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.
Chromatographia 52 (3/4), 175-178 (2000). Investigation of methods for the separation of test mixtures of 10 flavonoids using isocratic RP-HPLC, gradient RP-HPLC, and a coupled isocratic RP-HPLC-NP-TLC system. TLC of the flavonoid fractions separated on RP column, by using 3-step gradient elution with methanol - ethyl acetate, giving a complete separation of the investigated compounds.
J. Chinese Trad. Patent Med. (Zhongchengyao) 25 (10), 798-801 (2004). TLC on silica gel with 1) ethyl acetate - butanone - formic acid - water 10:7:1:1; 2) benzene - acetone 10:1; 3) petroleum ether - ethyl formate - glacial acetic acid 18:1:1. Detection 1) under UV 365 nm, 2) by spraying with 5 % solution of vanillin - acetic acid - perchloric acid and heating at 105 ºC, 3) by spraying with 10 % H2SO4 in ethanol and heating at 105 ºC. Identification by fingerprint techniques. Quantitation of icariine by HPLC.
CBS 97, 2-5 (2006). HPTLC of gangliosides on silica gel with chloroform - methanol - water 24:17:4 and addition of 2 mM CaCl2, after chamber saturation with filter paper for 3 h, over 80 mm, followed by drying for 5 min at room temperature. Detection by dipping in orcin solution (0.3 % (w/v) in 3 M H2SO4) followed by heating at 100 °C for 3 min. Alternative detection of GM3-bands by derivatization with primulin (0.02 % (w/v) in aceton - water 4:1). Quantitative determination by direct IR-MALDI-o-TOF-analysis. The limit of detection for GM3 was about 50 ng/zone.
CBS 102, 2-3 (2009). A semi-automatic interface for hyphenation of TLC with mass spectrometry, which was based on the ChromeXtractor by Luftmann, is introduced. The interface is connected to a HPLC pump and the MS. By means of an extraction piston any target zone can be eluted from a TLC/HPTLC plate directly into the MS. Example: for identification of the zone at hRf 15 in a standard mixture of caffeine, paracetamol, and acetylsalicylic acid the mass spectrum of the zone is recorded. After subtraction of a background spectrum a mass spectrum free from system peaks is obtained, which shows mainly substance signals - here the mass signal m/z 195 [M+H]+ for caffeine.
Rapid Commun. Mass Spectrom. 23, 2711-2723 (2009). HPTLC in combination with matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) was used for the analysis of complex lipid mixtures. For the separation of lipids one-dimensional HPTLC on silica gel aluminum foil was used with a two-phase mobile phase. The combination with MALDI-MS allowed the identification of 70 distinct lipid species and the analysis of even minor lipid classes from only very small volumes of human plasma (50 µL).
Phytochem. Anal. 24, 47-52 (2013) TLC of 22 acylated phenolic compounds on silica gel with acetonitrile - water - chloroform - formic acid 12:3:2:1, followed by dipping into 0.2 % methanolic 2,2-diphenyl-1-picrylhdrazyl solution (DPPH radical reagent) for 5 s and kept in the dark for 30 min. Free radical scavenging activity of the acylated phenolic compounds was assessed by coupling with the image processing software ImageJ .
J. Ethnopharmacol. 158, 487-494 (2014). The review described special techniques such as DNA fingerprinting, nuclear magnetic resonance, near infra red and (bio)sensors that combined with chromatographic techniques provide complementary analytical methods able to give rapid analysis responses, to operate directly on complex matrices, to be portable and to have fast analysis times. TLC is mentioned in the identification section, HPTLC is mentioned in the test for aristolochic acids in herbal drugs.
Trends Anal. Chem. 85, 75-84 (2016). This review describes different approaches for characterization of fossil resins (including amber and all their various types), including chromatographic methods and the application of TLC for separation and purification of compounds and its coupling with mass spectrometry. Fossil resins are often adulterated with modern resins and some rare and precious fossil resin specimens are imitated by more abundant, cheaper fossil specimen (for example succinite – Baltic amber is often imitated by copal).
