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:

J. Planar Chromatogr. 19, 32-41 (2006). TLC of 11 new derivatives of 1,2,4-triazole and of 18 new derivatives of thiosemicarbazide on RP18 with mixtures of methanol, acetonitrile, and water. Amounts of organic modifiers were in the range of 20-70 % in 10 % increments. After development in horizontal DS chambers and drying, the plates were visualized under UV light at 254 nm.
Abstract GP-74 IPC (2005). HPTLC of etoricoxib in tablets on silica gel with toluene - 1,4 dioxane - methanol 17:2:1. Quantitative determination by absorbance measurement at 235 nm. Linearity range was 500-1500 ng/spot. For stability studies the sample was subjected to acid and alkali hydrolysis, thermal, oxidaline and photo degradation. The peaks of all the degraded products were well resolved with significant different Rf values. The method was validated for different parameters and found suitable for routine quality control.
Chem. Pharm. Bull. 53, 691-693 (2005). HPTLC of trans-resveratrol in the roots of Polygonum cuspidatum and in dosage forms on silica gel with chloroform – ethyl acetate – formic acid 25:10:1. Quantitative determination by absorbance measurement at 313 nm. Linearity of determination of trans-resveratrol is between 0.5 and 3.0 µg with a correlation coefficient of 0.9989. LOD is 9 ng, and LOQ is 27 ng. The average percentage recovery is 99.9 - 100.7 %.
J. AOAC Int. 89, 1300-1304 (2006). TLC of 27 substandard drugs on silica gel with appropriate mobile phases. Routine Minilab (developed by the German Pharma Health Fund) test procedures to screen product quality and a proficiency testing program to determine the competency of health inspectors and reliability of results were established. Although the TLC screening methods provide a rapid means for drug quality assessment, they need to be put in the hands of competent users.
J. Liq. Chromatogr. & Relat. Technol. 29, 2753-2765 (2006). TLC of tadalafil [6R,12aR)-2,3,6,7,12a-hexahydro-2-methyl-6-[3,4-(methylenedioxy)phenyl]pyrazino-[1’,2’:1,6]pyrido[3,4-b]indole-1,4-dione] on silica gel with n-hexane - ethyl acetate - methanol 4:3:1. Quantitative determination by absorbance measurement at 285 nm.
Indian Drug 44 (2), 122-127 (2007). HPTLC of ayurvedic medicated oil on silica gel in a twin-trough chamber with ethyl acetate - toulene 1:9 for fingerprint analysis, and ethyl acetate - methanol - water 200:27:20 for quantitative determination of colchicine.
J. Liq. Chromatogr. & Relat. Technol. 29, 2257-2270 (2006). HPTLC of 20 methyl-thiazole-oxadiazoline derivatives on RP 18 with mixtures of methanol - water with varying contents from 45 - 70 % in 5 % steps. Examination after drying under UV light at 254 nm.
J. Planar Chromatogr. 20, 335-339 (2007). TLC of etoricoxib (rofecoxib as internal standard) on silica gel in a filter-paper-lined twin-trough chamber previously saturated with mobile phase vapor for 30 min with toluene - 1,4-dioxane - methanol 17:2:1. Densitometric analysis of etoricoxib was performed in absorbance mode at 235 nm. The limits of detection and quantitation were 30 and 100 ng/zone, respectively.
