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 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.
J. Planar Chromatogr. 20, 331-334 (2007). HPTLC of tizoxanide (with nitazoxanide as internal standard) on silica gel prewashed with methanol in a twin-trough chamber with toluene - ethyl acetate - acetic acid 62:134:4. UV detection and quantitation at 313 nm for the internal standard and at 410 nm for tizoxanide.
(Determination of paracetamol in serum by HPTLC.) Fresenius Z. Anal. Chem. 321, 601-602 (1985). Chromatography on silica with hexane - acetone - ethanol 6:3:1. Densitometry by absorbance at 250 nm. Determination limit 250 ng/ml serum.
59th Indian Pharmaceutical congress F-10, 392, (2007). HPTLC of olmesartan medoxomil and hydrochlorothiazide on silica gel with acetonitrile - chloroform - glacial acetic acid 14:4:1 with chamber saturation for 30 min. Densitometric evaluation at 254 nm. Linearity was between 480 and 900 ng/zone for olmesartan and 150 and 600 ng/zone for hydrochlorothiazide. Recovery was 99.7 - 100.4 % . The method can be used for routine quality control of formulations.
J. Chromatogr. 427, 121-130 (1988). TLC of cyclophosphamide and its metabolites on silica with chloroform - ethanol - acetic acid 100:20:1. Detection by spraying with 5% 4- (4-nitrobenzyl)pyridine in acetone-0. 2 M acetate buffer pH 4. 6 8:2 and heating at 130-150°C for 5-15 min. and dipping in 3% methanolic potassium hydroxide. Photography of the chromatogram within 10 seconds. Quantification by densitometry. Detection limit, 0. 5-1 µg/L. The calibration curves were found linear over a range of 1-250 µg/mL.
