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. High Resol. Chrom. 11, 810-814 (1988). Identification problems encountered in HPLC/FTIR can be circumvented through use of a TLC plate as depositon and IR sampling medium showing increased resolution of components of complex mixtures.
Quaternary protoberberine alkaloids in plant material. J. Chromatogr. 291, 389-391 (1984). Circular TLC of quaternary alkaloids from jatrorrhiza palmata on silica with isopropanol - 1 M ammonium carbonate-dioxane 15:5:1. Detection by UV 254 nm. Also PLC. Solvent system suitable for other protoberberine-type alkaloids. Recommended method for protoberberine alkaloid separation.
Chromatographia 27, 123-127 (1989). Study of overloaded systems using an equilibrium sandwich for continuous TLC with dyes as model samples. Investigation of the effect of sample volume and the mode of development on the maximum separation yield. Calculation of the final Rf values for the front and rear edges of the bands with a computer program. Good agreement between the experimental Rf values of zone boundaries and the values predicted by computer simulation.
Anal. Chim. Acta 566 (2), 157-166 (2006). Extraction of pyrrolizidine alkaloids from the alkalised crude extract of Symphytum cordatum (L.) W.K. roots as free tertiary bases and polar N-oxides by one-step liquid–liquid partitioning and pre-fractionation by preparative multiple-development TLC on silica gel with chloroform – methanol – 25 % ammonia 50:5:1. Three alkaloid fractions of different polarities were obtained which showed different retention on silica gel: the most polar N-oxides had the highest retention, the tertiary bases had medium retention, and diesterified N-oxides had the lowest retention. Purification of the former fraction, which was reduced into free bases by sodium hydrosulfite, by liquid-liquid partitioning on Extrelut-NT3 cartridge. Further analysis by HPLC – ion-trap MS.
Planta Medica 83(14/15), 1200-1206 (2017). The fractionation on cyclodextrane with methanol of the butanol-soluble parts of a methanolic macerate of Gymnocarpos decander aerial parts was monitored by TLC on silica gel with n-butanol – acetic acid – water 12:3:5. Detection by derivatization with cerium sulfate–sulfuric acid reagent. Through further analysis of the 5 resulting fractions, roseoside and heterosides of quercetin, of isorhamnetin and of tetrahydroxyoleanene were detected._x000D_

Study of the factors affecting the transfer efficiency and the parent peak ratio. Limit of detection, in the low nanogram range.
niger and Hygrophila megalantha by TLC.) (Chinese). Chinese J. Pharm. Anal. (Yaowu Fenxi Zazhi) 16, 119-122 (1996). TLC on silica with ethyl acetate - formic acid - NH3 17:2:1.
