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.
CBS 88, 9-11 (2002). HPTLC of flavonoids, hypericin and pseudohypericin on silica gel and diol phases (for quantification of hypericin) respectively, with ethyl acetate - dichloromethane - formic acid - acetic acid - water 100:25:10:10:11. Detection by dipping the warm plate in modified natural products reagent (0.5 % in ethyl acetate). Selective HPTLC of hyperforin on silica gel with toluene - dichloromethane 4:1. Visual detection by spraying with Godin reagent. Quantitative determination by absorbance measurement at 310 nm without derivatization.
Planta med. 70, 152-159 (2004). Analytical HPTLC on silica gel RP-18 and preparative TLC on silica gel of piperine, piperamine, piperlonguminine, and methyl piperate with n-hexane - ethyl acetate 1:1. Detection by spraying with 1 % cerium sulfate - 10 % aqueous sulfuric acid followed by heating on a plate heater.
J. Planar Chromatogr. 17, 147-148 (2004). TLC of capsaicin on silica gel with concentration zone with toluene - acetone - chloroform 8:7:5 and 9:6:5. Detection by spraying with a 0.25 % ethanolic solution of 2,6-dichloroquinone-4-chlorimide or by exposure to iodine vapor.
J. Planar Chromatogr. 18, 234-239 (2005). TLC of Evolvulus alsinoides extracts and the marker EA 1, i.e. 3beta,23,24-trihydroxyolean-12-en-28-oic acid, on silica gel with n-hexane - ethyl acetate 7:3 in a saturated chamber. The marker EA 1 was detected under UV light at 366 nm as a yellow fluorescent band of Rf 0.8. Quantitative determination by absorbance measurement at 232 nm (=UV max of EA 1). Limit of detection 11.6 ng; satisfactory recovery from 93.3 to 96.6 %. The marker was isolated from the aerial parts of Evolvulus alsinoides by preparative TLC.
Planta Med. 71, 659-665 (2005). Preparative TLC of robustaflavon 7,4’,4’’’-trimethyl ether on silica gel with chloroform - methanol 3:1, of robustaflavone 4’,4’’’-dimethyl ether on RP18 with methanol - water 6:1, of 2,3-dihydroamentoflavone 7,4’,7’’’-trimethyl ether on silica gel with ethyl acetate - methanol 4:1, of 2,3-dihydroamentoflavone-7,4’-dimethyl ether on RP18 with methanol - water 8:1, and of 2’’,3’’-dihydroisocryptomerin 7-methyl ether on silica gel with chloroform - methanol 3:1. Detection under UV light at 254 nm.
J. Liq. Chrom. & Rel. Technol. 27, 2421-2439 (2004). TLC of e. g. delta8-tetrahydrocannabinol, cannabigerol, cannabigerolic acid, cannabidiolic acid, and (-)-delta9-(trans)-tetrahydrocannabinolic acid on RP18 with methanol - 5 % acetic acid 19:1. Detection under UV light at 254 nm and by spraying with modified anisaldehyde - sulfuric acid spray reagent. For selective detection of cannabinoids, the plate was sprayed with 0.5 % fast blue B salt in water, followed by 0.1 M NaOH.
Planta Med. 71, 759-763 (2005). Preparative TLC of hyemalol, nerolidol, and cadinol on silica gel with hexane - ethyl acetate 9:1. Detection under UV light at 254 nm.
Planta Med. 71, 412-415 (2005). TLC of kaempferol 3-O-alpha-L-[2-(Z)-p-coumaroyl-4-(E)-p-coumaroyl]rhamnopyranoside and kaempferol 3-O-alpha-L-[2,4-di-(E)-p-coumaroyl]rhamnopyranoside on silica gel with dichloromethane - methanol 6:1. Observation under UV light at 254 nm and dipping in vanillin - sulfuric acid resulting in yellow-green spots.
