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

Chinese J. Herb Med. (Zhongcaoyao) 24, 128-130 (1993). TLC of palmityl-ß-sitosterol, lupenone, 24-methylene-cycloartenol, and ß-sitosterol on silica with chloroform - benzene 9:1. Detection by spraying with 5% phosphomolybdic acid. Quantification by densitometry (absorbance) at 625 nm.
J. Planar Chromatogr. 13, 437-442 (2000). TLC of cholesterol and oxysterols (7-ketosterol, 25-hydroxycholesterol, 7b-hydroxycholesterol, cholesterol-5a,6a-epoxide, cholestane-3b,5a,6b-triol) on silica gel with chloroform-acetone 9:1. After spraying with Liebermann-Burchard reagent the spots were quantified by densitometry in reflectance mode at 360 nm. Also TLC of silylated oxysterols on silanized silica gel with n-hexane - ether - methanol 38:2:1. Simple, sensitive, and reproducible method.
J. Sep. Sci. 33, 3110-3118 (2010). HPTLC of bile acids and their derivatives on 1) RP-18, 2) RP-18W and 3) cyano phase with methanol - water mixtures. The volume fraction of organic solvent in the mobile phase ranged from 70-90 % for (1), 50-70 % for (2) and 45-65 % for (3). Detection by spraying with a solution of manganese chloride in sulfuric acid, followed by heating at 100-120 °C for 10 min. Quantification by absorbance measurement at 254 nm and 365 nm.
J. Shenyang Pharm. Coll. (Shenyang Yaoxueyuan Xuebao) 6, 197-198 (1989). TLC of bile components on silica with isopentanol - acetic acid - water 18:5:3. Identification by comparing the Rf values with those of standards.
III. Separation on various stationary phases. J. Liq. Chrom. & Rel. Technol. 27, 2613-2623 (2004). TLC of cholic, glycocholic, glycolithocholic, deoxycholic, chenodeoxycholic, glycodeoxycholic, and lithocholic acid on different preparations of silica gel and a mixture of silica gel and Kieselguhr with n-hexane - ethyl acetate - acetic acid in various volume compositions; successful separation was achieved with the compositions 4:4:1 and 22:21:5. Detection by 10 % aqueous sulfuric acid followed by heating at 120 °C for 20 min. Densitometric measurement at 250 nm.
J. Chromatogr. 408, 445-448 (1987). TLC of ecdysone, makisterone A, polypodine B, ponasterone A, ponasterone C and polypodine B 2-cinnamate on silica with various solvent systems based on hexane - dichloromethane and dichloromethane - methanol using AMD. Detection by visualizing under UV 254 nm; densitometry by absorbance at 260 nm. Comparison of the results with those from manual multiple development and single development.
Chromatographia 48, 145-148 (1998). TLC of ecdysteroids from Serratula tinctoria and Serratula wolffii (Asteraceae) on silica gel, repeated development with dichloromethane - ethanol 4:1 and chloroform - methanol - benzene 25:5:3. Quantitation by densitometry at 254 nm. Comparison of the results with those obtained by MEKC.
Chinese J. Pharm. Anal. 28 (3), 470-471 (2008). TLC of glucocorticoid in TCM formulations extracted with chloroform – methanol 9:1 on silica gel with dichloromethane – diethyl ether – methanol – water 385:60:15:2. Detection by spraying with a solution of tetrazolium blue chloride. Successful separation and identification of five glucocorticoids.
