Essential oils obtained from aerial parts of Artemisia persica and Artemisia turcomanica were analyzed by GC/MS. While 28 components representing 91.01 % of A. persica were identified, the identity of 50 components, constituting 81.93 % of the total oil, was confirmed in A. turcomanica. β-thujone was the main compound (75.23%) in A. persica while the major identified phytochemicals in A. turcom...

Seasonal changes in antioxidant enzymes activities, amount of water, ash, proline and soluble sugars were surveyed during this research in four halophyte species of Varamin County, Tehran, Iran: Salsola turcomanica Litwin, Suaeda arcuata Bunge, Tamarix leptopetala Bunge and Cressa cretica L. Plants were collected randomly from their natural habitats in spring and summer. Activity of these enzym...

The aerial parts of Stachys laxa Boiss. and Buhse. from Siah-bishe in Mazandaran province, Stachys trinervis Aitch. and Hemsl. from Karaj in Alborz province, Stachys subaphylla Rech. F. and Stachys turcomanica Trautv. from Golestan province have been collected in May 2008. Total extracts were obtained through MeOH/H2O (80/20) and then partitioned between CHCl3, EtOAc and MeOH. These fractions a...

Halophyte microbiome contributes significantly to plant performance and can provide information regarding complex ecological processes involved in osmoregulation of these plants. The objective of this study is to investigate the microbiomes associated with belowground (rhizosphere), internal (endosphere) and aboveground (phyllosphere) tissues of halophyte (Salsola stocksii) through metagenomics...

Hymenoclea salsola, Asteraceae, Resin Flavonoids, 2',4',6 'OH Chalcone Hymenoclea salsola (Asteraceae), a dominant shrub of the desert areas of California and Baja California, Mexico, secretes high amounts of resin on the leaf surface. Chemi­ cal analysis of the resin revealed the presence of a complex mixture of flavonoid aglycones. Among the compounds identified is the rare 2',4',6'-OH chalco...

Sequence data from four gene regions (nrDNA, petN-psbM, trnD-trnT, trnS-trnG, 3,705 bp) revealed that junipers from the southern mountain ranges of Iran are very diverse. The combined NJ tree (3,705 bp) showed strong support for the distinct nature of J. excelsa, J. polycarpos, J. p. var. turcomanica, and J. p. var. seravschanica. The samples from NW Iran are J. polycarpos and samples from NE I...
