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.
J. Chromatogr. 351, 140-143 (1986). HPTLC of plant extracts containing conessine and related alkaloids on silica with ethyl acetate - hexane - diethylamine 75:24:6. Detection with Dragendorff and iodo-platinate reagents. Densitometric determination at 500 nm. Detection limit 40 ng. Data obtained were compared with those obtained by GLC and showed little difference.
J. Chromatogr. 408, 445-448 (1987). TLC of ecdysone, makisterone A, polypodine B, ponasterone A, ponasterone C and polypodine B 2-cinnamate on silica with various solvent systems based on hexane - dichloromethane and dichloromethane - methanol using AMD. Detection by visualizing under UV 254 nm; densitometry by absorbance at 260 nm. Comparison of the results with those from manual multiple development and single development.
Biomed. Chromatogr. 2, 189-192 (1987). HPTLC of androgens, corticosteroids, mineral-ocorticoids and gestagens on silica with dichloromethane - isooctanol - isopropanol 70:25:5 and diethyl ether - isooctane - isopropanol 70:25:5. Detection by spraying with cinnamic aldehyde, 4-dimethylaminobenzaldehyde and sulfuric acid. Detection limits, 500 pg ˜ 1 ng. Comparison with GC.
Thin-layer and high performance liquid chromatography of tetrakis(cyclopentadienyl)di-(aryloxy-µ-oxodizirconiums.) (Chinese). Chinese J. Chromatogr. (Sepu) 7, 282-285 (1989). TLC on silica with petrol ether - acetone 15:1, 10:1 and 7:1, or cyclohexane - dichloromethane 25:1. Detection under UV. Determination of Rf values. Study of the behavior of different substitutions. Comparison with the results from HPLC.
J. Liquid Chromatogr. 13, 2737-2755 (1990). Comparison of separations attained in normal phase HPLC and TLC involving N-carbobenzyloxy-glycyl-L-proline and (+/-)-10-camphorsulfonic acid as chiral mobile phase additives/chiral counterions (CMA). Discussion of the reasons for differences in chiral stationary phases, and of the differences in solubility and proposed separation mechanisms for native cyclo dextrin versus derivatized species. Outline of inherent differences in HPLC and TLC methods.
J. Liquid Chromatogr. 16, 497-511 (1993). TLC of cucurbitacins on silica with ethyl acetate - toluene 75:25, and on RP-18 silica with methanol - water 7:3. Quantification by densitometry. Also HPLC.
J. Planar Chromatogr. 7, 5-9 (1994). HPTLC of strictosamide on silica with chloroform - acetone - methanol 65:25:10. After development, plates were heated at 105°C for 24 h in order to transform strictosamide into a highly fluorescent derivative. Quantification by fluorodensitometry 366/>400 nm. HPTLC and HPLC gave similar results but the sensitivity of HPTLC was higher by factor 4. Detection limits 2.5 and 11 ng, resp..
TLC as valuable instrument for preliminary proceedings suitable for chromatographic systems in HPLC separation problems. Reasons and preconditions for TLC as pilot procedure are given. 62 pesticides of 6 different substance classes, i.e. triazines, phenoxycarboxylic acids, urea herbicides, aniline derivatives, phosphoric acid esters, etc., are used for transmission of retention characteristics to HPLC. TLC of triazines on RP-8 with acetonitrile - water 3:2, of phenoxycarboxylic acids on RP-18 with acetonitrile - water - acetic acid 15:9:1, of urea herbicides on CN with hexane - tetrahydrofuran 3:2, of aniline derivatives on NH2 with hexane - tetrahydrofuran 7:3, of phosphoric acid esters on silica with hexane - tetrahydrofuran 3:2, of further pesticides on diol with hexane - tetrahydrofuran 7:3.
