- 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 Chromatogr A, 1624, 461239 (2020). Samples were chemical standards of acetylcholinesterase (AChE) inhibitors (azamethiphos, caffeine, donepezil, galanthamine, methiocarb-sulfoxide, paraoxon-ethyl) and of neurotoxic compounds, as well as drinking or contaminated water samples enriched through solid phase extraction. HPTLC on spherical silica gel (pre-washed twice by 20 min immersion in isopropanol, heated 20 min at 120 °C before and after pre-washing with acetonitrile). First separation (preparative TLC) with automated multiple development (16 steps). Effect-directed analysis for AChE inhibitors by immersion (speed 5 cm/s, time 1 s) into enzyme solution, incubation 5 min at 37 °C and immersion into substrate solution (indoxyl acetate 2 % in methanol); visualization under UV 366 nm. Active zones from untreated layers were eluted through the oval head of a TLC-MS interface to a second plate for a second separation with a panel of other mobile phases. Bands of interest were eluted from the second layer with water through the oval elution head of the TLC-MS interface pump, into a RP18 liquid chromatography guard column, followed by a quadrupole time-of-flight mass spectrometer. Full scan mass spectra (m/z 100–1200) were recorded in negative and positive modes using electrospray ionization (and collision-induced dissociation for MS2). Among the water contaminants, lumichrome (riboflavin photolysis product), paraxanthine and linear alkylbenzene sulfonates were identified as AChE inhibitors.
Molecules, 26 (24), 7683 (2021). Samples were ultrasound-assisted extracts of fruit puree and juice (pre-treated with sulfur dioxide or ascorbic acid) of Ananas comosus (Bromeliaceae) and Mangifera indica (Anacardiaceae). HPTLC on silica gel with toluene – ethyl acetate – methanol – formic acid 120:90:35:3. Detection under white light, UV 254 nm and 366 nm, before and after derivatization by immersion (2 s, 3 cm/s) into anisaldehyde sulfuric acid reagent and diphenylamine aniline reagent, followed by heating at 110 °C for 5 min. Effect-directed analysis using automated immersion: A) for free radical (DPPH•) scavengers; B) for enzymatic inhibition (acetyl-cholinesterase, tyrosinase); C) for activity against Gram-negative (Aliivibrio fischeri bioluminescence assay) or Gram-positive bacteria (Bacillus subtilis bioassay). Active compounds were far more present in puree than in juice extracts, and differences were also seen between cultivars. Ascorbic acid (hRF 37), used as additive for the mango puree, was active as antioxidant and as transiently disruptive for A. fischeri metabolism and bioluminescence.
Chinese J. Hosp. Pharm. (Zhongguo Yoydan Yaoxue Zazhi) 11, 435-437 (1991). TLC of benzoic acid and miconazole nitrate on silica with hexane - chloroform - methanol - diethylamine 42:21:13:5. Quantification by densitometry at 220 nm.
J. Chromatogr. 349, 295-300 (1985). Study on the interaction of the membrane phospholipid, dioleylphosphatidyl choline with 23 nonionic tensides by charge-transfer. Reversed-phase TLC on cellulose with water - ethanol 12:13. Exposure of the chromatogram to iodine vapor. Discussion of the dependence of the lipophilicity of dioleoyl phosphatidyl choline on tenside concentration of eluent.
Chinese J. Chromatogr. (Sepu) 10, 295-297 (1992). Determination of the number of ethylene oxide and its distribution in four oxyethylenated anionic surfactants by TLC and field desorption MS. Comparison of the results obtained by one-dimensional TLC to those obtained by two-dimensional TLC, and of the results obtained by TLC to those obtained by field desorption MS.
Proc. Intern. Symp. on Planar Separations, Planar Chromatography 2001, pp. 241-250. Preparative TLC of b-alkyl-polyethyleneoxy-propionitrile derivatives on silica gel with e.g. perchloroethylene and acetone. Visualization with 2% iodine reagent. IR analysis after removal of the compound-containing sorbent and extraction as KBr tablet or solution.
J. Agric. Food Chem. 34, 1-5 (1986). TLC separation of DHDP (3,3'-bis (1,1-dimethylethyl)-5,5'-dimethoxy-1,1'-biphenyl-2,2'-diol) on silica with dichloromethane - methanol - acetic acid 80:20:1 and hexane - benzene - ether 90:30:3. After cutting the plate into portions, determination of (14C) compounds by liquid scintillation; detection by autoradiography.
