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

J. AOAC Int. 91, 1210-1217 (2008). HPTLC of monocrotophos, quinalphos, triazophos, parathion-methyl, isophenphos-methyl, temephos, parathion, phoxim, and chlorpyrifos on silica gel with automated multiple development. HPTLC of phoxim and chlorpyrifos on silica gel with dichloromethane - hexane 1:1 in a twin-trough chamber. Quantitative determination by absorbance measurement at 254 nm.
Anal. Chem. 79, 2778-2789 (2007). TLC of alkaloids (berberine chloride, palmatine chloride, hydrastine, tetrahydroberberine, hydrastinine hydrochloride and jatrorrhizine) on silica gel with ethyl acetate - methanol - formic acid - water 50:10:6:3. Detection under UV 254 nm. Detection levels were 5 ng/zone each or 14-28 pmol. Desorption electrospray ionization mass spectrometry was investigated as a means to qualitatively identify and to quantify analytes directly from developed normal-phase TLC plates.
Acta Chromatographica 20 (4), 637-642 (2008). TLC of thiamine hydrochloride from riboflavin, nicotinic acid, calcium D-pantothenate, pyridoxine hydrochloride, cyanocobalamin, and ascorbic acid on silica gel with dioxane - water 1:1. Detection under UV light. Examination of the effect of impurities (metal cations and inorganic anions) on the chromatography of thiamine hydrochloride. The detection limit for thiamine hydrochloride was 90 ng/spot and %RSD of thiamine hydrochloride was 14.9 % (n=5).
J. Planar Chromatogr. 23, 225-226 (2010). OPLC of oregano oil components (carvacrol, thymol, and linalool) on silica gel with dichloromethane. Detection under UV 254 nm, by spraying with vanillin-sulfuric acid reagent (0.1 g vanillin, 100 mL ethanol, and 2.2 mL 95-98 % sulfuric acid) and heating at 110 °C for 3 min, and in the BioArena system (the dried developed plates were dipped for 10 s into an aqueous cell suspension of the soil bacteria Bacillus subtilis and incubated for 2 h at 100 % rel. humidity and 30 °C). Visualizion of antimicrobial compounds was performed by immersing the plates for 5 s in an aqueous solution of MTT reagent (80 mg MTT and 100 mg Triton X-100 in 100 mL water). The layers were further incubated and and documented.
Microbiol. Res. 166, 255-267 (2011). TLC of lipopeptides (produced by Pseudomonas species in cultures of Pleurotus ostreatus; Pseudomonas reactans was used as a reference) on silica gel with chloroform – methanol – ammonia 80:25:4. Detection by spraying with 0.1 % bromothymol blue in ethanol, followed by heating.
J. Planar Chromatogr. 24, 57-59 (2011). HPTLC of piperine on silica gel with toluene - ethyl acetate - diethyl ether 6:3:1 in a saturated twin trough chamber. The hRf of piperine was 40. Quantitative determination by densitometry at 337 nm. Linearity was between 15 and 75 ng/zone. LOD and LOQ was 5 and 15 ng/zone, respectively. The recovery was 94.5 %. The instrumental precision, repeatability, intra-day and inter-day precision (%RSD, n = 6) was 0.6 %, 0.8 %, 0.9 and 0.8 %, respectively.
J. Planar Chromatogr. 25, 534-541 (2012). TLC of anthocyanins and anthocyanidins in berry fruits on cellulose layers with hydrochloric acid - glacial acetic acid - water 10:1:3. Quantitative determination by absorbance measurement at 520 nm. The hRf values obtained for pelargonidin and cyanidin were 78 and 58, respectively. The TLC method was complementary to an HPLC method and allowed for identification of the major anthocyanidins characteristic for each berry fruit.
Food Chemistry. 139, 866-871 (2013). HPTLC of catechin (1), proanthocyanidin (PAC) A2 (2) and PAC-B1 (3) in American cranberry (Vaccinium macrocarpon) extracts on silica gel with dichloromethane - ethyl acetate - formic acid 6:10:1. Detection by dipping into a hydrochloric solution of 1 % (w/v) vanillin, followed by heating at 110 °C for 2 min. Quantitative determination by absorbance measurement at 254 and 366 nm. The hRf values of (1), (2) and (3) were 63, 48 and 25, respectively. Linearity was in the range of 0.6-5 µg/band. Intermediate precision was below 2.1 %. Average recoveries (by standard addition) were 98.4 % for (1), 99.6 % for (2) and 98.5 % for (3).
