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.
J. Chinese Herb Med. (Zhongcaoyao) 23, 575-576 (1992). TLC of liensinine on silica with chloroform - diethylamine 9:1. Quantification by densitometry at 223 nm.
Chinese J. Pharm. Anal. (Yaowu Fenxi Zazhi) 12, 237-238 (1992). TLC of glycyrrhizic acid on silica with butanol - acetic acid - water 6:1:3. Quantification by densitometry at 255 nm.
J. Planar Chromatogr. 6, 129-137 (1993). HPTLC of vanilla extracts and reference substances on silica with chloroform - ethyl acetate - propan-1-ol 96:2:2 or 94:2:2; detection by postchromatographic derivatization with 2,4-DNPH in 25 mL 95% ethanol and 25 mL of 85% orthophosphoric acid for about 5 sec. Quantification by densitometry (absorbance at 280 nm). A simple method with a high sample throughput.
J. Liquid Chromatogr. 15, 2959-2966 (1992). TLC of gangliosides on silica with chloroform - methanol - 25% aqueous CaCl2 11:9:2. Detection by spraying with sulfuric acid 50%. Quantification by densitometry.
Biomed. Chromatogr. 6, 141-142 (1992). TLC of theophylline, diprophylline and proxyphylline on silica with chloroform - ethanol - formic acid 19:1:2. Detection under UV 254 nm. Quantification by densitometry at 275 nm. Second degree polynomial function over the range 40 - 200 ng for theophylline, 60 - 300 ng for diprophylline and proxyphylline.
uralensis, preparations by thin-layer chromatography.) (Chinese). J. Chinese Herb Med. (Zhongcaoyao) 24, 296-297 (1993). TLC of glycyrrhizic acid on silica with butanol - acetic acid - water 4:1:2. Quantification by densitometry at 254 nm.
Chromatographia 35, 430-434 (1993). TLC of flavonoids on cellulose, polyamide, and silica with different solvent systems. Detection by spraying with 1% methanolic NaOH solution, saturated methanolic H3BO3 solution, 1% methanolic sodium acetate solution, and 5% methanolic AlCl3 solution. Identification by measuring the spectra from 200 to 450 nm. Reasonable spectra can be obtained in-situ with as little as 100 ng sample.

Detection by spraying with 0.2% ninhydrin in ethanol and heating at 105 °C for 10 min. Quantification by densitometry at 254 nm, 325 nm before spraying, and at 510 nm after spraying. R.S.D., 1.7 - 2.3%.
