A liquid chromatography-diode array detection-electrospray ionization mass spectrometric (HPLC– PDA–ESI/MS/MS) method was used for separation and characterization of the phytoconstituents of the aqueous acetone leaf extract of Eucalyptus camaldulensis Dehnh (Myrtaceae). The employed method was optimized for separation, identification and quantification of fifty six compounds including ellagitan...

BACKGROUND Asthma is one of the most common chronic diseases in modern society and it is evident that its incidence and severity are increasing, however very little is known about the plants used in the management of the disease. This study therefore aimed to document the plants usage in the Togolese traditional medicine to treat asthma. METHODOLOGY From January to June 2015, an ethnobotanica...

Stressful episodic weather is likely to affect the C balance of trees as the climate changes, potentially altering survival. However, the role of elevated CO2 concentration ([CO2]) in tolerating off-season episodic extremes is not clear. We tested for interactive effects of elevated CO2 and springtime heat stress on photosynthesis for seven genotypes of Eucalyptus camaldulensis Dehnh. var. cama...

Background Real time quantitative reverse transcription PCR (realtime qRT-PCR) is an established technique for quantification of mRNA and has been extensively used for gene regulation studies in plants. However, there are inherent challenges associated with the technique such as variability of RNA and extraction protocols, different rates of reverse transcription and PCR efficiencies. This dema...

In the current study, the mosquito larvicidal activity of leaf essential oils and their constituents from two eucalyptus species (Eucalyptus camaldulensis and Eucalyptus urophylla) against two mosquito species, Aedes aegypti and Aedes albopictus, was investigated. In addition, the chemical compositions of the leaf essential oils were analyzed using gas chromatography-mass spectrometry. Results ...

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...
