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. 2, 321-322 (1989). TLC of atrazine on silica with toluene - acetone 85:15. Detection by absorbance at 224 nm; detection limit 20 ng/L water.
J. China Pharm. Univ. (Zhongguo Yaoke Daxue Xuebao 20, 184 (1989). TLC of silybin on silica with chloroform - acetone - formic acid 9:2:1. Quantification by fluoro densitometry at 335/>400 nm.
Optimization of mobile phase, detection and direct evaluation. J. Chromatogr. 502, 385-392 (1990). TLC of phospholipids on silica with a mixture of chloroform – methanol – water. Optimization of the mobile phase by using a mobile solvent composition triangle. Improvement of separation of phospholipids by using acetate buffer (pH 4) in the mobile phase instead of water and by impregnation of the silica layer with phosphoric acid. Detection by spraying with Dittmer-Lester reagent. Quantification by densitometry at 720 nm.
Chinese Anal. Chem. (Fenxi Huaxue) 18, 567-570 (1990). TLC of N-phenylphenothiazine and N-(a-pyridyl)-phenothiazine on silica with 1,2-dichloromethane – cyclohexane 1:4 and 1:1. Detection under UV. Identification by IR and NMR after elution. Quantification by densitometry at 260 nm and 246 nm, respectively. Detection limits 2 ng/spot and 5.3 ng/spot, respectively.
J. Pharm. Biomed. Anal. 8, 253-257 (1990). A densitometric method for determination of complex mixtures of conjugated oestrogens in raw material and tablets was developed. The proposed procedure comprised hydrolysis of sodium sulfate esters of oestrogens and oestradiol, equilenin, 17a-dihydroequilenin, the chloroform extraction of free oestrogens and methyltestosterone (internal standard). TLC on silica with chloroform - cyclohexane - dioxane - triethylamine 45:40:10:6. Quantification by densitometry at 254 and 280 nm. Detection limit 0.06 µg, recoveries 97,1% (conjugated oestrogens) and 103,2% (tablets). The proposed method is simple, rapid, and reproducible.
Proc. 6th Int. Symp. Instrum. Planar Chromatogr., (Interlaken 1991), Inst. Chromatogr., Bad Dürkheim, FRG, 97-102 (1991). HPTLC on silica with water - methanol - sodium acetate buffer (0.2M, aqueous) 28:12:60:10. Detection by dipping into Dragendorff’s reagent. Post chromatographic derivatization by heating. Quantitative determination after heating and fluorescence enhancing (dipping in light liquid paraffine - hexane 1:2 by scanning in fluorescence mode 313/>390 nm. Detection limit < 10 ng/zone.
Chinese J. Chromatogr. (Sepu) 9, 113-116 (1991). TLC on silica with isopropanol - acetic acid - water 14:1:5. Detection by dipping into a solution of potassium hydroxide in ethanol and heating at 160 °C for 10 min. Quantification of fluoro densitometry at 230 nm. Detection limit 40 ng. The calibration curve was linear over the range of 40 - 350 ng with the correlation coefficient of 0.998.
Proc. 6th Int. Symp. Instrum. Planar Chromatogr., (Interlaken 1991), Inst. Chromatogr., Bad Dürkheim, FRG, 19-22 (1991). TLC of metoprolol, propranolol and alprenolol on diol modifyed silica with dichloromethane containing N-carbobenzoxy glycyl-L-proline (ZGP). Scanning is performed by absorbance at 280 nm. To improve the reproducibility the plates were prewashed with dichloromethane and impregnated with water. It was important to keep the amount of water constant.
