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. The saved items can be printed to PDF using the print function of your web browser.
Planta Med. 84(18), 1348-1354 (2018). A subfraction (obtained through liquid-liquid partition and column chromatography) of the ethanolic extract of whole Vernonia cinerea plants (Asteraceae, subf. Cichorioideae) was further fractioned by reverse-phase SPE (solid-phase extraction) followed by preparative TLC on silica gel layer (eluent not given). For verification, zones were detected by spraying with anisaldehyde solution with 10 % sulfuric acid, followed by heating at 100 °C. Further purification by reverse-phase HPLC allowed the isolation of 6 hirsutinolide-type sesquiterpenoids (all with a oxacyclonane forming an ether bridge), including vernolides A and B.
Planta Med. 84(18), 1340-1347 (2018). Preparative TLC on silica gel for the final purification of 15 phenylethyl-chromenone derivatives (including 3 with epoxide functions), 4 sesquiterpenoids (neopetasane, dehydrokaranone, dioxoselinene, ligudicin C) and a steroid (ergostatetraenone), all isolated through multi-step column chromatography from the ethyl-acetate fraction of a methanolic extract of Aquilaria sinensis resinous wood (Thymelaeaceae). For each compound, mobile phase, RF value and yield are given.
J. Sep. Sci. 43, 3885-3901 (2020). HPTLC of erianin and gigantol in the stems of Dendrobium hercoglossum on polyamide film with methyl benzene - ethyl formate - formic acid 6:3:1. Detection by spraying with 10 % ethanol solution of sulfuric acid, followed by heating at 105 ºC.
J. Liq. Chromatogr. Relat. Technol. 42, 249-257 (2019). HPTLC of methanolic extracts from the leaves of Paulownia tomentosa on silica gel with chloroform - ethyl acetate - methanol 20:3:2. HPTLC-direct bioautography by dipping into B. subtilis cell suspension, followed by incubation at 28 °C for 2 h. Then the bioautograms were dipped into an aqueous solution of the MTT vital dye (1 mg/mL (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide), followed by incubation at 28 °C for 30 min. Further analysis by using a HPLC-DAD-MS system allowed the identification of apigenin and p-coumaric acid as highly abundant antibacterial components.
J. Planar Chromatogr. 32, 223-229 (2019). HPTLC of syringaresinol in bark pieces of Gnidia glauca on silica gel with ethyl acetate - methanol 4:1. Quantitative determination by absorbance measurement at 273 nm. The marker compound was identified by high-resolution mass spectrometry.
J. Planar Chromatogr. 32, 231-235 (2019). HPTLC of mangiferin in Canscora perfoliata on silica gel with ethyl acetate - methanol - formic acid - acetic acid - water 10:1:1:1:1. Quantitative determination by absorbance measurement at 254 nm. The hRF value of mangiferin was 53. Linearity was between 0.1 and 0.5 µg/zone. The intra-day and interday precisions were below 1 % (n=7). The LOD and LOQ were 30 and 50 ng/zone, respectively. Recovery rate was 97.5 %.
J. Planar Chromatogr. 32, 55-57 (2019). TLC of dimethyl phthalate, diethyl phthalate, di-n-butyl phthalate, diisobutyl phthalate, diallyl phthalate, and bis(2-ethylhexyl) phthalate on silica gel with petroleum ether - ethyl acetate - phosphoric acid 9:1:1. Detection by spraying with 0.1 % 2,6-dichlorophenolindophenol with the instantaneous appearance of pink-colored zones.
Chromatographia 69(3-4), 351-356 (2009). TLC of piroxicam and its degradation products on silica gel with ethyl acetate – toluene - butylamine 2:2:1. Quantification by absorbance measurement at 360 nm. It was found that piroxicam decomposes to produce pyridine-2-amine and 2-methyl-2,3-dihydro-4H-1?6,2-benzotiazin-1,1,4-trione, based on 1H NMR and LC–MS–MS qualification data.
