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. Chromatogr. 645, 161-167 (1993). Preparative TLC of short-chain (C5-C20) isoprenoid diphosphates on silica with isopropanol - conc. NH3 - water 13:5:1 and 6:3:1. Detection by spraying with either water - anisaldehyde solution ormolybdenum reagent. Also, flash chromatography. From a single TLC plate up to 20 mg pure farnesyl diphosphate can be isolated.
J. Chromatogr. A 1211 (1-2), 49-54 (2008). Presentation of a spreadsheet that provides information on the amount of silica gel needed, the optimal fraction size, and the degree of separation to be expected before flash chromatography is attempted. Information is based on sample mass and TLC data given. This is the first utility of its kind to accurately estimate the retention volume and band volume of analytes, as well as the fraction numbers expected to contain each analyte, and the resolution between adjacent peaks. The information allows users to select optimal parameters for preparative-scale separations before the flash column itself is attempted; ensuring a successful first separation.
Z. Anal. Chem. 330, 529 (1988). Preparative TLC on silica for separation of wax in principal fractions: 1st run for obtaining alkanes in CCl4; 2nd run for separation of esters, aldehydes, ketones and alcohols in chloroform; 3rd run in chloroform/1% acetic acid for separation of acids. Visualization by spraying with 0.1 mmol ethanolic solution of 8,1-ANS(8-(phenylamino)-1-naphthalenesulphonate).
Chinese J. Petrol. Proces. (Shiyou Lianzhi) 24, 59-63 (1993). Preparative TLC of antioxidants on silica with non-polar solvent systems. Detection by spraying with palladium chloride reagent. Identification by IR and NMR.
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.
J. High Resol. Chromatogr. 10, 588-593 (1987). TLC purification of limonene hydroperoxides on silica with hexane - ether 9:1. Detection with potassium iodide/starch solution, then extraction with pentane - ether 2:1.
J. Chromatogr. 684, 370-373 (1994). Description of a micro-preparative TLC system. Quantitative elution of the separated spots or linear zones with a fast-moving drill, and by siphoning eluent through a specially formed sintered glass onto one end of the zone or spot and picking up the eluate at the other with a piece of filter-paper carton. Extraction of the latter by soaking and centrifugation. Demonstration of the application in the carbohydrate field.
Anal. Chem. 56, 595-597 (1984). Description of an indexing device for scraping bands of 5 or 10 mm width from TLC plates.
