phenolic content of daylight-exposed and shaded floating leaves of water lilies (nymphaeaceae) in relation to infection by fungi.	under suboptimal growing conditions (e.g. a lack of sunshine), floating leaves of nymphaea alba and nuphar lutea can become heavily infected with the fungi colletotrichum nymphaeae and pythium f, respectively. these fungi normally act as decomposers of senescent leaves. mature leaves of nymphaea alba and nuphar lutea contain high concentrations of phenolics, secondary substances known for their fungistatic properties. the production of these compounds requires energy and primary metabolites. the ...	1997	28307624
biomonitoring of tin and arsenic in different compartments of a limnic ecosystem with emphasis on corbicula fluminea and dikerogammarus villosus.	asian clam corbicula fluminea, the amphipod dikerogammarus villosus and the macrophyte nuphar lutea were tested for investigating spatial and temporal variability in the bioavailability of tin and arsenic in the river lippe, germany. samples were collected from september 2002 to may 2003 at a tin polluted site (source pollution) and a reference site. additional screening sampling was carried out twice in april 2003 to test the extent of as and sn concentration in periphyton (aufwuchs) samples. a ...	2005	15735779
nuphar lutea: in vitro anti-leishmanial activity against leishmania major promastigotes and amastigotes.	several anti-leishmanial drugs of choice are of plant origin. many of the available drugs against the disease are toxic and in certain cases parasite drug resistance is developed. the development of new compounds is urgently required.	2009	19303752
life form dependent impacts of macrophyte vegetation on the ratio of resuspended nutrients.	the effects of floating-leaved and submerged macrophytes on sediment resuspension and on the ratio of resuspended nitrogen and phosphorus were studied by sediment traps in the kirkkojärvi basin in southern finland. the effect of submerged macrophytes on preventing sediment resuspension was stronger than the effect of floating-leaved plants. on average, among submerged plants the resuspension rate of suspended solids was 43%, and among floating-leaved plants 87% of that in the open water. the flo ...	2009	19505709
antileishmanial activity in israeli plants.	leishmaniasis is a vector-borne disease caused by flagellated protozoan parasites of the genus leishmania, which affects both humans and other mammals. most of the available drugs against the disease are toxic and parasite resistance to some of the drugs has already developed. in the present study, the leishmanicidal activities of methanolic extracts of some israeli plants have been evaluated in vitro, against the free-living promastigotes and intracellular amastigotes of leishmania major. of th ...	2009	19508747
leishmania major: anti-leishmanial activity of nuphar lutea extract mediated by the activation of transcription factor nf-κb.	here we report the effect of a partially purified alkaloid fraction (nup) of nuphar lutea on nuclear factor kappa b (nf-κb) expression and studied its mechanism of toxicity against leishmania major in c3h mice peritoneal macrophages. nup was found to be a mixture of thermo-stable dimeric sesquiterpene thioalkaloids containing mainly thionupharidines. the anti-leishmanial activity was shown to be mediated through the activation of nf-κb and increased inos production. additionally, the nitric oxid ...	2010	20515684
in vitro antibacterial and antitumor activities of some medicinal plant extracts, growing in turkey.	to investigate antibacterial and antitumor activities of 51 different extracts prepared with 3 types of solvents (water, ethanol and methanol) of 16 different plant species (ajuga reptans (a. reptans) l., phlomis pungens (p. pungens) willd., marrubium astracanicum (m. astracanicum) jacq., nepeta nuda (n. nuda) l., stachys annua (s. annua) l., genista lydia (g. lydia) boiss., nuphar lutea (n. lutea) l., nymphaea alba (n. alba) l., vinca minor (v. minor) l., stellaria media (s. media) l., capsella ...	2013	23790332
assessment of the potential biological activity of low molecular weight metabolites of freshwater macrophytes with qsar.	the paper focuses on the assessment of the spectrum of biological activities (antineoplastic, anti-inflammatory, antifungal, and antibacterial) with pass (prediction of activity spectra for substances) for the major components of three macrophytes widespread in the holarctic species of freshwater, emergent macrophyte with floating leaves, nuphar lutea (l.) sm., and two species of submergent macrophyte groups, ceratophyllum demersum l. and potamogeton obtusifolius (mert. et koch), for the discove ...	2016	27200207
fischer's plants in folk beliefs and customs: a previously unknown contribution to the ethnobotany of the polish-lithuanian-belarusian borderland.	historical ethnobotanical studies are useful starting points for further diachronic analysis. the aim of this contribution is to present archival data from the polish-lithuanian-belarusian borderland, which were collected by adam fischer, a polish ethnographer from lviv, in the 1930s. these data were originally gathered for publication in the first part of the lexicon of slavic beliefs and customs, dedicated to plant uses in traditional slavonic culture. it was intended to be a joint internation ...	2017	28335791
