We report the widespread occurrence of structurally diverse oleuropeyl glucose esters, including the new diester eucaglobulin B, localized specifically to the essential oil secretory cavities of myrtaceous species. Clear taxonomic patterns in the composition of cavity extracts within the genus Eucalyptus are shown with species from subgenus Symphyomyrtus dominated by oleuropeyl glucose esters a...

Essential oils, flavors, and spices constitute a large and heterogeneous group of substances to which humans are exposed. The essential oils are defined as a group of odorous principles soluble in alcohol and only to a limited extent in water. They consist of a mixture of esters, aldehydes, ketones, and terpenes. Relatively few members of this group of sub stances have been shown to cause cance...

many parameters affect essential oil yield and chemical composition of aromatic plants. for obtaining the highest quantity and quality of essential oil, it is necessary to know the proper methods of drying and distillation. the aim of this research was to investigate the influence of drying and extraction methods on the yield and chemical composition of the essential oil of eucalyptus sargentii...

in this study, penicillium digitatum, the causes of green mould disease of orange fruits, were isolated from infected fruit in bam city. antifungal activity of three different plant essential oils eucalyptus camaldulensis, zataria multiflora, myrtus communis at 50, 100, 150 and 200 ppm concentration, have been evaluated. mic (minimum inhibitory concentration) and growth inhibition zone diameter...

Because of its resistance to antibiotics, Staphylococcus aureus causes many of problems in hospital and society. As one of the main reasons of clinical infections it can cause to serious surgical and cutaneous infections and pneumonia. The inhibitory effect of the essential oils include; Eucalyptus largiflorence, E. camaldulensis, E. malliodora and E. polycarpa as a natural and herbal antimicro...
