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.

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.

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.

AbstractThe present study investigates the chemical compositions of three Satureja montana L. ssp montana essential oils and correlates chemical variability with biological activities. GC/MS analysis showed that with an increase in altitude (100–500–800 m), a higher content of linalool, terpinen-4-ol and cis-sabinene hydrate was found, while the percentage of phenolic compounds, thymol and carvacrol decreased. Antimicrobial activity of the essential oils was tested against 7 fungal and 23 bacterial strains. The essential oil characterized by the highest content of phenols and alcohols exhibited the highest antimicrobial potential. The correlation analysis showed that the major carriers of the obtained antioxidant activity are oxygenated monoterpenes. All essential oils inhibited human serum cholinesterase activity. High antimicrobial potential, together with moderate antioxidant capacity and strong inhibition of human serum cholinesterase, classifies S. montana essential oil as a natural source of compounds that can be used in the treatment of foodborne and neurological diseases, wound and other infections, as well as for general health improvement.

Antioxidant And Antimicrobial Activities

Citrus species of plants are among the most commercially cultivated crops, mainly for their fruit. Besides, the generally consumed flesh inside the fruit, the peel is quite important too. Essential oils extracted from the peel have a history of being used by humankind for centuries. These essential oils are rich in antioxidants and antimicrobial agents. Comparative investigation of volatile constituents, and antioxidant and antimicrobial activities were undertaken. The essential oils were evaluated through gas chromatography-mass spectrometry (GC–MS), and enantiomeric composition by chiral GC–MS. Similarly, the antioxidant properties were evaluated by 2,2-diphenyl-1-picrylhydrazyl scavenging assay, and antimicrobial activities were assayed using the disk diffusion method. The highest extraction yield of 1.83% was observed in Citrus sinensis Osbeck. GC–MS analysis showed limonene (63.76–89.15%), γ-terpinene (0.24–6.43%), β-pinene (0.15–6.09%), linalool (0.35–3.5%), sabinene (0.77–2.17%), myrcene (0.74–1.75%), α-terpineol (0.28–1.15%), and α-pinene (0.2–0.58%) as the major constituents of the essential oil of the Citrus species studied. For the first time, through our study, chiral terpenoids have been observed from Citrus grandis Osbeck essential oil. The order of antioxidant activity is as follows: Citrus grandis Osbeck red flesh > Citrus reticulata Blanco > Citrus sinensis Osbeck > Citrus grandis Osbeck white flesh. Except for Citrus grandis Osbeck white flesh (52.34 µL/mL), all samples demonstrated stronger antioxidant activities than those of the positive control, quercetin (5.60 µL/mL). Therefore, these essential oils can be used as a safe natural antioxidant to prevent product oxidation. Likewise, citrus peel essential oil showed antimicrobial activity against tested bacterial strains, albeit marginal.
