background and objectives: the chemical composition and antimicrobial activity of bitter orange (citrus aurantium) leaf, ripe and unripe peel essential oils, cultivated in southwest of iran, were investigated. materials and methods: the analysis of chemical composition of hydro-distilled essential oils was carried out by gc-ms. the disc diffusion and broth micro-dilution were used to assay the ...

Aedes aegypti and Anopheles gambiae are two mosquito species that represent significant threats to global public health as vectors of Dengue virus and malaria parasites, respectively. Although mosquito populations have been effectively controlled through the use of synthetic insecticides, the emergence of widespread insecticide-resistance in wild mosquito populations is a strong motivation to e...

In this study antifungal activities of essential oils from different tissues of Japanese cedar (Cryptomeria japonica D. Don) against four wood decay fungi and six tree pathogenic fungi were investigated. In addition, the yields of essential oils obtained by water distillation were compared and their constituents determined by GC-MS analyses. The yield of essential oils from four tissues of Japa...

there have been efforts to overcome the problem in treatment of cancer using medicinal plants. it has been shown that citrus essential oil of contains different terpens with antitumor activities. in this study we sought to determine the cytotoxicity of essential oils of iranian citrus limon (l.), c. medica (l.), c. sinsensis (l.) peels on cancer cell lines. essential oils were prepared by hydro...

Essential oils have antifungal and antipathogenic effects and therefore are targets in plant pathology research for their potential uses as natural substitutes for inorganic plant pesticides. Beauveria bassiana, an entomopathogenic fungus, can endophytically colonize a vast number of plant species and trigger induced systemic resistance against plant pathogens. Spore germination is the most vul...

The molluscicidal activity of essential oils from two endemic (Juniperus brevifolia; Laurus azorica) and three introduced (Hedychium gardnerianum; Pittosporum undulatum; Psidium cattleianum) Azorean plants against the snail Radix peregra was studied under laboratory conditions. Essential oils from leaves of H. gardnerianum, L. azorica and J.brevifolia presented promising molluscicidal activity ...
