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.
J. Chromatogr. 439, 441-444 (1988). Two-dimensional TLC of 37 steroid hormones and metabolites on silica with dichloromethane - methanol - water 225:15:1.5 for the first direction and petrol ether (37-55°C) - ether - acetic acid 48:50:2 for the second. Detection under UV or by spraying with antimony trichloride and heating at 130°C for 5-10 min.
J. Chromatogr. 571, 73-86 (1991). Description of a digital autoradiographic TLC method for the separation of eight major androgens derived from testosterone metabolism. Direct quantification by radioscanning, using external standardization of plate by calibrated amounts of radiolabeled steroids and internal standardization of bioassays by radiolabeled squalane. Discussion of some analytical criteria related to chromatographic conditions and quantification parameters depending on position sensitive proportional counter.
J. Planar Chromatogr. 6, 421-424 (1993). HPTLC of ecdysteroids (standards and plant-derived samples) on silica separated by double development with chloroform - ethanol 4:1, sometimes followed by a single development with ethanol - ethyl acetate - water 80:20:5. Observation under UV at 254 nm; densitometry at 254 nm.
Sz. Nyiredy, A. Kakuk (eds.): Planar Chromatography 2000, Lillafüred, Hungary, 24-26 June 2000, Res. Inst. for Med. Plants, p. 151-156. Semi-quantitative OPLC of norethisterone on HPTLC silica gel with 4 mL butyl acetate - chloroform 17:3 after a pre-run with 4 mL n-hexane. Derivatization by spraying with a 10 % ethanolic sulfuric acid solution. Semi-quantitative evaluation at 366 nm. Impurities (6a-hydroxy-, 6b-hydroxy-, 10-hydroxy-, 6-keto-, 17-epi-norethisterone and nordione) can be separated and detected below 0,05 %.
Acta Chimica 117, 287-292 (1984). TLC of steroidal derivatives on silica with aq. perchloric acid solution. Identified substances: 5,6- beta dihydroxy-5-alpha -cholestane, its 3 beta-acetoxy, 3 beta-chloro-analogue; 5-hydroxy-6 beta-acrylamide-5 alpha-cholestane, its 3 beta-acetoxy, 3 beta-chloro analogue.
Reinheitsprüfung mit DC. (Glucocorticoids, testing purity with TLC.) (German). Deutsche Apotheker Zeitung 129, 1043-1044 (1989). TLC of betamethasone, dexamethasone, hydrocortisone, prednisolone and prednisone on silica with ethyl ether - dichloromethane - water - methanol 15:77:1.2:8. Detection under UV 254 nm.
J. Planar Chromatogr. 16, 268-270 (2003). TLC of the Z and E diastereomers of the O-methyloximes of testosterone and 17a-methyltestosterone on silica gel with ether - petroleum ether (30-60°C) 1:1. The RF values of these compounds could be rationalized by a quantitative structure-property relationship (QSPR) using one topological/topographical index.
J. Planar Chromatogr. 31, 72-78 (2018). HPTLC of equol in ethanolic cattle manure extract on RP-18 with n-hexane – ethyl – acetate – acetone 9:3:2. Detection by planar yeast estrogen screening (pYES) by dipping into a yeast suspension, followed by incubation at 30 °C for 4 h. After incubation, the plate was dried in a 37 °C incubator for 15 min and dipped into the combined reaction buffer followed by incubation at 37 °C for 60 min and 90 % relative humidity. The combined reaction buffer was prepared by mixing 20 mL of buffer C (5.3 g of sodium phosphate dibasic and 0.4 g of potassium chloride were dissolved in about 490 mL water, the solution was adjusted with sodium hydroxide to pH 13, 0.5 g of benzalkonium chloride were added and the mixture was filled up to 500 mL) and 0.2 mL of a freshly prepared X-Gal solution (0.05 g/mL X-Gal in DMSO). Fluorescence evaluation under UV 366 nm. The hRF value for equol was 47.
