Chemical Compositions of the Essential Oils and Volatile Compounds from the Aerial Parts ofFerula ovinaUsing Hydrodistillation, MAHD, SFME and HS-SPME Methods

Abstract

The present study describes the potential capabilities of four different extraction techniques, namely hydrodistillation (HD), solvent-free microwave extraction (SFME), microwave assisted hydrodistillation (MWHD) and headspace solid-phase microextraction (HS-SPME) to isolate the essential oils and volatile fractions from the aerial parts of Ferula ovina in combination with analysis by GC and GC-MS. By means of the HD, SFME, MWHD and HS-SPME methods, 14, 30, 20 and 28 components were identified in the chemical profiles, representing 100 %, 95.6 %, 97.4 and 98.2 % of the total compositions, respectively. It was observed that in all of the profiles, monoterpene hydrocarbons constituted the main components while the next most common are oxygenated monoterpenes. In addition, the class order of natural compounds through the HD, SFME and MAHD approaches are the same whereas a slightly difference pattern is observed when using HS-SPME.

Profiling of Compositions of Essential Oils and Volatiles of Salvia limbata Using Traditional and Advanced Techniques and Evaluation for Biological Activities of Their Extracts

“…A comprehensive detail concerning the application of the MAHD technique has been given in our previous articles . Briefly, a microwave oven ( Samsung , South Korea) regulated at a frequency of 2450 MHz having a proper internal capacity to house the glass Clevenger set up was employed.…”

“…The main principles of the solvent‐free microwave extraction (SFME) approach have been extensively discussed in our previous reports which are very similar to that of the MAHD method . The main difference between this approach and the MAHD relates to soaking 60‐g portions of the dried and ground organs of the plant material ( Sal .…”

“…For further reliability, we utilized some of the spectral patterns as well as Kovatz indices based on previous findings of our research group 15,[18][19][20][21][22][23][24][25][26][27][28][29] .…”

Chemical composition of the essential oils and extracts of Achillea species and their biological activities: A review

“…Essential oils (EOs) as secondary metabolites involve complex mixtures of natural compounds with versatile organic structures representing useful medicinal properties (Mohammadhosseini and Nekoei, 2014). They can be extracted from different parts of the plant materials using classical and advanced techniques (Mohammadhosseini, 2017).…”

“…Many of these techniques are based on application of microwave under different conditions (Hashemi-Moghaddam et al, 2014;Mohammadhosseini et al, 2015;Mohammadhosseini et al, 2016b). These advanced techniques are secure, fast, environmentally friendly, efficient and also can be conveniently automated (Mohammadhosseini and Nekoei, 2014;Hashemi-Moghaddam et al, 2015). On the other hand, plant extracts are separated from raw and dried samples using aqueous and organic solvents.…”
