Background: Many species have already been examined regarding their biological activities but there are nevertheless many more which merits examination, among them Carduncellus pinnatus (Desf), that is one of the less abundant and the less frequent aromatic plants of Asteraceae species, it is one species widely distributed in the Mediterranean region. In the present investigation, chemical composition of essential oils of Carduncellus pinnatus and their antioxidant, antimicrobial and antifungal activities were investigated for the first time. Methods: The chemical composition of the essential oils of Carduncellus pinnatus was analyzed by gas chromatography (GC) and gas chromatography mass spectroscopy (GC/MS) during its vegetative cycle. The antioxidant properties were evaluated by DPPH-radical scavenging and FRAP methods. The essential oil was tested on two-gram positive bacteria, three-gram negative bacteria, two filamentous fungi and one yeast. The toxicity of this essential oil was evaluated from several experiments on five mice tested in the laboratory. Results: The chemical composition of essential oils studied by GC and GC-MS showed a total of Twenty-seven compounds constituted mainly by Aplotaxene. Harvest time affected quantitatively but not qualitatively the chemical composition of essential oils. The results showed that Carduncellus pinnatus presented interesting antioxidant property. In order to assess the biological activities of Carduncellus pinnatus, all essential oil samples were combined together to produce a collective essential oil (Coll EO). The Coll EO showed activity on all tested bacterial strains based on the inhibition diameters obtained. The most interesting antimicrobial activity has been observed against Salmonella typhi, Escherichia coli and Staphylococcus aureus with IC50s 0.4, 1.2 and 1.2 g/L, but which remains weak compared to the Gentamicin control, respectively). Regarding antifungal activity, largest inhibition was observed against Fusarium solani (IC50= 0.8 g/L). On the other hand, the toxicity test of Coll EO showed no mortality rate to the concentration of 1g/kg injected to the mice. Conclusion: The results presented here constitutes new findings in the field of the chemical characterization and biological potential of Carduncellus pinnatus.

Background: Atractylis gummifera is a cosmopolitan species that is particularly abundant in the Mediterranean regions. It has been used to treat many diseases, including intestinal parasites, ulcers, snakebite poisoning, hydrops and drowsiness. As part of our research program on natural compounds with biological activities, the objective of this study was to determine for the first time the chemical composition and biological activities of essential oils of Atractylis gummifera during beginning of the vegetative cycle (March), beginning of the flowering stage (April) and full bloom (May/June). Methods: The essential oils were obtained by means of hydrodistillation and its components were analyzed using gas chromatography and mass spectrometry (GC/MS). The antioxidant properties were evaluated using two different methods i) Radical scavenging activity (DPPH) and ii) β-carotene bleaching assay. Whereas, the antifungal activity of the essential oils was investigated against five plant fungi. The fumigation toxicity of essential oils was evaluated against adults of Bactrocera oleae better known as the olive fly. Results: The essential oil produced from the plant taken at the beginning of the vegetative cycle (March) had a high level of non-terpenic aliphatic compounds. On the other hand, the essential oil obtained during the period from the beginning of the flowering stage (April) showed that its proportion of non-terpene compounds decreased and that of sesquiterpene compounds increased. Finally, the essential oils obtained during the period from full bloom (May/June) consisted mainly of acetylene compounds such as carlina oxide and 13-methoxy carlina oxide. The results showed that essential oils from plants at full bloom presented interesting antioxidant and antifungal properties, while essential oil produced from plants at the beginning of the vegetative cycle (Mars) and at the beginning of the flowering stage (April) had better insecticidal activity. Conclusion: The data presented here constitutes new findings in the field of the chemical characterization and biological potential of A. gummifera.

The chemical composition and biological activities of the essential oils from the leaves, stems, and roots of Kadsura coccinea (K. coccinea) were investigated. The essential oils were extracted by hydro distillation and analyzed by gas chromatography mass spectrometry (GC-MS) and gas chromatography with flame ionization detector (GC-FID). Antioxidant activities of the essential oils were examined with DPPH radical scavenging assay, ABTS cation radical scavenging assay, and ferric reducing antioxidant power assay. Antimicrobial activities were evaluated by determining minimum inhibitory concentrations (MIC) and minimum microbiocidal concentrations (MMC). Acetylcholinesterase and butyrylcholinesterase inhibitory activity of the essential oils were also tested. A total of 46, 44, and 47 components were identified in the leaf, stem, and root oils, representing 95.66%, 97.35%, and 92.72% of total composition, respectively. The major compounds of three essential oils were α-pinene (16.60–42.02%), β-pinene (10.03–18.82%), camphene (1.56–10.95%), borneol (0.50–7.71%), δ-cadinene (1.52–7.06%), and β-elemene (1.86–4.45%). The essential oils were found to have weak antioxidant activities and cholinesterase inhibition activities. The essential oils showed more inhibitory effects against Staphylococcus aureus (S. aureus) than those of other strains. The highest antimicrobial activity was observed in the root oil against S. aureus, with MIC of 0.78 mg/mL. Therefore, K. coccinea essential oils might be considered as a natural antibacterial agent against S. aureus with potential application in food and pharmaceutical industries.

