Abstract
This study examined the chemical composition and antimicrobial activities of essential oils isolated from the leaves, twigs, and fruits of Neolitsea sericea var. aurata from Taiwan. The major compounds responsible for antimicrobial activity were isolated and identified. The leaf, twig, and fruit essential oils were obtained through hydrodistillation in a Clevenger-type apparatus and were characterized through gas chromatography (GC) with flame ionization detection (GC/FID) and GC/mass spectrometry (GC/MS). The major compounds were ( E)-β-ocimene (49.3%) and sericenine (31.6%) in the leaf oil; ( E)-β-ocimene (73.7%), α-cadinol (6.8%), and α-muurolol (4.0%) in the twig oil; and ( E)-β-ocimene (84.7%) in the fruit oil. The twig oil exhibited the strongest antibacterial and antifungal activities. We isolated α-cadinol and α-muurolol, the main components of NTO4 fraction, and used them in antimicrobial tests; the two compounds exhibited excellent antimicrobial activities. The twig essential oil contains α-cadinol and α-muurolol and exhibited excellent antimicrobial activities against food-borne pathogens; thus, they are worthy of further research and development.

Abstract
In this study, the chemical composition and antimicrobial activity of the essential oil (EO) extracted from leaves of the Moroccan endemic plant Argania spinosa were investigated for the first time, to the best of our knowledge. In addition, the EO antimicrobial activity was evaluated in combination with two known antibiotics (ciprofloxacin and fluconazole), in order to ascertain possible synergistic effects. The chemical composition analyzed by GC/MS showed that A. spinosa EO was characterised by the abundance of geranyl acetate (19.18%), methyleugenol (10.98%), linalyl acetate (10.59%) and eucalyptol (8.49%), and monoterpene hydrocarbons was the major class. EO showed an antimicrobial potential against all tested microorganisms. The highest activity was recorded against Gram positive bacteria and yeasts with MICs ranging from 7.75 to 15.5 mg/mL and from 3.88 to 7.75 mg/mL, respectively. The Gram negative bacteria were the most resistant with MICs of 31 mg/mL. The mixture of EO at sub-inhibitory concentrations with conventional drugs exhibited a significant decrease in their individual MICs from 4 to 32 fold. The highest level of synergy was observed for ciprofloxacin against Staphylococcus aureus, Bacillus subtilis and Escherichia coli. Despite the antimicrobial activity of A. spinosa EO is weak, the results of the current study suggest a potential synergy between EO and antibiotics in the goal to modulate drug resistance.

Anti-Inflammatory Activities of Leaf Oil from Cinnamomum subavenium In Vitro and In Vivo. BIOMED RESEARCH INTERNATIONAL 2019; 2019:1823149. [PMID: 30915347 PMCID: PMC6402240 DOI: 10.1155/2019/1823149] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/17/2018] [Revised: 01/02/2019] [Accepted: 01/13/2019] [Indexed: 11/18/2022]
Abstract
The study determined the chemical constituents and anti-inflammatory effects of leaf oil from Cinnamomum subavenium (CS-LO) that has been used in folk medicine to treat various symptoms including inflammation. The anti-inflammatory effects of the oil were evaluated by LPS-stimulated RAW264.7 cells and the Carr-induced hind mouse paw edema model, respectively. In vitro, nitric oxide (NO), prostaglandin E2 (PGE2), TNF-α, IL-6, and IL-1β were significantly decreased by CS-LO, and the expression of nuclear factor-κB (NF-κB) protein was blocked as well. In in vivo, the malondialdehyde (MDA) and paw edema levels were decreased by CS-LO, and the same result came up on the NO and tumor necrosis factor (TNF-a) of serum at the 5th h after Carr injection. In addition, iNOS and COX-2 immunoreactive cells of the paw tissue were decreased significantly by CS-LO (200 mg/kg) in histological examination. The present findings indicated that CS-LO have anti-inflammatory properties, and the effects might be caused through inhibiting iNOS, COX-2, TNF-α, IL-1β, and IL-6 expression via affecting NF-κB pathway, which will provide a power scientific basis for CS-LO to be used as the treatment of inflammatory diseases.

