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:

J. Planar Chromatogr. 21, 83-88 (2008). TLC of (+)-catechin and (-)-epicatechin on silica gel with diisopropyl ether - formic acid 9:1 in an unsaturated twin-trough chamber. Detection by spraying with vanillin-sulfuric acid reagent followed by heating at 120 °C for 5 min. Quantitative determination by absorbance measurement at 490 nm.
CBS 107, 13-15 (2011). HPTLC of 5-hydroxymethylfurfural (HMF) in honey on silica gel, prewashed with methanol - water 6:1, with ethyl acetate. Quantitative determination by densitometry in absorbance mode at 290 nm. Optional detection by immersion in p-aminobenzoic acid reagent followed by heating at 110 °C for 5-10 min. The hRf value of HMF was 80. The calibration function was polynomial in the range of 0.8-80 ng/band whilst Michaelis Menten 2 regression was suitable for higher concentrations. The LOD of HMF in honey samples was 0.75 mg/kg (12 µL applied) and the LOQ 2.4 mg/kg. The method complies with the requirement of max. 15 mg/kg of HMF in honey. The results with this method were compared with those obtained by the spectrophotometric Winkler method and by HPLC-UV and mean differences were minor (3.3 % or 0.9 mg/kg). Complementary confirmation by HPTLC-MS online coupling. HMF zones identified under UV were eluted and analyzed by ESI-MS in full-scan and SIM mode.
by principal component analysis. J. Planar Chromatogr. 28, 274-279 (2015). DPPH-HPTLC bioautography assay of Hibiscus sabdariffa on silica gel with toluene - ethyl acetate - formic acid - methanol 30:30:8:5. Analysis by dipping into 0.05 % DPPH methanolic solution. Combination with liquid chromatography-quadrupole time-of-flight mass spectrometry enabled the rapid screening and identification of the antioxidants in Hibiscus sabdariffa.
Planta Medica 83(03/04), 326-333 (2017). Usnic acid, precipitated by low temperature (4 °C) from a benzene Soxhlet extract of the lichen Usnea amblyoclada, was purified by preparative layer chromatography on silica gel with chloroform – n-hexane 4:1. Detection at UV 254 nm. Yield was 1.1 % of the dried plant.
J. Ethnopharmacol. 233, 141-147 (2019). HPTLC of gentiopicrin in the dried roots and rhizomes of Gentiana scabra on silica gel with ethyl acetate – ethanol – water 8:2:1. Detection by spraying with chromogenic reagent (acetic acid – sulfuric acid – p-anisaldehyde 100:2:1). Qualitative evaluation at UV 254 nm. The hRF value for gentiopicrin was 58.
(Coumarin drugs - quality testing of the umcka drug and its preparations.) Dtsch. Apoth. Ztg. 128, 292-296 (1988). TLC of umckalin, scopoletin umckalinic acid, umckalin-7-O-glucoside on silica with ethyl acetate - formic acid - acetic acid - water 100:11:11:26. Detection under UV 365 nm after spraying with KOH solution; separation of umckalin and scopoletin with toluene - ether 50:50 saturated with 10% aqueous acetic acid.
Helv. Chim. Acta 72, 1455-1462 (1989). TLC of plant extracts containing chromonocoumarins on silica with chloroform - methanol 95:5 or chloroform - methanol - water 65:35:5 and HPTLC on RP-8 with methanol - water 7:3 or 8:2. Detection under UV 266 nm. Bioautography on silica with the plant pathogenic fungus Cladosporium cucumerinum. Also HPLC and low pressure liquid chromatography.
Phytochemistry 31, 1983-1985 (1992). TLC of hexane extract of the roots of Eupatorium riparium on silica with dichloromethane. Detection of antifungal compounds against Cladosporium cladosporioides using the TLC bioautographic assay. Prep. TLC of chromene derivatives on silica with hexane .
