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.
Application to analysis of flavonoids in Scutellariae radix. Chromatographia 35, 281-284 (1993). HPTLC of flavonoids (baicalin, baicalein, wogonin, oroxylin A) on silica treated with phenyl-groups, with methanol - 1/15 M phosphate buffer 60:40, 90:10, and on RP-18 silica with methanol - 1/15 M phosphate buffer 90:10. Quantification by densitometry at 280 nm. Discussion of the retention and selectivity of the flavonoids in the different systems.
Chinese J. Instr. Anal. (Fenxiceshixuebao) 14, 62-65 (1995). TLC of rutin on silica with ethyl acetate methanol - water 8:1:1. Detection under UV 254 nm. Quantification by densitometry at 355 nm. Detection limit 5.0 ng.
(Hawthorn-Flavonoid pattern and TLC identity test.) Dtsch. Apoth. Ztg. 136, 15 - 20 (1996). HPTLC separation of flavonoids (i.a. vitexine, spiraeoside, luteolin-7-O-glucoside, acetylvitexine-rhamnoside, hyperoside, and chlorogenic acid, vitexine rhamnoside, rutin, chlorophyll) on silica with one- or two-dimensional development with ethyl acetate - acetic acid - water 8:1:1, ethyl acetate - MEK - formic acid - acetic acid - water 50:30:7:3:10, ethyl acetate - methanol - NH3 25% 4:4:1, or ethyl acetate - pyridine - water - methanol 16:4:2:1. Detection of flavonoids by dipping in diphenylboryloxyethylamine (0.5%) in ethyl acetate, drying, dipping in Macrogol 400 (5%) in dichloromethane, drying and treatment with 25% NH3.
J. of Natural Products 61, 706-708 (1998). Isolation of novel flavonoid glycosides by prep. TLC on silica gel with the lower layer of chloroform - methanol - water 13:7:2. Final purification by prep. TLC with chloroform - methanol - water 80:20:3. Detection under UV 254 nm.
J. Planar Chromatogr. 12, 26-29 (1999). TLC of rutin on silica gel with ethyl acetate - formic acid - water 8:1:1, chamber saturation. Quantitation after drying by densitometry at 260 nm in reflectance mode, also at 440 nm after spraying with a 1% methanolic solution of 2-aminoethyldiphenylborinate.
Chromatographia 51, 473-477 (2000). Determination of retention-mobile phase composition relationships for 18 flavonoids chromatographed with non-aqueous systems of the type silica-diluent + polar modifier (S). Discussion of the slopes of the plots depending on the molecular structures of the solutes, primarily on the number of hydroxyl groups, and the selectivities and sequences depending on the diluent and modifier applied, with plots of Rm against [S] approximately linear.
J. Liq. Chrom. & Rel. Technol. 24, 1171-1179 (2001). TLC of genkwanin, tectochrysin, galangin, apigenin, pilloin, chrysin, kaempferol, pinocembrin, 5-hydroxy-4',7-dimethoxyflavone, and pinostrobin chalcone on silica gel with hexane - dichloromethane and dichloromethane - ethyl acetate in different proportions. Visualization under UV 254 and 366 nm and in day light after spraying with 1% methanolic iron(III) chloride solution or 1% methanolic aluminium chloride solution.
Proc. Intern. Symp. on Planar Separations Plan. Chrom. 305-307 (2003). TLC of flavonoids (7-O-glucoside luteolin, 7-O-glucoside apigenine, 5'-O-glucoside tricetin, 3-O-rhamnoside quercetin, 3-O-rhamnoside kaempferol, luteolin, quercetin, kaempferol, isoginkgetin, ginkgetin) on silica gel in a sandwich chamber, in a Personal OPLC chamber, and by planar electrochromatography method with 11 monocomponent, 8 binary phases in different concentration, and ternary and quaternary mobile phases. The best separation of flavonoids, biflavones, aglycones, glycosides was obtained with ethanol - ethyl acetate -dioxane - hexane (as solvent strength modifier).
