Ferula genus belongs to Umbelliferae family. Plants with this kind of genus are distributed in an extended region such as central Asia and Mediterranean area. Ferula species are used in traditional medicine as a remedy in different kinds of illnesses and also in different kinds of industries. The Ferula haussknechtii H. Wolff ex Rech. f. is one of the flora species in Iran which in this research the essential oil of its aerial parts and root was extracted by Clevenger apparatus. After that, theirs compounds were recognized using gas chromatography methods (GC‐MS and GC‐FID) and their amount was determined. Antibacterial activity of essential oils was examined, and phytochemical screening on the plant's extracts was done too. GC‐MS/FID method identified 62 compounds in root and 64 compounds in aerial parts of this plant which were 94.6 and 92.8 percent of their respective whole essential oil. Camphene, α‐pinene, and isoverbanol had the most percent in both essential oils. Antibacterial tests on root and aerial parts of plant essential oils on 4 g‐negative and 5 g‐positive bacteria were done. Results concluded that essential oils were effective on the Bacillus pumilus, Staphylococcus epidermidis, and Staphylococcus aureus (17‐18mm, 7.5 mg/mL); therefore, this plant can be useful in medicine and food industry as an antibacterial agent.

Ferula haussknechtii地上部分和根部的精油的化学表征和生物活性

阿魏属植物属于伞形科。具有这种属的植物分布在中亚和地中海地区等扩展地区。在传统医学中，阿魏类物种可作为多种疾病和不同行业中的一种补救方法。费拉斯（Ferula haussknechtii）H. Wolff前Rech。F。伊朗是伊朗的一种植物区系，在该研究中其地上部分和根的精油是用Clevenger仪器提取的。之后，使用气相色谱法（GC-MS和GC-FID）识别其化合物，并确定其含量。检查了香精油的抗菌活性，并对植物提取物进行了植物化学筛选。GC-MS / FID方法鉴定出该植物根部的62种化合物和地上部分的64种化合物，分别占其整个精油的94.6和92.8％。在两种精油中，樟脑，α-pine烯和异丁烷含量最高。对植物精油的根和地上部分对4 g阴性和5 g阳性细菌进行了抗菌测试。结果得出结论，精油可有效治疗短小芽孢杆菌，表皮葡萄球菌和金黄色葡萄球菌（17-18mm，7.5 mg / mL）; 因此，这种植物可以作为抗菌剂在医药和食品工业中使用。
