Two selected examples of PIXE microanalysis in ecophysiology have been shown. Studies of heavy metal distribution in mycorrhizal and nonmycorrhizal roots of Plantago lanceolata showed different mechanisms in filtering of Zn/Pb and Fe/Mn, both enabling plants to cope with metals present in the environment. Studies of the mechanism used by the beetle Chrysolina pardalina to eliminate excessive am...
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...
Codonopsis lanceolata (Campanulaceae) have been traditionally used to treat lung inflammatory diseases, such as asthma, tonsillitis, and pharyngitis. The present study was performed to evaluate the cognitive-enhancing effects of steamed and fermented C. lanceolata in scopolamine-induced memory impairments in mice. Cognitive abilities were determined by the Morris water maze and passive avoidanc...
Addition of iron oxides, lime, clay minerals and other substances can be used to decrease the plant availability toxic heavy metals such as Pb, Zn, Cd. Extractability consequently concentrations may reduced in some cases by more than 50%. The assessment remediation processes is supported biomonitoring methods field with Plantago lanceolata greenhouse barley test experiments, combination extract...
Genetic differentiation among plant populations and adaptation to local environmental conditions are well documented. However, few studies have examined the potential contribution of plant antagonists, such as insect herbivores and pathogens, to the pattern of local adaptation. Here, a reciprocal transplant experiment was set up at three sites across Europe using two common plant species, Holcu...
Codonopsis lanceolata (Campanulaceae) traditionally have been used as a tonic and to treat patients with lung abscesses. Recently, it was proposed that the extract and some compounds isolated from C. lanceolata reversed scopolamine-induced memory and learning deficits. The purpose of this study was to evaluate the improvement of cognitive enhancing effect of C. lanceolata by steam and fermentat...
