[email protected] The present work was identified the chemical compounds of essential oil (EO), evaluated the antioxidative activities, phenolic and total phenolic contents (TPCs) from aerial parts of Ferula assa-foetida and its oleo-gum-resin. The EO components were analyzed by gas chromatography (GC-FID) and gas chromatography/mass spectrometry (GC/MS). Polyphenolic compounds of metanolic extract of its plant and its oleo-gum-resin were examined by using HPLC analysis. The TPC was assessed by Folin-Ciocalteu method. Furthermore, radical scavenging activity of sample was assessed using Diphenylpicrylhydrazyl (DPPH). Essential oil's analyses showed that 10-epi-ɣ-eudesmol( 18.3%), α-eudesmol (10.9%), agarospirol (7.1%), β-eudesmol (6.6%) and guaiol (5.8%) were the main components from F. assa-foetida aerial parts and α-pinene (22.6%), (Z)-1-propenyl sec-butyl disulfide (20.4%), β-pinene (12.1%), (E)-1- propenyl sec-butyl disulfide (6.6%) and bicyclogermacrene (4.1%) were the main components from its oleo-gum-resin. Chloregenic acid (2.6 mg/g), ellagic acid (1.3 mg/g), quercetin (0.18 mg/g) and vanillin (0.05 mg/g) were the main polyphenols detected in extract of plant.
