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. High Resol. Chromatogr. 6, 617-620 (1983). HPTLC of bile acid methyl esters on silica and octadecyl-bonded silica with different solvent systems, e.g. methanol - water 95:5, 9:1, 8:2; acetonitrile-water 95:5, 85:15, 75:25; hexane - ethyl acetate - acetic acid 20:10:0.5, 10:20:0.5, 10:40:2, hexane - isopropanol - acetic acid 50:10:1, 40:10:1, 30:10:1. late development with an appropriate solvent system for 6 cm. Detection by spraying with 0.5 % vanillin in sulfuric acid-ethanol 4:1 and heating at 100 °C.
J. Chromatogr. 355, 427-433 (1968). TLC of 7-carboxymethyl steroids on silica with a) hexane - ethyl acetate 3:7, b) benzene -ether 6:4 or 3:7, c) hexane - ethyl acetate - dichloromethane 25:60:15 or 3:5:3. Comparison with HPLC.
J. Agric. Food Chem. 38, 979-981 (1990). TLC on prechanneled plates (with differing widths and preadsorbing spotting zone with hexane for 16 - 18 h in a developing tank allowing the evaporation of the solvent. After drying immediat development to a height of 12 cm in a tank saturated with a freshly prepared solution of 1.5 % methanol in benzene. Visualization under UV 254 nm. GC after extraction.
J. Chromatogr. 581, 119-128 (1992). TLC of zeranol and estradiol on silica with methylene chloride - methanol - 2-propanol 97:1:2. Detection by spraying with 0.05% aqueous solution of Fast Corinth V and exposing to NH3 vapor for 30 s. Investigation of several dyes for their chromogenic interactions with the compounds to improve the sensitivity and the selectivity, with Fast Corinth V being the best. Detection limit 2 ng.
Chromatographia 41, 175-177 (1995). TLC of steroids on NH2-bonded silica with chloroform - ethanol 19:1. Enhancement of the sensitivity of determination twofold by measuring fluorescence in situ after dipping the chromatogram into a mixture of hexane - paraffin 2:1, and/or using a filter cutting emission wavelengths below 400 nm. Detection limit about 5 ng/spot.
60th Indian Pharmaceutical Congress PA-197, (2008) HPTLC of medroxyprogestrone acetate in bulk and injectable dosage form on silica gel with toluene - ethyl acetate - ammonia 800:200:1. Quantitative determination by absorbance measurement at 240 nm. The linearity was in the range of 50-1800 ng/spot. Recovery was 100.1 %. In the stability test (acid, base, peroxide, thermal, photodegradation) the compound was well separated from degradation products. The method was suitable for routine quality control and for monitoring stability.
Advances in Liquid Chromatography, Sept., 3-6 (1988), Szeged, Hungary. TLC of testosterone, 5-dehydroandrosterone and androsterone on cyano- and amino- modified precoated silica with hexane - acetone 80:20. Detection by fluorescence at 360 nm after spraying with 5 % perchloric acid in methanol and heating at 110°C for 5 min.
Phytochemical Analysis 4, 76-81 (1993). TLC of fractions issued from an ethyl acetate extract of Mandevilla velutina (Apocynaceae) on silica with hexane - chloroform 1:4. Isolation of a new pregnane type steroid by PTLC on silica with hexane - diisopropyl ether - acetone 4:4:3. Detection with 10% sulfuric acid in methanol, followed by 3% phosphomolybdic acid in methanol.
