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. AOAC Int. 82, 231-238 (1999). HPTLC of deramciclane and metabolites on silica gel using a stepwise gradient OPLC separation with chloroform - acetonitrile 2:4 (A) and n-butanol - acetic acid - water 4:1:1 (B). Detection of radioactive compounds by rapid digital autoradiography; Visualization under UV. Videodensitometry.
59th Indian Pharmaceutical congress E-243, 283, (2007). HPTLC of Bergenia ciliata leaves and rhizomes successively (Soxhlet) extracted with petroleum ether (40-60°C), chloroform, n-butanol, and ethyl acetate, on silica gel with ethyl acetate - glacial acetic acid - formic acid - water 128:50:50:122. Evaluation under UV 254 nm.
J. Chromatogr. Sci. 46 (4), 320-324 (2008). HPTLC of jasmonic acid (extracted from Lasiodiplodia theobromae with ethyl acetate) on silica gel with isopropanol - ammonia - water 10:1:1. Quantification by densitometry at 295 nm in absorbance mode. The limit of detection and quantification was 1 µg and 80 µg, respectively. The method is useful for high sample throughput, e.g. for routine analysis of jasmonic acid in perfumery industries.
Anal. Chim. Acta 599 (2), 302-309 (2007). HPTLC of minocycline on silica gel (impregnated with a 10 % (w/v) solution of disodium ethylene diaminetetraacetic acid (EDTA) with a pH of 9.0) with methanol - acetonitrile - isopropyl alcohol - water 10:8:1:1. Quantitative determination by absorbance measurement at 345 nm. The limit of detection was 3.7 ng/spot, recovery was 99.2 - 100.2 %, and precision was good with a %RSD of 0.4 %. The method was able to separate all degradation products (produced by acidic and basic degradation, oxidation and photodegradation) from the pure drug.
Chinese J. Pharm. Anal. 28 (4), 608-610 (2008). TLC of hyperoside in the raw extract of Hypericum perforatum on silica gel with petroleum ether (60-90 °C) – ethyl acetate – methanol 1:4:2. Detection under daylight. Quantification by densitometry at 591 nm. Linearity was given between 0.1 and 14.4 µg/spot (r2 = 0.9892), recovery was between 96.4 and 100.1 %.
Acta Chromatographica 22 (3), 433-443 (2010). HPTLC on silica gel with ethyl acetate – methanol - acetic acid 13:2:1. The hRf values were 46 and 78 for nebivolol hydrochloride and hydrochlorothiazide, respectively. Detection and quantification by densitometry at 280 and 270 nm for nebivolol hydrochloride and hydrochlorothiazide, respectively. The drugs were subjected to hydrolysis under acidic, basic, and neutral conditions, oxidation, heat, and photolysis as stress conditions. The drug showed degradation when subjected to oxidative stress and acidic conditions, which also affected the tablet sample substantially. However there was no interference of the drug peak by any of the degradation products. The method was therefore applied for stability testing of these drugs during stability studies.
J. Strait Pharm. 24 (5), 36-38 (2012). Glucosamine sulfate is a kind of glycosaminoglycan, which, as a medicine, is able to stimulate cartilage cells, to supplement the cartilage matrix and to inhibit matrix metalloproteinase expression, thus to promote the repair of cartilage. For better quality control of the medicine a method is presented for the analysis of the related substances in glucosamine sulfate potassium chloride. TLC on silica gel with dichloromethane – methanol – ammonia 2:2:1, detection by exposure to iodine vapors for 30 min and evaluation in daylight. The LOD was 25 µg/mL. Investigation of the stability of the medicines by analysis of a sample submitted to typical stress conditions such as acid, alkali, water bath, hydrogen peroxide, high temperature and UV light. Degradation occurred only for the samples treated with alkali and in the water bath.
CBS 116, 9-10 (2016). HPTLC of herbal slimming drugs and the standard orlistat on silica gel with toluene – ethyl acetate 4:1 with chamber saturation (with filter paper) to the migration distance of 70 mm. Detection by dipping in phosphomolybdic acid reagent (5 g in 100 mL ethanol) and heating at 110 °C for 5 min. Evaluation under UV 254 nm, 366 nm and white light. Quantitative determination by absorbance measurement at 195 nm before derivatization to detect illegally added orlistat in the herbal drugs. The LOD of orlistat standard was 70 ng/band.
