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. 3, 275-276 (1990). Evaluation of “useful” reagents for the detection of amino acids. TLC of 22 amino acids on silica with propanol - water 7:3. Detection by spraying with 0.2% solution of 1,3-indanedione in 0.1 M sodium hydroxide - ethanol 1:1 of 1% o-mercaptobenzoic acid in 1 M aqueous sodium hydroxide - ethanol 1:1. Detection limits 0.05 - 0.4 µg.
J. Planar Chromatogr. 5, 175-178 (1992). TLC and HPTLC of racemic dinitropyridyl, dinitrophenyl, and dinitrobenzoyl amino acids on RP-18 silica with 4% BSA in 0.1 M acetate buffer (pH 4.72) containing 2% 2-propanol. Visualization under UV 254 nm. The method is simple, highly sensitive, inexpensive, and the plates furnish excellent resolution of most of the DL racemates with development times between 1 and 2 hours. Enantiomeric resolution is highly dependent on mobile phase composition, the concentration of both BSA and organic modifier having a particularly marked influence on the resolution observed. Possible reasons for this behavior are formulated and discussed.
J. Liquid Chromatogr. 17, 2457-2468 (1994). TLC of histamine on silica with ethanol - NH3 8:2. Detection and identification by spraying with 1) a solution of 0.25 g PtCl6, 5 g KI, and diluting to 100 mL with water - hydrochloric acid 100:2; 2) a solution of 0.5 g ninhydrin in 100 mL acetone; 3) a solution of 12.5 mg fluorescamine in 100 mL acetone. Determination by HPLC.
Talanta 42, 1553-1557 (1995). TLC on RP-18 with methanol - water 1:1, 1:3, 1:5. Analysis of amino acids that form colored compounds with reagents such as ninhydrin by spectrophotometry.
J. Planar Chromatogr. 11, 365-369 (1998). OPLC of 11 cyanobacterial hepatotoxins (cyclic heptapeptides; e. g. MCYST-LR, -RR, -YR, -LA, NODL) on HPTLC silica gel with water - ethyl acetate 1-propanol 2:5:3. Densitometry at 240 nm (absorbance).
Food Additives Contam 17, 459-462 (2000). 2D-TLC of aflatoxin B1 on silica gel with ether - methanol - water 96:3:1 and acetone - chloroform 1:9. Detection under UV and quantification by standard comparison.
J. Planar Chromatogr. 17, 280-285 (2004). TLC of flavonoids (quercetin, I3,I8-biapigenin, quercitrin, isoquercitrin, hyperoside, rutin) and phenolic acids (caffeic and chlorogenic acid) on silica gel with ethyl acetate - formic acid - acetic acid - water 100:11:11:26 and ethyl acetate - formic acid - water 8:1:1. Detection by spraying with natural products - polyethylene glycol reagent and observation under UV light at 365 nm. Detection limit for flavonoids was 2.5 µg. Quantitative determination by spectrophotometry, calculated as quercetin. Also TLC of 16 amino acids on cellulose.
J. Planar Chromatogr. 21, 299-304 (2008). HPTLC of 21 amino acids on silica gel impregnated with 5 % Ag ion with borate phosphate buffer pH 2.3. After drying at 50 °C detection by spraying with ninhydrin. With this system separation of alanine, phenylalanine and tryptophane could be achieved, as well as separation of alanine, tyrosine and tryptophan. Separation of these amino acids was neither achieved on conventional silical gel (without Ag impregnation) nor by addtion of buffered 5 % silver nitrate solution (pH 2.3) to the mobile phase.
