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.
Pharmazie 61, 483-485 (2006). Preparative and analytical TLC of talatisamine, 14-O-acetyltalatisamine, senbusine C, and condelphine on silica gel with toluene - ethyl acetate - diethylamine 9:2:1, and 7:2:1; and chloroform - methanol - ammonia 5:3:1, detection under UV light.
Anal. Chim. Acta 566 (2), 157-166 (2006). Extraction of pyrrolizidine alkaloids from the alkalised crude extract of Symphytum cordatum (L.) W.K. roots as free tertiary bases and polar N-oxides by one-step liquid–liquid partitioning and pre-fractionation by preparative multiple-development TLC on silica gel with chloroform – methanol – 25 % ammonia 50:5:1. Three alkaloid fractions of different polarities were obtained which showed different retention on silica gel: the most polar N-oxides had the highest retention, the tertiary bases had medium retention, and diesterified N-oxides had the lowest retention. Purification of the former fraction, which was reduced into free bases by sodium hydrosulfite, by liquid-liquid partitioning on Extrelut-NT3 cartridge. Further analysis by HPLC – ion-trap MS.
26th IPGA Annual conference, 12 (2010). TLC of berberine in plant extracts and methanolic solutions of a commercially available herbal formulation on silica gel with n-butanol - acetic acid - water 14:3:4. Densitometric evaluation at 435 nm. The method was found to be linear in the range of 8.1-26.9 ng/band. The proposed method was applied to the analysis of different formulations using berberine as chemical marker.
CBS 116, 13-15 (2016). HPTLC of nicotine in e-liquids on silica gel with chamber saturation (with filter paper) for 20 min with toluene – acetone –diethylamine 10:10:1 to the migration distance of 70 mm. Detection under UV 254 nm. Quantitative determination by absorbance measurement at 260 nm. Elution of the zones with methanol (with 0.1 % formic acid) into a single quadrupole MS and detection in positive ionization mode. The hRf value of nicotine was 56 and separation from other ingredients (propylene glycol, glycerol, flavors) was good. Visual evaluation of the samples for presence of nicotine was confirmed with MS and UV spectra.
J. Planar Chromatogr. 30, 142-147 (2017). 2D-HPTLC of eleven alkaloids: allocryptopine (1), berberine (2), boldine (3), chelidonine (4), glaucine (5), papaverine (6), emetine (7), columbamine (8), magnoflorine (9), palmatine (10), and coptisine (11) on bilayer Multi-K CS5 with methanol – water 4:1 containing 0.05 mL (volume not clear) diethylamine in the first dimension, followed by drying at 110 ºC for 40 min and developing in the second dimension with methanol – acetone – diisopropyl ether – ammonia 18:18:63:1. Quantitative determination at UV 366 nm. The LOD and LOQ were 25 and 63 μg/zone for (2), 14 and 42 μg/zone for (9).
Phytochemistry 21, 2389-2392 (1982). TLC of various indole alkaloids on silica with ethyl acetate - chloroform - methanol 5:1:1 or ethyl acetate - ethanol 3:1. Detection with ceric ammonium sulfate or with Dragendorff reagent. Also PLC and column chromatography.
Codeine isomers. Acta Chimica 114, 63-68 (1983). TLC of codeine isomers (iso-, pseudo- and allopseudo codeine) on silica with a) benzene - methanol 6:2 or 1:1, b) chloroform - acetone - diethylamine 5:4:1. Detection with Dragendorff reagent.
Preparation of new 6-substituted-6-demethoxy-thebaine derivatives. Acta Chimica 117, 307-312 (1984). TLC study of new 6-substituted derivatives obtained as unexpected products in the nucleophilic substitution reactions: 14-chlorocodeine, 6-o-tosyl-codeine, 6-o-tosyl-14-bromocodeine, 6-chloro-demethoxythebaine, 6-tosyloxy-deme-thoxythebaine on silica with benzene - methanol 8:2. Detection with Dragendorff reagent.
