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.
J. Liq. Chromatogr. Relat. Technol. 39, 281-285 (2016). HPTLC bioautography of Potentilla species on silica gel with diethyl ether – methanol – formic acid 150:50:5:1. Direct bioautography by dipping into a bacterial suspension of Bacillus subtilis for 8 s, following incubation at 37 °C for 17 h. Visualization by spraying with 0.2 % MTT (thiazolyl blue tetrazolium bromide) aqueous solution, followed by incubation at 37 °C for 0.5 h.
root extract via HPTLC–UV/Vis/FLD–EDA–MS. J. Planar Chromatogr. 31, 79-86 (2018). HPTLC with effect-directed analysis (EDA) for (bio)profiling of Pimpinella saxifraga root. HPTLC on silica gel with 1) ethyl acetate – methanol – acetic acid 8:3:1 for polar separation, and 2) toluene – ethyl acetate – acetic acid 20:5:1 for apolar separation. Ten different detections were shown on one HPTLC plate cut into sections. Detection of absorbing compounds under A) white light and B) UV 254 nm and C) fluorescent ones under UV 366 nm. Three plate sections were used for microchemical derivatizations for D) detection of flavonoids after derivatization with diphenylborinic acid 2-aminoethylester reagent, followed by dipping into a polyethylene glycol 400 solution, E) universal detection with anisaldehyde sulfuric acid reagent, and F) detection of glycosides with diphenylamine aniline reagent. Effect-directed detection of G) DPPH scavenging compounds, antimicrobials via H) A. fischeri and I) B. subtilis bioassays, and J) AChE inhibitory compounds was also performed. Multi-detection showed multi-potent zones with hRF values of 19, 24, 49 and 78, which were exemplarily further characterized by HPTLC–ESI–MS in both ionization modes. A weak estrogen-effective zone was also observed via HPTLC–planar yeast estrogen screen (pYES) bioassay on RP-18 with n-hexane – toluene – ethyl acetate 6:3:4 or, after optimization, toluene – ethyl acetate 1:1.
J.A.O.A.C. 67, 563-565 (1984). TLC of chloramphenicol on silica with ethyl acetate. Detection: 2 minutes exposure in jar containing solid calcium hypochlorite, 45 sec. in jar containing 37 % formaldehyde, spray lightly with aq. solution containing 1 % starch + 1 % KI. Detection limit: > 60 ng.
J. Agric. Food Chem. 34, 274-276 (1986). TLC of monensin A sodium salt on silica with carbon tetrachloride - benzene - methyl cellosolve 8:1:1 as eluent. Quantitation after removal and extraction with FAB-MS; in addition semiquantitative determination using a TL bioantographic assay (DONOHA & KLINE, Antimicrob. agents, Chemother. 1968, 763-766) with very good agreement between both methods.
Simultaneous analysis of seven tetracyclines in honey. J. Chromatogr. 400, 253-261 (1987). TLC of residual oxytetracycline, tetracycline, chlortetracycline, doxycycline, methacycline, dimethylchlortetracycline and minocycline in honey on silica and RP-8 silica with chloroform - methanol - 5% aqueous Na2EDTA 65:20:5 (lower phase) and methanol - acetonitrile - 0.5M aqueous oxalic acid 1:1:4 (pH 3.0), resp. Detection by spraying with 0.2M aqueous magnesium chloride and 10% TEA in methanol, resp., and then observing under UV at 360 nm. Detection limits 0.1 ppm in honey.
J. Chromatogr. 463, 469-473 (1989). Description of a number of TLC systems and spray reagents for separating and identifying the cation and anion parts of benzathine and embonic acid salts of ampicillin, amoxycillin, cephalexin and talampicillin embonate. Use of the methods for assessing the purity of the synthesized embonate and benzathine salts of ß-lactam antibiotics.
J. Agric. Food. Chem. 38, 538-541 (1990). TLC on silica RP-18 with methanol - acetonitrile - water 1:1:1, visualization by short-wave UV and by spraying with diazotised sulfanilic acid.
J. Planar Chromatogr. 5, 62-63 (1992). TLC of DNS-streptomycin and DNS-neomycin on silica with 20% disodium monohydrogen phosphate solution for 4 cm and (after drying) with the organic phase from butanol – ether – 20% aqueous Na2HPO4 35:10:20. Quantification by fluoro densitometry at 313/>400 nm resp. 366/>400 nm. Simple TLC method for routine analysis.
