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.
- Simple thin-layer chromatographic identification of active principles in finished products. Pharm. Ind. 56, 478-483 (1994). TLC of albendazole and mebendazole on silica with hexane - ethyl acetate - acetic acid 7:2:1. Detection under UV 254 nm, by exposing to iodine vapor. and by spraying with Dragendorff / Ce(SO4)2.
(Araliaceae). J. Planar Chromatogr. 7, 474-476 (1994). TLC of hederasaponin C, a-herein, rutin on silica with chloroform - methanol - water 64:50:10. Detection by spraying with vanillin reagent (5 % vanillin in 1% aqueous sulfuric acid - ethanol 7:3). Quantification by spectrophotometry in absorbance/reflectance mode at 565 nm.
J. Planar Chromatogr. 8, 36-38 (1995). TLC of Tinuvin 633 (polyolefin stabilizer) on cellulose (prewashed with the mobile phase) with 2-propanol - 25% acetic acid - toluene 40:40:4. Detection by exposure to iodine vapor. Semiquantitative evaluation via comparison of the sizes of sample spots.
J. Planar Chromatogr. 9, 217-220 (1996). TLC of the degradation products of ethylenebisdithiocarbamate (i. a. ethylenethiourea, ethyleneurea, urea, and ethylenediamine on silica with acetone, acetone - water 99:1, 95:5, 90:10, and ethanol. Visualization reagents were sodium nitroferricyanide solution, iodine vapor and Ehrlich's reagent.
A regression study employing the ladder of power. J. Planar Chromatogr. 9, 126-128 (1996). TLC of diazepam, oxazepam, and chlordiazepoxide on silica with chloroform - methanol 9:1. Quantification by densitometry in the reflectance mode at 254 nm (absorbance).
TLC and HPLC of cinnamon and its ingredients (eugenol, cumarine, cinnamaldehyd and linalool). There are different sorts (Cinnamomum ceylanicum, Saigon cassia and Cassia korintji) of cinnamon with different ingredients, e.g. Cinnamomum ceylanicum is missing cumarine. TLC on silica with dichloromethane up to 7 cm. The activity of the layer is adjusted with sulfuric acid dilutions - best relative humidity was 40%. Derivatization by anisaldehyde- or vanillin-sulfuric acid reagent and heating at 100-110°C for 10 min. Additionally spraying with potassium hydroxide to make cumarines fluorescent. All investigated sorts can be characterized by TLC. Botanical differences are clear in TLC; HPLC shows only an indication. Results in TLC have a better reproducibility of retention than in HPLC. Solvent costs and time efforts are less in TLC.
Indian Drugs 34 (8), 433-436 (1997). HPTLC on silica gel with dichloromethane - acetone - methanol - triethylamine 70:40:50:2. Densitometry at 257 nm.
J. Chinese Trad. Patent Med. (Zhongchengyao) 25 (7), 526-529 (2004). TLC on silica gel with benzene - ethyl acetate - methanol - isopropanol - conc. ammonia 20:10:5:5:1. Detection of berberine chloride under UV 365 nm. Identification by standard comparison. Quantification by densitometry at 342 nm. GC of volatile oil and HPLC of cinnamyl aldehyde. Discussion of the optimization of the extraction methods of combined ingredients of the medicine.
