Don. is an important perennial medicinal plant which is belonging to the Apiaceae family. <b>Objective: </b>We aimed to compere Essential Oils (EOs) and antioxidant activity along with other phytochemical properties of<i> Dorema ammoniacum</i> of different populations. <b>Methods:</b> Leaves and stems of 10 populations of</span></span><span lang="EN-GB" style="font-size:10.0pt"><span new="" roman="" style="font-family:" times=""><i>D. ammoniacum</i> were collected from Jiroft, Shahrood, Garmsar, Kerend, Birjand, Kashmar, Bardaskan, Bafq, Mehriz and Neyriz. The essential oil contents were investigated with gas chromatography techniques and compared with the commercial gum-resin essential oil. <b>Results:</b> The EO yield of <i>D. ammoniacum</i> were 0.2-0.3 (stem and leaf) and 1.0 (gum) v/w %, respectively. Essential oils from different organs showed some variation that was correlated to the plant part but also similarities in the EO profiles were easily observed. The major compounds in the EO of gum were (2E,6E)-farnesol, cuparene, (2Z,6Z)-farnesol and <i>&beta;</i>-bisabolene. Endo-Fenchyl acetate, p-cymen-8-ol, cuparene, and <i>&beta;</i>-bisabolene were identified in stem and leaf oil. Analysis of variance of phytochemical characteristics showed that there was a significant difference among all extracts of <span lang="EN-GB" style="font-size:10.0pt"><span new="" roman="" style="font-family:" times=""><i>D. ammoniacum</i> in terms of the Antioxidant Activity (AA), Total Tannin Content (TTC), saponin, Total Phenol Content (TPC) and Total Flavonoid Content (P &le; 0.01). <b>Conclusion:</b> Gum essential oil composition resembles more to leaf-derived <i>D. ammoniacum oil</i>. This study provides new insights into the antioxidant capacity and other phytochemical properties of <i>D. ammoniacum</i>.</span></span></span></span></div> Volatile compounds, Vasha, GC-MS, Antioxidant activity, β-bisabolene 42 63 http://jmp.ir/browse.php?a_code=A-10-916-1&slc_lang=en&sid=1 Mohamad Norani محمد نورانی mohamadnorani1368@gmail.com 100319475328460048064 100319475328460048064 No Department of Horticultural Science, Tarbiat Modares University, Tehran, Iran گروه علوم باغبانی، دانشکده کشاورزی، دانشگاه تربیت مدرس تهران، ایران Mohammad-Taghi Ebadi محمدتقی عبادی mt.ebadi@modares.ac.ir 100319475328460048065 100319475328460048065 No Department of Horticultural Science, Tarbiat Modares University, Tehran, Iran گروه علوم باغبانی، دانشکده کشاورزی، دانشگاه تربیت مدرس تهران، ایران Mahdi Ayyari مهدی عیاری m.ayyari@modares.ac.ir 100319475328460048066 100319475328460048066 Yes Department of Horticultural Science, Tarbiat Modares University, Tehran, Iran گروه علوم باغبانی، دانشکده کشاورزی، دانشگاه تربیت مدرس تهران، ایران
