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
Registered users can create a tailor made PDF of selected articles throughout CCBS search – simply use the cart icon on the right hand of each abstract to create your individual selection of abstracts. You can export your saved items to PDF by clicking the download icon.

Chinese J. Trad. Pat. Med. (Zhongchengyao) 27(2), 167-169 (2005). TLC on silica gel with 1) ethyl acetate - methyl ethyl ketone - formic acid - water 10:1:1:1; 2) chloroform - methanol 20:1; 3) chloroform - formic acid - water 13:7:2.

Validation of the method by investigation of linearity (1.12 µg - 5.60 µg, r = 0.999); precision (RSD = 1.63 %, n= 5 within plate and RSD = 2.3 % plate to plate); reproducibility of five time assay towards the same sample (RSD = 3.12 %); standard addition recovery (97.69 %, RSD = 2.10 %, n = 5). The results for three real life samples are given.
Chinese J. Trad. Pat. Med. (Zhongchengyao) 26 (9), app.19-20 (2004). HPTLC on silica gel with petroleum ether (30 - 60 ºC) - formic acetate - formic acid 15:5:1, at 11 ºC and humidity of 40 %. Detection by exposing to ammonia vapors. Identification by fingerprint technique and comparison with the standards.
J. Chinese Trad. Patent Med. (Zhongchengyao) 27(5), 526-529 (2005). TLC of the extracts on silica gel with 1) ethyl acetate - formic acid - water 10:1:2; 2) cyclohexane - chloroform - methanol 10:6:1. Detection 1) by spraying with 10 % H2SO4 in ethanol followed by heating at 105 ºC until the spots are visualized; 2) by exposing to iodine vapor and inspection under UV 365 nm. Identification by fingerprint technique. Monitoring of the dosage limit of aconitine in the medicine by comparison with the standard. Quantification of tetrahydropalmatine by HPLC. The results are given for 10 batches of real life samples.
J. Planar Chromatogr. 19, 195-199 (2006). HPTLC of scopoletin on silica gel with toluene - diethyl ether 1:1, saturated with 10 % glacial acetic acid, in a twin-trough chamber saturated with mobile phase for 45 min. Evaluation by densitometry at 366 nm. The method was validated for linearity, accuracy, interday and intraday precision, specificity, repeatability of measurement of peak area, and repeatability of sample application. Limit of detection was 50 ng/spot.
