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.
Phytochemistry 29, 247-249 (1990). TLC of various coumarin glycosides on silica with chloroform - methanol solvent mixtures. Detection by UV 254 and 365 nm. Preparative TLC of acetylated derivatives on silica with concentrating zone (layer thickness 2 mm) with benzene - methanol 20:1. Also column chromatography.
J. Planar Chromatogr. 3, 439-441 (1990). TLC of furocoumarins on silica and micropreparative TLC on Florisil and silanized silica with binary or ternary mixtures of nine different solvents. Detection under UV 366 nm. Quantification by HPLC after elution.
Phytochemistry 33, 1485-1487 (1993). 2D-TLC of tannin polymer hydrolysates on cellulose with 1) tert-butanol - acetic acid - water 3:1:1 and 2) 6% aq. acetic acid. Detection with 4% vanillin in methanol - conc. HCl 4:1.
Phytochemistry 42, 857-762 (1996). TLC of new proanthocyanidins on silica with ethyl acetate - formic acid - water 18:1:1. Detection with vanillin - HCl reagent of 1 % ethanolic FeCl3 solution. Isolation of acetylated derivatives by prep. TLC on silica with toluene - acetone 7:3.
Proc. Intern. Symp. on Planar Separations, Planar Chromatography 2001, pp. 363-371. HPTLC of selected flavan-3-ols [(-)-epicatechin-3-gallate, (+)-catechin, (-)-epicatechin and (-)-epigallocatechin] on cellulose with aqueous solutions of sodium chloride (10 mg/ml) containing different concentrations of b-cyclodextrin. Acetone and 1-butanol were used as organic modifiers. An unsaturated horizontal developing chamber was used for the separations. Detection under UV 366nm. After that the spots were visualized by dipping the plates in anisaldehyde-sulfuric acid reagent. A Video Documentation System was used for recording and analyzing the images of the developed TLC plates.
Planta med. 66, 403-407 (2000). Preparative TLC of machilusol A, B, C, D, E, and F on silica gel with n-hexane - acetone 1:1, dichloromethane - acetone 10:1 and dichloromethane - ethyl acetate 10:1. Visualization by spraying with cerous sulfate solution, detection by heating.
J. Chromatogr. A 1077 (2), 188-194 (2005). HPTLC of (+)-catechin (C), (-)-epicatechin (EC), (-)-gallocatechin (GC), (-)-epigallocatechin (EGC), (-)-epicatechin gallate (ECg), (-)-epigallocatechin gallate (EGCg), procyanidin B1, and procyanidin B2 on cellulose prewashed with water (not necessary, when water was used as developing solvent) and dried with a hair dryer, with 1) water; 2) 1-propanol - water 1:4; 3) 1-propanol - water - acetic acid 4:2:1; 4) 1-propanol - water - acetic acid 2:8:1 in horizontal developing chamber (sandwich configuration). Detection with vanillin - H3PO4 reagent. Water enabled the separation of epimers C from EC and GC from EGC, as well as the dimers procyanidin B1 and B2. Additionally C, EGC, B1 and B2 were separated from all the other compounds. The best separation of the five main catechins (EC, GC, EGC, ECg, EGCg) present in green tea extract was achieved using 1-propanol - water - acetic acid 2:8:1. The chromatograms of oak bark extract developed in solvents with higher water content (1-propanol - water 1:4 and 1-propanol - water - acetic acid 2:8:1) showed less bands than chromatograms developed in solvents with higher organic modifier content (e.g. 1-propanol - water - acetic acid 4:2:1). It was proved that such behavior was due to the presence of procyanidins beside the main component catechin.
(The content of coumarin in woodruff and its TLC-determination.) Z. Lebensm. Unters. Forsch. 175, 179-181 (1983). TLC of coumarin on silica with a) chloroform, b) dichloromethane. Detection with 2.5 N NaOH. Fluorometry at 366 nm.
