A protocol for the micropropagation of Eucalyptus polybractea R.T. Baker (blue mallee) using axillary bud proliferation from lignotuber-derived explants is described. Three different ages of plants were used as explant sources: glasshouse-grown seedlings, field-grown saplings, and coppice of field-grown mature lignotubers. Explants from each source initiated successfully and no significant diff...

The essential oils isolated by hydrodistillation from the leaves of two Eucalyptus gillii Maiden and E. microcarpa Subsp. macrocarpa Hook were analysed by GC and GC/MS. The main components identified in E. gillii oil were 1, 8-cineole (79.5%), trans-pinocarveol (8%) and ?-pinene (2.7%), and in E. microcarpa were 1, 8-cineole (77.3%), ?-pinene (5.6%) and terpin-1-ol (5.1%). Oils with high conten...

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...

A total of thirty endophytic fungi were isolated from leaves and twigs of Eucalyptus globulus and Eucalyptus citriodora. Among thirty endophytic fungal isolates, four (P3MT1, P3MT2, OP4MT2 and P7ML2) are consistently producing compounds which are inhibiting Pseudomonas aeroginosa, Mycobacterium smegmatis and Candida albicans even after 10 generations tested under dual culture, well diffusion an...

Essential oils (EOs) from Cymbopogon citratus (CC), Eucalyptus citriodora (EC), Eucalyptus camaldulensis (ED), and Citrus sinensis (CS) were obtained by hydrodistillation process. The EOs were evaluated in vitro for activity against Trypanosoma brucei brucei (Tbb) and Trypanosoma evansi (T. evansi). The EOs were found to possess antitrypanosomal activity in vitro in a dose-dependent pattern in ...

The aim was to investigate the effects of volatile fraction of essential oils from Picea abies, Eucalyptus globulus, Rosmarinus officinalis and volatile fraction of Abies sibirica oil on fungi isolated from apple, leek, carrot, onion. Researches were made in 2008–2009. Tested fungi were as follows: Penicillium roqueforti, Aspergillus flavus, Aspergillus flavus var. oryzae, Mortierella hyalina v...

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...

Eucalyptol (1,8-cineole) compound contained in eucalyptus oil has the potential to inhibit viral infection pathways, as an antimicrobial and immunoregulator. Therefore, development of oil-based effervescent health drinks is urgently needed relieve symptoms being infected a virus during this pandemic. However, volatility quite high, so nano-based encapsulation method slow release these volatile ...

Eucalyptus species are widely planted for reforestation in subtropical China. However, the effects of Eucalyptus plantations on the regional water use remain poorly understood. In an age sequence of 2-, 4- and 6-year-old Eucalyptus plantations, the tree water use and soil evaporation were examined by linking model estimations and field observations. Results showed that annual evapotranspiration...
