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. Liq. Chrom. Rel. Technol. 27, 2087-2100 (2004). HPTLC of tetrandrine on silica gel with toluene - ethyl acetate - methanol - 28 % ammonia 100:100:50:3. Detection under UV light at 366 nm, and under white light after reaction with iodine (yellowish zones). If the plate is subsequently derivatized with anisaldehyde solution, the alkaloids show a strong blue fluorescence under UV light at 366 nm. Quantitative determination at 210 nm. The calibration curve is linear for 50 - 112.5 ng tetrandine per zone. Also HPTLC of aristolochic acids (AAs) on silica gel with the upper phase of toluene - ethyl acetate - water - formic acid 20:10:1:1 and derivatization with tin(II) chloride (to be prepared freshly: dissolve 1 g tin(II) chloride•2H2O in 1.5 mL 36 % hydrochloric acid diluted with 8 mL water), followed by heating at 100 °C for 1 min and evaluation under UV light at 366 nm. The method allows detection of 1 ppm of AA.
J. Pharm. Biomed. Anal. 37, 817-821 (2005). CO2 extracts of Harpagophytum procumbens root was evaluated by HPLC and HPTLC for harpagoside contents. HPTLC on silica gel with ethyl acetate - methanol - water 77:15:8 in saturated ADC chamber. Detection by dipping into anisaldehyde reagent followed by drying at 120 °C for 5 min. Quantitative determination by absorbance measurement at 509 nm. The linearity range was 0.04-0.40 mg/mL. The HPTLC method was less time consuming than HPLC, needing almost no sample pre-treatment. 15 different CO2-extracts of the plant were analysed.
Planta Med. 71, 733-738 (2005). Preparative TLC of (+)-ulein on silica gel with n-hexane - dichloromethane - methanol - diethylamine 25:20:4:1 and n-hexane - ethyl acetate - methanol - diethylamine 25:20:4:1. Detection under UV light at 254 nm.
J. pharmac. Sci. 70, 89-91 (1981). Two-dimensional TLC of 8 ginsenosides on silica RP-2 with 1a) chloroform - methanol - ethyl acetate - butanol - water 4:4:8:1:2, 1b) chloroform - butanol - methanol - water 4:8:3:4, 2) chloroform - methanol - water 13:7:2 (lower phase). Detection by spraying with 1 ml p-anisaldehyde + 1 ml H2SO4 in 100 ml methanol and drying at 120 °C.
Planta Med. 72, 488-493 (2006). Analytical and preparative TLC of ebenosin (8-(1,1-dimethylallyl)formomonetin) and 3 known isoflavonoids on silica gel with dichloromethane - hexane 3:2. Detection under UV light at 254 nm.
J. Chromatogr. Biomed. Applic. 272, 157-165 (1983). HPTLC of fluphenazine on silica with toluene - acetone 6:4. After evaporation of solvent the plate is placed in 5 % paraffin oil in toluene for 15 minutes. After evaporating the toluene, exposure to UV light for 15-20 minutes. Fluorometry at 254 nm.
Planta Med. 70, 828-833 (2004). Preparative TLC of driportlandin, portlanquinol as well as formonetin and davidigenin on silica gel (by x-fold development) with dichloromethane - methanol 49:1 (2 x), dichloromethane - diethyl ether 19:1, dichloromethane - ethyl acetate 19:1 to 47:3; chloroform - ethyl acetate 9:1 (4 x), and dichloromethane - methanol 19:1 (2 x). Detection under UV light at 254 nm and by spraying with sulfuric acid - acetic acid - water 1:20:4, followed by heating.
J.A.O.A.C. 66, 881-883 (1983). TLC of sulfathiazole, sulfapyrilline, sulfamethazine, sulfaquinoxaline, sulfadimethoxine, sulfabromomethazine on silica with 1a) methanol for 1 cm, 1b) chloroform - tert. butanol 8:2 for 6 cm, 1c) chloroform - tert. butanol 8:2 for 10 cm. Between each development drying of the plate for 1 minute at 110 °C. Detection by dipping into fluorescamine solution. Fluorometry.
