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. 20, 153-158 (2007). TLC of U(VI), Th(IV), lanthanides(III), Co(II), Ni(II), and Cu(II) on silica gel with di(n-butyl) and di(iso-butyl)dithiophosphoric acid as complexing agents in different organic solvents (polar and nonpolar). Visualization with 0.05 % arsenazo III for U(VI), Th(IV), and lanthanides(III), and with 0.1 % rubeanic acid in ethanol for Co(II), Ni(II), and Cu(II). Densitometric evaluation at 505 nm for Cu(II) and Co(II) and at 600 nm for Th(IV), U(VI), and Ni(II).
J. Planar Chromatogr. 21, 83-88 (2008). TLC of (+)-catechin and (-)-epicatechin on silica gel with diisopropyl ether - formic acid 9:1 in an unsaturated twin-trough chamber. Detection by spraying with vanillin-sulfuric acid reagent followed by heating at 120 °C for 5 min. Quantitative determination by absorbance measurement at 490 nm.
Pharmazie 63, 405-407 (2008). TLC of (+)-haemanthamine on silica gel or on RP-18. Detection by spraying with Dragendorff reagent or with 1 % cerium sulfate - sulfuric acid, followed by heating.
Pharmazie 63, 659-662 (2008). HPTLC and TLC of 1’-acetoxychavicol acetate on silica gel and RP-18. Detection under UV 254 and 365 nm, and after spraying with 1 % cerium sulfate/10 % sulfuric acid, and anisaldehyde reagent (5 mL acetic acid, 25 mL concentrated sulfuric acid, 425 mL ethanol, and 25 mL water).
J. Chromatogr. Sci. 46 (4), 298-303 (2008). HPTLC of three surfactants, cetyltrimethylammonium bromide (CTAB), dodecyltrimethylammonium bromide (DTAB), and polyoxyethylene (20) sorbitan monolaurate (Tween 20), on silica gel with 5 % aqueous thiourea - acetone - methanol 3:1:1. Evaluation of the effect of the carbon chain length of alcohols (methanol, ethanol, n-propanol, and n-butanol) on the mobility of these surfactants. The comparative study was performed with sulfur- (thiourea) and oxygen- (urea) containing compounds in the eluent. Investigation of the interference on the resolution of the mixture of CTAB, DTAB, and Tween 20, due to presence of metal cations as impurities.
J. Liq. Chromatogr. Relat. Technol. 31, 1492-1510 (2008). TLC of stearic acid, stearyl alcohol, and methyl stearate on silica gel (prewashed with methanol) with methanol - chloroform 1:1 followed by drying for 24 h at room temperature. Six new derivatization reagents were evaluated: gentian violet, methylene violet, methylene blue, methyl green, malachite green, and Janus blue. Detection by dipping for 5 s, followed by drying for 24 h at room temperature. Quantitative determination by absorbance measurement. The results obtained indicate that all of the new derivatization reagents give better results than the universally applied Rhodamine B. The best reagents for quantitative determination of stearic acid are methylene blue and Janus blue, for stearyl alcohol malachite green and Janus blue, and for methyl stearate methylene blue, Janus blue, and malachite green.
J. Liq. Chromatogr. Relat. Technol. 31, 1977-1985 (2008). TLC of vitamin B 12 and dicyanocobinamide on silica gel with 2-propanol - 28 % ammonia - water 7:1:2 in the dark at room temperature. After drying the plate was overlaid with 1.5 % agar containing a basal medium and a small volume of E. coli 215 culture, and then incubated at 30 °C for about 20 h. After spraying with a methanolic solution of 4 % 2,3,5-triphenyltetrazolium salt the plate was heated at 30 °C for 1 h. The method was applied to detect vitamin B12 or inactive corrinoids in foods.
J. AOAC Int. 91, 1145-1148 (2008). TLC of alpha-mangostin on silica gel with dichloromethane - methanol 24:1 in a saturated twin-trough chamber. Quantitative determination by absorbance measurement at 320 nm.
