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. Chinese Herb Med. (Zhongcaoyao) 22, 205-206 (1991). TLC of imperialine on silica with cyclohexane - ethyl acetate - diethylamine 6:4:1. Detection by spraying with modified potassium iodobismuthate reagent. Quantification by densitometry at 510 nm.
J. Liquid Chromatogr. 13, 1959-1965 (1990). TLC of natural waxes on silica with a solvent mixture. Detection by charring with sulfuric acid - water 1:1, and heating at 200 °C Investigation of the influence of heating time and amount of charring agent.
J. Planar Chromatogr. 3, 81-82 (1990). TLC of putrescine, spermidine, spermine and histamine (as hydrochlorides) on alumina with chloroform - triethylamine 4:1 as optimum system. Prechromatographic in situ derivatization of the samples; dansylation after addition of a saturated aqueous solution of Na2CO3 with 100 µL of dansylchloride in acetone (2.7 mg/mL). Detection and evaluation by densitometry. Easy and reproducible TLC method with high sensitivity for histamine determination.
J. Chinese Herb Med. (Zhongcaoyao) 22, 308-309 (1991). TLC of berberine, palmatine and jatrorrhizine on silica with ethyl acetate - chloroform - methanol - diethyl amine - NH3 16:4:4:1:2. Quantification by densito-metry at 342 nm.
Chinese J. Pharm. Anal. (Yaowu Fenxi Zazhi) 11, 293-294 (1991). TLC of morphine chloride on silica with ethyl acetate - methanol - NH3 86:10:4. Quantification by densitometry at 287 nm.
J. Planar Chromatogr. 5, 16-27 (1992). TLC of estrogens (estrone, equilin, equilenin, 17 a & ß-dihydroequilin, 17 a & ß-dihydroequilenin, estriol) on silica, C-2, C-8, C-18, NH2- and diol-modified, with different eluents in one- and two-dimensional separations. The optimized mobile phase based on cyclohexane and ethyl acetate provided best separation of estrogens containing C-17 hydroxy group epimers, those with a C-17 keto group were only separated in mobile phases containing triethylamine (or on NH2-layers in the absence of triethylamine). 2,4-dinitrophenylhydrazones of C-17-keto group estrogens enable their selective detection at 366/>400 nm.
J. Planar Chromatogr. 5, 62-63 (1992). TLC of DNS-streptomycin and DNS-neomycin on silica with 20% disodium monohydrogen phosphate solution for 4 cm and (after drying) with the organic phase from butanol – ether – 20% aqueous Na2HPO4 35:10:20. Quantification by fluoro densitometry at 313/>400 nm resp. 366/>400 nm. Simple TLC method for routine analysis.
Chinese J. Pharm. Ind. (Yiyao Gongye Zazhi) 22, 218-219 (1991). TLC of procaine, lidocaine and bupivacaine on silica with cyclohexane – benzene – ethylene-diamine 15:3:2. Quantification by densitometry (absorbance at 223 nm).
