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.
Polish J. of Pharmacology and Pharmacy 41, 97-102 (1989). TLC on silica with butanol - acetic acid - water 4:1:5 (upper phase), butanol - acetic acid - water - pyridine 15:3:3:10, chloroform methanol 7:3. Visualization with ninhydrin or iodine vapor.
Phytochemistry 28, 673-675 (1989). TLC identification of a new type of higher plant alkaloids, 3-hydroxy-11-norcytisine. TLC of dansylated alkaloids on silica with cyclohexane - ethyl acetate 2:3, benzene - diisopropylamine 5:1, chloroform - butanol - water 5:3:1, chloroform - diisopropylamine 8:3, chloroform - benzene - diisopropylamine 3:2:1. Visualization under UV 366 nm.
MSZ(Hungarian Norm) 14880, 3 (1989). TLC of 2,4, DNPH of ascorbic and dehydroascorbic acids on silica with ethyl acetate - chloroform - acetic acid 10:12:1. Quantification by densitometry (absorbance) at 500 nm. Detection limit 20 mg/L of vitamin C.
J.A.O.A.C. 71, 949-953 (1988). TLC of ochrotoxin A on RP18 with methanol - water (adjusted to pH 2.1 with phosphorus acid) 70:30. Detection under UV 366 nm. Quantification after scraping of spots and elution.
J. Chromatogr. 490, 236-242 (1989). HPTLC of benzoylecgonine on silica with ethyl acetate - methanol - dichloromethane - NH3 3:3:1:0.6. Detection by spraying with Ludy Tenger’s reagent and 20% sulfuric acid.
J. Planar Chromatogr. 2, 383-386 (1989). TLC separation of dyes and plant pigments on different modified silica stationary phases (cyclic diols, cyanopropyl, carboxylic ester) with toluene, isooctane - methanol - diethylether 7:1:2 as mobile phase and three methods of development - traditional vertical tank, experimental horizontal sandwich apparatus and an experimental over-pressure device. - The variation of the stationary phase can be used to gain selectivity advantages in chromatographic separations.
J. Planar Chromatogr. 2, 33-38 (1989). Two-dimensional TLC of anabolics on silica with 5 different solvent systems. Reference mixtures contained 2 - 20 ng of the steroids (zeranol, zearalenone, a-nortestosterone, medroxyprogesterone acetate, trenbolone, trebolone acetate). Alternatively a „4x4“ developing mode could be used. In this mode 4 samples are developed in two dimensions on one HPTLC plate. For inducing fluorescence reaction, the plates were dipped into a 5% sulfuric acid - ethanol solution for 30 s and then incubated at 95°C for 10 min. The fluorescence before and after heating was observed under UV 366 nm. The described method permit the routine detection of various anabolic residues in bovine urine at levels of 0.5 - 10 ppb. The recoveries are high (70 - 90%). Standard deviation were between 2 and 8%.
I. Blank pearl - identification and chromatographic determination of some undeclared medicinal ingredients. J. Chromatogr. 469, 406-411 (1989). TLC of indomethacin, mefenamic acid, diazepam and hydrochlorothiazide on silica with ethyl acetate and ethyl acetate - methanol 4:1. Detection under UV. Comparison with HPLC. Method suitable for quality control of drugs.
