Essential oils, EOs, are concentrated liquids with complex mixtures of volatile organic compounds that can be extracted from different plant materials. EOs have been used by humans throughout history due to their natural properties: pleasant fragrances, anti-bacterial/fungal activities. This work presents the impact pulsed electric fields, PEF, application as a pre-treatment for extraction euca...

Eucalyptus has become one of the most widely planted genera in world because its tolerance to a wide range soil types and climates, as well for many industrial, commercial medicinal uses. torquata Luehm. is plantation species frequently semi-arid arid regions ecological, forestry, ornamental melliferous interests. Based on literature, drought this was mostly directed adaptation mechanisms. Phys...

Biopolymer-based films were developed using a mixture of pullulan and agar, the fabricated film was functionalized with bioactive functional components, Pickering emulsion eucalyptus essential oil (PEU), rutin. The color PEU rutin supplemented light yellow. As result, yellowness index increased while whiteness reduced. filler showed biocompatibility pullulan/agar polymer matrix. presence materi...

In order to establish the marker constituents of the natural antioxidant food-additive Eucalyptus leaf extract, the UV-absorbing constituents of two eucalyptus leaf extracts registered as food additives (eucalyptus A and B) were investigated. Several major peaks on the reversed-phase HPLC chromatogram of eucalyptus A were characterized as gallic acid, ellagic acid, 3-O-beta-D-glucuronides of qu...

BACKGROUND The leaves of Eucalyptus globulus (eucalyptus) are used for treatment of diabetes mellitus in traditional medicine. The aim of this study was to evaluate the effects of eucalyptus in treatment of established systemic infection with Candida albicans in normal and streptozotocin-induced diabetic rats. METHODS Sixty normoglycemic male Wistar rats, weighing 200-250 g, were selected and...

Genetic variability of growth and wood chemical properties in a clonal population of Eucalyptus urophylla × Eucalyptus grandis in the Congo Garel Makouanzi, Gilles Chaix, Sophie Nourissier & Philippe Vigneron To cite this article: Garel Makouanzi, Gilles Chaix, Sophie Nourissier & Philippe Vigneron (2017): Genetic variability of growth and wood chemical properties in a clonal population of Euca...

Plant essential oils are preferred in cosmetics, medicine, food, and beverage industries for various purposes. α-Pinene is found mainly eucalyptus oils, eugenol the active ingredient clove oil, limonene major component oil of citrus fruit peels. In this study, we aimed to determine antifungal activity α-pinene, eugenol, against Saccharomyces cerevisiae yeast cells. Besides, focused on revealing...

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...

The influence of Eucalyptus plantations on the structure and composition of macroinvertebrate communities associated with the aquatic fern Salvinia auriculata Aublet were investigated in a high altitude lake bordered by either secondary Atlantic forest or Eucalyptus plantations. Comparisons of the diversity of Chironomidae (Diptera, Insecta) larvae in the littoral zone between these two vegetat...
