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.
Chinese J. Chromatogr. (Sepu) 12, 134-136 (1994). TLC of porphyrin derivatives on silica with 7 different solvent systems.
J. Liq. Chrom. & Rel. Technol. 26, 3453-3462 (2003). HPTLC of caffeine and acetaminophen on silica gel in a saturated twin-trough chamber with ethyl acetate - glacial acetic acid 19:1. Quantification at 254 nm. Diphenhydramine, pseudoephedrine, and acetaminophen were well separated from the caffeine zone. Precision (relative standard deviation) was 1.19 %; limit of detection was 0.2 µg for caffeine and 0.08 µg for acetaminophen; precision of duplicate samples (RSD) ranged from 0.95 to 7.56 %.
Detection under UV light at 366 nm.
Eur. J. Clin. Chem. Clin. Biochem. 31, 617-624 (1993). TLC of porphyrin methyl esters (uroporphyrin, heptacarboxylic, hexacarboxylic, pentacarboxylic porphyrin, coproporphyrin) on silica with hexane - dichloromethane - acetone 41:41:18. Separation of coproporphyrins I-IV after hydrolysis by HPLC.
J. Planar Chromatogr. 19, 393-397 (2006). TLC of uroporphyrin I, uroporphyrin III, coproporphyrin I, coproporphyrin III, and protoporphyrin IX (as methyl esters) on polyamide 11, cellulose and silica gel with methanol, ethanol, propanol, butanol, acetonitrile and tetrahydrofuran in a saturated chamber. Porphyrins on cellulose were detected by placing in iodine vapor for 5 min; on silica gel and polyamide 11 the porphyrins were detected as red spots in UV light at 254 nm. Chromatographic retention data and a possible retention mechanism are discussed.
J. Chromatogr. 358, 307-312 (1986). HPTLC of haematoporphyrin IX on octyl-bonded silica with methanol - phosphate buffer (pH 3) 85:15. Examination by densitometry. Purification by multi-step extraction and RP-preparative column chromatography. The purity of the resulting material was checked by HPTLC as well as HPLC and MS.
J. Planar Chromatogr. 9, 435-438 (1996). TLC of several crown ether derivatives of tetraphenylporphyrin (18-crown-6, 15-crown-5, 12-crown-4, 14-crown-4, -p- and -o-isomers ) on silica, alumina, and cellulose with different organic mobile phases in different proportions. Detection via the intense color of the porphyrins, examination under UV 254 or 305 nm.
Acta Chrom. 12, 226-233 (2002). TLC of porphyrins and their complexes with Cu (II) and Ni (II) on silica gel (activated at 120 ºC for 30 min) with carbon tetrachloride – chloroform 1:1 after chamber saturation for 30 min. After drying the plates at RT, spots were visible on the plates. The effects of Cu (II) and Ni (II) cations on the separation of hydroxy and alkyloxy tetraphenylporphyrin derivatives were determined.
