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.
Planta Medica 83(01/02), 143-150 (2017). Preparative TLC on silica gel H to purify amide alkaloids from column chromatography apolar subfractions of aerial part methanolic extracts of: a) Piper flaviflorum: decenoylpiperidide (petroleum ether – acetone 10:1), N-methoxycinnamoyl-pyrrolidine, dihydropiperyline, stigmalactam, chingchengenamide A (petroleum ether – ethyl acetate 8:1); and b) P. sarmentosum: methylenedioxyphenyl-undecadienoyl/undecatrienoyl-pyrrolidine (petroleum ether – acetone 1:2), cinnamoyl-hydroxypyrrolidine and deacetylsarmentamide B (chloroform – methanol 9:1); detection with Dragendorffʼs reagent.
J.A.O.A.C. 70, 1-14 (1987). 1- and 2-dimensional TLC of uric acid and derivatives from organ extracts or infested foodstuffs on cellulose. Method precision ± 4.6%, detection limit 5 µg, visualization with arsenophospho- tungstic acid, quantification by densitometry or spectroscopic techniques.
I. J. Chromatogr. 542, 531-561 (1991). TLC of 1.4-thiazolidinones on silica with one- and two-component solvent systems. Investigation of the effects of various properties of developing solvents and migrating species on Rf values. Quantification by spectrophotometry after elution.
Cyclic amidines. J. Planar Chromatogr. 8, 129-133 (1995). HPTLC is a useful technique for elucidating the mechanisms of organic reactions and for monitoring their kinetics when it is suspected that the usual UV method does not give reliable results. The progress of the basic hydrolysis of several 1H-4,5,6,7-tetrahydro-1,3-diazepine derivatives has been followed by HPTLC.
CBS 90, 12-13 (2003). TLC of oxazoline Ia on aluminum sheets RP-18 with methanol over 10 mm, followed by water - acetonitrile 1:1 over 55 mm. Ion pair chromatography of oxazoline Ia with phosphate buffer - acetonitrile 1:1 over 60 mm after dipping in 2 mM cetyltrimethylammonium bromide. TLC of oxazoline Ib and Ic with phosphate buffer - acetonitrile - dioxane 4:3:3 over 65 mm. Determination by absorbance measurement at 200 nm (oxazoline Ia and Ib) and 262 nm (oxazoline Ic) respectively.
Acta Chimica 112, 335-341 (1983). TLC of 3-benzoyl-4- phenyl-2-pyrazolines on silica with petrol ether - acetone 1:1.
J. Liquid Chromatogr. 13, 1943-1957 (1990). TLC on silica with methanol - dichloromethane - acetic acid 6:3:0.75. Detection by dipping into iodoplatinate reagent. Quantification by densitometry at 525 nm. SurfadoneTM QSP (Dimethylsteramidopropyl[(2-pyrrolidonyl)methyl]ammonium chloride)
J. Planar Chromatogr. 13, 414-419 (2000). OPLC of 13 benzodiazepines (alprazolam, brotizolam, carbamazepin, temazepam, chlordiazepoxide, cinolazepam, clobazam, clonazepam, diazepam, nitrazepam, midazolam, medazepam, prazepam) on HPTLC silica gel with 8 mobile phases (benzene - chloroform - nitromethane 492:313:195; chloroform - dichloromethane - methyl ethyl ketone 809:115:76; acetonitrile - chloroform - toluene 136:651:213; chloroform - ethyl acetate 825:175; acetone - chloroform-methanol 28:876:96; chloroform - dioxane - toluene 784:154:62; acetonitrile - chloroform - tetrahydrofuran 268:840:132; acetic acid - chloroform - n-butanol 95:862:43). Detection under UV; densitometry at 240 nm. According to the results Snyder's endogeneous solvent strength (Si), proton donator (Xe), proton acceptor(Xd), and dipole(Xn) parameters are not satisfactory for complete description of a solvent mixture used as mobile phase.
