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. Chem. Pharm Res. 2(5), 92-96 (2010). TLC of ofloxacin and cefixime on silica gel with methanol - ethyl acetate - 25 % ammonia 7:7:3. The hRf value of ofloxacin was 61 and of cefixime 78. The method was linear in the range of 50-500 ng/band. The recovery was in the range of 99.3-102.2 %. Quantitative determination by densitometry in absorbance mode at 295 nm.
J. Planar Chromatogr. 25, 320-325 (2012). HPTLC of ursolic acid in the leaves of Diospyros melanoxylon on silica gel with chloroform - methanol 19:1. Detection by dipping in 5 % methanolic sulphuric acid reagent and heating at 105 °C for 3 min. Quantitative determination by absorbance measurement at 540 nm. Linearity was in the range of 50-450 ng/zone for ursolic acid. Limits of detection and quantification were found to be 20 and 40 ng/zone. Recovery (by standard addition) was 97.5 %.
and its selected derivatives studied by adsorption and partition thin-layer chromatography techniques
J. Planar Chromatogr. 29, 247-255 (2016). HPTLC of salicylic acid and their derivatives (acetylsalicylic acid, salicylanilide, salicylaldehyde, salicylamide, methyl salicylate, phenyl salicylate, 2,5-dihydroxybenzoic acid, salicylhydroxamic acid, 3,5-dinitrosalicylic acid, 3-aminosalicylic acid, 4-aminosalicylic acid, and 5-aminosalicylic acid) on silica gel with n-hexane – diethyl ether – 80 % acetic acid in various volume compositions (80:20:3, 60:20:3, 70:20:3, 80:10:3, 70:10:3, 60:10:3, 8:2:1, 7:2:1, 6:2:1, 8:2:2, and 8:2:3) and on RP-18, RP-8, and CN phase with methanol – water in various volume compositions (10:0, 9:1, 8:2, 7:3, 6:4, 5:5, 4:6, 3:7, 2:8). The best separation was obtained on RP-18W. Evaluation by cluster analysis (single linkage method, Euclidean distance).
(Chinese). (Determination of sorbic acid and benzoic acid in foods). TLC of sorbic acid and benzoic acid on polyacrylamide gel with butanol - NH3 - ethanol 7:1:2, or isopropanol - NH3 - ethanol 7:1:2. Detection by staining with 0.04 % bromocresol purple in ethanol. Sensitivity for both 3000 ng.
J. Chromatogr. 366, 396-4 02 (1986). TLC of 26 allo bile acids as their methyl esters on silica with hexane - ethyl acetate 83:17 and 3:2, and on C-18 silica with methanol - acetonitrile - water - formic acid 47.5:47.5:5:0.5 and 40:40:20:0.5. Also reversed-phase HPLC. The combined use of normal- phase and reversed-phase TLC appears helpful as a supplementary analysis to reversed- phase HPLC.
Chinese J. Med. Ind. 18, 361-362 (1987) (Yiyao Gongye). TLC on silica with hexane - ethyl acetate - acetic acid - methanol 75:400:12.5:12.5. Detection by spraying with 15% sulfuric acid - ammonium hydrogen sulfate and heating at 110 °C for 10 min. Quantification by densitometry at 285 nm. RSD 0.54 %.
Acta Chimica 125, 831-838 (1988). TLC on silica with benzene, benzene - ethyl acetate 25:1 or 10:1 or 5:1, ethyl acetate, ethyl acetate - chloroform 11:2. Detection under UV 254 nm.
J. Chromatogr. 475, 461-466 (1989). TLC of hydroxy fatty acids isolated from rat liver glycerophosphatides on silica with hexane - diethyl ether 1:1. Detection by spraying with methanol - sulfuric acid 1:1 and heating at 100°C.
