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. Planar Chromatogr. 6, 168-180 (1993). Overview of TLC analysis of benzodiazepines (separation and identification of standards; evaluation in pharmaceutical preparations; evaluation in biological material; densitometry,; spectrophotometry after elution). Short description of drugs, solid phase, mobile phase, detection and comments.
(German). Deutsche Apotheker Zeitung 135, 32-38 (1995). Description of eluents, i.a. improvement of selectivity and separation, eluents from the upper resp. lower phase, difficult compositions of eluents (e.g. ether, chlorinated hydrocarbons), separation distance and time, detection and derivatization, evaluation and documentation, dummary. TLC of carbamazepin, flavonoid-containing dry extracts, theophylline, carbohydrates.
Indian Drugs 34(2), 89-94 (1997). HPTLC of phyllanthus amarus extract on silica with hexane - ethyl acetate 1:1. Densitometry at 260 nm and 409 nm. The evaluation of fingerprints was used to assess the shelf life of the herbal preparation.
Indian Drugs 35 (10), 653-657 (1998). HPTLC on silica with ethyl acetate - methanol 9:1. Quantification by densitometry at 277 nm. Terazosin was used as internal standard. Recovery 99.9 ± 0.77%. A simple and accurate HPTLC method.
J. Chinese Trad. & Herb. Drugs (Zhongcaoyao) 32 (5), 451-452 (2001). TLC on silica gel with 1) chloroform - methanol 9:1, 2) chloroform - methanol - water 7:3:1. Detection by spraying with 10% sulfuric acid in ethanol and heating at 105°C. Identification by finger print technique. Discussion of using the procedure for quality control.
J. Chinese Trad. Patent Med., (Zhongchengyao) 25(5), 363-365 (2003). TLC on silica gel with toluene - ethyl acetate - formic acid 20:10:3. Detection by spraying with 5% AlCl3 in ethanol and heating at 105°C. Identification by finger print technique.
Chromatographia 66 (3-4), 295-296 (2007). HPLC of nitroguanidine and guanidine nitrate on silica gel layers with dioxane – tetrahydrofuran 1:1. Detection under UV 210 nm for guanidine nitrate and 265 nm for nitroguanidine. Quantification by absorbance densitometry using peak area calibration. The method was used for separation and quantification of the compounds for online and off-line quality control of synthesis.
J. Planar Chromatogr. 27, 416-419 (2014). HPTLC of (1) cotinine and (2) trans-3'-hydroxycotinine in urine on RP-18 with acetonitrile - water 4:1. Quantitative determination by absorbance measurement at 260 nm. Linearity was in the range of 65-325 ng/zone (at a low calibration range) and 325-1300 ng/zone (at a high calibration range) for (1) and 62.5-312.5 and 312.5-1250 ng/zone for (2). The intermediate precisions were below 9 % (n=3). The LOD and LOQ were 13 and 38 ng/zone for (1) and 17 and 50 ng/zone for (2), respectively.
