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:

Pharmacogn. Mag. 14, 45-51 (2018). HPTLC of stigmasterol in Monochoria vaginalis and Monochoria hastata on silica gel with chloroform – methanol 4:1. Detection by spraying with anisaldehyde-sulfuric acid reagent, followed by heating at 105 °C for 5 min. Quantitative determination by absorbance measurement at 540 nm. The hRF value for stigmasterol was 30. Linearity was between 1000 and 5000 ng/zone. LOD and LOQ were 80 and 200 ng/zone. The intermediate precision was <3 % (n=3). Average recovery was 99.8 %.
J. Biochem. (Tokyo) 99, 771-775 (1986). Reversed-phase TLC of cholestanol after conversion to alpha and beta -epoxides with m-chloroperbenzoic acid. Detection by spraying with phosphomolybdic acid. Quantification by densitometry. The calibration curves were linear 100-1000 ng. Correlation among TLC, GC/MS, and GC methods was 1:1:1. TLC method is useful for primary diagnostic screening of CTX.
Phytochemistry 28, 143-154 (1989). TLC of desmethyl sterols on silica with butanol - hexane 2:8. Detection by spraying with 1% 2',7'-dichlorofluorescein in ethanol and visualization under long wave UV.
J. Chromatogr. 614, 315-323 (1993). TLC of diethylstilbestrol and zeranol on silica with dichloromethane - methanol - 2-propanol 97:1:2. Visualization with iodine - starch, or by spraying with 0.05% aqueous solution of diazonium dyes, and exposure to NH3 vapor for 30 sec and heating at 80 °C for 2 min.
Dtsch. Apoth. Ztg. 139, 835-836 (1999). TLC of ethinyl estradiol (using methyltestosterone, norethisterone, progesterone, estradiol benzoate, testosterone propionate and mestranol as reference substances) on silica gel with toluene - ethyl acetate 7:3; without chamber saturation). The plate is left for 15 min in the air after application. Detection under UV 254 nm (ethinyl estradiol can not be recognized!), and after spraying with 20% ethanolic sulfuric acid, heating at 110°C for 5 min under daylight and UV 360 nm. Approved procedure for identity and quality test.
II. One-dimensional and two-dimensional TLC. J. Liq. Chrom. Rel. Technol. 27, 2031-2038 (2004). TLC of 7 bile acids (chenodeoxycholic, deoxycholic, cholic, glycocholic, lithocholic, glycodeoxycholic, and glycolithocholic acid) on silica gel with n-hexane - ethyl acetate - acetic acid 5:4:1 in the first dimension and chloroform - n-butanol - acetic acid - water 1:16:1:1 in the second dimension. Detection by spraying with 10 % sulfuric acid followed by heating at 120 °C for 20 min. The 2D technique allowed the complete separation of all the bile acids studied.
Trends Anal. Chem. 82, 250-267 (2016). This review describes the application of capillary electrochromatography in food safety and food quality, from the first application in 1997, including the use of TLC for sample preparation in the analysis of sterols in the oils of sunflower, canola rice bran, olive (extra virgin), soybean, corn, peanut, grapeseed, and hazelnut.
leaves. J. Planar Chromatogr. 31, 377-381 (2018). HPTLC of ursolic acid and β-sitosterol in the leaves of Paederia foetida on silica gel with toluene ‒ ethyl acetate ‒ formic acid 80:20:1. Detection by spraying with anisaldehyde–sulfuric acid reagent, followed by heating at 110 °C for 1 min. Quantitative determination by absorbance measurement at 550 nm. The hRF values for (1) and (2) were 22 and 38, respectively. Linearity was between 100 and 500 ng for (1) and (2). LOD and LOQ were 40 and 121 ng for (1) and 50 and 152 ng for (2). The intermediate precision was <2 % (n=3). Recovery ranged from 97.2 % to 99.2 % for (1) and 98.0 % to 99.2 % for (2).
