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.
Indian Drugs 41 (1), 46-47, 2004. HPTLC on silica gel plates with n-propanol - formic acid - water 90:1:9. Rf of berberine was 0.39. Quantification by densitometry at 348 nm via linear regression in the range of 40-220 ng. Limit of quantification and limit of detection were found to be 30 ng and 10 ng, respectively. The herbal extract was found to contain 0.402 % w/w of berberine. The percentage of berberine in formulations I, II, III and IV were 0.0886 %, 0.0123 %, 0.0283 % and 0.0091 % w/w, respectively. The standardized method was found to be reproducible, accurate, precise and selective.
J. Planar Chromatogr. 17, 156-158 (2004). HPTLC of eight 8-alkyltheophyllines (theophylline, methyl-, propyl-, butyl-, heptyl-, tridecyl-, benzyl-, phenylethyltheophylline) on RP18 with mixtures of methanol and phosphate buffer pH 7.5 (containing between 50 and 90 % methanol). Detection under UV at 280 nm.
J. Planar Chromatogr. 17, 61-64 (2004). HPTLC of celecoxib and loratadine (as internal standard) on silica gel after prewashing and bandwise application with n-hexane - ethyl acetate 3:2 in a twin-trough chamber and equilibration for 10 min. Quantitative determination at 262 nm. Mean recovery 100.03 %.
J. Planar Chromatogr. 17, 229-232 (2004). HPTLC of progesterone on silica gel in an automatic multiple development chamber (AMD) with toluene - 2-propanol 9:1 without chamber saturation and with 10 min drying time. Visual inspection under UV light at 254 nm. Quantitative determination in reflectance mode at 252 nm. Limits of quantitation and detection were 25 and 5 ng/zone.
J. Planar Chromatogr. 17, 238-240 (2004). HPTLC of aceclofenac and mosapride citrate (as internal standard) on silica gel in a twin-trough chamber equilibrated with the mobile phase with toluene - methanol - ethyl acetate - glacial acetic acid 550:250:200:1. Quantitative determination by densitometry at 284 nm.
J. Pharm. Biomed. Anal. 40, 68-74 (2006). Two TLC methods have been developed for the screening of fake (counterfeit) drugs of macrolide antibiotics. TLC on silica gel with ethyl acetate - n-hexane - ammonia 20:3:3 for 14 membered macrolides and trichloromethane - methanol - ammonia 100:5:1 for 16 membered macrolides. Detection by spraying with KMnO4 solution. Different chromatographic conditions were standardized and results of color reactions and TLC were correlated to judge the counterfeiting. The method was evaluated in five different laboratories in China.
Abstract G-33, IPC (2005). HPTLC of epalrestat in plasma on silica gel with ethyl acetate - toluene - acetic acid 30:20:1. Nitrofuranloin was used as internal standard. Quantitative determination by absorbance measurement at 390 nm. Linearity was obtained the range of 0.01-0.20 µg/mL with recovery of 99-107 %. The method was validated as per ICH guidelines.
J. Planar Chromatogr. 18, 19-22 (2005). TLC of desloratadine (8-chloro-6,11-dihydro-11-(4-piperidinylidene)-5H-benzo[5,6]cyclohepta[1,2-b]pyridine) on silica gel with ethyl acetate - n-butanol - 25% ammonia - methanol 21:5:4:5. Quantitative determination by absorbance/reflectance measurement at 279 nm. Peak area was linearly dependent on the amount of desloratadine within the range of 1500 to 5000 ng/spot. The relative process standard deviation was 1.78 %.
