The essential oils from leaves, twigs and stems of large trees and shrub-like trees of Thuja sutchuenensis were extracted by hydrodistillation and supercritical fluid extraction, and analyzed by GC and GC–MS. The essential oil composition differed significantly among the three organs, as well as between large trees and shrub-like trees. Furthermore, consistent with the eastern Asia–North American disjunct distribution of the genus, many differences in the essential oil composition between T. sutchuenensis and other Thuja species were apparent. The essential oils exhibited a certain degree of antifungal activity against six strains of human pathogenic fungi.

Basil Oil

The focus of the present study was on the influence of season on yield, chemical composition, antioxidant and antifungal activities of Omani basil ( Ocimum basilicum) oil. The present study involved only one of the eight Omani basil varieties. The hydro-distilled essential oil yields were computed to be 0.1%, 0.3% and 0.1% in the winter, spring and summer seasons, respectively. The major components identified were L- linalool (26.5 - 56.3%), geraniol (12.1 - 16.5%), 1,8-cineole (2.5 - 15.1%), ρ-allylanisole (0.2 - 13.8%) and DL-limonene (0.2 -10.4%). A noteworthy extra component was β- farnesene, which was exclusively detected in the oil extracted during winter and spring at 6.3% and 5.8%, respectively. The essential oil composition over the different seasons was quite idiosyncratic, in which the principal components of one season were either trivial or totally absent in another. The essential oil extracted in spring exhibited the highest antioxidant activity (except DPPH scavenging ability) in comparison with the oils from other seasons. The basil oil was tested against pathogenic fungi viz. Aspergillus niger, A. fumigatus, Penicillium italicum and Rhizopus stolonifer using a disc diffusion method, and by determination of minimum inhibitory concentration. Surprisingly high antifungal values were found highlighting the potential of Omani basil as a preservative in the food and medical industries.

Essential oils were hydrodistilled from six Zieria species, including two previously not investigated: Z. floydii and Z. odorifera subsp. williamsii, and characterized using GC-MS. Additionally, solvent extracts of leaf material from five of these species were prepared using n-hexane, acetone and methanol as solvents, respectively. These solvent extracts were examined, along with essential oils, for antibacterial activity using micro titer plate broth dilution assays. Antifungal activity against pathogenic Trichophyton species responsible for dermal infections such as Tinea and Kangaroo Pox (uncommon), was examined using a similar method. Results of essential oil characterizations are relatively consistent with those previously reported. Interestingly, the essential oil composition of Z. floydii showed car-3-en-2-one at a concentration of 71%, similar to that observed in a previous study for Z. furfuracea and Z. granulata, thus complementing the observations of A.G. Floyd that Z. floydii is morphologically allied with these two species (CANB 598758). Antimicrobial assays demonstrated relatively high antibacterial and antifungal activity, using both essential oils and solvent extracts. This is particularly true for the n-hexane extract from Z. smithii. We therefore conclude that Zieria species may be a useful source for the development of antiseptic, cosmaceutical and/or topical nutraceutical products. In addition, they may well serve as a source of further novel, purified compounds providing scaffolds for pharmaceutical development in the future.

The aerial parts of Ocimum gratissimum L. (Lamiaceae) harvested in Togo was steam-distilled and investigated for essential oil composition (GC and GC/MS) and in vitro antifungal activities. Thymol (31.79 %), p-cymene (15.57 %) and γ-terpinene (12.34 %) and were the major components of the oil. Other notable components identified in this oil were myrcene (6.94 %) and α-thujene (6.11 %).The in vitro antifungal activity was recorded with the minimum inhibitory concentrations (MICs) ranging from 80 to 150 µl.l-1, 150 to 500 µl.l-1  and from 100 to 150 µl.l-1 respectively on dermatophytes, imperfect filamentous fungi and pathogenic yeasts. Likewise, on tested fungi the minimum fungicidal concentration (MFC) varied from 300 µl.l-1 to 500 µl.l-1, 500 to 700 µl.l-1 and from 250 to 300 µl.l-1, respectively on dermatophytes, imperfect filamentous fungi and pathogenic yeasts.

The present study reports the results of gas chromatography-mass spectrometry (GC/MS) analyses of the essential oil from flowering aerial parts of Cotinus coggygria Scoop. (Anacardiaceae), as well as its in vitro antifungal activity against nine plant pathogenic fungi. Moreover, the essential oil was evaluated for its antifungal activity using the agar dilution method, and also MICs (minimum inhibitory concentrations) and MFCs (minimum fungicidal concentrations) were determined. The major compounds identified by GC-MS were limonene (49.2%), (Z)-β-ocimene (13.6%), α-pinene (8.8%) and (E)-β-ocimene (5.9%). The oil showed in vitro antifungal activity against some species of the Fusarium genus, Botrytis cinerea, and Alternaria solani. Our study indicates that the oil of C. coggygria could be used as a control agent for plant pathogenic fungi in natural formulations.

The major components of the essential oil of Piper divaricatum from Marajó Island, PA, Brazil, were methyleugenol (63.8%) and eugenol (23.6%), which were identified by GC and GC-MS. Essential oils of Piper species from the Brazilian Amazon are rich in either mono- and sesquiterpenes or phenylpropanoids, as seen in this study. The oil was able to scavenging the DPPH radical, displaying an inhibition varying from 19% to 74%, with an EC50 value of 16.2 ± 1.9 μg mL−1. In the bleaching of β-carotene, the inhibition of the oil oxidation was 60.0 ± 2.7%. The oil gave minimum inhibitory concentrations for the fungi Cladosporium cladosporioides and C. sphareospermum of 0.5 μg and 5.0 μg, respectively. The oil also showed significant brine shrimp larvicidal activity (LC50, 38.8 ± 0.8 μg mL−1).
