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. Planar Chromatogr. 11, 311-312 (1998). TLC of 24 carotenoids (i.a. new compounds with 5-hydroxy-3,6-epoxy-b-(7-oxabicyclo[2.2.1]heptyl)-, 3,5,6-trihydroxy-b-, and 6-hydroxy-3,4-didehydro-y-end groups) on silica gel with petroleum ether - acetone 3:2, petroleum ether - tert. butanol 4:1, and methanol - benzene - ethyl acetate 1:15:4. Methanol - benzene - ethyl acetate seemed to be the best mobile phase for the TLC separation of the whole range of oxygenated carotenoids.
J. Planar Chromatogr. 18, 368-371 (2005). TLC of L-ascorbic acid in aqueous extracts of pharmaceutical preparations and pepper juice on silica gel with glacial acetic acid - acetone - methanol - benzene 3:1:4:14, butanol - formic acid - water 200:10:3, and water - glacial acetic acid - ethyl methyl ketone - ethyl acetate 1:2:2:5. Detection under UV 254 nm. Quantitative determination by absorbance measurement at 588 nm after oxidation with iodate.
Journal of Pharmacy Research 4(4), 1197-1198 (2011) Vitamin C contents were estimated in fruit and fruit pulp. HPTLC of vitamin C from methanolic extracts of Pithecellobium dulce pods on silica gel with ethanol - water 2:1. Densitometric quantification at 254 nm. The method was linear in the range of 100-600 ng/band. The method could be employed for quality control of formulation containing the plant as one of the ingredient.
(Analysis of 5-bromo-5-nitro-1,3-dioxane (Bromidox) an antimicrobial agent for cosmetics.) Z. Lebensm. Unters. Forsch. 177, 271-277 (1983). TLC of 5- bromo-5-nitro-1 ,3-dioxane on silica with acetone and on silica-cellulose with ethyl acetate - methanol -10 % N3 65:30:5. Detection by UV 254 nm. Detection also with AgNO3 - H2O2 - reagent and by UV. Detection limit 5 -10 mg.
Elution with ethanol - hexane 1:10. Quantitatiom by specrophotometry. Also TLC-densitometry for alpha- beta-carotene.
Chinese J. Chromatogr.(Sepu) 7, 243-245 (1989). TLC of vitamins B1, B2 and B6 on silica with chloroform - ethanol - acetone - NH3 2:2:2:1. Quantification by fluorescence densitometry with excitation at 330 or 360 nm. Detection limits 10 ng for B1 and B2, 40 ng for B6.
Chinese J. Herb Med. (Zhongcaoyao) 24, 652-653 (1993). TLC of vitamin E on silica with petrol ether (60-90°) - ethyl acetate 95:5. Quantification by densitometry (absorbance) at 280 nm. Discussion of interference with other impurities.
J. Agric. Food Chem. 46, 731-736 (1998). New procedure TLC of alkoxy-substituted benzaldoxims, e.g. 3-methoxy-, 3,4-dimethoxy-, 3,4-dimethylenedioxy-4-ethoxybenzaldoxim N-O-alkyl ethers on silica gel with n-hexane - acetone 3:1. Visualization either by exposure to iodine vapors or by spraying with 2,4-dinitrophenylhydrazine solution. Determination of lipophilicity by finding out the Rf values on RP-TLC using silica gel impregnated with paraffin in n-hexane 1:9 and acetone - water 3:2. Detection by spraying with 2,4-dinitrophenylhydrazine solution.
