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. Planar Chromatogr. 19, 73-80 (2006). TLC of six atypical antipsychotic drugs (amisulpride, clozapine, olanzapine, quetiapine, risperidone, ziprasidone) on silica gel, amino, cyano, DIOL, and polyamide phases with mixtures of n-hexane and six polar modifiers (acetone, dioxane, diethylamine, ethanol, isopropanol, and tetrahydrofuran) in a horizontal DS chamber. After development the plates were inspected under UV light at 254 nm. Quantification by densitometry.
J. Planar Chromatogr. 19, 449-453 (2006). HPTLC of caffeic, p-coumaric, and ferulic acid on silica gel with dichloromethane - acetonitrile - 90 % formic acid 95:5:1. Quantitative determination by absorbance measurement at 320 nm. The method is precise and accurate.
J. Food Comp. Anal. 19, 118 - 126 (2006). HPTLC of andrographolide (AP) and 14-deoxy-11,12-didehydroandrographolide (DIAP) in the aerial parts of Andrographis paniculata Nees on silica gel with chloroform – methanol 4:1 with chamber saturation for 2 h. Quantitative determination at 254 nm. Good resolution of AP and DIAP was obtained together with symmetrical and reproducible peaks at Rf 0.55 and 0.43, respectively. Linearity is between 10 and 2000 µg/mL; LOD is 3.0 and 3.6 µg/mL; mean recoveries are 97.7 % and 97.8 % and precision analysis shows an intra-assay variation between 0.89 - 0.99 % and an inter-assay variation between 0.86 - 0.98 %. HPTLC method leads to accurate results when compared to the HPLC method.
Acta Chrom. 13, 109-116 (2003). HPTLC of the laxative bisacodyl in enteric-coated tablets on silica gel with concentrating zone and 19 channels, pre-cleaned with dichloromethane – methanol 1:1, with ethyl acetate–methanol–glacial acetic acid 17:2:1. Quantitative determinaion by absorbance measurement at 254 nm. The method was validated and can be used for routine analysis of the pharmaceutical preparation in industry quality control and regulatory laboratories. An alternative extraction procedure and mobile phase are suggested for analysis of bisacodyl tablets with different formulations.
Innovative Food Science and Emerging Technologies 1, 239-243 (2001). HPTLC of commercial herbal spirits (alcoholic or hydroalcoholic solutions of volatile substances with flavoring or medicinal properties) and one red wine on silica gel with toluene – ethyl formate – formic acid 79:20:1. Antioxidative components were detected by dipping for 30 s in a soybean oil solution (3 % in n-hexane, previously treated with active carbon). Quantitative determination in UV light at 254 nm after different times of UV-exposure (30 min – 20 h). The antioxidant activity could be evaluated from the fluorescence-persisting time of the respective spots and was correlated with linoleic acid oxidation and DPPH-titration methods. Although the nature of the active herbal antioxidants remains to be established, phenolic compounds seem to be key candidates.
J. AOAC Int. 90, 857-863 (2007). TLC of azadirachtin on silica gel with dichloromethane - ethanol 20:1. Detection by spraying with acidified vanillin reagent (3 g vanillin in 10 mL ethanol with 1.5 mL concentrated sulfuric acid) followed by heating at 110 °C for 3 min. Quantitation by densitometry.
Phytochem Anal. 18, 229-234 (2007). HPTLC of Artemisia annua leaves on silica gel with hexane – ethyl acetate – acetone 16:1:1. Detection by exposing to ammonia vapor at 100ºC for 2 hours. Quantitative determination by absorbance measurement at 320 nm. Linearity is between 0.5 and 12 µg/mL and the limit of detection is 0.5 µg/mL. The method is as sensitive and accurate as the HPLC-UV method involving a pre-column reaction.