Medicinal plants have been used since time immemorial to fight against diseases. The biological activities of these plants may be due to the presence of bioactive compounds such as essential oils. The aim of this study was to determine the chemical composition of three Yemen medicinal plants, and e evaluate their antibacterial and antioxidant activities. The chemical composition of essential oils was determined using gas chromatography–mass spectrometry (GC–MS) analysis. The antibacterial effect was evaluated against pathogenic bacterial strains using the micro-platoon method and the antioxidant activity was estimated by DPPH (2,2-diphenyl-1-picrylhydrazyl) scanning radical assay. Essential oils (EOs) are rich in phenolic compound. Carvotanacetone is the main compound of Pulicaria jaubertii (PJ) essential oil (82.35%) and β-maaliene (64.94%) is the major compound of Plectranthus montanus Benth (PMB) essential oil, while, Tarchonanthus camphoratus (TC) essential oil possesses several main compounds such as fenchol (14.5%), α-pinene (12.43%), and α-terpineol (8.58%). Essential oils of PJ and PMB showed remarkable antibacterial effect against Staphylococcus aureus (minimum inhibitory concentration, MIC = 0.25% [v/v]), and PJEO against Escherichia coli (MIC = 0.25%[v/v]); the lowestMBC (minimum bactericidal concentration) values was obtained with PJEO against Staphylococcus aureus (CMI = 0.25% [v/v]). TCEO interestingly showed capacity while scanning the DPPH radical (6.32 mg E Trolox). These findings showed the biological potential of Yemeni aromatic medicinal plants as antibacterial and antioxidant agents. However, further investigations are needed to determine the antibacterial and antioxidant mechanisms of these oils.

The investigation aimed to study the in vitro and in silico antioxidant properties of Melissa officinalis subsp. officinalis essential oil (MOEO). The chemical composition of MOEO was determined using GC–MS analysis. Among 36 compounds identified in MOEO, the main were beta-cubebene (27.66%), beta-caryophyllene (27.41%), alpha-cadinene (4.72%), caryophyllene oxide (4.09%), and alpha-cadinol (4.07%), respectively. In vitro antioxidant properties of MOEO have been studied in 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) free-radical scavenging, and inhibition of β-carotene bleaching assays. The half-maximal inhibitory concentration (IC50) for the radical scavenging abilities of ABTS and DPPH were 1.225 ± 0.011 μg/mL and 14.015 ± 0.027 μg/mL, respectively, demonstrating good antioxidant activity. Moreover, MOEO exhibited a strong inhibitory effect (94.031 ± 0.082%) in the β-carotene bleaching assay by neutralizing hydroperoxides, responsible for the oxidation of highly unsaturated β-carotene. Furthermore, molecular docking showed that the MOEO components could exert an in vitro antioxidant activity through xanthine oxidoreductase inhibition. The most active structures are minor MOEO components (approximately 6%), among which the highest affinity for the target protein belongs to carvacrol.

The aim of this study was to determine the chemical variability of wormwood extracts as affected by the growing region. Antioxidant and antimicrobial activities were also investigated. The essential oil composition variability ofA. absinthiumL. aerial parts collected from four different Tunisian regions was assessed by gas chromatography (GC/FID) and by gas chromatography mass spectrometry (GC/MS). In addition, total polyphenols, flavonoids, and condensed tannins as well as antioxidant, antibacterial, and antifungal activities of methanolic extract and essential oils were undertaken. Chromatographic analysis of wormwood essential oils showed the predominance of monoterpene hydrocarbons represented mainly by chamazulene. RP-HPLC analysis of wormwood methanolic extract revealed the predominance of phenolic acids. Antiradical activity was region-dependant and the methanolic extract of Bou Salem region has the strongest activity (CI50=9.38±0.82 µg/mL). Concerning the reducing power, the methanolic extract of Bou Salem, Jérissa, and Boukornine regions was more active than the positive control. Obtained results of antimicrobial activities showed that wormwood essential oil is endowed with important antibacterial activity which was strongly related to the organoleptic quality of oil which appeared strongly region-dependant.A. absinthiumL. EOs investigated are quite interesting from a pharmaceutical standpoint because of their biological activities.
