Investigating the composition of essential oils in different parts of the Ferula assa-foetida medicinal plant and comparing with plant gum

Ferula assa-foetida is a medicinal plant native to Iran that has traditionally been considered for its therapeutic value traditionally. In this research, the composition of essential oils in different parts of the plant (stem, seed, and leaf) and its gum were compared. For this purpose, It was identified as the pasture habitat of this important species in Taft city )Yazd (and was randomly collected from the existing plant of the investigated sections in three samples at the time of appearance, flowering and seeds. The essential oils of the samples were taken using a Cloninger and the chemical compounds found in the essential oils obtained from different organs were analyzed by gas chromatography (GC/FID) and mass spectrometry (GC-MS). In the investigation of the essential compounds of the gum, leaf, stem, and seed parts of the plant, 25 compounds were identified, which made up 90.24% of the gum, 91.84% of the leaf, 85.09% of the stem, and 95.70% of the seed. Based on the obtained results, it was found that most of the main compounds in the essential oil of gum are similar to compounds in other organs. Volatile sulfur compounds, along with sesquiterpenes were the dominant compounds of the essential oils of these four organs. So the three compounds (E)-propenyl sec-butyl disulfide, (Z)-Propenyl-sec-butyl disulfide and γ-Eudesmol are the most important essential oil compounds, which account for more than 50% of the essential oil composition and there is the most similarity between the composition of gum essential oil and leaf.
