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.
Chromatographia 63 (3-4), 209-213 (2006). HPTLC of valerenic acid in Valeriana jatamansi and Valeriana officinalis on silica gel with hexane - ethyl acetate - acetic acid 160:40:1. Detection with anisaldehyde-sulphuric acid reagent. Quantitative determination by absorbance measurement at 700 nm. The calibration curves were linear in the range of 500 ng - 2.5 µg/zone.
J. Chromatogr. 267, 109-116 (1983). TLC of opiates (morphine, codeine, quinine, methadone and nor-propoxyphene) and polydrugs on silica with different solvent systems, e. g. a) ethyl acetate - cyclohexane - methanol - water 70:15:2:8:0.5, b) ethyl acetate - cyclohexane - methanol - NH3 56:40:0.8:0.4, c) ethyl acetate - cyclohexane - methanol - NH3 70:15:2:8:0.5, d) ethyl acetate - cyclohexane - NH3 50:40:0.1, acc. to Kaistha, Jaffe et al. Detection reagents which were used: a) silver-acetate 1 % in water, b) mercuric sulfate solution, c) diphenylcarbazone 0.01 % in acetone / water, d) 0.5 % sulfuric acid, e) iodoplatinate, f) iodine-potassium iodide reagent, all acc. to Kaistha, Jaffe et al., J. Pharm. Sci. 61, 679 (1972).
Phytochem. Anal. 17, 394-397 (2006). HPTLC of phyllanthin and hypophyllanthin from Phyllantus species, e.g. Phyllantus amarus, on silica gel with hexane – acetone – ethyl acetate 37:6:4. Detection by spraying with vanillin in concentrated sulfuric acid and ethanol. Quantitative determination by absorbance measurement at 580 nm. Recovery of phyllanthin is 98.7 % and of hypophyllanthin 97.3 %.The method was validated and the peak purities and limits of detection and quantification were determined.
J. Liquid Chromatogr. 6, 2661-2664 (1983). TLC of 1-(2,4-dinitrophenyl)-3,5-dimethyl/diphenyl-4-aryl azopyrazoles on silica impregnated with 1 % aromatic amine (e.g. p-toluidine) with a) xylene - chloroform - acetone 6:3:1, b) benzene - chloroform - ethyl methyl ketone 55:40:5: Detection limit 1-2 mg.
Pharmazie 61, 641-644 (2006). Preparative TLC of two novel acylated flavonol glycosides and three glycosides (structurally belonging to the group of 4-phenylcoumarins) on silica gel with formic acid - water - ethyl acetate 9:9:82. Detection by spraying with 1 % methanolic solution of diphenylboric acid 2-aminoethylester (natural products reagent), followed by drying. Evaluation under UV 366 nm.
J. Liq. Chromatogr. Relat. Technol. 29, 815-827 (2006). TLC of barbinervic acid, rotungenic acid, 24-hydroxy ursolic acid, and ursolic acid on silica gel with n-hexane - acetone - ethyl acetate 4:2:1. Detection under UV light.
J. Planar Chromatogr. 2, 395-397 (1989). Two-dimensional HPTLC of 22 sulfonamides on silica, silica C-18 and silica CN with 7 different mobile phases. Best results were obtained by using two completely different complementary systems, i.e. with a different separation mechanism.
