“…(derbeb) [17], P. undulata [34][35][36][37], and P. vulgaris Gaertn. (false fleabane) [38][39][40], was assessed by agglomerative hierarchical cluster (AHC) as well as principal component analysis (PCA). We constructed a data matrix from the percentage of various classes of the EO (mono-, di-, sesquiterpenes, and others) in different Pulicaria species (12 species representing 21 samples) and then subjected them to PCA.…”

Pulicaria genus (fleabane) is characterized by its fragrant odor due to the presence of essential oil (EO). According to the literature reviews, the EO of Pulicaria somalensis O.Hoffm. (Shie) is still unexplored. For the first time, 71 compounds were characterized in EO derived from above-ground parts of P. somalensis collected from Saudi Arabia. Sesquiterpenes represented the main components (91.8%), along with minor amounts of mono-, diterpenes, and hydrocarbons. Juniper camphor (24.7%), α-sinensal (7.7%), 6-epi-shyobunol (6.6%), α-zingiberene (5.8%), α-bisabolol (5.3%), and T-muurolol (4.7%) were characterized as main constituents. The correlation analysis between different Pulicaria species showed that P. somalensis has a specific chemical pattern of the EO, thereby no correlation was observed with other reported Pulicaria species. The EO showed significant allelopathic activity against the weeds of Dactyloctenium aegyptium (L.) Willd. (crowfoot grass) and Bidens pilosa L. (hairy beggarticks). The IC50 value on the germination of D. aegyptium was double that of B. pilosa. The IC50 values on the root growth of B. pilosa and D. aegyptium were 0.6 mg mL−1 each, while the shoot growths were 1.0 and 0.7 mg mL−1, respectively. This variation in the activity could be attributed to the genetic characteristics of the weeds. Moreover, the EO exhibited significant antioxidant effects compared to ascorbic acid. Further studies are necessary to verify if these biological activities of the EO could be attributable to its major compounds.

“…However, the chemical composition of the essential oil from the aerial parts of P. vulgaris var. graeca grown in Sicily (with a completely different climate from that of Tunisia) was studied by Casiglia et al (2016), who reported the identification of 52 components. One of the main constituents of this oil, hexadecanoic acid (21.7%), was not detected in our Tunisian oil.…”

Essential oils obtained by hydrodistillation from the aerial parts and roots of Pulicaria vulgaris Gaertn. subsp. dentata Batt. cultivated in Tunisia were analyzed by GC-FID and GC-MS. Twenty-one compounds (97.2% of the total oil composition) were characterized in the oil of the roots, with γ-irone (39.2%), 7-epi-silphiperfol-5-ene (19.3%), 2,5-dimethoxy-p-cymene (8.5%) and γ-himachalene (8.0%) as main constituents. On the contrary, the essential oil of the aerial parts was particularly rich in cis-β-guaiene (59.7%), together other eighteen compounds, accounting for 93.2% of the total oil composition. Antiradical (DPPH, ABTS and reducing power) and enzymatic antioxidant properties (Catalase and Paraoxonase) of the isolated oils were also evaluated. The essential oil of the roots exhibited the highest antioxidant activity in the assay with DPPH (IC 50 = 0.037 ± 0.002 mg/mL), ABTS (IC 50 = 0.078 ± 0.001 mg/mL), catalase (477.325 ± 0.315 Units/mg protein) and paraoxonase (40.07 ± 0.23 µM/min/L). Antimicrobial, cytotoxic, cholinesterase and tyrosinase inhibition properties of these essential oils have been also studied. Essential oil of the aerial parts exhibited significant activity towards Pseudomonas syringae (IZ = 20± 1mm) and Agrobacterium tumefasciens (IZ = 19± 0.57mm). The essential oil of roots showed the best cytotoxic effect against Hela cell line (IC 50 = 96.87 ± 0.23 µg/mL), the highest activity against butyrycholinesterase (IC 50 = 0.022 ± 0.013 mg/mL ) and 76% of inhibition against tyrosinase at 100 µg/mL from the incubation time of 30 min.

“…The antimicrobial activity of these hydrophobic compounds has been attributed for their ability to disrupt the bacterial cell membrane by causing excessive cell permeability (Taweechaisupapong et al 2012). Antimicrobial activity of essential oils is one of the most examined features, important for both food preservation and control of microbial human and animal diseases Numerous reports suggest strong antibacterial and antifungal activities of a wide range of essential oils, especially those belonging to the Asteraceae family (Rios 2015, Casiglia et al 2016. However, in order to get more relevant data about the influence of some essential oil compounds on the activity cited, further examinations are necessary.…”

Altuntas et al. 2016) and so they have wide variety of applications areas including raw and processed food preservation, pharmaceuticals, alternative medicine and natural therapies. Natural essential oils are more preferable compared to the synthetic chemicals which are used for protection of food products against deterioration because despite having broad spectrum against both Gramnegative and Gram-positive bacteria they do not create any bacterial resistance and so safe for human health and do not cause environmental pollution as synthetic ones. Moreover essential oils can act as an antioxidant and neutralize
