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:

- 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.
(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.
J. Liq. Chromatogr. Relat. Technol. 32, 3056-3065 (2009). HPTLC of steroid compounds (androsterone, epi-androsterone, dehydroepi-androsterone, testosterone, stigmasterol, ß-sitosterol, estradiol, hydrocortisone, and cholesterol) on RP-18 with methanol - water and acetonitrile - water in different volume compositions. Detection by spraying with sulfuric acid - methanol 1:9, followed by heating at 120 ºC for 15 min. The chromatographic parameters of lipophilicity of the studied steroids were determined.
II Reaktionen der Epimeren 14,15-Epoxide und des 1-beta,16-beta -Epoxids der Oestratrien-Reihe mit Acetonitril und BF3-Etherat. Ritter reactions on steroids. II. Reactions of the epimers 14,15-epoxides and15-beta, 16-beta-epoxides of the estratriene series with acetonitrile and BF3 ethoxylate.) Acta Chimica 111, 173-187 (1982). TLC of 14-alpha, 15-beta -epoxide estratriene; 15-beta,16-beta-epoxide estratriene; 14-beta, 15-beta-epoxide estratriene on silica with a) methanol -benzene 1:99 and 5:95; b) acetone - benzene 10:90; on silica HF 254 with benzene - acetone - ethanol 20:5:1. Detection by spraying with phosphoric acid or H2SO4-vanillin and heating at 140 °C.
Coll. czechoslov. chem. comm. 48, 2051-2063 (1983). TLC of 5,6-unsaturated A-nor-3,5-secosteroids on silica with a) ligroin-ether 1:1, 9:1, 7:1, 19:1, 25:1, b) benzene, c) pentane - ether 24:1.
J. Chromatogr. 367, 323-334 (1986). TLC of some rifamycins and steroids on diphenyl-bonded silica with various solvents, including non-aqueous and aqueous binary mixtures. Proposal of a dual retention mechanism. Interactions of the residual silanol groups seem to prevail when using lipophilic solvents as the mobile phase, whereas interactions with bonded aryl. groups dominate when high polarity alcoholic or aqueous mixtures are being used. Diphenyl silica precoated plates, rifamycins, steroids, mobile phase composition
J. Agric. Food Chem. 38, 1667-1673 (1990). Two step-TLC on silica with toluene - methanol 1:1 for 5 cm, after drying with toluene to 16 cm. Detection of tri-, di- and monoacylglycerols and free fatty acids by exposing to iodine vapor; of cholesteryl esters, cholesterol, cholesterol oxides and phospholipids by spraying with 50% sulfuric acid and heating at 110°C for 5 min. Quantification by determining the 14C activity.
J. Planar Chromatogr. 5, 251-354 (1992). TLC of 21 amides of 11a-hydroxyprogesterone 11-hemisuccinates on RP-2, RP-8 and RP-18 silica with 3 different eluent systems (aqueous methanol (pH ca. 8); aqueous methanol adjusted to pH 1 with HCl; methanol in 0.01 M phosphate buffer). Detection under UV 254 nm. In addition study of the correlation between structure and retention.
Analyst 119, 2571-2575 (1994). TLC on silica with 1) hexane - ether - dichloromethane 5:9:6, 2) chloroform - acetone 9:1, 3) cyclohexane - ethyl acetate - ethanol 24:16:1, 5) toluene - methanol - water 1:15:4, 6) hexane - dichloromethane - acetonitrile 8:2:1. Detection by spraying with N-methyl-N-(trimethylsilyl)-trifluoroacetamide solution and viewing under UV 366 nm. Identification by comparison of Rf values and fluorescence colors.
