the essential oils of the aerial parts of three different artemisia species (a.scoparia, a. diffusa, a. turanica ) growing wildly in the northeast of iran were analyzed by gc-ms. twenty-two, twenty-six, and thirteen components were identified in the essential oils of these plants, respectively. the major constituents of the oil ofa. scoparia were b-pinene (16.10%), carvacrol (13.81%), limonene ...

The aerial parts of Artemisia chamaemelifolia Vill. afforded, in addition to five known sesquiterpene acids, a new 5-epi-cantabrenolic acid (6).

Ferula haussknechtii H. Wolff ex Rech.F. is an important medicinal plant belonging to the Apiaceae, family. In order to investigate the effect of Pb on the growth, chemical composition of essential oil and accumulation of metals in this species, a pot study was conducted under glasshouse condition. Seeds were collected from natural rangelands of Lorestan province, Iran in summer 2016. ...

Haemonchus contortus is a blood-sucking abomasal parasite of small ruminants that is responsible for major losses to producers worldwide. Resistance of this nematode to commercial anthelmintics has produced a demand for alternative control methods. Plants in the genus Artemisia have traditionally been used as anthelmintics and whole plants and plant extracts have demonstrated activity against g...

Similar to vascular plants, non-vascular plant mosses have different periods of seasonal growth. There has been little research on the spectral variations of moss soil crust (MSC) over different growth periods. Few studies have paid attention to the difference in spectral characteristics between wet MSC that is photosynthesizing and dry MSC in suspended metabolism. The dissimilarity of MSC spec...

The Chinese mugwort (Artemisia argyi Lév. et Vaniot) is an important traditional medicine plant that ubiquitously disturbed in Asia. However, the molecular mechanisms reflect natural evolution of Artemisia remain unclear. In this study, a high-quality draft assembly allotetraploid A. (ArteW1-Tongbai) was conducted utilizing PacBio long-read sequencing and Hi-C technologies. about 7.20 Gb with c...

The present study describes the reproductive ecology of the prostrate shrub Juniperus sabina and the dwarf shrub Artemisia santolinifolia in dry mountain steppes of southern Mongolia. Whereas stands of the juniper are located at the drought limit of the genus’ distributional range, the genus Artemisia is typical of central Asian drylands. Both species produce large numbers of reproductive organ...
