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.
( Chinese) - (TLC-densitometry of isoflavones in pueraria lobata.) TLC of daidzein, daidzin, puerarin and daidzein 4,7-diglucoside in the root of P. lobata and in tablets on silica with toluene - methanol -10 % formic acid 7:3:00.2, or ethyl acetate - methanol -50 % formic acid 8:2:0.2. Quantification by densitometry. Relative standard deviations: 1.51 % for puerarin, 1.61 % for daidzein.
V. Danube Symposium on Chromatography Yalta, November 11 -16, 1985. Samples of 100 ml urine acidified with acetic acid, urineporphyrins adsorbed on talcum. TLC of methylesters on silica. Densitometry by fluorescence.
(Comparative evaluation of analytical methods for the determination of preservatives. The determination of methyl-p-hydroxy-benzoate in the preparates of the pharmacopoeia by quantitative thin-layer chromatography and by gas-chromatography.) A simple, relatively rapid and repeatable thin-layer densitometric (and gas-chromatographic) method has been developed for quantitative determination of methyl-p-hydroxy-benzoate content of syrups, ointments and mucilages, corresponding to the requirements of the pharmacopoeia. Sample preparation with Extrelut columns. TLC on silica with pentane - ether 7:3. Detection by UV 254 nm. Detection limit 100 ng, densitometry by absorbance at 258 nm.
(Determination of paracetamol in serum by HPTLC.) Fresenius Z. Anal. Chem. 321, 601-602 (1985). Chromatography on silica with hexane - acetone - ethanol 6:3:1. Densitometry by absorbance at 250 nm. Determination limit 250 ng/ml serum.
International Lab. 16, (5) 74-77 (1986). TLC of thebaine on silica with chloroform - methanol 9:1. Quantification by densitometry at 280 nm.
Improvement and evaluation of a method using molybdenum blue reagent for detection. J. Chromatogr. 375, 255-266 (1986). TLC of phospholipids on silica with chloroform - methanol - water 65:25:4, and chloroform - acetone - methanol - acetic acid - water 50:20:15:10:5. Detection by spraying, with molybdenum blue reagent. Quantification by densitometry at 700 nm. Derivatization also by spraying with 3 % copper acetate solution in 8 % aqueous phosphoric acid and heating at 140 °C for 20 min. Densitometry at 450 nm.
Detection by exposing to iodine vapor. Quantification by densitometry at 290 nm.
(TLC chromatographic analysis for the quantitative estimation of the fecal bile acid composition). TLC of cholic acid, chenodesoxy cholic acid, desoxy cholic acid, lithocholic acid and ursodesoxy cholic acid on silica with isooctane - isopropanol - acetic acid 30:10:1 and/or isooctane - ethyl acetate - acetic acid 10:10:2. Derivatization with 2 % ethanolic solution of 2,7-dichlorofluoresceine. Densitometric quantification by fluorescence. Fiber rich polysaccharides (dietary fibers) elevate fecal bile acids and their metabolites. The possible role of this diet in relation to fecal bile acid concentration and large bowel cancer is discussed.
