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.
International Journal of ChemTech Research 2(1), 646-652 (2010). TLC on silica gel with toluene - methanol - triethylamine 9:3:1 with chamber saturation for 30 min. The hRf value was 71. Densitometric evaluation at 282 nm. The method was linear in the range of 100-2000 ng/band with r2 = 0.9973. The repeatability of sample application and measurement of peak area (%RSD, n=6) was 0.461 % and 0.363 %. The %RSD for intra-day and inter-day variation was 0.752-0.961 % and 0.848-1.082 % respectively. The LOD and LOQ was 10 and 50 ng/zone, respectively. The average recovery was 99.5 %. The samples were subjected to stress conditions (acid, base, oxidative, thermal) and all degradation products were well resolved from the main compound. The method was found suitable for stability studies and for routine analysis of the drug in biological fluids.
J. Planar Chromatogr. 27, 132-139 (2014). HPTLC of levetiracetam on silica gel with toluene - ethyl acetate - methanol 2:1:1. Quantitative determination by absorbance measurement at 204 nm. The hRF value for levetiracetam was 50. Linearity was in the range of 1-1000 ng/zone. The intermediate/interday/intra-day precisions were below 1 % (n=6). The LOD and LOQ were 30 and 100 ng/zone, respectively. Recovery was between 99.2 and 100.9 %.
Planta Med. 55, 367-371 (1989). TLC on silica with hexane - ethyl acetate 2:1. Detection under UV 254 nm and by spraying with anisaldehyde - sulfuric acid reagent.
Biochemical Systematics and Ecology 24, 43-47 (1996). TLC of alkamides on silica with hexane - ethyl acetate. Identification by MS.
Asian Journal of Chemistry 22(8), 5951-5955 (2010). TLC on silica gel with cyclohexane - methanol - ethyl acetate - 25 % ammonia 10:3:6:1. The hRf value was 7 for atenolol and 69 for nifedipine. Densitometric evaluation at 230 nm. The linearity was in the range of 3-21 µg/band for atenolol and 1.2-8.4 µg/band for nefidipine. The recovery was 100.7 % for both drugs. The method was found suitable for analysis of the combined dosage form of atenolol and nefidipine without interference of excipients.
HPTLC-UV densitometry
Food Addit. Contam. 31, 15-20 (2014). HPTLC of sibutramine in food supplements and soluble beverages on silica gel with toluene - methanol 9:1. Quantitative determination by absorbance measurement at 225 nm. The hRF value for sibutramine was 53. Linearity was in the range of 78-3020 ng/zone. The method was sensitive to detect 0.3 mg of sibutramine per capsule of food supplement and showed comparable results with those obtained with HPTLC-UV and HPLC-MS.
J. of Plant Physiology 133, 299-303 (1988). TLC of cynamide and its metabolites on silica with acetonitrile - NH3 (25%) 95:5 and butanol - acetic acid - water 4:1:1.
Chinese J. Chromatogr. (Sepu) 14, 317-318 (1996). TLC on silica with dichloromethane - methanol 10:1. Detection by exposure to iodine vapor. Identification of dichloroacetamide compounds by comparison of the Rf values.
