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:

- 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.
GIT Fachz. Lab. Spez. Chrom. 2/96, 126-129 (1996). Combination of conventional TLC, with subsequent color detection and HPTLC, using AMD and densitometry. - HPTLC screening of amines after reductive cleavage of azoic dyes on silica with dichloromethane - acetonitrile 25:3; detection by coupling with (1-naphthyl)-ethylene diammonium dichloride. Confirmation of positive samples by AMD using a 15-step gradient. Quantification by densitometry at 200, 230, and 300 nm. As alternative TLC with diisopropylether - pentane - diethylamine 12:8:1.
TLC and HPLC of cinnamon and its ingredients (eugenol, cumarine, cinnamaldehyd and linalool). There are different sorts (Cinnamomum ceylanicum, Saigon cassia and Cassia korintji) of cinnamon with different ingredients, e.g. Cinnamomum ceylanicum is missing cumarine. TLC on silica with dichloromethane up to 7 cm. The activity of the layer is adjusted with sulfuric acid dilutions - best relative humidity was 40%. Derivatization by anisaldehyde- or vanillin-sulfuric acid reagent and heating at 100-110°C for 10 min. Additionally spraying with potassium hydroxide to make cumarines fluorescent. All investigated sorts can be characterized by TLC. Botanical differences are clear in TLC; HPLC shows only an indication. Results in TLC have a better reproducibility of retention than in HPLC. Solvent costs and time efforts are less in TLC.
J. Chinese Trad. Patent Med. (Zhongchengyao) 18 (3), 13-14 (1996). TLC on silica with isopropanol - acetone - lactic acid (0.1 mol/mL) 2:2:1. Detection by spraying with 10 % sulfuric acid in ethanol and heating at 130°C for 5 min. Quantification by densitometry at 460 nm.
Chinese Anal. Chem. (Fenxi Huaxue) 26, 81-84 (1998). TLC on silica, development twice with 1) chloroform - methanol - acetic acid - acetone - water 35:25:4:14:2, 2) hexane - ether 4:1. Detection by spraying with 10% phosphomolybdic acid in ethanol and heating at 120°C for 10 min, and with Dittmer reagent. Quantitation of phosphatidylcholine (pc), cholesterol (ch), and glycerolipid (gly) by densitometry at 650 nm. Detection limit <0.2 mg/spot. Recovery 104% (n=5) for pc.
Chinese J. Modern Appl. Pharm. (Zhongguo Xiandai Yingyong Yaoxue) 15, 51-52 (1998). TLC on silica gel with benzene - ethyl acetate 9:1. Detection under UV. Quantitation by densitometry at 322 nm. Precision = 1.17% (n=6). Recovery 98.0 ± 0.68% (n=4).
J. Chinese Herb. Med. (Zhongcaoyao) 28, 723-725 (1997). TLC on silica gel by double development with hexane - ethyl acetate - ether - formic acid 100:80:20:1. Detection under UV 254 nm. Precision within plate 1.92% (n=5), plate-to-plate 2.64% (n=5). Recovery 98.10 ± 2.25% (n=5).
CBS 90, 2-4 (2003). HPTLC-AMD on silica gel with a 11-step gradient with chloroform - ethanol - acetone followed by 3 isocratic steps with chloroform for separation of cholesterol, cholesterol sulfate and various ceramide classes. For separation of cholesterol, fatty acids, triacylglycerol, cholesteryl esters, and squalene a 2-step gradient with n-hexane - ethyl acetate followed by an isocratic step with n-hexane. Conditioning between single runs with 4 M acetic acid. Detection by dipping in copper sulfate reagent followed by heating at 150 °C for 20 min. Quantitative determination by absorbance measurement at 546 nm.
CBS 89, 10-11 (2002). HPTLC on silica gel with 1) ethyl acetate - chloroform 1:1 over 30 mm followed by drying at room temperature for 15 min and 2) ethyl acetate - chloroform 9:1 over 50 mm in horizontal development chamber. Detection by dipping in anisaldehyde - sulfuric acid reagent followed by heating at 60 °C for 5 min. Quantitative determination by absorbance measurement at 440 nm. Precision (n=6 at 100 mg/kg feed) is found to be 2.7 %.
