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. Liq. Chrom. Rel. Technol. 27, 2039-2045 (2004). HPTLC of cholesteryl oleate, methyl oleate, triolein, oleic acid, and cholesterol on pre-washed silica gel with petroleum ether - diethyl ether - glacial acetic acid 80:20:1 in a twin-trough chamber with saturation. Detection with phosphomolybdic acid reagent. Quantitative determination at 610 nm.
Indian Drugs 41 (8), 482-487 (2004). HPTLC on silica gel with toluene - acetone - ammonia 50:50:1. Quantitative determination by absorbance measurement at 315 nm. The method was validated in terms of linearity (300-1000 ng/spot), precision, accuracy, and specificity. For the content uniformity test the tizanidine hydrochloride content of 10 individual tablet units of two market formulations was determined after extracting with methanol. Both formulations compiled with the USP specification. The proposed content uniformity allows the parallel analysis of ten tablets on a single plate and provides a faster and cost-effective quality control tool for routine analysis. A simple, sensitive HPTLC content uniformity test was developed and validated for the analysis of tizanidine hydrochloride in its commercial single component tablet formulations (2 mg/tablet).
J. Planar Chromatogr. 17, 286-289 (2004). HPTLC of isoquercitrin, avicularin, rutin, apigenin 7-glucoside, naringin, and hesperidin on silica gel with ethyl acetate - methanol - formic acid 90:10:1. Detection under UV light at 254 nm and by spraying with 1 % methanolic diphenylboric acid beta-ethylamine ester, followed by spraying with 5 % ethanolic polyethylene glycol 4000. Quantitative determination by densitometry at 254 nm. Report of the possibilities and advantages of HPTLC for investigation of hydrolysis.
56th IPC 2004, Abstract No. GP-46. Stability indicating HPTLC determination of cefuroxime axetil in bulk drug and in formulations on silica gel with chloroform - methanol 23:2. Quantitative determination by scanning at 278 nm. The sample was subjected to acidic, and alkali hydrolysis, oxidation and photo degradation. The degraded products were well separated. The method was validated for accuracy, precision, linearity, specificity, ruggedness, and recovery (98 - 100 %).
56th IPC 2004, Abstract No. GP-48. HPTLC of rabeprazole sodium in tablet dosage form on silica gel with ethyl acetate - methanol 9:1. Optimization of experimental parameters such as bandwidth, chamber saturation time, solvent front migration, and mobile phase composition. Quantitative determination by scanning at 260 nm. The Rf value was 0.59. The method was linear with a correlation coefficient of 0.99, recovery was 98.81 %.
J. AOAC Int. 88, 1537-1543 (2005). HPTLC of caffeine, acetaminophen and acetylsalicylic acid on silica gel with concentration zones using methanol - ethyl acetate 3:17. UV absorption densitometry is used for the quantitative determination of caffeine. Precision, accuracy, linearity, limits of detection and quantitation, and selectivity were validated. - A comparative study using a caffeine standard solution and a multicomponent analgesic tablet solution containing caffeine, acetaminophen, and acetylsalicylic acid showed that manual application on the concentration zone, and instrumental application on the silica gel gave quite similar results in terms of number of theoretical plates, resolution, limit of detection, and linearity.
J. Planar Chromatogr. 18, 147-150 (2005). HPTLC of acteoside from leaves of Plantago lanceolata on silica gel with ethyl acetate - formic acid - water 18:1:1. Quantitative determination by densitometry at 334 nm. Intra-day and inter-day RSD were 0.58 and 2.0 %, respectively. Instrumental precision and repeatability of the method (CV) were found to be 0.62 and 1.5 %, respectively. The average recovery was 102.3 %.
J. Planar Chromatogr. 18, 28-33 (2005). HPTLC and TLC of four carbamate residues (pirimicarb, methomyl, carbofuran, carbaryl) in vegetables on silica gel (prewashed with chloroform - methanol 1:1 followed by drying at 110 °C for 30 min) with system I (two fold development with first toluene - acetone 4:1, and second dichloromethane - acetone 4:1), and system II (two fold development with first ethyl acetate - petroleum ether 3:2, and second chloroform - petroleum ether 9:1). Quantitative determination by densitometric scanning at 254 and 366 nm.
