This study provides data on the problem of potential complexation phenolic compounds synthesized by plants Solidago canadensis L. and gigantea Ait. with ammonium forms nitrogen, partly immobilized in soil. A comparative analysis secondary metabolites studied was performed HPLC. The leaves invasively active contain nine times more rutin than gigantea. Adding to leaf extracts (v/v1/20) aqueous ammonia solution pH 8.0 chromatograms decreases intensity or completely causes peaks flavonoids...

Стаття присвячена вивченню рудеральних угруповань, сформованих Calamagrostis epigejos та Rubus caesius, приурочених до ділянок з відносно бідними легкими ґрунтами, що утворюють бордюри між лісовими, трав’яними ценозами комунікаційними шляхами. Трав’яний покрив досліджених угруповань досить строкатий, сформований рудеральними, лучними узлісними видами. Було виділено дві асоціації Rubo сaesii-Calamagrostietum еpigeji Elymo repentis-Rubetum caesii, які відносяться союзу Convolvulo...
