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

Abstract No. F-269, 61st IPC (2009). HPTLC of hydrochlorothiazide and irbesartan on silica gel with acetonitrile - chloroform 5:6. The hRf value was 27 and 45 for irbesartan and hydrochlorothiazide, respectively. Quantitative determination by absorbance measurement at 270 nm. The sample was exposed to different stress conditions (acid, alkali, oxidative, photodegradation, thermal). Neither of the compounds showed degradation under thermal and photodegradation conditions, but both compounds showed significant degradation under acid, alkali and hydrolytic conditions. Degraded products were well resolved from the parent compounds.
Abstract No. 9274, IHCB (2009). HPTLC of harmalin from ethanolic leaf extracts of Passiflora edulis on silica gel with ethyl acetate - acetic acid - formic acid - water 100:11:11:27. The hRf value of harmalin was 39. The method was linear in the range of 200-1600 ng/spot, recovery was 98.4-99.2 %.
J. AOAC Int. 92, 1373-1381 (2009). TLC of rabeprazole sodium and its degradation products on silica gel with isopropanol - 30 % ammonia 40:1 with chamber saturation. Quantitative determination by absorbance measurement at 284 nm.
60th Indian Pharmaceutical Congress PG-246 (2008). HPTLC of biomarkers such as curcumin, charantin, and swertiamarin in some polyherbal formulations on silica gel with benzene - methanol 4:1 (for charantin), chloroform - methanol - formic acid 74:4:1 (for curcumin), and ethyl acetate - methanol - water 77:15:5 (for swertiamarin). Quantitative determination by absorbance measurement at 536 for charantin (hRf value 33), 425 nm for curcumin (hRf value 89), and 238 nm for swertiamarin (hRf value 54).
J. Planar Chromatogr. 22, 381-384 (2009). TLC of aloin in commercial Ayurvedic preparations on silica gel (prewashed with methanol) with ethyl acetate - methanol - water 50:7:2 in a twin trough chamber with chamber saturation for 5-7 min at 30 +/- 4 °C and a relative humidity of 57 +/- 3 %. Quantitative determination by absorbance measurement at 360 nm. The limit of detection and quantification was 10 and 20 ng/band, respectively.
60th Indian Pharmaceutical Congress PA-208 (2008). TLC of aspirin and clopidogrel bisulphate on silica gel with carbon tetrachloride - acetone 5:2. The hRf value of aspirin was 15 and of clopidogrel bisulphate 80. Quantitative determination by absorbance measurement at 220 nm. The method was linear in the range of 2-6 µg/spot for aspirin and 3-6 µg/spot for clopidogrel.
Abstract No. F-365, 61st IPC (2009). HPTLC of rivastigmine hydrogen tartrate on silica gel with methanol - 25 % ammonia - acetic acid 200:7:2. The hRf value was 54. Quantitative determination by absorbance measurement at 215 nm. The method was linear in the range of 1-10 µg/band.
J. Planar Chromatogr. 23, 50-55 (2010). HPTLC of andrographolide on silica gel with chloroform - methanol - ethyl acetate 12:3:2 in a twin-trough chamber previously saturated for 15 min. Quantitative determination by absorbance measurement at 223 nm. The relative standard deviation of intra-day and inter-day analysis was in the range of 0.56-1.33 %. Lineartiy was given between 200-700 ng/band; the correlation coefficient was 0.9998 and the RSD 0.97 %. The limits of detection and quantification were 60 and 150 ng/band. Average recovery was 98.8 +- 0.41 %.
