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. Planar Chromatogr. 19, 383-385 (2006). HPTLC of apigenin on silica gel, pre-washed with methanol, in a saturated twin-trough chamber with toluene - methanol 5:1. Densitometric evaluation at 343 nm.
J. Chromatogr. 294, 431-435 (1984). TLC of methylparaben on silica with the solvent prepared by the organic layer of pentane - ether - water 70:30:100, shaked with 5 ml 85 % formic acid. Detection at 254 nm. Densitometry.
J. Liq. Chromatogr. Relat. Technol. 29, 1503-1514 (2006). TLC of tanshinones (cryptotanshinone, tanshinone I, tanshinone II A) on silica gel with light petroleum (60-90°C) - ethyl acetate 4:1. Evaluation and scanning densitometry at 280 nm. With TLC 8 stable components were separated in common within 48 min, respectively, from 3 crude samples of Salvia miltiorrhiza Bunge from different growth locations. With High Speed Countercurrent Chromatography (HSCCC) 12 components were separated, respectively, with good correspondence and precision within 13 h. Both TLCS and HSCCC were effective in showing the whole concentration distribution of all kinds of constituents in different samples. HSCCC showed better performance in analysis of tanshinones, which produced a fingerprint which contained more chemical information than that of TLCS.
Chem. Anal. (N.Y.), 85, 149-178, (1986). (Ultratrace Anal. Pharm., other Comp. Interest). A review with 55 references on sample preparation for ultratrace drug analysis in conventional, high-performance and reversed-phase TLC, type of plates and mobile phase selection, developing techniques.
J. Sep. Sci. 30, 1250-1254 (2007). HPTLC of Emblica officinalis extract on silica gel with ethyl acetate – formic acid – glacial acetic acid – water 10:1:1:2. Primary detection under UV 280 nm. Antiradical activity of individual components was estimated on intensity of disappearance of violet/purple background of plate after dipping in DPPH radical solution (0.5 mM in methanol) at room temperature for 90 s and that 30 s at 60 °C. Quantitative determination by absorbance measurement at 517 nm as negative peak. DPPH radical scavenging activity of emblicanins A and B was 7.9 and 11.2 times more active than that of ascorbic acid and 1.3 and 1.8 times more active than gallic acid, respectively.
People’s Hygiene Publishing House, Beijing 1990. A book with 222 pages and 186 drawings and photographs, introducing TLC densitometry and the related instrumentations, emphasizing on its applications in pharmaceutical analysis.
J. Chromatogr. 579, 203-207 (1992). TLC of the reaction mixtures in the dansyl hydrazine derivatization of the title compounds on silica with propanol - 2-propanol - butanol - water 30:45:2:20 containing 0.04M NaCl and 0.01M NH3. TLC is used for selection of the extraction solvent for the compounds.
J. Planar Chromatogr. 8, 72-74 (1995). HPTLC of chloroprocaine an 4-amino-2-chlorobenzoic acid on silica (prewashed with methanol) with chloroform - methanol - acetic acid 56:40:4. Quantification by densitometry at 278 nm.
