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.
Lipids 17, 477-482 (1982). Preparative TLC of microbially produced metabolites of lithocholic acid and lithocholic acid-3 alpha-sulfate on silica with dichloromethane-methanol 95:5. Detection by spraying with anisaldehyde, followed by heating. The following metabolites were isolated: isolithocholic acid, 5 beta-cholanic acid, 3-keto-lithocholic acid, 5 alpha -cholestone and delta 3-cholenic acid.
Shaanxi Provin. J. Med. (Shaanxi Yixue Zazhi) 18, 28-30 (1989). TLC of free bile acids on silica with isooctane - isoproyl ether - acetic acid - butanol - water 10:5:5:3:1. Detection by spraying with a solution of phosphomolybdic acid. Quantification by densitometry.
J. Liq. Chromatogr. & Relat. Technol. 30, 405-418 (2007). TLC of cholic acid, glycocholic acid, glycolithocholic acid, deoxycholic acid, chenodeoxycholic acid, glycodeoxycholic acid, and lithocholic acid on silica gel impregnated with 1 %, 2.5 %, and 5 % aqueous solutions of copper(II) sulfate, manganese sulfate, nickel sulfate, and iron(II) sulfate, using mixtures of n-hexane - ethyl acetate - acetic acid 22:20:5; 25:20:2; and 22:22:5. The use of the mobile phase 25:20:2 on silica gel impregnated with a 5 % solution of copper(II) sulfate allowed separation of all neighbouring pairs of investigated bile acids, compared to non impregnated plates. Detection of bile acids by spraying with 10 % aqueous sulfuric acid reagent, followed by heating at 120 °C for 10 min.
J. Liquid Chrom. 9, 1759-1782 (1986). HPTLC of free and conjugated ecdysteroids on silica with chloroform/methanol 8:2. Differentiation of polar ecdysteroids on silica with ethyl acetate/ethanol/water 2:8:1. Detection under UV.
(Hungarian). Acta Pharmaceutica Hungarica 69, 72-76 (1998). TLC of 20-hydroxyecdysone on silica gel with dichloromethane - 96% ethanol 17:3 or chloroform - benzene 25:5. Densitometry at 254 nm.
Chinese J. Pharm. Anal. 27 (3), 412-413 (2007). TLC of dexamethasone acetate on silica gel with dichloromethane – methanol 9:1. Detection under UV 254 nm.
Neighbouring group participation V. (0-4) Neighbouring group participation and fragmentation in the 16-hydroxymethylandrost-5-ene-3,17-diol series. Acta Chimica 110, 429-440 (1982). TLC of 16-hydroxymethylandrost-5-ene-3,17-diol and isomers on silica with a) methanol - benzene 1:99, b) methanol - benzene 5:95, c) acetone - benzene - petrol ether 30:35:35. Detection with 50 % aq. phosphoric acid and by heating at 100 -120 °C for 15 minutes.
J. High Resol. Chromatogr. 6, 617-620 (1983). HPTLC of bile acid methyl esters on silica and octadecyl-bonded silica with different solvent systems, e.g. methanol - water 95:5, 9:1, 8:2; acetonitrile-water 95:5, 85:15, 75:25; hexane - ethyl acetate - acetic acid 20:10:0.5, 10:20:0.5, 10:40:2, hexane - isopropanol - acetic acid 50:10:1, 40:10:1, 30:10:1. late development with an appropriate solvent system for 6 cm. Detection by spraying with 0.5 % vanillin in sulfuric acid-ethanol 4:1 and heating at 100 °C.
