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.

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.

The volatile compounds of the fruit and leaf essential oils of the African star fruit, Chrysophyllum albidum G. Don, were characterized by gas chromatography-mass spectrometry in this study. The antimicrobial, antibiofilm, and antioxidant activities of the essential oils were also investigated. Thirty-five and thirty-four compounds, representing 97.84% and 97.87%, were identified in the leaf and fruit essential oils, respectively. The antimicrobial activity of the oils was evaluated in vitro against eight pathogens using the broth microdilution method. The fruit essential oil exhibited broad-spectrum antimicrobial activity in the antimicrobial susceptibility test, with minimum inhibitory concentrations (MICs) ranging from 0.195 to 6.250 mg/mL, while the leaf essential oils showed antimicrobial activity with MICs in the range of 6.875–13.750 mg/mL. The antibiofilm activity was assessed via the crystal violet staining assay, with Pseudomonas aeruginosa as the model organism. The concentrations of the leaf and fruit essential oil required for half-maximal inhibition of biofilm formation (BIC50) were 6.97 ± 0.56 and 4.78 ± 0.21 mg/mL, respectively. In evaluating antioxidant activity, the total antioxidant capacity obtained from the phosphomolybdenum assay was 104.8 ± 2.4 and 101.6 ± 0.8 μg/g AAE for leaf and fruit essential oils, respectively. The IC50 values obtained from the hydrogen peroxide scavenging, 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging, and inhibition of lipid peroxidation assays were 301.8 ± 0.7 and 669.2 ± 2.1 μg/mL, 1048.0 ± 0.3 and 1454.0 ± 0.3 μg/mL, and 460.1 ± 2.7 and 457.4 ± 0.3 μg/mL for both leaf and fruit essential oils, respectively. The results obtained in this study suggest that the leaf and fruit essential oil of Chrysophyllum albidum G. Don could find potential use in the food, cosmetic, and pharmaceutical industries as preservative and pharmaceutical agents.

AbstractThe chemical composition of the essential oils from the leaves and fruit ofEucalyptus camaldulensisgrown in Mersin, Turkey was analyzed using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) techniques. The biological activities (antibacterial and antifungal) were examined using the agar well diffusion method. The main leaf oil constituents werep-cymene (42.1%), eucalyptol (1,8-cineole) (14.1%), α-pinene (12.7%) and α-terpinol (10.7%). The main constituents of the fruit oil were eucalyptol (1,8-cineole) (34.5%),p-cymene (30.0%), α-terpinol (15.1%) and α-pinene (9.0%). Our results showed that both types of oils are rich in terms of monoterpene hydrocarbons and oxygenated monoterpenes. The leaf and fruit essential oils ofE. camaldulensissignificantly inhibited the growth of Gram-positive (Staphylococcus aureusandBacillus subtilis) and Gram-negative (Escherichia coliandStreptococcussp.) bacteria (p<0.05). The oils also showed fungicidal activity againstCandida tropicalisandC. globrata. Leaf essential oils showed more activity than fruit essential oils, probably due to the higher p-cymene concentration in leaves.

AbstractPlants from genus Seseli, have been widely used in European traditional medicine, exhibiting antibacterial, antifungal, insect repellent, emmenogogue, antiflatulence, anti-inflammatory, antinociceptive, anti-tumor, antirheumatic activities and protective effect on human lymphocytes DNA. They usually grow on mountain rocky terrains. Part of their habitat on Vidlic Mountain, located in South-east Serbia, was struck with a large wildfire. Seseli rigidum fruit essential oils (from post fire and control areas) compositions were analyzed by GC and GC-MS, identifying monoterpenes α-pinene and sabinene as most abundant. Statistical tests showed a non-significant difference in chemical composition of these two oils, but a significant difference in comparison with the herb from a geographically different origin. Antimicrobial tests showed strong activities of the oils against tested bacteria, thus confirming its administration in various inflammation processes as a quite effective remedy. Applying DPPH. and ABTS+. radical scavenging and total reducing Fe(III) to Fe(II) power assays, antioxidant characteristics of both studied essential oils were estimated as weak, though of close values. Seseli rigidum fruit essential oil was proven as a potent inhibitor of human and horse serum cholinesterase, recognizing its possible application as neural protective agent

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.

Chemical composition of the essential oils derived from Atractylodes macrocephala (AMA), Astragalus membranaceus (AME) and AMA-AME herb pair was investigated using gas chromatography-mass spectrometry (GC-MS). Antioxidant activities were evaluated by 1,1-diphenyl-2-picyrlhydrazyl (DPPH) radical-scavenging and Trolox equivalent antioxidant capacity (TEAC) assays. Forty-five, ten and forty-three components were identified in AMA, AME and AMA-AME essential oils, respectively. AMA-AME essential oil exhibited a significantly higher radical scavenging capacity than the theoretical sum of those of the respective herb essential oils ( P < 0.05). Principal component analysis showed that twenty-three components contributed to the scavenging activities against DPPH and ABTS•+ radicals. Moreover, the concentrations of these major components exhibited various increases to some extent when compared with the theoretical sum of the respective herb essential oils. These findings suggest that combination of two or more herbs might be used as a promising source of natural antioxidants in the pharmaceutical and food industries.

Myrtus communis L. is a shrub growing wild in most countries all around the Mediterranean Sea and myrtle leaf oil is useful in the perfumery and pharmaceutical industries. Nowadays, “chemotyped” essential oils are more and more appreciated. Myrtle oil from eastern and central-north Algeria belong to the “α-pinene-cineole” chemotype. In contrast, Moroccan myrtle oil displayed appreciable content of myrtenyl acetate. Therefore, it appeared crucial to investigate the composition of myrtle leaf oil from northwestern Algeria in order to ensure the homogeneity of the composition of Algerian myrtle leaf oil. The chemical composition of 42 oil samples of M. communis isolated from leaves collected in five locations from Tlemcen Province was investigated by gas chromatography (GC) in combination with retention indices, GC-mass spectroscopy, and 13C nuclear magnetic resonance spectroscopy. Yields ranged between 0.13% and 1.04% (w/w). The chemical composition of the oils was largely dominated by monoterpene hydrocarbons, with α-pinene (24.3-59.0%) and 1,8-cineole (13.2-49.5%) being the major compounds followed by limonene (3.2-19.8%). The 42 compositions were submitted to statistical analyses. The combination of hierarchical cluster analysis and principal component analysis allowed the distinction of two groups, the second group being subdivided into two subgroups. Groups and subgroups were differentiated with respect to their contents of α-pinene and 1,8-cineole and, to a lesser extent, of limonene. This study ensures that Algerian myrtle leaf oil belongs to the “α-pinene-cineole” chemotype which displays various biological activities. The observed homogeneity could be a positive point to join the international market of essential oils.
