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.
L. (German). Fat Sci. Technol. 97, 33-37 (1995). TLC of alkaloids (i. a. retrorsine, monocrotaline) on silica with acetone or chloroform - methanol - NH3 80:20:1. Detection by spraying with solution 1) hydrogen peroxide 36% - diethyleneglycoldimethylether - acetic acid anhydride 1:1:2, 2) acetic acid anhydride - petrol ether (60-80 °) 1:4, and 3) 0.5 g dimethylaminobenzaldehyde in 35 mL ethanol and 15 mL diethyleneglycoldimethylether, immediately before use add 1 mL hydrochloric acid 38%. Drying of the plate for 5 - 10 min at 160 °C between the spraying steps. Quantification visually or by densitometry at 550 nm. A new simple and sensitive TLC procedure.
Phytochemistry 44, 971-973 (1997). Isolation of macrocyclic lactam alkaloids by prep. TLC on silica with ethyl acetate - methanol 4:1 or toluene - 96% ethanol 9:1. Detection under UV 254 nm or with Dragendorff's reagent. Quantification by densitometry after two-fold development with toluene - ethanol at 254 nm.
J. Chinese Trad. Patent Med. (Zhongchengyao) 20 (5), 13-14 (1998). TLC on silica gel with toluene - acetone - ethanol - NH3 20:25:3:5. Quantitation by densitometry at 254 nm. Precision = 1.87% (n=5) within plate and 2.41% (n=5) plate-to-plate. Recovery = 97.12 ± 1.49% (n=5).
by column and thin-layer chromatography. Chromatographia 50, 52-56 (1999). TLC on silica gel with a mobile phase of mixing a constant volume of acetate buffer and various volumes of methanol and redistilled water. Detection under UV 366 nm or by spraying with potassium iodoplatinate reagent and densitometry at 280 nm. Also column chromatography. Investigation of relationship between the logarithm of the retention factors K of the alkaloids and volume fractions of methanol at pH 6, which was linear for volume fraction in range of 0.1 to 0.4. Estimation of the value of the retention factor for a alkaloid in pure buffer and then using the maximum volume of alkaloid extract on micropreparative column filled with silica gel.
Planta med. 65, 164-166 (1999). TLC of aucubin B, harpagide and harpagoside on silica gel with ethyl acetate - methanol 4:1. Detection by spraying with a solution of anisaldehyde - sulfuric acid - acetic acid 1:2:100 followed by heating.

J. Planar Chromatogr. 16, 293-297 (2003). TLC and HPTLC of narceine, morphine, codeine, thebaine, papaverine and narcotine on silica gel with concentration zone with toluene - acetone - ethyl acetate - NH3 (25%) 20:20:3:1 and toluene - acetone - ethanol - NH3 20:20:3:1, respectively. Detection by spraying with Dragendorff's reagent with sodium nitrite or by treatment with formaldehyde-sulfuric acid reagent (Marquis's reagent) and densitometry at 600 nm. Evaluation by densitometry at 520 nm. Simple and quick procedure.
