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

60th Indian Pharmaceutical Congress PA-197, (2008) HPTLC of medroxyprogestrone acetate in bulk and injectable dosage form on silica gel with toluene - ethyl acetate - ammonia 800:200:1. Quantitative determination by absorbance measurement at 240 nm. The linearity was in the range of 50-1800 ng/spot. Recovery was 100.1 %. In the stability test (acid, base, peroxide, thermal, photodegradation) the compound was well separated from degradation products. The method was suitable for routine quality control and for monitoring stability.

TLC of testosterone, 5-dehydroandrosterone and androsterone on cyano- and amino- modified precoated silica with hexane - acetone 80:20. Detection by fluorescence at 360 nm after spraying with 5 % perchloric acid in methanol and heating at 110°C for 5 min.
Phytochemical Analysis 4, 76-81 (1993). TLC of fractions issued from an ethyl acetate extract of Mandevilla velutina (Apocynaceae) on silica with hexane - chloroform 1:4. Isolation of a new pregnane type steroid by PTLC on silica with hexane - diisopropyl ether - acetone 4:4:3. Detection with 10% sulfuric acid in methanol, followed by 3% phosphomolybdic acid in methanol.
J. Planar Chromatogr. 26, 395-401 (2013). HPTLC of 17alpha-ethinylestradiol (1), 17beta-estradiol (2) and estrone (3) on silica gel with chloroform - acetone - petroleum 11:4:5. The method was combined with the Yeast Estrogen Screen for the detection of estrogenic effects in sediment extracts of a river. Quantitative determination by absorbance measurement at 320 nm. The hRf values of compounds (1) to (3) were 74, 61 and 84, respectively.LOD and LOQ were calculated for the estrogenic model compound (1): LOD was 0.46 pg without prior development of the TLC plate and 0.48 pg after development, LOQ was 0.8 pg without development and 1.6 pg after development.

(German). Deutsche Apotheker Zeitung 129, 1998 (1989). TLC of ethisterone, norethisterone, mestranole, estradiolbenzoate, ethi- nylestradiole on silica with acetone - chloroform 1:9. Visualization under UV 254 and 366 nm.
J. Planar Chromatogr. 20, 327-330 (2007). TLC of beta-sitosterol on silica gel with toluene - ethyl acetate - glacial acetic acid 15:4:1 with chamber saturation for 30 min. Visualization by spraying with anisaldehyde reagent and heating at 90 °C for 5 min. Densitometric quantitation at 525 nm.
J. Planar Chromatogr. 30, 181-187 (2017). HPTLC of guggulsterones E (1) and Z (2) in a polyherbal formulation containing Commiphora Muku on silica gel with toluene – ethyl acetate 4:1. Quantitative determination by absorbance measurement at 251 nm. The hRF values for (1) and (2) were 34 and 41. Linearity was between 0.2 and 1.2 μg/zone. LOD and LOQ were 43 and 132 ng/zone for (1) and 39 and 120 ng/zone for (2), respectively. The intermediate precision was below 2 % (n=3). Average recovery was 94.4 % for (1) and 97.7 % for (2).
