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. The saved items can be printed to PDF using the print function of your web browser.
J. Planar Chromatogr. 20, 91-94 (2007). Descripton of the modeling of TLC separation of androstane isomers to find the optimum mobile phase. A mathematical model was developed and tested. The model takes into account the interaction between solvents and uses a complex function for modeling. The proposed mathematical model gives results similar to those obtained by use of other optimization models, e. g. the Simplex and Prisma methods. TLC of 5alpha-androstan-3beta-ol, 5alpha-androstan-3alpha-ol, 5alpha-androstan-17beta-ol, 5beta-androstan-3alpha,17beta-diol, 5alpha-androstan-3beta,17beta-diol on silica gel in a saturated chamber using different mixtures of chloroform, acetone, and petroleum ether resulting in an optimum mobile phase composition of 55:19:26. Detection by spraying with 5 % ammonium molybdate and 5 % sulfuric acid in water and heating to 80 °C.
Hungarian Scientific Instruments 62, 1-9 (1986). Separation of amino acids and S-containing amino acids on cellulose with MEK -acetonitrile - acetic acid - water 3:4:1:2. Separation of N-methylated and N-formylated L-lysine on silica with propanol - methanol - 0.1 M aqueous Na-acetate 20:3:30, Separation of ether soluble DN amino acids on silica with chloroform - carbon tetrachloride -MEK - propanol - methanol - acetic acid 30:30:20:30:15:2. Separation of corticosteroids with acetonitrile - butyl acetate 1:1 and of trigonelline from tomato juice with propanol - methanol - 0.1 M Na-acetate. Appropriate staining reagents; densitometry by absorbance.
J. Gaoxiong Med. Sci. (Gaoxiong Yixue Kexue Zazhi) 7, 545-549 (1991). TLC of 8 glucocorticoids on silica with chloroform - dioxane - methanol 15:4:1. Detection by derivatization with (1S)-(-)-camphanic chloride using triethylamine as a catalyst.
Asian J. Chem. 20(7), 5514-5518 (2008). HPTLC of dutasteride on silica gel with toluene - ethyl acetate - acetic acid 14:6:1. Absorbance measurement at 210 nm. The method was linear in the range of 50-500 µg/µL. Recovery was 99.3-99.5 %. The method was suitable for routine quality control.
J.A.O.A.C. 71, 226 (1988). TLC of coprostanol on silica with ether - heptane 55:45 after equilibration. Before sample application, plate is immersed in 5 % phosphomolybdic acid in ethanol and air dried. After chromatography, heating for 20 min at 120 °C.
J. Planar Chromatogr. 5, 139-140 (1992). HPTLC of bile acids (glyco-, tauro-, glycodeoxy-, taurodeoxy-, glycochenodeoxy-, taurochenodeoxycholic acid) on silica with A) chloroform - isopropanol - isobutanol - acetic acid - water 30:20:10:2:1 and 300:200:100:10:7, B) chloroform - propanol - isopropanol - acetic acid - water 30:20:10:2:1 both separately and in combination. Detection by dipping for exactly 5 s into 3.5% ethanolic phosphomolybdic acid and heating for 10 min at 70-80 °C. Quantification by densitometry at 625 nm.
60th Indian Pharmaceutical Congress PA-197, (2008) HPTLC of medroxyprogestrone acetate in bulk and injectable dosage form on silica gel with toluene - ethyl acetate - ammonia 800:200:1. Quantitative determination by absorbance measurement at 240 nm. The linearity was in the range of 50-1800 ng/spot. Recovery was 100.1 %. In the stability test (acid, base, peroxide, thermal, photodegradation) the compound was well separated from degradation products. The method was suitable for routine quality control and for monitoring stability.
Advances in Liquid Chromatography, Sept., 3-6 (1988), Szeged, Hungary. TLC of testosterone, 5-dehydroandrosterone and androsterone on cyano- and amino- modified precoated silica with hexane - acetone 80:20.
