Subject RIV EH - Ecology, Behaviour R&D Projects OC D28.001 GA MŠMT - Ministry of Education, Youth and Sports (MEYS) CEZ AV0Z60870520 - UEK-B (2005-2011) Annotation There tall perennial species of Reynoutria have spread into the European region from Asia. There are also three annual species of Impatiens common and widespread in Europe (I noli-tangere is native to Europe, I. parviflora to Asia, I glandulifera to the Himalayas).The investigated genera have different life history strategies, but are very invasive in their original biotopes in Europe. The dominant phenolic compounds in the methanolic extract of Reynoutria and Impatiens genera were investigated using high performance liquid chrpomatography.Derivates of quercetin were found in the above-ground biomass of all genera, but in addition catechin was found in Reynoutria species and derivates of caffeic acid found in the three Impatiens species.Differend dominant phenolic compounds were found in underground parts of the plants. Rhizomes of Reynoutria species contained mainly stilbenes and catechins, but the Impatiens genus contain naphthoquinones.
