Infusions of Chenopodium ambrosioides (L.) have been used for centuries in the Americas as a popular remedy against intestinal worm infections. The essential oil of Chenopodium ambrosioides contains high levels of ascaridole, which is a potent anthelmintic, but which has also been responsible for human fatalities, leading to its disuse. Almost 90% of the nematocidal activity of Chenopodium ambr...

Background: β-Hematin (Hemozoin) was synthised inside human erythrocyte by malaria parasite. The parasite avoids the toxic effects by polymerizing heme molecules into insoluble crystalline β-Hematin. C. botrys and A. annua used for the treatment of diseases like malaria, hepatitis, cancers, and inflammations. Objective: Determine of antimalarial and anti-protozoa effects of A. anuuae and C. bo...

A research project dealing with the phytoremediation of a soil polluted by some heavy metals is currently running. The case study is represented by a mining area in Hamedan province in the central west part of Iran. The potential of phytoextraction and phytostabilization of plants was evaluated considering the concentration of heavy metals in the plant tissues and also the bioconcentration fact...

In this study, the pollen morphology of allergic Dysphania botrys (L.) Mosyakin & Clemants (Amaranthaceae) taxon, which has a natural distribution within borders Eskişehir province, was investigated in terms and properties. Pollen grains D. are periporatae sphaeroidal shaped. As result microscopic examinations, A/B=1.06 μm (W), A (polar axis): 4.08 µm; B (Equatorial measured at 25.04 μm. Th...

Six natural polyphenolic compounds, brevifolin carboxylic acid, brevifolin, ellagic acid, methyl gallate, gallic acid and protocatechuic acid have been isolated from the methanol extract of the whole plant of Erodium cicutarium (L.) L.'Hérit. (Geraniaceae). Structures were determined by conventional methods of analysis and confirmed by MS and NMR spectral analysis. The distribution of these com...

negatively affected by disturbance. meadow barley (Hordeum brachyantherum Nevski) (Hickman 1993). Purple needlegrass, blue wildrye, bluegrass and California melic are droughttolerant species that typically occupy well-drained upland sites. In contrast, creeping wildrye and meadow barley are less drought-tolerant and typically grow in the moist soils of seeps, streams and wetland margins (Walker...

Four different type 1 ribosome-inactivating proteins (RIPs) with RNA N-glycosidase activity were tested for their ability to attack the large rRNA of plant ribosomes derived from tobacco plants, as well as from the plant species from which the particular RIP had been isolated. Incubation of tobacco ribosomes with RIPs isolated from either Phytolacca americana L. (pokeweed), Dianthus barbatus L....

Ascaridol is the active principle of the American wormseed Chenopodium anthelminticum L. We isolated ascaridol from a commercial preparation of Chenopodium oil and analyzed its activity against different tumor cell lines in vitro (CCRF-CEM, HL60, MDA-MB-231). Multidrug-resistant (MDR) counterparts of these cell lines express differentially the MDR-conferring ATP-binding cassette transporter gen...
