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.
Rev. Bras. Farmacogn. 24, 133-140 (2014). HPTLC fingerprint of the leaves of Lawsonia inermis L. on silica gel with ethyl acetate - formic acid - water 82:9:9. Detection by spraying with natural product reagent (0.5 % diphenylborinic acid aminoethylester in ethyl acetate), followed by drying in the open air and dipping into macrogol reagent (0.5 % polyethylene glycol 400 in dichloromethane). Qualitative determination at UV 366 nm. Samples from Morocco, India, Pakistan, Iran, Cameroon, Tunisia, Yemen and Egypt showed three peaks at hRF 42, 45 and 52.
Acta Chimica 124, 485-489 (1987). TLC of chromonoid compounds and their degradation products on silica with benzene - ethanol 9:1. Detection under UV 254 and 366 nm. Also spraying with 1% FeCl3x6H2O in 80% aq. ethanol solution, concentrated sulfuric acid. Detection limit 0.1-0.8 µg/mL.
Chinese J. Plant Physiol. (Zhiwu Shenglixue Tongxum) (3), 51-53 (1990). TLC of chlorophylls and carotenoids on polyacrylamide with petrol ether (60-90°) - propanol - acetone - methanol 176:4:15:5. Detection by densitometry.
J. AOAC Int. 78, 491-496 (1995). TLC of bixin, lycopene, canthaxanthin, ß-apo-8'-carotenal on silica with hexane - acetone 10:9, petrol ether (40-60 °), dichloromethane - ethyl ether 9:1, petrol ether (65 - 95 °) - benzene 1:1. Quantification after elution by spectroscopy.
Biochemical Systematics and Ecology 28, 443-455 (2000). TLC of neoxanthin, violaxanthin on silica gel with heptane - acetone 3:2.
CLB Chemie in Labor und Biotechnik 47, 262-263 (1994). HPTLC screening of carcinogenic amines in textiles on silica with dichloromethane - acetonitrile 5:1. Derivatization by diazotation and coupling with N-(1-naphthyl)-ethylenediammonium dichloride. Visual evaluation (pink to blue zones on a pale background). For confirmation of positive results a 15 step AMD gradient on silica from 80% dichloromethane - acetone 1:1 and 20% hexane to 20% dichloromethane - acetone 1:1 and 80% hexane follows. Alternative chromatography on silica with diisopropyl ether - pentane - diethyl amine 12:8:1. Quantification by densitometry (absorbance) at 200, 230, 280 and 360 nm (multi-wavelength-scan). The detection limit of 20 derivatized amines is between 20-200 ng and of not derivatized between 20-400 ng. Sample preparation includes treatment with dithionite reagent, cleaving azo dyes into their component amines. Very effective screening method. Similar topic published: "Identification and determination of carcinogenic amines of the MAK value list III A1/A2." in Int. Lab. Nov., 29-30 (1996); and "Nachweis und Bestimmung verbotener Amine aus der Spaltung von Textil-Azofarbstoffen. (Identification and determination of banned amines derived from textil azo dyes.) in GIT Fachz. Lab. Spez. Chromatogr. 2, 92-94 (1995).
J. AOAC Int. 91, 1387-1396 (2008). HPTLC on silica gel with chloroform - methanol 9:1 in the first direction for curcumin, demethoxycurcumin, bis(demethoxy)curcumin, and the synthetic dye metanil yellow, and with toluene - hexane - acetic acid 50:50:1 for sudan I and sudan IV in the second direction. Quantitative determination by absorbance measurement at 420 nm for curcumin and metanil yellow, at 491 nm for sudan I, and at 520 nm for sudan IV.
