Phytochemical and Antioxidant Activity of the Essential Oils of Satureja briquetii L. from Morocco

Abstract

Satureja briquetii L. (Labiatae) species are a well-known aromatic plant which is used to produce essential oils and aromatic water in the mountain regions of Sefrou part of Morocco. In our study, it was aimed to determine phytochemical and antioxidant activities of Satureja briquetii L. essential oils in vitro. Antioxidant activities of the oils at differents concentrations were evaluated using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging. The extraction of essential oils from aerial part of this plant is carried out by hydrodistillation, and yields are 1.75% for dry aerial part and 1.05% for fresh aerial part. The analysis of the essential oils of dry aerial part from Satureja briquetii L. by GC/MS identified 57 principles compounds including Spathulenol (9.81%), Verbenone (4.35%), Camphene (3.56%), Himachalene (3,2%) and Cedrene (2,12%). The chromatographic profile of essential oils from fresh aerial part of Satureja briquetii L. has 49 constituents representing 96.25% of the essential oil, where the Menth-8-ene (14.99%), Cymene (4.97%) and Carene (4.97%) are major compounds. The Menth-1,4(8)-diene, (1,06%), Cubenol and Longifolene (3,44%) are in minority. Furthermore, the antioxidant activity of the essential art of Satureja briquetii L. was evaluated by the method of DPPH, and showed a significant efficiency in radical DPPH reducing with an IC50 value of of 31.027 ± 0.586 µg/ml from essential oils of dry aerial and 35.034 ± 0.0432 µg/ml in essential oils from fresh aerial part.

Effectiveness of essential oil from the Artemisia herba-alba aerial parts against multidrug-resistant bacteria isolated from food and hospitalized patients

“…Component identification was based on a comparison of mass spectra with mass spectra libraries (NIST MS SEARCH 2.0) and a comparison of the retention index (RI) of the components measured relative to n-alkanes on nonpolar columns with those present in literature data (Salido et al 2004;Mohsen and Ali 2009;Paolini et al 2010;Ouaritini et al 2016;El-sharkawy et al 2018;Amor et al 2019). The percentage of composition of EOs was determined from the FID response without applying correction factors.…”

Chemical Differentiation and Antimicrobial Potential of Four Brassica napus L Seed Oils

“…The process was left to run for 3 hours. The essential oils were collected in tightened vials and stored at 10 °C [2].…”

“…Gas chromatography-mass spectrometer (GC-MS) analysis was used for the phytochemical investigations of the essential oils contained in 4 varieties of rapeseeds, following the procedure described by Seow et al, Oroojalian et al, and Ahmed et al [2,3,9]. Phytochemical analysis of each oil extract was achieved by using Shimadzu QP-2010 GC gas chromatograph-mass spectrometer.…”

“…Usually, their extraction is achieved by steam distillation or Soxhlet extraction and their phytochemicals are analyzed by gas chromatography-mass spectrometry. Based on the seed varieties and climate, the oil yields range between 30-45% [2]. Brassica napus is well identified as a rich oil plant with minimum saturated fatty acids (5-7%) and maximum polyunsaturated fatty acids which are estimated to contain 7-10% α-linolenic and 17-21% linoleic acids.…”

“…Plant extracts from herbs and plant seeds are mostly known for their phenolic and flavonoid contents that exhibit different antimicrobial activities [2]. For instance, some variances of Brassica napus L oils were shown to suppress the growth of Klebsiella pneumonia, Staphylococcus epidermidis, and Pseudomonas originals [6].…”
