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.
Planta med. 65, 311-315 (1999). TLC of O-acetylmacralstonine on silica gel with chloroform -methanol 14:1. Detection under UV.
Planta med. 66, 30-34 (2000). HPTLC and preparative TLC of 8 alkaloids (cryptolepinoic acid, methyl cryptolepinoate, ethyl cryptolepinoate, cryptolepine, hydroxycryptolepine, quindoline, cryptoheptine, cryptoquindoline) on silica gel with toluene - 2-propanol - NH3 50:50:3; chloroform - methanol - NH3 90:10:1; 80:20:3; 85:15:3; chloroform; chloroform - methanol 98:2; 19:1. Detection by densitometry at different wavelengths; and with Dragendorff and iodoplatinate spray reagent.
Planta med. 68, 770-775 (2002). Preparative and analytical TLC of chelirubine, sanguinarine, macarpine, and chelerythrine on silica gel and aluminium oxide with chloroform - methanol 49:1. Detection under UV light.
foliage. J. Planar Chromatogr. 17, 218-223 (2004). TLC of gamma-coniceine and coniin on silica gel with chloroform - ethanol 13:7. Detection and quantification by spraying with Dragendorff’s spray reagent and visual comparison of the intensity of the colour of the sample spots with that of the spots of the corresponding standards. Detection limits wered 1.7 and 0.7 µg per spot for coniine and gamma-coniceine, respectively.
Studied by Different Chromatographic Techniques. Chromatographia 63 (Supplement 13), S81 - S86 (2006). TLC of isoquinoline alkaloids (chelidonine, chelerythrine, sanguinarine, coptisine and berberine) in Chelidonium plant organs on silica gel with chloroform - methanol 2:1, and methylene chloride - methanol 97:3. Quantification by densitometry at UV 254 nm. Detection is very sensitive because of fluorescence of alkaloids without purification. Comparison with HPLC, showing that the TLC methodis the most simple, accurate, reproducible and convenient analytical technique for fast investigations and routine determination of Chelidonium alkaloids.
Anal. Chem. 79, 2778-2789 (2007). TLC of alkaloids (berberine chloride, palmatine chloride, hydrastine, tetrahydroberberine, hydrastinine hydrochloride and jatrorrhizine) on silica gel with ethyl acetate - methanol - formic acid - water 50:10:6:3. Detection under UV 254 nm. Detection levels were 5 ng/zone each or 14-28 pmol. Desorption electrospray ionization mass spectrometry was investigated as a means to qualitatively identify and to quantify analytes directly from developed normal-phase TLC plates.
J. Planar Chromatogr. 27, 2980-2988 (2014). HPTLC of piperine in commercial samples of pepper on silica gel with acetone - n-hexane 3:2. Quantitative determination by absorbance measurement at 360 nm. The hRF value for piperine was 90. The LODs and LOQs were 590 and 1800 ng/zone, respectively. Recoveries were between 98.1 and 99.2 %
Planta Medica 82 (15), 1368-1373 (2016). The incubation mixture of dihydroergotamine with rat liver microsomes was dissolved in methanol – chloroform – ethyl acetate 1:1:1. Preparative TLC on silica gel with methanol – chloroform 1:9. Two zones (hRF 21 and 35) corresponding to produced metabolites were scratched off the plate, separated from the silica with methanol – ethyl acetate 1:1 and, after purification on cyclodextrin, identified through LC-MS-MS and proton-NMR as 5-hydroxyl-dihydroergotamine and 11-hydroxyl-dihydroergotamine, respectively.
