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.
(Adulteration, confusion or replacement drug? Carlinae radix.) Deutsche Apotheker Zeitung 130, 2186-2190 (1990). TLC of plant extracts on silica with toluene - ethyl acetoacetate - methanol - acetic acid - 60:15:15:10. Detection by spraying with 1% vanillin in 70% sulfuric acid. Visualization under UV 254 nm.
J. Chromatogr. 570, 396-398 (1991). TLC of 17-oxosteroids on silica developed twice with chloroform – ethanol 97:3. Quantification by fluoro densitometry at 310 nm.
J. Planar Chromatogr. 4, 337-338 (1991). TLC of aminophenazone on silica with chloroform - ether - methanol 7:5:1. Measurement of the absorbance after extraction against reference solution (extraction of the ion associate of iron (III) with 1,10-phenanthroline and bromophenol blue).
J. Liquid Chromatogr. 16, 1819-1831 (1993). TLC of major phospholipid classes on silica with chloroform - methanol - ethyl acetate 40% methylamine 2:2:2:1. Detection by heating at 180 °C for 3 min., spraying with 10% H3PO4, and charring at 180 °C for 20 min. Quantification by densitometry at 400 nm.
J. Planar Chromatogr 7, 278-285 (1994). Study of the influence of the temperature, ionic strength, and apparent pH of the eluent to find an improved protocol for the analysis of conjugated bile acid. Comparison of the performance of different silica layers and variations of eluents at different temperatures. TLC at low temperature, the use of RP plates and the substitution of acetic acid with tetrahydrofuran leads to improvement of band shape, intensity and resolution.
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.
Biomed. Chromatogr. 10, 144-145 (1996). TLC on silica with ether - acetone - water - acetic acid - isooctane 70:25:3:15:40. Detection by spraying first with 1 N NaOH - methanol 1:3 and then with Folin ciocalteau reagent - water 1:4. Quantification by densitometry at 600 nm, and using b-(4-hydroxy-3-phenyl), acetic acid as internal standard. The sample was cleaned up through a cyano minicolumn and extracted with ether.
J. Planar Chromatogr. 18, 400-402 (2005). HPTLC of beta-carotene on silica gel and RP-18 with preadsorbent sample-application zones (prewashed with dichloromethane - methanol 1:1) with petroleum ether (35-60 °C) - acetonitrile - methanol 1:2:2 or petroleum ether (20-40°C) - acetone 7:3. HPTLC of biliverdin on silica gel with n-butanol - methanol - water 4:2:3. Quantitative determination by absorbance measurement at 628 nm.
