Chalcones from the flowers of Coreopsis lanceolata and their in vitro antioxidative activity.

چکیده
Three new chalcones, 3,2'-dihydroxy-4,3'-dimethoxychalcone-4'-glucoside (1), 4'-O-(2'''-O-caffeoyl)2',3',3,4-tetrahydroxychalcone (2), and 2',4',3-trihydroxy-3',4-dimethoxychalcone (3), along with five known phenolics, were isolated from Coreopsis lanceolata flowers. The structures of the new compounds were elucidated by extensive spectroscopic methods including NMR and MS. The three new chalcones showed a good in vitro HepG2 cell protecting effect against tert-butylhydroperoxide-induced oxidative stress.

متن کاملChemical constituents of Coreopsis lanceolata L. and their physiological activities.
Petals from Coreopsis lanceolata L. were extracted in methanol and subjected to solvent-solvent partitioning to yield four fractions: hexane, diethyl ether, ethyl acetate, and aqueous. These fractions were screened using a 1,1-diphenyl-2-picrylhydrazyl radical scavenging assay and an active oxygen inhibition assay. The ethyl acetate extract contained the highest level of active components. Four...

متن کاملSynthesis and in vitro Antibacterial Activity of Some Novel 2-Amino-4, 6-D Derivatives
Heterocyclic systems are one of the most important classes of organic compounds present in nature or synthesized in laboratory. These compounds posses an array of biological activities and are employed in the treatment of commonly occurring diseases. Keeping this in view, some new 2-amino-4,6-diarylpyrimidine from chalcones were synthesized. Eight novel 2-amino-4,6-diarylpyrimidine derivatives ...
