Two species of the Rosaceae genus Geum, comprising high amounts of tannins and phenolic acids, were investigated in terms of their antioxidant activity. Antioxidant potential of different extracts from aerial and underground parts of Geum rivale and G. urbanum was studied using various in vitro methods (FC, DPPH, FRAP and linoleic acid peroxidation test). The hydromethanolic extract from the ro...

This is a molecular phylogenetic study of the group formerly known as Dryadeae, based on DNA sequences from the internal transcribed spacers, ITS, of nuclear ribosomal DNA and the trnL intron and the trnL-trnF intergenic spacer of the chloroplast. A total of 1.9 kb, for 26 ingroup species, were analyzed using parsimony and model-based Bayesian inference. Some clades are well supported by both d...

An extract of an unidentified green filamentous fungus isolated as an endophyte of the Canadian medicinal plant Geum macrophyllum exhibited significant antimycobacterial activity and a distinct 1H NMR profile. Bioassay guided fractionation indicated that the natural product phomopsolide A (1) was responsible for the distinguishing characteristics of the extract.

Five gradient concentrations (0.02, 0.04, 0.06, 0.08, and 0.10 g/mL) of leaching liquors from the roots, stems, and leaves of the invasive plant Bidens frondosa were used as conditioning fluid to examine its influence on seed germination conditions of the native plant Geum japonicum var. chinense in Huangshan. All leaching liquors of organs suppressed the seed germination of Geum japonicum var....

New host plant records are given for six Empria species from Japan. They are Rosa multiflora [Rosaceae] for E. honshuana Prous & Heidemaa, 2011, Rubus sp. [Rosaceae] for E. japonica Heidemaa & Prous, 2011, Geum japonicum and G. calthifolium var. nipponicum [Rosaceae] for E. loktini Ermolenko, 1971, Rosa multiflora, Potentilla indica and probably Rubus parvifolius [Rosaceae] for E. quadrimaculat...

The impacts of two factors on future regional-scale runoff were assessed: the external factor of climate change and the internal factor of a recently completed large-scale water resources project. A rainfall-runoff model was built (using the Soil and Water Assessment Tool, SWAT) for the Geum River, where three weirs were recently constructed along the main stream. RCP (Representative Concentrat...
