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. 6, 382-385 (1993). Investigation of the system silica gel and aqueous buffer - methanol eluent for the chromatography of alkaloids. TLC of quaternary alkaloids on silica buffered at different pH and eluted with mobile phases of pH similar to that of the silica. Detection under UV at 366 nm of with Dragendorff's reagent. Quantification by scanning in absorbance at 280 nm. Quaternary alkaloids: sanguinarine, chelerithrine, chelilutine, chelirubine, dihydrosanguinarine, dihydrochelerithrine, berberine.
J. of Natural Products 57, 665-669 (1994). TLC of alkaloids in crude plant extracts on silica with petrol ether - acetone 2:1, dichloromethane - methanol 95:5 and hexane - acetone 1:1. Detection by spraying with Dragendorff's reagent. Excellent separation of closely related alkaloids.
J. Chinese Herb. Med. 26, 463-464 (1995). TLC on silica with chloroform - methanol - NH3 100:8:1. Detection by spraying with 0.5% ninhydrin in ethanol. Quantification of ephedrine by densitometry at 510 nm.
Biochemical Systematics and Ecology 24, 415-421 (1996). TLC of 3'-acetylheliosupine, heliosupine, viritiflorine, heliosupine N-oxide on silica with dichloromethane - methanol - NH3 85:15:2 or 75:23:2.
Norditerpenoid alkaloid analysis by electrospray mass spectrometry. Biochemical Systematics and Ecology 25, 279-285 (1997). TLC of alkaloids on silica with chloroform - methanol 9:1. Detection by spraying with Dragendorff's or iodoplatinate reagent.
J. Agric. Food Chem. 46, 2096-2101 (1998). TLC of a-tomatine and hydrolysis products (i.a. tomatidine) on silica gel with chloroform - methanol - 1% NH3 2:2:1, bottom layer, chloroform - methanol - 2% NH3 14:6:1, and chloroform - methanol - 1% NH3 13:7:1; 5:5:1. Visualization by spraying with anisaldehyde solution followed by heating at 120°C for 5 min.
J. Planar Chromatogr. 13, 457-462 (2000). TLC and HPTLC of extracts and standards (quinine, quinidine, cinchonine, cinchonidine) on silica gel with 7 different mobile phases. The quaternary mobile phase toluene - chloroform - diethyl ether - diethylamine 8:3:7:2 enabled the determination of alkaloids in a variety of preparations and extracts. Two different modes of densitometric evaluation (absorbance and fluorescence) were used. Results from quantitative analysis were statistically assessed by use of a calibration procedure, a calibration equation, the correlation coefficient, and the relative standard deviation.
J. Planar Chromatogr. 14, 364-370 (2001). TLC of 24 alkaloids (aconitine - yohimbine) on silica gel and aminopropyl-modified silica gel plates as well as on cyanopropyl-, diol- and RP 18-modified silica gel plates using a variety of binary mobile phases prepared from n-hexane and polar modifiers - 2-propanol, ethyl acetate, methyl ethyl ketone, tetrahydrofuran, dioxane - in different concentrations for NP chromatography and reversed-phase systems with buffered aqueous -acetonitrile mobile phases (pH 9.15). Visualization at 254 nm.
