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. Planar Chromatogr. 19, 463-466 (2006). Preparative RP-HPTLC of anthocyanin extracts (e. g. malvidine) on silica gel with five-step gradient elution with different concentrations of toluene - acetonitrile - water - formic acid - n-butanol - 2-propanol and resp. addition of tert-butylmethyl ether. After extraction of the third zone from the layer, HPTLC on RP-18 as the best stationary phase with a three-step gradient elution using methanol - water - formic acid in different ratios. Quantitative determination by absorbance measurement at 470 nm.
International Journal of Pharma and Bio Sciences 1(1), 2-4 (2010). TLC of methanol 50 % extracts of cut dried flowers of Calendula officinalis on silica gel with chloroform – methanol 19:1. The hRf value of quercetin was 43. Quantitative determination by densitometry at 366 nm. The method was linear in the range of 1-5 µg/band. The identity of quercetin in the sample was confirmed by comparing hRf values and UV spectra of sample and standard.
J. Ethnopharmacol. 158, 454-457 (2014). The authors described how the European Pharmacopoeia provides a legal and scientific reference for the quality control of medicines. The document highlighted HPTLC as a tool for the screening of herbal drugs containing certain contaminants, such as aristolochic acids._x000D_
J. Planar Chromatogr. 29, 341-346 (2016). HPTLC of artemisinin in the seeds of Artemisia annua on silica gel with n-hexane ‒ ethyl acetate ‒ acetic acid 20:10:1. Detection by dipping into anisaldehyde reagent (glacial acetic acid ‒ sulfuric acid ‒ anisaldehyde 50:1:0.5) followed by heating at 110 °C for 5 min. Quantitative determination by absorbance measurement at 540 nm. The hRF value for artemisinin was 43. Linearity was between 200 and 1000 ng/zone. The intermediate precision was below 0.7 % (n=3). The LOD and LOQ were 30 and 80 ng/zone, respectively. Recovery ranged from 82.9 to 87.1 %.
for the simultaneous determination of vulgarin and epivulgarin biomarkers in Artemisia judaica L
J. Planar Chromatogr. 31, 202-206 (2018). HPTLC of vulgarin (1) and epivulgarin (2) in the aerial parts of Artemisia judaica on silica gel with petroleum ether – acetone 7:3. Quantitative determination by absorbance measurement at 224 nm. The hRf values for (1) and (2) were 30 and 36, respectively. Linearity was in the range of 100-700 ng/zone for (1) and (2). The intermediate precision was below 1.5 % (n=6). The LOD and LOQ were 13 and 44 ng/zone for (1) and 14 and 47 ng/zone for (2), respectively. Recovery was between 97.1 and 99.6 % for (1) and 97.6 and 99.0 % for (2).
Phytochemistry 26, 261-263 (1987). Two-dimensional TLC of various proanthocyanidins on cellulose with 1) formic acid - water 3:47 and 2) butanol - formic acid - water 14:1:5. Detection with butanol - hydrochloric acid 19:1. Also HPLC on RP-18 and column chromatography on Sephadex.
J. of Natural Products 51, 1148-1152 (1988). TLC of coumarins on silica with 10% methanol in dichloromethane. Visualization by exposing to iodine vapor or spraying with phosphomolybdate reagent followed by heating.
Bestimmung mittels Spektralphotometrie und HPLC. (Bufadienolide in sqills. Determination by spectrophotometry and HPLC). Deutsche Apotheker Zeitung 130, 2175-2180 (1990). TLC of bufadienolide on silica with ethyl acetate - methanol - water 81:11:8 or chloroform - methanol - water 70:22:3,5 or ethyl methyl ketone - toluene - methanol - water - acetic acid 80:10:5:2. Detection by spraying with 50% ethanolic sulfuric acid.
