the study was carried out to investigate the effective soil and topographic features on distribution of plant types in sanib taftan watershed in sistan-and-balouchestan province, iran. initially, land units map was specified by combining three maps of slope, aspect and altitude. five types including artemisia santolina- hammada salicornica, artemisia sieberi- amygdalus lycioides, artemisia lehm...

The Achillea L. genus has a wide distributional range, and the differences in oil composition may be affected by different environmental factors such as soil mineral fertilization, the climate conditions and the culture site. To evaluate the effect of temperate climate on content and chemical combination of essential oil of Achillea filipendulina Lam,  A. arabica Kotschy and A. eriophora DC., t...

Background & Aim: The genus Tanacetum L. belongs to the family Asteraceae and tribe Anthemideae. According to the recent findings the number of Tanacetum species in Iran is 36, of which 12 are endemic. In this study the essential oil composition of Tanacetum chiliophyllum var. oligocephalum was investigated for the first time.   Experimental: The plant was c...

objective during the last three decades sesquiterpenoid lactones have emerged as one of the largest groups of plant products with over 3000 naturally occurring substances known. the genus artemisia characteristically contains this biologically active type of secondary metabolites. with respect to increasing interest in the cytotoxic, antibiotic, phototoxic and antineoplastic activities of sesqu...
