Short Paper: Anti oxidant evaluation and phenolic contents in different extracts of Ferula assa-foetida resin in South Khorasan province

The present study conducted to evaluation of anti oxidant and phenolic content of aqueous and hydro alcoholic extracts of Ferula assa –foetida L. Plant was collected from Birjand located in south Khorasan province (1470m). Aqueous and hydro alcoholic extracts of plant were obtained by maceration method, total phenolic content was measured by folin sicalto in spectrophotometery and anti oxidant activity by scavenging free radicals of DPPH in spectrophotometry. Results showed that the hydro alcoholic extract with high phenolic content (228 mg GAE/g) and with IC50=0.415mg/ml have more anti oxidant activity than aqueous extract to free radical scavenging.
