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.
Acta Chimica 124, 541-545 (1987). TLC on silica with benzene - acetone 30:1. Detection by spraying with 50% phosphoric acid and heating at 110°C for 10 min.
I. Activated granulocyte induced lipid peroxidation in red blood cells. Acta Veterinaria, 39, 175-185 (1991). TLC of amines on cellulose with butanol - pyridine - acetic acid - water 3:3:1:1. Detection by spraying with ninhydrin reagent.
J. Chromatogr. B 667, 185-187 (1995). HPTLC on silica with 1) dichloromethane - triethylamine 4:1 for developing upto 30 mm; 2) dichloromethane - toluene - triethylamine 5:4:1 for developing upto 60 mm, c) toluene for developing upto 90 mm. Enhancement of the fluorescence by dipping the plate for 5 sec in paraffin - hexane 37:100. Quantification by fluoro densitometry at 310 nm. Discussion of the degradation of dansyl polyamines due to the time interval between application of samples.
Biochemical Systematics and Ecology 28, 209-216 (2000). TLC of guanidine derivatives on silica gel with butanol - pyridine - acetic acid - water 4:1:1:2 or propanol - acetic acid - water 4:1:1. Visualization with Sakaguchi reagent.
J. Planar Chromatogr. 18, 67-72 (2005). TLC of trans-resveratrol (trans-3,5-dihydroxystilbene), semicarbazide and dimedone (as standards) on silica gel using different mobile phases; OPLC on silica gel with chloroform - methanol 10:1. After drying bioautographic detection by immersion in the bacterial suspension of Pseudomonas savastanoi for 25 s. Visualization with MTT either after a short draining period or after overnight incubation.
Chem. Anal. (Warsaw) 54, 1-12 (2009). An HPTLC method has been developed for estimation of modafinil in tablet formulation and stability assessment. HPTLC on silica gel with toluene - chloroform - methanol 2:2:1. The hRf value of modafinil was 46. Densitometric evaluation at 220 nm. The method was linear in the range of 100-500 ng/band. The sample compound was well separated from all degradation products. The method was suitable for analysis and also for stability studies.
J. Planar Chromatogr. 24, 474-481 (2011). TLC of the active S-(+)-enantiomer escitalopram oxalate (ESC-OX), escitalopram cyanodiol, the R-enantiomer and escitalopram N-oxide impurities on silica gel (containing beta-cyclodextrin as chiral additive) with acetonitrile - 0.1 % acetic acid - water 10:1:6:2 with chamber saturation for 30 min. Using 3 mg urea per 100 cm2 of silica-coated plates as a chiral additive also achieves a good enantiomeric separation with acetonitrile - 1 % acetic acid - ethyl acetate - methanol - water 10:1:2:4:3. Detection at 254 nm. Quantitative determination by absorbance measurement of ESC-OX at 240 nm. The hRf values of ESC-OX, escitalopram cyanodiol, the R-enantiomer and escitalopram N-oxide were 75, 40, 31, and 23, respectively. The linearity was 0.25-10 mg/10 mL (r = 0.9991). Accuracy was 99.7 %. LOD and LOQ were 13 and 44 µg/mL for ESC-OX.
Anal. Biochem. 172, 484-487 (1988). HPTLC on silica with butyl acetate - ethyl acetate 5:1, chloroform - butyl acetate - ethyl acetate 3:3:1, chloroform - butyl acetate - ethyl acetate -triethylamine 12:2:4:1. Preservation of the chromatograms by dipping in 10% paraffin oil in cyclohexane and heating. Quantification by fluorodensitometry at 366/>400 nm. Detection limit, 1-4 p mol.
