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.
Biochemical Systematics and Ecology 13, 169-1 70 (1985). Analytical and preparative TLC on silica developed five times in chloroform - methanol 9:1 or six times in chloroform - methanol 85:15 in a chamber saturated with NH3; authentic samples of aristolochic acids were used as standards.
Determination by densitometry at 270, 240 and 245 nm for the three substances. Rel. standard deviation in the range 0.8-1.7 %.
Detection by spraying with 10 % sulfuric acid and heating at 110 °C for 7 min. Quantification by densitometry at 520 nm.
Chinese J. Pharm.Anal. 7, 338-340 (1987) (Yaowu Fenxi Zazhi). TLC on silica with ethyl acetate - petrol ether - acetic acid 8:2:0.3. Quantification by densitometry at 210 nm. Comparison of the results with those from other methods.
(Procyanidine and flavonoid contents of Crataegus drugs in dependency on origin, harvest-time and method of drying.) Herba Hungarica 26, 15-34 (1987). TLC on silica with ethyl acetate - methanol - water 20:7:3 for the oligomeric procyanidines and ethyl acetate - methanol - water 20:5:3 for the polymeric procyanidines. Detection with 1 g vanillin in 100 g 50 % phosphoric acid, heating at 110 °C for 10 min. Identification of the procyanidines under visible light as red spots.
J. Planar Chromatogr. 1, 261-264 (1988). Preparative OPLC of 5 furocoumarins on silica with n-hexane. Discussion of the influence of solvent strength, flow rate, separation distance, particle size and sample application on the separation.
Chinese J. Pharm. Anal. 8, 154-157 (1988) (Yaowu Fenxi Zazhi). TLC on silica with a) benzene - hexane - methanol 7:2:1, or b) methyl chloride - hexane - methanol 50:1:1. Detection under UV 254 nm. Quantification by densitometry at 270 nm.
J. Chinese Herb Med. (Zhongcaoyao) 20, 6-8 (1989). TLC of coumarins and essential oils on silica with cyclohexane - ethyl acetate - chloroform 5:3:1 and petrol ether - ethyl acetate 85:15, respectively. Detection under UV 366 nm. or/and spraying with 1% vanillin in sulfuric acid. Quantification by fluorodensitometry at 366/>400 nm for coumarins. The calibration curve was found linear over a range of 0. 47 - 2. 25 ng, CV = 1. 1% and recovery ~100%. Also GC method for essential oils.
