Some damage caused in tobacco necrosis virus by u.v. radiation could be repaired in darkness in Chenopodium amaranticolor (dark reactivation) but not in French bean or in tobacco. By contrast, photoreactivation of the irradiated virus was observed in French bean and in tobacco but not in Chenopodium. The kind of damage in u.v.-irradiated virus that is susceptible to repair by photoreactivation ...

AIM Detection of monoterpenoid ascaridole and other terpenoids in the genus Chenopodium from the East Mediterranean. METHOD Distribution of ascaridole in leaves of 13 species medicinal plant belonging to the genus Chenopodium was examined with the help of the GC MS method. RESULTS cis Ascaridole was found as a major peroxy monoterpenoid (up to 46.9 %) in the oil. Three minor isomers: cis is...

A comparative carpological study of 96 species of all clades formerly considered as the tribe Chenopodieae has been conducted for the first time. The results show important differences in the anatomical structure of the pericarp and seed coat between representatives of terminal clades including Chenopodium s.str.+Chenopodiastrum and the recently recognized genera Blitum, Oxybasis and Dysphania....

The leaves and the oil from the seeds of Chenopodium ambrosioides L. (Chenopodiaceae), a plant known in Brazil as 'mastruz', have been used by native people to treat parasitic diseases. Experimentally it was shown that Chenopodium ambrosioides inhibits the Ehrlich tumor growth, what could be due to an immunomodulatory effect of this product. The aim of this study was to investigate the effect o...

Chenopodium (American wormseed) is one of the most widely-used anthelmintics at the present time. It was used by the American Indians in the days of Columbus, and in South America infusions made from leaves and seeds have been used as a household remedy against intestinal parasites for a long time. Baumler and Fribourg introduced the drug into Europe in 1881 for the treatment of hookworm diseas...

Antifungal potential of aqueous extracts of forty plants of different families were tested against Fusarium oxysporum f.sp. ciceri causal agent of wilting of chick pea. Among forty plant species tested aqueous extract of Chenopodium ambrosioides has recorded significant antifungal activity against the test fungi. Solvent extracts viz. petroleum ether, benzene, chloroform, and methanol and ethan...

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...

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...
