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:

(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. Planar Chromatogr. 1, 116-122 (1988). Reversed- phase TLC of 23 ecdysteroids on 3 different types of octadecyl-bonded silica and on a cyanopropyl bonded silica with methanol - water based solvent systems. Discussion of the differences in chromatographic selectivity between the various TLC plate types and the effect of various functional groups on the chromatographic properties of the ecdysteroids.
J. Liq. Chrom. & Rel. Technol. 26, 2629-2649 (2003). Review of planar chromatography of ecdysteroids. Separation of various ecdysteroids is detailed using both straight-phase and reversed-phase thin-layer chromatography. The generally used special techniques, such as two-dimensional TLC, forced-flow TLC, displacement mode of development, etc., are also specified. The particular behavior of certain ecdysteroids is discussed. Materials and methods frequently used for ecdysteroid separation are described like e.g. stationary phases, mobile phases, detection methods, screening and identification of plant ecdysteroids, analysis of 20-hydroxyecdysone through the vegetation of plants, lipophilicity of ecdysteroids, analysis of ecdysteroids on RP-TLC plates, FF-TLC, AMD, 2D-TLC, displacement TLC, and hyphenated techniques.
(Wib.). Chromatographia 25, 627-630 (1988). TLC on silica with ethyl acetate - methanol - NH3 85:10:5. Detection under UV 254 nm; densitometry. TLC method used for monitoring the isolation of ecdysteroids by CC and droplet countercurrent chromatography (DCCC) and for controlling the homogeneity of pure products.
J. Planar Chromatogr. 17, 335-341 (2004). TLC and HPTLC of 29 ecdysteroids (e. g. 20-hydroxyecdysone, polypodine B, 2-deoxyintegristerone, ajugasterone C, isovitexirone, muristerone A, turkesterone, makisterone C, rubrosterone, poststerone, ecdysone, herkesterone) on silica gel, RP-18, and cyano phase with four mobile phases enabling separation of all the ecdysteroids from each other in at least one system.
