Background: The conifer species Pinus halepensis (Pinaceae) and Tetraclinis articulata (Cupressaceae) are widely used in traditional medicine due to their health beneficial properties. Objective: This study aimed to investigate the mechanisms by which P. halepensis and T. articulata essential oils (1% and 3%) could exhibit neuroprotective effects in an Alzheimer's disease (AD) rat model, induced by intracerebroventricular (i.c.v.) administration of amyloid beta1-42 (Aβ1-42). Method: The essential oils were administered by inhalation to the AD rat model, once daily, for 21 days. DNA fragmentation was assessed through Cell Death Detection ELISA kit. Brain-derived neurotrophic factor (BDNF), activity-regulated cytoskeleton-associated protein (ARC) and interleukin-1β (IL-1β) gene expressions were determined by RT-qPCR analysis, while BDNF and ARC protein expressions were assessed using immunohistochemistry technique. Results: Our data showed that both essential oils substantially attenuated memory impairments, with P. halepensis mainly stimulating ARC expression and T. articulata mostly enhancing BDNF expression. Also, the inhalation of essential oils reduced IL-1β expression and induced positive effects against DNA fragmentation associated with Aβ1-42-induced toxicity, further contributing to the cognitive improvement in the rats with AD-like model. Conclusion: Our findings provide further evidence that these essential oils and their chemical constituents could be natural agents of therapeutic interest against Aβ1-42-induced neurotoxicity.

Mite Mortality

Varroosis is a disease of Apis mellifera L. caused by the mite Varroa destructor Anderson and Trueman. Essential oils and their chemical constituents offer a safe alternative to synthetic acaricides for the control of this mite in bee hives. The present study was conducted to evaluate anti-parasitic activity of essential oils from Thymus kotschyanus Bioss & Hohen., Mentha longifolia L., Eucalyptus camaldulensis Dehnh., and Ferula gummosa L. at concentrations of 1, 2.5, 4, and 5.5 µl/l air for 5 and 10 h. Findings indicated that mite mortality increased as oils concentration and exposure time increased. T. kotschyanus oil at 5.5 µl/l air caused a mite mortality rate of 54.4% and 84.43% after 5 and 10 h fumigation, respectively. At the same concentration and exposure time, the honey bee mortality was 0% and 7.2%, respectively. Application of M. longifolia and E. camaldulensis oils at 5.5 µl/l air resulted in 65.53% and 71.06% mortality in Varroa mites and 10.13% and 12% mortality in honey bees after 10 h exposure. Despite moderate acaricidal activity of F. gummosa oil against Varroa mite (49.69%), it was highly toxic to honey bee (30%). Also, GC/MS analysis of the oils showed that carvacrol (47.99%) and thymol (30.61%) in T. kotschyanus oil, piperitenone (36.86%), piperitenone oxide (27.53%),Cispiperitone epoxide (22.21%), and pulegone (8.38%) in M. longifoliaoil, 1,8-cineol (74.7%) and α-pinene (8.35%) in E. camaldulensis oil, and β-pinene (87.29%) in F. gummosa oil were the main chemical constituents. Collectively, our results led to a conclusion that T. kotschyanus, M. longifolia, and E. camaldulensis oils have enough potential to play an important role in integrated control programs of varroosis in apiaries.

Essential Oil Yield

The aim of the study was to characterize the chemical constituents and determine antibacterial and antioxidant activities of essential oils and three different extracts of Dryopteris marginalis. The root had essential oil yield of 0.36 % (w/w) in which 12 organic compounds representing 97.22% of the root oils were identified. Tyranton was found as the most abundant component with 77.571 % of the total concentration in the essential oil. The zones of inhibition of different organic extracts against the tested bacteria were found in the range of 6.5-15 mm. Pseudomonas was the most vulnerable with MICs of 15.62 μg/mL by both ethyl acetate and petroleum ether extract producing 3.8 mm zone of inhibition. The essential oils extracted from roots of Dryopteris marginalis showed maximum 85.29 % inhibition of radical scavenging at 2 mg/mL concentration. Among all root extracts, methanol extract exhibited 41.11 % inhibition at 2 mg/mL concentration.

Pelargonium Graveolens

Pelargonium graveolens (Geranium) is a source of the finest quality of fragrance and its essential oils are used as antibacterial, and antifungal agents. The aim of the current research is to determine chemical constituents in the essential oil of P. graveolens by GC-MS and evaluate its antidiabetic activity via α-glucosidase inhibition assay. The chemical composition of P. graveolens essential oil was determined by GC/MS and its antidiabetic activity was assessed through inhibition of α-glucosidase enzyme in in-vitro models. GC-MS analysis determines 36 chemical components in the essential oil of P. graveolens leaves, and citronellyl isovalerate (10.41 %), menthol (9.61 %), linalool (8.63 %), p-menthone (6.31 %), and geranyl tiglate (4.99 %) were recorded as major constituents. The essential oil of P. graveolens leaves showed concentration dependant inhibition of α-glucosidase enzyme ranging from 28.13±1.41 to 74.24±2.53 µg/mL for concentration ranging from 31.25 to 1000 µg/mL. The IC50 values for of P. graveolens and acarbose were found as 93.72±4.76 and 80.4±2.17 µg/mL, respectively against the α-glucosidase enzyme. The study finding explores the chemical components of P. graveolens growing in the Iraqi Kurdistan region and scientifically supported its possible use in diabetic patients for controlling postprandial hyperglycemia.

Protium aracouchini (Aubl.) Marchand [sin Icica aracouchini Aubl.], which occurs in the Adolpho Ducke Forest Reserve, in the Brazilian Amazon, was evaluated for the presence of galls, for resin exudation and the composition of the essential oils from the aerial parts and the resin. The experiment to stimulate the exudation of resin from the trunk was conducted using a 2-chloroethylphosphonic acid solution. The resin produced after 40 days and the aerial parts had their essential oils extracted in a Clevenger apparatus and the volatile chemical constituents were analyzed using GC/MS. The non-oxygenated sesquiterpenes α-copaene (21.15%) and α-gurjunene (13.69%), in addition to the oxygenated sesquiterpene spathulenol (10.32%), were detected as the majority constituents of the essential oil of the leaves, and a concentration similar to that of α-gurjunene was found in the branches (13.28%). The resin essential oil showed a high concentration of hydrocarbon monoterpenes (76.49%) with a predominance of α-pinene (17.57%) and limonene (46.11%). Four gall morphotypes were found associated with this species. The present study reports for the first time information on the volatile constituents and the resinous potential of P. aracouchini, and registers the morphotypes of the galls that help in the taxonomy of the species.
