Objectives Tanacetum species are traditionally used as insecticide, and externally wound healer as well as for anti-inflammatory and antihistaminic properties. The in vivo wound-healing and anti-inflammatory potential of four Tanacetum species, Tanacetum argenteum (Lam.) Willd. subsp. argenteum (TA), Tanacetum heterotomum (Bornm.) Grierson (TH), Tanacetum densum (Lab.) Schultz Bip. subsp. sivas...

Abstract Due to their small sizes and high reactivity, nanoparticles have a completely different toxicity profile than larger particles, it is difficult predict potential ecological impact. There need for broad ecotoxicological studies of nanomaterials in order specify environmental impact ensure safe application nanotechnology products. In this work, we assessed the Au Au/ZnO metal obtained wi...

Parthenium dermatitis is an immuno-inflammatory disease caused by Parthenium hysterophorus and is the commonest cause of plant dermatitis in India. It is caused by airborne dry and friable plant particles including trichomes, and the most important allergens responsible for allergic contact dermatitis are sesquiterpene lactones. The combined type IV and type I hypersensitivity to parthenium has...

Field and greenhouse experiments were conducted during 2005 and 2006 at Stoneville, MS, to determine control of ragweed parthenium with several preemergence (PRE) and postemergence (POST) herbicides registered for use in corn, cotton, peanut, rice, and soybean. Norflurazon, pendimethalin, clomazone, diuron, fluometuron, pyrithiobac, dimethenamid, flumetsulam, imazaquin, s-metolachlor, metribuzi...

parthenolide is major sesquiterpene lactones present in anthemis haussknechtii boiss. & reut. (feverfew). this compound has many effects on different disease such as migrain and cancer. parthenolide was reported from tanacetum parthenium (l.) sch.bip. but other plants of asteraceae family could contain parthenolide. in this study parthenolide was extracted and identified with two methods, fouri...

The polyphenolic composition and antioxidant activity of the aerial parts of 18 medicinal or food plants of the Asteraceae family were studied. Five main caffeoyl derivatives were determined individually by HPLC and compared with levels determined by colorimetry for total dihydroxycinnamic derivatives and total phenolics. The aim of this study was to assess the contribution of these constituent...
