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. The saved items can be printed to PDF using the print function of your web browser.
J. Planar Chromatogr. 32, 41-46 (2019). HPTLC of ayapanin in the leaves of Ayapana triplinervis on silica gel with ether - ethyl acetate 3:2. Quantitative determination by absorbance measurement at 254 nm. The hRF value of ayapanin was 56. Linearity was between 200 and 1000 ng/zone. The intermediate precision was below 0.8 % (n=6). The LOD and LOQ for ayapanin were 54 and 169 ng/zone, respectively. Recovery rate was 99.7 % for ayapanin.
) wood enzyme extract with catechins. J. Planar Chromatogr. 21, 83-88 (2008). TLC of (+)-catechin and (-)-epicatechin on silica gel with diisopropyl ether - formic acid 91 in an unsaturated twin-trough chamber. Detection by spraying with vanillin-sulfuric acid reagent followed by heating at 120 °C for 5 min. Quantitative determination by absorbance measurement at 490 nm.
CBS 107, 13-15 (2011). HPTLC of 5-hydroxymethylfurfural (HMF) in honey on silica gel, prewashed with methanol - water 61, with ethyl acetate. Quantitative determination by densitometry in absorbance mode at 290 nm. Optional detection by immersion in p-aminobenzoic acid reagent followed by heating at 110 °C for 5-10 min. The hRf value of HMF was 80. The calibration function was polynomial in the range of 0.8-80 ng/band whilst Michaelis Menten 2 regression was suitable for higher concentrations. The LOD of HMF in honey samples was 0.75 mg/kg (12 µL applied) and the LOQ 2.4 mg/kg. The method complies with the requirement of max. 15 mg/kg of HMF in honey. The results with this method were compared with those obtained by the spectrophotometric Winkler method and by HPLC-UV and mean differences were minor (3.3 % or 0.9 mg/kg). Complementary confirmation by HPTLC-MS online coupling. HMF zones identified under UV were eluted and analyzed by ESI-MS in full-scan and SIM mode.
by principal component analysis. J. Planar Chromatogr. 28, 274-279 (2015). DPPH-HPTLC bioautography assay of Hibiscus sabdariffa on silica gel with toluene - ethyl acetate - formic acid - methanol 303085. Analysis by dipping into 0.05 % DPPH methanolic solution. Combination with liquid chromatography-quadrupole time-of-flight mass spectrometry enabled the rapid screening and identification of the antioxidants in Hibiscus sabdariffa.
Planta Medica 83(03/04), 326-333 (2017). Usnic acid, precipitated by low temperature (4 °C) from a benzene Soxhlet extract of the lichen Usnea amblyoclada, was purified by preparative layer chromatography on silica gel with chloroform – n-hexane 41. Detection at UV 254 nm. Yield was 1.1 % of the dried plant.
J. Ethnopharmacol. 233, 141-147 (2019). HPTLC of gentiopicrin in the dried roots and rhizomes of Gentiana scabra on silica gel with ethyl acetate – ethanol – water 821. Detection by spraying with chromogenic reagent (acetic acid – sulfuric acid – p-anisaldehyde 10021). Qualitative evaluation at UV 254 nm. The hRF value for gentiopicrin was 58.
