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.
Chinese J. Hosp. Pharm. (Zhongguo Yiyuan yaoxue Zazhi) 25 (1), 90-92 (2005). TLC on silica gel with chloroform - ethyl acetate - formic acid 2:2:1. Detection under UV light. Identification by fingerprint technique. Quantification by densitometry at 325 nm. Validation of the method by investigation of linearity (0.52 µg - 4.68 µg, r = 0.9992); precision (RSD = 2.20 %, n = 5); reproducibility of five time assay towards the same sample (RSD = 3.10 %); standard addition recovery (99.0 %, RSD = 0.26 %, n = 5). The results for three real life samples are given.
J. Chinese Trad. Patent Med. (Zhongchengyao) 27 (3), 272-275 (2005). TLC of the extracts on silica gel with 1) n-hexane - chloroform - methanol 15:8:2; 2) n-hexane - ethyl acetate 9:1; 3) chloroform - benzene - glacial acetic acid 7:2:1. Detection 1) by exposing to iodine vapours; 2) under UV 365 and 254 nm. Identification by comparison with the standard. Quantification of usnic acid by densitometry at 290 nm. Validation by investigating the linearity range (0.50 - 2.50 µg/spot, r = 0.999), precision (RSD = 2.26 %, n= 5, within plate, and 2.97 %, n = 5, plate-to-plate), and standard addition recovery (97.5 %, RSD = 2.61, n = 5).
Influence of diluents and adulterants. J. Liq. Chromatogr. Relat. Technol. 28, 2875-2886 (2005). TLC of the active components of „ecstasy“ (MDMA, PMA, PMMA, and ephedrine) on silica gel with 10 mobile phases. The simplex method has been employed to find the optimum composition of the eluent chloroform - dioxane - methanol - ammonia - acetonitrile 7:30:4:3:30. Detection under UV light at 254 nm.
J. Liquid Chromatogr. 8, 1265-1278 (1985). Separation of seven barbiturates on silica impregnated with 2 % copper sulfate or 2 % ethylene diamine with benzene - methanol 40:8 or benzene - acetone 40:12. Detection by spraying with 1 % aq. solution of mercurous nitrate.
Merck Spectrum 1990, 34-37. HPTLC of dansyl morphine and dansyl monoacetylmorphine on silica with methanol – NH3 25 % 99:1. Detection after drying in cold air for 20 sec, dipping in paraffin – hexane solution for 2 sec, drying in cold air and viewing under UV 366 nm. Quantification by fluorimetry.
Quantitative HPTLC in toxicology. GIT Fachz. Lab. 37, 18-22 (1993). The presently observed renaissance of TLC is closely connected with the development of modern TLC-scanning equipment. - Description of applications under quantitative aspects, e.g. determination of opiates (esp. 6-monoacetylmorphin as heroin marker), 1,4-benzodiazepines via aminobenzophenones, phenothiazines, doping agents, barbiturate derivatives and pesticides. Detection limit of morphine/6-monoacetylmorphine after prechromatographic derivatization with dansylchloride 200 - 400 pg/chromatogram zone.
J. Planar Chromatogr. 9, 286-288 (1996). HPTLC of 3,4-methylenedioxyamphetamines of the ecstasy group (MDA - 3,4-methylenedioxyamphetamine, MDMA - N-methyl-3,4-methylenedioxyamphetamine, MDE - N-ethyl-3,4-methylenedioxyamphetamine) on silica with ethyl acetate - acetone - methanol - 25% NH3 10:10:4:1. After careful removal of the mobile phase, NH3 in particular, derivatization with OBPB solution (26.3 mg in 100 ml acetone or methanol) by dipping the chromatogram three times, 2 s each. The plate was heated at 100°C for 5 min for stabilization. The reagent solution is stable for several months if stored in the refrigerator protected from light. Densitometry before derivatization at 283 nm and after derivatization at 355 nm; recording of spectra.
