Nematicidal activities of acetylene compounds from Coreopsis lanceolata L.
1-Phenylhepta-1,3,5-triyne (1), 5-phenyl-2-(1'-propynyl)-thiophene (2), and 2-(3'-acetoxy-1'-propynyl)-5-phenylthiophene (3) were isolated from Coreopsis lanceolata L., and their structures identified by spectroscopic methods. Compounds 1 and 2 showed effective nematicidal activities against Bursaphelenchus xylophilus and Caenorhabditis elegans, but had hardly any effect against Pratylenchus pe...
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 کاملChalcones from the flowers of Coreopsis lanceolata and their in vitro antioxidative activity.
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 chalco...
متن کاملEffects of Bunch Rot (Botrytis cinerea) and Powdery Mildew (Erysiphe necator) Fungal Diseases on Wine Aroma
This study aimed to characterize the effects of bunch rot and powdery mildew on the primary quality parameter of wine, the aroma. The influence of these fungal diseases was studied by comparative Aroma Extract Dilution Analyses (AEDA) and sensory tests. The effect of bunch rot was investigated on three grape varieties, namely White Riesling, Red Riesling and Gewürztraminer and that of powdery m...
