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. 10, 195-199 (1997). The 'Simplex' and 'Prisma' methods have been compared for optimization of the mobile phase used for the separation of a mixture of 1,4-benzodiazepines. The objective function used contains more than one term and even a second degree term. TLC of medazepam, nitrazepam, chlordiazepoxide, oxazepam, and diazepam on silica with 8 different mobile phases, chloroform - ether - isopropanol (84:13:3 was the optimum). Densitometry at 254 nm.
Acta Pharmaceutica Hungarica 67, 193-199 (1997). TLC on silica. Quantification by densitometry at 254 nm.
J. Planar Chromatogr. 12, 152-154 (1999). HPTLC of nimesulide (4'-nitro-2'-phenoxymethanesulfonanilide) on silica gel with toluene - methanol 4:1. Densitometry at 324 nm. Limit of detection was found to be 0.26 ng/µl. New simple, precise, accurate, rapid and stability-indicating determination.
J. Planar Chromatogr. 12, 230-323 (1999). HPTLC of magnesium salicylate and salicylic acid on silica gel with ethyl acetate - acetic acid 19:1. Quantitation after drying by linear densitometry at 252 nm.
J. Planar Chromatogr. 12, 392-394 (1999). TLC of seven intermediates from all steps of the syntheses of oxazepam on silica gel. After cleaning the plate by successive development with chloroform - ethyl acetate 3:1 and aqueous NH3 - methanol 1:9, chromatography with chloroform - acetone and chloroform - ethyl acetate mixtures in different ratios in previously saturated N-chambers. The optimum chromatographic system for related compounds was found to be chloroform - ethyl acetate 3:1. Detection under UV 254nm.
J. Planar Chromatogr. 13, 468-470 (2000). HPTLC of alprazolam, chlordiazepoxide, diazepam, lorazepam, nitrazepam, oxazepam on silica gel with chloroform - acetone 4:1. Detection under UV 254 nm. Visualization by spraying with 1% sulfuric acid and heating at 100°C for 10 min. After cooling, the plate was sprayed with 10% ammonium chloride solution and then, after 5 min, diazotized with sodium nitrite reagent and treated with N-(1-naphthylethylenediamine) in ethanol. Intense violet spots were immediately observed for ClDz, Nz, and Oz. Simple, rapid procedure.
Indian Drugs 39 (2), 91-95 (2002). HPTLC of catechin on silica gel with chloroform - ethanol - ethyl acetate - toluene - formic acid 6:2:4:1:1. Quantification by densitometry at 280 nm. The method was applied to catechu extracts from black tea, green tea, pale and black catechu.
J. Planar Chromatogr. 15, 192-195 (2002). HPTLC of rosiglitazone (and pioglitazone as internal standard) on silica gel after prewashing with methanol with ethyl acetate - toluene - methanol 45:55:1 after equilibration for 10 min. Densitometry at 242 nm. Limit of detection was found to be 40 ng; limit of quantitation 100 ng. New simple, specific, and sensitive method.
