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.
of Chromatogr. 2, 138-140 (1984). (Chinese). (A new method of the quantitative determination of proline and hydroxyproline.) TLC of proline and hydroxyproline on silica with butanol- acetic acid - water 4:1:1. Detection by multiple immersion in a) acidified acetone solution of ninhydrin-cadmium, b) a solution of 0.5 % isatin, followed by c) solution of 15 % sodium silicate. Sensitivity 100 ng. Densitometry at 510 nm.
Determination by using autoradio - layer chromatographic recorder.
J. Chromatogr. 391, 343-345 (1987). TLC of N-carbamyl-D, L-tryptophan on silica containing a chiral stationary phase, 2S, 4R, 2'RS-4-hydroxy-1- (2-hydroxydodecyl) proline, and copper(II) with water - methanol system at reduced temperature. Detection by spraying with Ehrlich's reagent and heating at 105 °C for 5 min Sensitivity, 100 mg/mL.
J. Chromatogr. 436, 341-343 (1988). TLC of various amino acids on silica with methanol - chloroform - 3:1. Detection by spraying the plates first with 0.01% fluorescein isothiocyanate in 0.1 M aq. sodium hydroxide solution. After heating at 90 °C for 10 min., the plates are cooled and then sprayed with 0.25 % ninhydrin in acetone. Various different colors are obtained. Detection limit 0.5-1.0 µg.
J. of Medicinal Chemistry 32, 174-179 (1989). TLC on silica with 1-butanol - acetic acid - pyridine - water 5:5:4:1, 2-propanol - 25% NH3 - water 3:1:1, ethyl acetate - pyridine - acetic acid - 5:5:1:3 and butanol - acetic acid - water 4:1:5. Visualization with ninhydrin, fluorescamine and iodine vapor.
Chinese J. Chromatogr. 7, 181-183 (1989). TLC of 11 amino acids on microcrystalline cellulose with butanol - acetic acid - water 4:1:1. Detection by spraying with 0.5% ninhydrin in acetone. Quantification by densitometry. Comparison with other methods. The results were in good agreement with those obtained with amino acid auto analyzer.
Anal. Chim. Acta 223, 411-418 (1989). Optimization of multicomponent mobile phase system in TLC by using an overall figure of merit (FOM) for separation, based on an equation which defines the extent of the separation of pairs of spots. Demonstration of the method in simplex optimization of separation of 17 amino acids by two-dimensional TLC on cellulose with tert butanol – 25% NH3 – MEK – water 12:6:1.52:2.48 for the first dimension, and butanol – acetone – acetic acid – water 10.29:6.82:5.06:3.65 for the second.
J. Planar Chromatogr. 3, 65-67 (1990). Description of a method for chromatographic separation of enantiomers involving chiral mobile phase additives. Amino acid derivatives and several alkaloids are separated by TLC on different types of RP plates using a mobile phase containing maltosyl-ß-cyclodextrin. Visualization under 254 nm UV. A comparison was made between octadecyl, diphenyl, and ethyl RP TLC plates.
