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.
Proc. 9th Internat. Symp. Instr. Chromatogr., Interlaken, April 9.-11., 321-324 (1997). OPLC of BHA, BHT, NDGA and propyl, octyl, and dodecyl gallate on silica with 5 different solvent mixtures (chloroform - methanol, chloroform - methanol - acetic acid, benzene - hexane - acetic acid, benzene - methanol - acetone - acetic acid, methanol - acetone - water). The optimum composition of which were chosen by means of the "Prisma" model. Detection by densitometry.
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. Food Hyg. Soc. of Jap. (Shokuhin Eiseigaku Zasshi) 30, 321-323 (1989). TLC of dibutyltin compounds and tricresyl phosphate on silica with acetone - acetic acid 1:100 and benzene. Detection by spraying with 0.5% hematoxylin in ethanol or 0.1% aqueous pyrocatechol violet solution and by exposure to iodine vapor, respectively. Detection limits 50 ng and 250 ng, respectively.
J. Chromatogr. A 708, 143-160 (1995). TLC on silica using successive development with tetrahydrofuran, chloroform - methanol 4:1, toluene and pentane. Distinguishing the pitch fractions by relative retention, and characterization by the title techniques. The method leads to structural information not readily available by direct characterization of the original mixture.
Journal of Ethnopharmacology 163, 192-202 (2015). TLC of the aqueous extract (crude vs. after tannin removal on a polyamide column) of the kino (red hydrosoluble exudate) of Pterocarpus erinaceus on silica gel with s-butanol – water – acetic acid 14:5:5. Detection with vanillin-hydrochloric acid reagent revealed catechic tannins and related polyphenols as dark pink zones. These compounds showed hRfs between 0 and 40, and above 60 in the case of the crude extract, whereas they almost did not appear in the tannin-free fraction. The extracts were also submitted to HPLC-HRMS, allowing the identification of epicatechin monomer in both extracts and of oligomers in the crude extract only.
J. Planar Chromatogr. 9, 16-24 (1996). TLC of a coal tar pitch on silica with pyridine followed by N,N-dimethylformamide (I) and THF followed by toluene as solvent system after chamber saturation for 30 min; first development 2 - 3 cm, after removal and drying development in the second solvent for a further 2 - 3 cm beyond the first solvent front. Separated sample fractions were examined by size exclusion chromatography, UV-absorbance, and UV-fluorescence spectroscopy.
J. Chromatogr. A 1217(34), 5470-5476 (2010). Description of a combination method using high-speed counter-current chromatography and TLC as an antioxidant assay to separate antioxidant components from the fruits of Psoralea corylifolia by dipping in a ethanolic DPPH radical solution (2.54 mM) for autography. Bands with the DPPH scavenging activity were observed as white yellow bands on a purple background. High-speed counter-current chromatography of five flavonoids and three coumarins from the fruits of P. corylifolia with n-hexane - ethyl acetate - methanol - water 10:11:13:1. Preparative TLC for clean-up improves the substance yield from the fruits.
J. Planar Chromatogr. 5, 417-423 (1992). A rapid planar size exclusion chromatographic method has been developed for analysis of the molecular mass distribution of bitumen. The main aims of the work were to determine optimum conditions for such analysis, quantify the technique if possible, and to determine whether the method could distinguish between bitumens of different grades and from different refineries. A case study is briefly described. Relative precision (repeatability) is ca. ± 5%.