Abstract
Cnnamomum wightii is an endemic species of the Western Ghats, India and is used in Ayurveda and Siddha systems of medicine. Its bark and leaves are adulterated with commercial cinnamon in southern India. Despite its medicinal and commercial importance, the species remains underexplored. The objective of the present work was to screen the chemical composition, in vitro antioxidant, α-amylase and α-glucosidase inhibitory activities of the leaf essential oil of C. wightii collected from different populations. GC-FID and GC-MS analyses of the leaf essential oils from seven accessions enabled the identification of a total of 70 constituents, of which only 16 compounds were present in all samples. Eleven major constituents (> 5%) were identified, of which only linalool and spathulenol were present in all accessions as major constituents. Among seven accessions, essential oil from Parson's valley, Nilgiris exhibited better antioxidant activity with IC50 values of 2.552 ± 0.13 and 3.485 ± 0.09 mg/mL for ABTS and DPPH respectively. The essential oil from Korakundah, Nilgiris showed better hypoglycemic activity with IC50 values of 1.617 ± 0.02 and 1.146 ± 0.02 mg/mL for α-amylase and α-glucosidase inhibitory activities respectively. The leaf essential oils of C. wightii may be used in nutraceutical products focusing diabetes mellitus as the moderate inhibition of the metabolic enzymes has the advantage of slow release of glucose.

Abstract
The essential oils of Cinnamomum griffithii and C. macrocarpum were analyzed by GC and GC–MS and evaluated for their antioxidant and anticholinesterase activities. The essential oils of leaf and bark of C. griffithii were characterized by the presence of 30 components, with methyl eugenol (38.5–43.8%) as the major component. A total of 11 components were characterized in the leaf and bark of C. macrocarpum essential oil with the most abundant component was safrole (54.5–59.5%). The bark oil of C. griffithii demonstrated significant activity on DPPH (IC50 73.4 μg/mL) and a high phenolic content (192.0%), while the leaf oil inhibited oxidation of β-carotene/linoleic acid with an inhibition value of 65.5 μg/mL. Acetylcholinesterase and butyrylcholinesterase inhibition were assessed and the results showed that C. macrocarpum bark oil exhibited significant activity with inhibition values of 55.8% and 66.1%, respectively at a concentration of 1 mg/mL.

Abstract
Five dibenzocycloheptatrienes (1-3, 5, and 6) and one dibenzocycloheptadiene (8) together with 16 known compounds were isolated from the leaves of Cinnamomum subavenium. Application of HPLC-SPE-NMR to a selected fraction afforded two additional dibenzocycloheptatrienes (4, 7). The glycosides 2-7 comprise two diastereomers because of the chiral glycosyl moiety and the axial chirality of the biphenyl system. Their structures were elucidated via ECD and 2D NMR analyses and chemical degradation. Subavenosides D (5) and E (6) showed moderate inhibitory activity against α-glucosidase type IV from Bacillus stearothermophilus with IC₅₀ values of 50.7 and 19.0 μM, respectively.

Abstract
The hydrodistilled leaf essential oil of Machilus philippinensis was analyzed to determine its composition and yield. Seventy compounds were identified, the main ones being β-caryophyllene (13.6%), α-pinene (12.0%), α-cadinol (7.4%), cis-ocimene (7.0%), spathulenol (5.6%), (E)-nerolidol (5.3%), tau-cadinol (4.8%) and β-pinene (4.5%). Monoterpene hydrocarbons (36.1%) and oxygenated sesquiterpenes (33.0%) were the predominant groups of compounds. The leaf oil exhibited excellent anti-wood-decay fungal activities.
