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. of Natural Products 52, 810-817 (1989). TLC of loline and norloline on silanized silica with 0.5% triethylamine in methanol. Detection by spraying with potassium iodoplatinate reagent.
Chromatographia 28, 516-518 (1989). TLC of 10 tropolone alkaloids on silica with 1) benzene - ethyl acetate - diethylamine - methanol - water 15:12:3:6:1, 2) benzene - ethyl acetate - diethylamine 5:4:1 + 8% methanol. Quantification by fluorodensitometry. The method can be used for identification and quantification of alkaloids in biological materials.
Merck Spectrum 1990, 34-37. HPTLC of dansyl morphine and dansyl monoacetylmorphine on silica with methanol – NH3 25 % 99:1. Detection after drying in cold air for 20 sec, dipping in paraffin – hexane solution for 2 sec, drying in cold air and viewing under UV 366 nm. Quantification by fluorimetry.
ebeiensis G.G. Yu et G.Q. Ji by thin-layer chromatography.) (Chinese). J. Chinese Herb Med. (Zhongcaoyao) 22, 477 (1991). TLC of peimine, peiminine and eibeinine on silica with cyclo-hexane - ethyl acetate - diethylamine 6:4:1. Detection by spraying with potassium iodobismuthate reagent. Quantification by densitometry at 495 nm.
J. Planar Chromatogr. 5, 28-34 (1992). HPTLC and TLC of 17 cinchona alkaloids on silica with chloroform – acetone – methanol – 25% aqueous NH3 60:20:20:1 (optimum mobile phase). The most sensitive quantitative measurements were fluorescence detection after post-chromatographic derivatization with 10% sulfuric acid solution. Detection limit 0.5 - 0.7 ng/spot. Also two-dimensional TLC.
Phytochemistry 32, 1591-1594 (1993). TLC of various cyclopeptide alkaloids on silica with chloroform - methanol 93:7 and 19:1. Detection with Dragendorff’s reagent. Isolation of two new alkaloids from root bark by centrifugal TLC on silica with chloroform - methanol 49:1 and 19:1.
J. Planar Chromatogr. 6, 220-222 (1993). OPLC of i.a. berberine, chelidonine, sanguinarine, palmatine, hydrastinine, hydrastine, ajmaline, serpentine on silica with ethyl acetate - tetrahydrofuran - acetic acid 6:2:2. Detection under UV 365 nm and after immersion in Dragendorff's reagent. Quantification by spectrodensitometry at 540 nm (absorbance).
J. Chromatogr. 668, 427-433 (1994). Description of a sample preparation technique rendering alkaloid fractions suitable for TLC or GC determination of toxic pyrrolizidine alkaloids from various plant sources. The procedure includes the reduction of the alkaloid N-oxides with the oxygen-absorbing resin and a clean-up with strong cation exchange solid phase columns, as well as an enrichment of the alkaloids if desired.
