Barney, J. N. and DiTommaso, A. 2003. The biology of Canadian weeds. 118. Artemisia vulgaris L. Can. J. Plant Sci. 83: 205–215. Artemisia vulgaris L. (mugwort) is an introduced rhizomatous perennial found primarily along roadsides, in waste areas, and in non-containerized nursery crops in eastern regions of Canada and the United States. Artemisia vulgaris is rapidly spreading throughout the Nor...

OBJECTIVES Artemisia is a genus of herbs and small shrubs forms an important part of natural vegetation in Iran. It has been reported that several Artemisia species possess anti-proliferative effects. Considering the value of this genus in anti-cancer researches we have chosen Artemisia biennis for cytotoxic and mechanistic studies. MATERIALS AND METHODS In this study we have investigated the...

BACKGROUND It is necessary to develop novel, affordable, and accessible drugs with few side effects as alternatives of the currently available chemical agents for leishmaniasis. OBJECTIVES The main purpose of this study was to evaluate the effects of these drugs on L. major under in vitro conditions. MATERIALS AND METHODS In the current study, 5, 10, 25, 50, and 100 µg/mL concentrations of ...

Artemisinin (quinghaosu) is a natural compound, isolated from Artemisia annua L. (Compositae), of current interest in treatment of drug-resistant malaria. Aim of the current study was to hit upon novel artemisinin sources as alternative to A. annua. Therefore, ten species of the genus Artemisia (A. santonicum L., A. taurica Willd., A. spicigera K. Koch, A. herba-alba Asso, A. haussknechtii Bois...

BACKGROUND A large number of essential oils is reported to have significant activity against Candida albicans. But the different chemical composition influences the degree of their activity. The intention of this study was to investigate the chemical composition and the activity against Candida albicans of volatile oils obtained from Artemisia dracunculus, A. abrotanum, A. absinthium and A. vul...

PREMISE OF THE STUDY Seed longevity and persistence in soil seed banks may be especially important for population persistence in ecosystems where opportunities for seedling establishment and disturbance are unpredictable. The fire regime, an important driver of population dynamics in sagebrush steppe ecosystems, has been altered by exotic annual grass invasion. Soil seed banks may play an activ...

The aim of the study was to characterise Artemisia pollen season types according to weather conditions in Wrocław (south-western Poland) in the years 2002-2011. Over the period analysed, the start date of the pollen season (determined by the 95 % method) ranged from 10 July 2002 to 28 July 2010. The start date of the pollen season can be determined by using Crop Heat Units (CHUs). During the pe...

Seedling is an indispensable stage in plant cycle life, and seedling survival is important during natural vegetation restoration, especially on the Loess Plateau. In 2007, we selected 4 plots of Artemisia scoparia communities (ASC) and 4 plots of Artemisia gmelinii + Artemisia giraldii communities (AGC), examined seedling richness, diversity during the rainy season, and examined mature vegetati...

OBJECTIVE To evaluate the aqueous extract from aerial parts of Artemisia copa Phil. (Asteraceae) administered orallyfor its psychopharmacological activities in several experimental models. METHODS The extract was administered p.o. in Swiss albino mice and tested on pentobarbital-induced hypnosis, locomotor activity, exploration in the hole-board, anxiolytic like profile evaluated in the marbl...

Two very common groups of oxylipins formed in plants involve the conversion of fatty acid hydroperoxides, such as hydroperoxy-octadecatrienoic acid, into further metabolites by allene oxide synthase and hydroperoxide lyase. Both of these oxylipin branch pathways appear to be ubiquitous or nearly so in plants, but the relative activities of these two branches vary among plant species. In most pl...
