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.
Proc. 9th Internat. Symp. Instr. Chromatogr., Interlaken, April 9.-11., 203-212 (1997). Review of planar chromatography in research of medicinal plants demonstrating the importance of the technique for extraction, purification, isolation, quantitative determination, and biological screening. Specially mentioned is the characterization of solvents due to its central role in selection of extraction solvents, mobile phase optimization, transfer of optimized mobile phase between the different chromatographic techniques, as well as identification procedure. Application of classical planar chromatography and FFPC (forced flow planar chromatography).
J. Planar Chromatogr. 10, 380-384 (1997). TLC of plant extracts (i.a. saponins, flavonoids, terpenes, triterpenes) on silica with ethyl acetate - acetic acid - water in different ratios , n-butanol - acetic acid - water 5:1:4 (upper phase) and chloroform - methanol - water 32:25:5. Quantification by densitometry at 254 nm. Mobile phase optimization was performed by the PRISMA model, based on the choice of three different solvents from three different groups of the Snyder classification; the flexible simplex method was used to find the optimum eluent composition.
Indian Drugs 35 (5), 266-268 (1998). HPTLC on silica gel with ethyl acetate - methanol - water 200:27:20. Densitometry at 260 nm.
J. Chin. Trad. Med. (Zhongguo Zhongyao Zazhi) 29, 308-310 (1998). TLC on silica gel with chloroform - methanol -water 14:8:1. Detection by spraying with 10% sulfuric acid in ethanol and under UV 365 nm. Quantitation of catalpol by densitometry at 340 nm. Discussion of the relationship between the content of catalpol and the extracting conditions. Precision 2.19% (n=5) within plate, 2.50 (n=5) plate-to-plate. Recovery 96.1 ± 2.1% (n=3).
Acta Pharmaceutica Hungarica 68, 183-188 (1998). TLC of plant extracts on silica with toluene - ethyl acetate - formic acid 5:4:1. Densitometry.
J. Planar Chromatogr. 13, 57-59 (2000). HPTLC of kaempferol and quercetin on silica gel with toluene - acetone - methanol - formic acid 46:8:5:1. After drying under nitrogen and heating at 40°C for 5 min densitometry at 254 nm. RSD 1.37 and 1.40 for kaempferol and quercetin respectively.
J. Chinese Trad. Patent Med. (Zhongchengyao) 22 (7), 476-477 (2000). TLC on silica gel with cyclohexane - acetone - benzene - ether 7:3:1:1. Detection by spraying with an improved reagent of potassium iodobismuthate first, and then with 25% ethanol. Quantitation by densitometry at 508 nm.
Chinese J. Chromatogr. (Sepu) 18 (6), 546-549 (2001). Presentation of a computer-assisted method for the optimization of mobile phase for the separation of mixtures of ginsenosides by 2D-TLC, based on the correlation between the proportions of solvent components and the Rf values of ginsenosides, and using Dmin as selection criterion with a two factor Xs and Ys) statistically scanning technique. Discussion of the greater separation power and the excellent agreement of the results with the predicted ones.
