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:

- 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. 18, 336-343 (2005). HPTLC of thirty-three compounds with benzodiazepine properties on silica gel after prewashing first with methanol and then with dichloromethane - methanol 19:1 in a saturated horizontal chamber and three optimized mobile phases: dichloromethane - methanol 19:1, ethyl acetate - cyclohexane - 25 % ammonia 50:40:0.1, and in a third run cyclohexane - acetone - methyl t-butyl ether 3:2:1. Diode-array HPTLC makes it possible to identify all the compounds with high certainty down to a level of 20 ng. An algorithm for spectral recognition which is combined with Rf values from the three separation steps into one fit factor is presented. This set of data is unique for each of the compounds investigated and enables unequivocal identification.
J. Planar Chromatogr. 19, 250-252 (2006). TLC of piperine and chavicine on silica gel with heptane - ethyl acetate 3:2 in unsaturated chambers. Detection under UV light at 254 nm.
J. Planar Chromatogr. 19, 85-86 (2006). TLC of methomyl on silica gel with benzene - ethyl acetate 3:2 in a presaturated TLC chamber. After drying the plate was sprayed with 1 % phloroglucinol solution then with 50 % hydrochloric acid. The plate was heated at 100 °C for 5 min. Detection limit of the pink-violet spot was 5 µg.
J. Planar Chromatogr. 19, 32-41 (2006). TLC of 11 new derivatives of 1,2,4-triazole and of 18 new derivatives of thiosemicarbazide on RP18 with mixtures of methanol, acetonitrile, and water. Amounts of organic modifiers were in the range of 20-70 % in 10 % increments. After development in horizontal DS chambers and drying, the plates were visualized under UV light at 254 nm.
Indian Drugs 42 (9), 600-603 (2005). HPTLC of cinnarizine and domperidone in tablets, on silica gel with toluene - ethyl acetate - methanol 14:1:5. Quantitative determination by absorbance measurement at 271 nm. Rf values of cinnarizine was 0.85 and of domperidone 0.4. Linearity was observed in the range of 0.1-0.4 for cinnarizine and 0.075-0.3 µg/µL for domperidone. The recoveries were in the range of 98.95-100.25 %. The tablet matrix did not interfere with the assay.
J. Planar Chromatogr. 19, 371-377 (2006). HPTLC of five isoflavone products and 2-phenylchromone as reference standard on silica gel, pre-washed with acetonitrile, in an unsaturated chamber, twice with chloroform or dichloromethane. Determination by absorbance measurement at 280 nm. Preparative layer chromatography on silica gel. A new device for isolation of sythesis products in sub-milligram amounts was successfully employed.
Acta Chrom. 12, 201-210 (2002). TLC of important organophosphorus, organochlorine, and pyrethroid pesticides (dichlorvos, endosulfan, malathion, monocrotophos, parathion, phorate, phosphamidon, quinalphos, dimethoate, anilofos, chlorpyrifos, fenvalerate, methyl oxydemeton, and methyl parathion) on stannic oxide–silica gel G layers with a variety of mixed aqueous and organic mobile phases. Detection by treatment with iodine vapor. For quantification corresponding zones were removed from the plate and etracted with ethanol. Quantitative determination by spectrophotomety with the molybdenum blue method. Monocrotophos, dimethoate, and malathion in soil samples were analyzed to test the applicability of the simple method.
