (1993). The use of the colorimeter for standardization of color measurement in thin-layer chromatography, and the handling of the data obtained, have been evaluated. The identification power, expressed as the mean list length (MLL), was 8.32 and 6.34 for visual and colorimetric methods, respectively. When fluorescence measurements were included in the encoding system, the MLL obtained from visual coding dropped dramatically to 2.90. The colorimeter tested was not able to measure UV reflection.
Part 3. Identification of drugs and their metabolites by PCA of standardized TLC data. J. Planar Chromatogr. 7, 233-241, (1994). Principal components analysis of standardized Rf values of 443 drugs and their metabolites chromatographed with four eluent systems provided a two-component model accounting for 70.8% of the total variance. The "scores" plot enabled either identification, or restriction of the range of inquiry to few candidates. This simple, cheap and fast analytical method is of vital importance in the identification of an unknown drug in cases of overdose intoxication or poisoning, and is particularly valuable in the unaided search for drugs and their metabolites in instances when the substance is very polar and cannot be identified by gas chromatography.
