本研究では、イラン産の属植物のファイトケミカルプロファイル、精油組成、抗酸化作用、抗真菌作用について検討した。GC-MS分析により精油収量は1.5%(w/v)であり、主要な化合物は樟脳(33.64%)、1,8-シネオール(25.66%)、クリサンテノン(7.86%)であり、22成分が同定された。抽出物の総ポリフェノール及びフラボノイド量、総アスコルビン酸量、カロテノイド量を測定した結果、それぞれGAE/100g DW 666.26mg、QUE/100g DW 54.77mg、153.585mg/100g DW、907.18mg/100g FWという結果が得られた。DPPHバイオアッセイに基づく抗酸化活性は、精油（84.04％）と抽出物（89.33％）が最も高い値を示した。さらに、抗真菌活性を試験した精油は、1000および1500μllの濃度で菌糸体の増殖率を有意に低下させることが示された。

In this study, the phytochemical profile, the essential oil composition of an Iranian accession of and their antioxidant and antifungal properties were investigated. The amount of essential oil yield was 1.5% (w/v) and twenty two components were identified by GC-MS analysis being camphor (33.64%), 1,8-cineole (25.66%) and chrysanthenone (7.86%) the major compounds. The amount of total polyphenols and flavonoids, total ascorbic acid and carotenoid content of extract were determined, and resulted in 666.26 mg GAE/100g DW, 54.77 mg QUE/100g DW, 153.585 mg/100g DW, and 907.18 mg/100g FW, respectively. Highest antioxidant activity based on DPPH bioassay was recorded in essential oil (84.04%) and extract (89.33%). Furthermore, the essential oil of tested for its antifungal activity, demonstrated to reduce significantly the mycelium growth rate of , that is, no mycelial growth was observed at concentrations 1000 and 1500 μll.
