Background Eucalyptus trees (family Myrtaceae) are well-known for their high foliar content of several classes of secondary metabolites and these have a strong effect on the feeding patterns of several species of marsupials and at least some insects. Best known are the essential oils, which is mostly a mixture of terpenoids, but there are also significant concentrations of flavonoid and formyla...

gerbera cut flowers is one of the important and popular cut flowers in the world that regardless of increasing production of this plant in iran, the duration of its life is short due to rapid wilting petals and bending neck of flower. to increase vase life of gerbera cut flowers cv. ‘alain ducasse’, the essences of eucalyptus and rosa damascena, the combination of these two essences at a concen...

BioUD is an arthropod repellent that contains the active ingredient 2-undecanone originally derived from wild tomato plants. Repellency of BioUD was compared with five commercially available arthropod repellents against the ticks Amblyomma americanum (L.) and Dermacentor variabilis Say in two-choice bioassays on treated versus untreated cotton cheesecloth. Overall mean percentage repellency aga...

A total of 23 volatile constituents was identified and characterized by GC and GC-MS in the volatile essential oil extracted from intact (juvenile and adult) and fallen (senescent and leaf litter) leaves of lemon-scented eucalyptus (Eucalyptus citriodora Hook.). The leaves differed in their pigment, water and protein content, and C/N ratio. The oils were, in general, monoterpenoid in nature wit...

background: essential oils, as secondary plant compounds, present a safer alternative to conventional insecticides in insect control programs. so five essential oils including eucalyptus, mint, yarrow, oregano and rosemary oils were evaluated against the brown-banded cockroach supella longipalpa . methods : evaluation was done against the 3 rd and 4 th instar nymphs using three bioassay methods...

  Background: The genus Eucalyptus (family Myrtaceae) comprises well-known plants of over 600 species of trees. Although most of the plants are native to Australia, numerous species have been introduced to other parts of the world, including Iran, as economic and ornamental trees in forest trial provenances, where the plants have become source of important fast-growing hardwood trees and Eucaly...

The effects of essential oil from Eucalyptus camaldulensis flowers oil on melanogenesis and the oil's antioxidant characteristics were investigated. Assays of mushroom and cellular tyrosinase activities and melanin content of mouse melanoma cells were performed spectrophotometrically, and the expression of melanogenesis-related proteins was determined by Western blotting. The possible signaling...

The present work comprises the formulation and evaluation delivery system of transdermal drug with a view of developing and preparing a losartan potassium releasing system utilizing natural oils as permeation enhancers for transdermal applications. Matrix systems were prepared by using polyvinyl pyrrolidine and ethyl cellulose (EC) polymers by incorporating dibutyl phthalate as plasticizer and ...
