1,8-Cineole (cineole) is a Eucalyptus leaf toxin that defends against predation by herbivores such as the brushtail possum (Trichosurus vulpecula). The aim of the current study was to characterize the pharmacokinetics of cineole in the possum to improve understanding about how possums can avoid cineole toxicity when eating a Eucalyptus diet. Nine male possums were trapped in the wild and acclim...

Secrets of the Forest: Volatiles First Discovered in Pine Trees Propagate Defense 2 Signals Within and Between Plants 3 4 Systemic acquired resistance (SAR)—a plant-wide heightened state of defense following 5 localized exposure to a pathogen—is characterized by increased salicylic acid (SA) and ROS 6 levels and elevated expression of pathogenesis-related genes. SAR depends on ENHANCED 7 DISEAS...

Eucalyptus is well reputed for its use as medicinal plant around the globe. The present study was planned to evaluate chemical composition, antimicrobial and antioxidant activity of the essential oils (EOs) extracted from seven Eucalyptus species frequently found in South East Asia (Pakistan). EOs from Eucalyptus citriodora, Eucalyptus melanophloia, Eucalyptus crebra, Eucalyptus tereticornis, E...

Isolation and characterization of leaf volatiles in Anemopsis californica (Nutt.) Hook. and Arn. (A. californica) was performed using steam distillation, solid-phase microextraction, and supercritical fluid extraction. Thirty-eight compounds were detected and identified by gas chromatography; elemicin was the major component of the leaf volatiles. While the composition of the leaf volatiles var...

Eucalyptus cinerea, known as silver dollar tree, has few descriptions in traditional medicine. Chemical composition and antimicrobial properties of the essential oils of leaves, flowers and fruits, collected seasonally, were determined by GC/MS and disk diffusion/MIC, respectively. 1,8-Cineole was the main compound, particularly in fresh leaves-Spring (74.98%), dried leaves-Spring (85.32%), flo...

the composition of the volatile oils obtained from the aerial parts of artemisia deserti krasch. and a. oliveriana j. gayex dc. was analyzed by gc and gc/ms. while the oil of a. deserti contained camphor (45.5%), 1,8-cineole (16.7%), piperitone (8.6%), ?-pinene (5.7%) and isoborneol (3.2%), the oil of a. oliveriana contained ?-thujone (65.4%), camphor (11.5%), 1,8-cineole (9.2%) and pinocavone ...

Due to the various hazards of using synthetic chemical compounds in pharmaceutics, agriculture, and industry, scientists researchers do their best explore assess new green natural from resources with potent activity. The essential oil (EO) resin collected Araucaria heterophylla Salisb. was extracted by microwave technique chemically characterized via GC-MS analysis. Furthermore, extract EO asse...

background: achillea tenuifolia lam. (compositae) with small yellow flowers and several times pinnately divided leaves in worm shape is known for many years in the folk medicine. it has been used to reduce sweating and to stop bleeding. it helps regulation of the menstrual cycle and reduces heavy bleeding and pain. materials and methods: plant material (flower, leaf and stem) was collected in k...

Background: Common sage (Salvia officinalis) is a popular culinary and medicinal herb. A literature survey has revealed that sage oils can vary widely in their chemical compositions. The purpose of this study was to examine sage essential oil from different sources/origins and to define the possible chemotypes of sage oil. Methods: Three different samples of sage leaf essential oil have been ob...

Dispersive liquid-liquid microextraction (DLLME) followed by gas chromatography-massspectroscopy (GC-MS) was used to analyses of components of floral-water of Rosmarinusofficinalis . Some effective parameters such as volume of extraction, disperser solvents andsalt effect were studied by a full factorial design for obtain the optimum condition. The maincompounds of the floral-water of Rosmarinu...
